How Google and NVIDIA are teaming up to solve real-world problems with AI

My venture capital job places me at the intersection of burgeoning technologies and funding new businesses. As general counsel of Alphabet’s CapitalG, I’m responsible for our fund’s legal work, and I work with the growth team to help our portfolio companies accelerate the growth of their businesses.
I’ve also had the privilege to lead an Alphabet-wide team focused on investing in Black-led VC funds, startups and organizations supporting Black entrepreneurs. As racial equity is inextricably linked to economic opportunity, last year, Google committed to making an investment to promote increased capital access and wealth generation in the Black community.
My team is responsible for allocating these funds among the many well-deserving potential recipients. This cross-Alphabet team, including people from Google, CapitalG and GV, met with numerous Black-led venture capital firms and Black entrepreneurs to identify recipients of the funds and better understand their needs.
Through this process, it was apparent that funding alone isn’t enough. So teams across Google and Alphabet have come together to provide the identified Black-led VC firms and their portfolio companies access to Alphabet’s people, network and technologies, as well.
To date, we have committed $60 million of capital to Black-led organizations and we’ll provide access to a suite of support for them and for their portfolio companies. Teams from across Alphabet will continue to work together to identify and invest in additional Black-led organizations, and Google will invest an additional $40 million in Black-led startups and investment firms by the end of the year.
We hope Google’s commitments prompt more investments from the industry and create a larger pool of capital to put dollars in the hands of Black founders. For example, since we announced the U.S. recipients of the $5 million Google for Startups Black Founders Fund in October, these founders have collectively raised over $25 million in capital from investors outside of Google.
Here are the organizations to which we have committed $60 million in capital to date:
Black-led venture capital firms:
Collab Capital:an Atlanta-based fund for Black founders seeking capital, who value profitability, ownership and optionality.
Concrete Rose:a Bay Area-based investment fund focused on using financial and social capital to build exceptional early-stage companies and close gaps for underrepresented talent.
Noemis Ventures:a New York-based fund focused on early-stage companies in the fintech, marketplace and AI sectors.
Plexo Capital: a Bay Area-based investment firm which makes direct investments in diverse startups.
Reign Ventures: a New York and Miami-based early-stage venture capital firm that focuses on investments in consumer tech and software companies founded by women and people of color.
Slauson & Company:a Los Angeles-based fund set up to invest in the next generation of entrepreneurs driving economic inclusion.
Black-led startups:
CityBlock Health: a New York-based startup focusing on providing care to Medicaid and dual-eligible patients.
Translation / UnitedMasters: a New York-based creative brand advertising agency focused on the intersection of brands with music, sports and popular culture.
Beyond funding, we’re providing these recipients with access to Alphabet training and advising sessions to help them grow their businesses. CapitalG uses a very similar approach to help hyper-growth stage companies overcome the biggest challenges as they get bigger. Along with leaders across Alphabet, Google for Startups, Cloud for Startups and Partnership Solutions, we have put together a suite of offerings that include Google Ads and Cloud support, weekly office hours and one-on-one advising with Alphabet leaders.
Other initiatives include Google-facilitated training programs focused on founder development, access to Google’s machine-learning training program taught by Google engineers and sales training. In addition to tactical support, each of these organizations is taking part in our speaker series and virtual social events to foster connections between fund managers, portfolio companies and the Alphabet family.
Jackson Georges Jr and Jamie Rosen from CapitalG, along with Ruth Ruberwa and Kristin Sills from Google, kick off our partnership with Simeon Iheagwam, Founder and Managing Partner of Noemis Ventures.
Together, we hope these new investments and access to Alphabet’s knowledge and network will help Black founders and Black-led VC firms grow their businesses and create sustained economic impact for their communities and the world at large.

For more than 20 years, Google's products have improved the lives of people all over the world. Operating our business in an environmentally and socially responsible way has been a core value since our founding in 1998. Google has been carbon neutral since 2007 and we’ve matched our entire electricity consumption with renewables for the past three years. We continue to make major investments in affordable housing and have made a number of significant commitments to promote racial equity.
Today, as part of a $10 billion debt offering, we have issued $5.75 billion in sustainability bonds, the largest sustainability or green bond by any company in history. Although a number of companies have issued green bonds (directed solely to environmental uses), sustainability bonds differ in that their proceeds support investment in both environmental and social initiatives. Such bonds are an emerging asset class and we hope this transaction will help develop this new market. We’re encouraged that there was such strong demand for these bonds from investors—they were significantly oversubscribed.
