Top Tech Startups in California, US in 2027

Our mission is to reinvent the way people learn, starting with language. Learning a language can change a life by opening doors to new cultures, careers, and communities. Two billion people around the world are actively trying to learn a language, but the best way to learn (one-on-one tutoring) is hard to access at scale and hasn’t been meaningfully improved in decades. Speak is building a human-level, AI-powered tutor in your pocket: a conversation-first experience that lets learners actually speak, get instant feedback, and progress through carefully designed lessons. The result is a complete path from beginner to confident speaker across multiple languages. Speak first launched in South Korea in 2019, where Speak has now become the number one language learning app, and we now serve learners across many markets and 15+ languages. Speak is one of the world’s leading AI companies, with over $150m raised in venture investment from OpenAI, Accel, Founders Fund, Khosla Ventures, and more, with a distributed team across San Francisco, Seoul, Tokyo, Taipei, and Ljubljana.

We are solving a huge problem in financial services that has been lying unsolved for decades. All major payment systems (including wallets ) require two sided onboarding i.e. Payor and Payee need to onboard before they can transact. We have built a way to generate and transmit Digital Payments without onboarding the Payee/Recipient. This is huge in terms of bringing traditional paper and cash payments online. Add to that, we've figured out a clever way to monetize from both sides thereby changing the financial equation from Customers paying us to us paying our customers cash back from card fees! Our investors, whom we call our "believers," include Tim Draper, Adam Draper (Tim Draper's family), Naval Ravikabt through his AngelList Maiden Fund, co-founder of Intuit and more! Institutional investors include a top 4 bank and top 5 insurance company. Checkbook lets businesses move away from paper to deliver Digital Checks directly to a recipients email. This allows businesses to keep all their existing Accounts Payable (or Accounts Receivable processes) in place while moving to a completely online solution. All you need to send a check is the name and email of the recipient along with the amount you are sending. Recipients do not need to sign up for any service, download any app or pay any fees to receive payments. Digital Checks can be deposited and cashed online after instantly verifying banking credentials. No more paying high % based transaction fees on credit and debit cards or sharing sensitive bank account and routing numbers to payor.
