Founded in 2009 by Marc Andreessen and Ben Horowitz, Andreessen Horowitz (known as "a16z") is a venture capital firm that backs bold entrepreneurs building the future through technology. We are stage agnostic: We invest in seed to late-stage technology companies, across the consumer, enterprise, bio/healthcare, crypto, fintech and games spaces. a16z is defined by respect for the entrepreneur and the entrepreneurial company building process; we know what it’s like to be in the founder’s shoes. The firm is led by general partners, many of whom are former founders/operators, CEOs, or CTOs of successful technology companies, and who have domain expertise ranging from biology to crypto to distributed systems to security to marketplaces to financial services. We aim to connect entrepreneurs, investors, executives, engineers, academics, industry experts, and others in the technology ecosystem. We have built a network of experts including technical and executive talent; top media and marketing resources; Fortune 500/Global 2000 companies; as well as other technology decision makers, influencers, and key opinion leaders. a16z uses this network as part of our commitment to help our portfolio companies grow their business, so our operating teams provide entrepreneurs with access to expertise and insights across the entire spectrum of company building. https://a16z.com/portfolio/ https://a16z.com/podcasts/ https://a16z.com/videos/ http://a16z.com/subscribe See Disclosures: https://a16z.com/disclosures/

We are Uber. The go-getters. The kind of people who are relentless about our mission to help people go anywhere and get anything and earn their way. Movement is what we power. It’s our lifeblood. It runs through our veins. It’s what gets us out of bed each morning. It pushes us to constantly reimagine how we can move better. For you. For all the places you want to go. For all the things you want to get. For all the ways you want to earn. Across the entire world. In real time. At the incredible speed of now. The idea for Uber was born on a snowy night in Paris in 2008, and ever since then our DNA of reimagination and reinvention carries on. We’ve grown into a global platform powering flexible earnings and the movement of people and things in ever expanding ways. We’ve gone from connecting rides on 4 wheels to 2 wheels to 18-wheel freight deliveries. From takeout meals to daily essentials to prescription drugs to just about anything you need at any time and earning your way. From drivers with background checks to real-time verification, safety is a top priority every single day. At Uber, the pursuit of reimagination is never finished, never stops, and is always just beginning.

Chime was created because we believe everyone can unlock financial progress, and we want to develop solutions and services to empower people to succeed. The premise upon which we started Chime is simple: basic banking services should be helpful, transparent, and easy. Our easy-to-use tools and intuitive platforms give members the ability to have more control over their money and to take action toward achieving their financial ambitions. By designing a member-centric banking app with easy-to-understand financial tools, we’re creating a more competitive market with options for everyday Americans. We offer access to accounts with no overdraft fees, provide members the chance to receive their pay up to 2 days early* with direct deposit, help them build credit history, and build financial literacy to hit their goals—among many other things. Since 2012, we’ve grown our team to more than 1300 Chimers across 3 offices. But more than that, we’ve expanded the products and services we offer to our members based on member feedback. And in doing so, we’ve disrupted the banking industry and changed the conversation for everyday people about money on a national level. Chime is a financial technology company, not a bank. Banking services are provided by The Bancorp Bank, N.A. or Stride Bank, N.A., Members FDIC. *Early access to direct deposit funds depends on the timing of the submission of the payment file from the payer. We generally make these funds available on the day the payment file is received, which may be up to 2 days earlier than the scheduled payment date.