The proceeds from these sustainability bonds will fund ongoing and new projects that are environmentally or socially responsible and enable investors to join us in tackling critical issues. We believe that these investments benefit our communities, employees and stakeholders, and are an important part of fulfilling Google’s mission and goal of creating value over the long term.
For more than a decade, we’ve worked to make Google data centers some of the most efficient in the world by optimizing our use of energy, water, and materials. Today, on average, a Google data center is twice as energy efficient as a typical enterprise data center. Compared with five years ago, we now deliver around seven times as much computing power with the same amount of electricity.
Combating climate change requires transitioning to a clean energy economy. To date, we have committed approximately $4 billion to purchase clean energy from more than 50 wind and solar projects globally through 2034. Next, we are focused on our longer term vision to source carbon-free energy for our operations 24 hours a day, seven days a week; this means matching our energy consumption with clean energy for each of our data centers around the world on an hour-by-hour basis.
Since the beginning, we've focused on the impact of our workplaces: from how we build our offices to preventing food waste in our cafes. Today, more than 13 million square feet of Google offices are LEED certified.
We’re working to mitigate carbon emissions and take cars off the road by promoting the use of EVs and bicycles. By using Google shuttles in the Bay Area, we saved 40,000+ metric tons of CO2 emissions—equivalent to taking 8,760 cars off the road every work day.
We strive to be a good neighbor in the places we call home. To address the lack of affordable housing in the Bay Area, we made a $1 billion commitment to invest in housing and expect to help build 20,000 residential units, of which at least 5,000 will be affordable.
COVID-19 has taken a devastating toll on many businesses. To help we made an $800+ million commitment to small- and medium-sized businesses, health organizations, governments, and health workers on the frontlines. We’ve also partnered with Opportunity Finance Network (OFN) to provide low-interest loans to community development financial institutions, who in turn provide loans to small businesses in underserved communities in the U.S., and are working with the American Library Association to create entrepreneurship centers across the U.S.
Our Sustainability Bond Framework will guide our investments. To ensure transparency and alignment with the framework, we'll report back annually on which projects have been funded from the bonds' proceeds and their expected impact.
This is the next chapter in our commitment to a more sustainable future for everyone.
Our very first founders’ letter in our 2004 S-1 began:
“Google is not a conventional company. We do not intend to become one. Throughout Google’s evolution as a privately held company, we have managed Google differently. We have also emphasized an atmosphere of creativity and challenge, which has helped us provide unbiased, accurate and free access to information for those who rely on us around the world.”
We believe those central tenets are still true today. The company is not conventional and continues to make ambitious bets on new technology, especially with our Alphabet structure. Creativity and challenge remain as ever-present as before, if not more so, and are increasingly applied to a variety of fields such as machine learning, energy efficiency and transportation. Nonetheless, Google’s core service—providing unbiased, accurate, and free access to information—remains at the heart of the company.
However, since we wrote our first founders’ letter, the company has evolved and matured. Within Google, there are all the popular consumer services that followed Search, such as Maps, Photos, and YouTube; a global ecosystem of devices powered by our Android and Chrome platforms, including our own Made by Google devices; Google Cloud, including GCP and G Suite; and of course a base of fundamental technologies around machine learning, cloud computing, and software engineering. It’s an honor that billions of people have chosen to make these products central to their lives—this is a trust and responsibility that Google will always work to live up to.
And structurally, the company evolved into Alphabet in 2015. As we said in the Alphabet founding letter in 2015:
“Alphabet is about businesses prospering through strong leaders and independence.”
Since we wrote that, hundreds of Phoenix residents are now being driven around in Waymo cars—many without drivers! Wing became the first drone company to make commercial deliveries to consumers in the U.S. And Verily and Calico are doing important work, through a number of great partnerships with other healthcare companies. Some of our “Other Bets” have their own boards with independent members, and outside investors.
Those are just a few examples of technology companies that we have formed within Alphabet, in addition to investment subsidiaries GV and Capital G, which have supported hundreds more. Together with all of Google’s services, this forms a colorful tapestry of bets in technology across a range of industries—all with the goal of helping people and tackling major challenges.
Our second founders’ letter began:
“Google was born in 1998. If it were a person, it would have started elementary school late last summer (around August 19), and today it would have just about finished the first grade.”
Today, in 2019, if the company was a person, it would be a young adult of 21 and it would be time to leave the roost. While it has been a tremendous privilege to be deeply involved in the day-to-day management of the company for so long, we believe it’s time to assume the role of proud parents—offering advice and love, but not daily nagging!
