SentiLink provides innovative identity and risk solutions, empowering institutions and individuals to transaction with confidence. We’re building the future of identity verification in the United States replacing a clunky, ineffective, and expensive status quo with solutions that are 10x faster, smarter, and more accurate. We’ve seen tremendous traction and are growing extremely quickly. Our real-time APIs have helped verify hundreds of millions of identities, starting with financial services and rapidly expanding into new markets. SentiLink is backed by world-class investors including Craft Ventures, Andreessen Horowitz, NYCA, and Max Levchin. We’ve earned recognition from TechCrunch, CNBC, Bloomberg, Forbes, Business Insider, PYMNTS, American Banker, LendIt, and have been named to the Forbes Fintech 50 list every year since 2023. Last but not least, we’ve even made history - we were the first company to go live with the eCBSV and testified before the United States House of Representatives on the future of identity. SentiLink supports a variety of ways to work, ranging from fully remote to in-office. We operate as a digital-first company with strong collaboration across the U.S. and India. We maintain physical offices in Austin, San Francisco, New York City, Seattle, Los Angeles, and Chicago in the U.S., and in Gurugram (Delhi) and Bengaluru in India. If you’re located near one of these offices, we would love for you to spend time in the office regularly. Some roles are hybrid or in-office by design. For example, our engineering team in India works primarily from our Gurugram office.

We want to encourage employees to adopt better cybersecurity practices in a way that's actually effective, and entertaining enough that the training doesn't feel like work. Think Duolingo, but for cybersecurity. We created a platform to roll out a cybersecurity awareness program quickly and easily by sending short conversations of just 3-4 minutes. The platform also simulates phishing attacks to prepare employees to face hackers in a safe environment. Created in 2020, Riot has raised $45m with leading investors (Y Combinator, Left Lane, Base10, Funders Club and Frst Capital) and is now protecting more than 2 millions employees in over 2,000 companies (including Intercom, Deel, and Deezer) all over the world. Cybersecurity impacts everyone, every day, and is now the number one risk to any organization, from small businesses to big firms. And yet, in most companies the cybersecurity culture is non-existent. Hackers know this, and they're taking advantage by targeting the weakest link: employees. We're on a mission to fix that for good.
