SentiLink is building the future of identity verification in the United States. The existing ways to determine if somebody is who they claim to be are too clunky, ineffective, and expensive, but we believe strongly that the future will be 10x better.

We’ve had tremendous traction and are growing extremely quickly. Already our real-time APIs have helped verify hundreds of millions of identities, beginning with financial services. We’ve recently raised a $70M Series B round, led by Craft Ventures to rapidly scale our best in class products. We’ve earned coverage and awards from CNBC, Bloomberg, Forbes, Business Insider, PYMNTS, American Banker, LendIt, and others. And we’ve even been a part of history—we were the first company to go live with the eCBSV and testified before the United States House of Representatives.

Why join us?

  • We're solving identity verification once and for all by building something that doesn't exist but should: a way for organizations that verify identities to share blacklist and whitelist information with each other.

  • We're working with top-ten US banks (ones that you likely have in your wallet), almost all of the major small business lenders, and many of the leading fintech lenders.

  • We recently t raised a $70M Series B to end identity fraud, led by David Sacks (founding COO at PayPal) and with participation from a16z.

Engineering at SentiLink

Engineering team and processes

There are two main sub-teams: Platform (builds the API, infra, data pipelines, internal and external tools) and Data Science (builds the models, conducts analyses, prioritizes Risk Operations queues).

Technical Challenges

We're answering the question who are you? in real time. It's a simple question in an offline, known social network, but online or with strangers it becomes very challenging and subtle.

Projects you might work on
  • Build a real-time clustering/information retrieval service capable of connecting tens of millions of applications in real-time.

  • Building an external dashboard used by clients for fraud case reviews.

  • Build our callback API to help tell our partners when we learn something new about their previous customers.

Now that we're moving into a much better office I suggested we do No-Window Wednesdays to remember our roots but got some very dirty looks from the team.