With Alphabet now well-established, and Google and the Other Bets operating effectively as independent companies, it’s the natural time to simplify our management structure. We’ve never been ones to hold on to management roles when we think there’s a better way to run the company. And Alphabet and Google no longer need two CEOs and a President. Going forward, Sundar will be the CEO of both Google and Alphabet. He will be the executive responsible and accountable for leading Google, and managing Alphabet’s investment in our portfolio of Other Bets. We are deeply committed to Google and Alphabet for the long term, and will remain actively involved as Board members, shareholders and co-founders. In addition, we plan to continue talking with Sundar regularly, especially on topics we’re passionate about!
Sundar brings humility and a deep passion for technology to our users, partners and our employees every day. He’s worked closely with us for 15 years, through the formation of Alphabet, as CEO of Google, and a member of the Alphabet Board of Directors. He shares our confidence in the value of the Alphabet structure, and the ability it provides us to tackle big challenges through technology. There is no one that we have relied on more since Alphabet was founded, and no better person to lead Google and Alphabet into the future.
We are deeply humbled to have seen a small research project develop into a source of knowledge and empowerment for billions—a bet we made as two Stanford students that led to a multitude of other technology bets. We could not have imagined, back in 1998 when we moved our servers from a dorm room to a garage, the journey that would follow.
Hi everyone,
When I was visiting Googlers in Tokyo a few weeks ago I talked about how Google has changed over the years. In fact, in my 15+ years with Google, the only constant I’ve seen is change. This process of continuous evolution -- which the founders often refer to as "uncomfortably exciting" -- is part of who we are. That statement will feel particularly true today as you read the news Larry and Sergey have just posted to our blog.
The key message Larry and Sergey shared is this:
While it has been a tremendous privilege to be deeply involved in the day-to-day management of the company for so long, we believe it’s time to assume the role of proud parents—offering advice and love, but not daily nagging!

In addition, we plan to continue talking with Sundar regularly, especially on topics we’re passionate about!
I first met Larry and Sergey back in 2004 and have been benefiting from their guidance and insights ever since. The good news is I’ll continue to work with them -- although in different roles for them and me. They’ll still be around to advise as board members and co-founders.
I want to be clear that this transition won't affect the Alphabet structure or the work we do day to day. I will continue to be very focused on Google and the deep work we’re doing to push the boundaries of computing and build a more helpful Google for everyone. At the same time, I’m excited about Alphabet and its long term focus on tackling big challenges through technology.
The founders have given all of us an incredible chance to have an impact on the world. Thanks to them, we have a timeless mission, enduring values, and a culture of collaboration and exploration that makes it exciting to come to work every day. It’s a strong foundation on which we will continue to build. Can’t wait to see where we go next and look forward to continuing the journey with all of you.
- Sundar
Editor's note: This month marks the 50th anniversary of the Apollo 11 mission landing on the moon. As part of Google's celebration of this historic event, we asked X's Astro Teller to share his thoughts on moonshots. This post was also published on X's blog.
In the fall of 2010, I asked Larry Page a series of questions to find out what he wanted X’s purpose to be. “Is X a research center?” No, Larry said. “A philanthropic organization?” No. “An incubator?” No. “Are we solving Google’s problems?” No. Eventually, I asked, “Are we taking moonshots?” And he smiled and said, “YES.”
While I confess I hadn’t fully thought through the question when I asked it, the word’s sense of audacity and extreme difficulty spoke to both of us. And it was the seed of X’s identity as a moonshot factory, with a mission of repeatedly developing far-out, sci-fi-sounding technologies that might someday make the world a radically better place. So as we celebrate the 50th anniversary of the Apollo 11 mission this month, here’s some of the other inspiration I’ve taken from the teams who put a person on the moon.
A commemorative sand mandala by Andres Amador at a celebration of the 50th anniversary of the moon landing at X headquarters
Our use of the term “moonshot” isn’t literal; it’s more of an emotional blueprint. A moonshot is about looking beyond where you can actually see and envisioning an answer that doesn't seem reasonable—and pursuing it anyway. It’s about doing things that sound undoable but if done could redefine humanity.
In the early 1960’s, spacecraft for moon landings didn’t exist. There were no spacesuits, no space snacks, no computers for space navigation—plenty of reasons, in other words, to scoff at President Kennedy’s bold vision. But he made a powerful choice: to be an optimist and ask for something that, if possible at all, would require a radical reimagining of what space flight could be.
