HEY BOSTON

We’re working with one of the fastest-growing teams in the Voice AI space, a seed-stage startup transforming how financial services engage customers in high-stakes, mission critical workflows. Already trusted by 6 of the top 15 U.S. mortgage banks, they’ve hit $2M ARR in just 8 months (on track for $3M) and are scaling at 43% month over month since their seed raise last November. With a Series A planned for early 2026, this is a rare opportunity to join a company just before it enters hypergrowth. With a lean team of engineers from Google, Meta, Apple and Stanford, they’re building AI systems that outperform humans in industries like mortgage, insurance and small business lending. Now, they’re looking for two exceptional Founding Engineers to own backend systems, drive product heavy initiatives and shape the technical foundation of a category-defining company.
