AI operating system for commercial loans. Backed by Y Combinator.
About the role
You’ll be working alongside founders who’ve led fintechs to Series D and shipped at scale on agent infrastructure problems most teams haven’t earned the chance to solve yet — self-evolving & self-healing agents, software factory, and large scale evals. If we get this right, millions of businesses currently ignored by banks get access to the credit they should already have and we’ll be building the most powerful tool banks have seen.
What they're looking for
- You deeply understand the importance of security, reliability, and auditability of shipping AI agents for banks, fintechs, and regulated financial institutions
- You are constantly up to date with frontier agentic architecture, techniques, harnesses, and self-evolving infrastructure
- You have a strong desire to own a product end to end: building it, deploying it, talking to customers, selling it, learning from it
- You can hold your own with a 60-year-old banker — curious, respectful, and genuinely interested in what they know
- You're comfortable with change. Early stage means rolling up your sleeves and staying flexible as the company, product, and priorities evolve. Learn and unlearn

Banks are running on bloated operations teams, losing deals and working with antiquated software that works half the time.
We're building autonomous lending agents that fix this — the infrastructure for how commercial credit gets issued, and how our economy grows.
Proximitty (YC W26) is building autonomous commercial lending teams for the largest banks and fintechs in the US. We're backed by top investors — Y Combinator, CRV, Cohen Circle, and Uphonest, with angels leading teams at Stripe and OpenAI. We’re growing rapidly and on track to hit 7-fig ARR by end of year.