Perspective-shifting is one of X’s most deeply held principles. It’s not just about having an idea that sounds like science fiction (though we do reject a lot of ideas for not sounding impossible enough!). We look for a new way of thinking that avoids the usual methods and obstacles—like beaming Internet from balloons or free-space-optical stations rather than running fiber-optic cable through jungles and mountains. When you let your imagination run free and then run experiments to see whether your hypothesis could actually work, you can uncover surprising new approaches.
Growing up there were three events I wished I had been part of. The first was the work led by Alan Turing and others during WWII to build the first real computer and the decryption process that led to modern computer science. The second, which my grandfather was a part of, was the Manhattan Project; work on the atomic bomb gave rise to the first electronic general purpose computer. The third was the Apollo space missions. These three special gatherings symbolized for me that the seemingly impossible can happen when passionate and talented people come together with urgency and determination.
The secret? It’s easier to get people to work on making something 10X better than to get them to help make it 10 percent better. Huge problems fire up our hearts as well as our minds. When you’re aiming for a 10X gain, you can’t just slog through it. You have to find whole new ways of doing things, and lean on bravery and creativity—the kind that, literally and metaphorically, can put a person on the moon.
Huge problems fire up our hearts as well as our minds.
More than 400,000 people made the Apollo mission possible—from mechanical engineers to fashion designers, with teams reaching from New England to California. Behind the millions of rocket components were many more millions of prototypes and experiments—all the rough ideas and uncomfortable moments necessary to solve problems no one had ever faced before. This was creativity in action, at a massive scale.
The lone inventor having a eureka moment is largely a myth; innovation comes from great teams where everyone feels comfortable raising questions and sharing their views. The more people a project has from a wide range of backgrounds and communities, the more fresh perspectives and creative ideas we can generate—and the better we’ll all be. At X, that’s why former rocket scientists work alongside concert pianists and puppeteers, and marine biologists mingle with physicists and machine learning experts.
Imagine trying to have a conversation with your friends about the news you read this morning, but every time you said something, someone shouted in your face, called you a nasty name or accused you of some awful crime. You’d probably leave the conversation. Unfortunately, this happens all too frequently online as people try to discuss ideas on their favorite news sites but instead get bombarded with toxic comments.
Seventy-two percent of American internet users have witnessed harassment online and nearly half have personally experienced it. Almost a third self-censor what they post online for fear of retribution. According to the same report, online harassment has affected the lives of roughly 140 million people in the U.S., and many more elsewhere.
This problem doesn’t just impact online readers. News organizations want to encourage engagement and discussion around their content, but find that sorting through millions of comments to find those that are trolling or abusive takes a lot of money, labor, and time. As a result, many sites have shut down comments altogether. But they tell us that isn’t the solution they want. We think technology can help.
Today, Google and Jigsaw are launching Perspective, an early-stage technology that uses machine learning to help identify toxic comments. Through an API, publishers—including members of the Digital News Initiative—and platforms can access this technology and use it for their sites.
Perspective reviews comments and scores them based on how similar they are to comments people said were “toxic” or likely to make someone leave a conversation. To learn how to spot potentially toxic language, Perspective examined hundreds of thousands of comments that had been labeled by human reviewers. Each time Perspective finds new examples of potentially toxic comments, or is provided with corrections from users, it can get better at scoring future comments.
Publishers can choose what they want to do with the information they get from Perspective. For example, a publisher could flag comments for its own moderators to review and decide whether to include them in a conversation. Or a publisher could provide tools to help their community understand the impact of what they are writing—by, for example, letting the commenter see the potential toxicity of their comment as they write it. Publishers could even just allow readers to sort comments by toxicity themselves, making it easier to find great discussions hidden under toxic ones.
We’ve been testing a version of this technology with The New York Times, where an entire team sifts through and moderates each comment before it’s posted—reviewing an average of 11,000 comments every day. That’s a lot of comments. As a result the Times has comments on only about 10 percent of its articles. We’ve worked together to train models that allows Times moderators to sort through comments more quickly, and we’ll work with them to enable comments on more articles every day.
Perspective joins the TensorFlow library and the Cloud Machine Learning Platform as one of many new machine learning resources Google has made available to developers. This technology is still developing. But that’s what’s so great about machine learning—even though the models are complex, they’ll improve over time. When Perspective is in the hands of publishers, it will be exposed to more comments and develop a better understanding of what makes certain comments toxic.
While we improve the technology, we’re also working to expand it. Our first model is designed to spot toxic language, but over the next year we’re keen to partner and deliver new models that work in languages other than English as well as models that can identify other perspectives, such as when comments are unsubstantial or off-topic.
In the long run, Perspective is about more than just improving comments. We hope we can help improve conversations online.
