WHY INTERFACE.AI

Series A

• $30M raised
• Cash-flow positive — we’re not burning cash hoping the product works. It works. Customers are live, revenue is real, and the mission — bringing intelligent financial services to everyday Americans — is one you can explain to your family without a slide deck.

You’ll work directly with Bruce Kim (Co-Founder) and Srinivas Njay (CEO) — founders who understand engineering deeply and give their VP the authority and trust to actually run the global function. We offer top-of-market base, significant early-stage equity, comprehensive benefits, and a modern SF office that’s worth showing up to.

The team we’re building is small enough that your judgment shapes everything. The market we’re in is large enough that what you build will matter for a long time.
