About this role
About RentFlow
RentFlow is tackling a hair-on-fire problem for small and medium businesses across the U.S.: the way their rent is paid each month is fundamentally misaligned with how cash actually comes in.
We’re building the infrastructure layer to fix that.
Today, ~50% of U.S. businesses are late on rent in any given month. The rest face invisible struggles to pay on time, undermining their stability month after month.
The core issue is structural: rent hits as a single fixed lump sum on the 1st, stacked on top of every other major monthly bill, while revenue and other expenses flow in unevenly. This forces healthy businesses into recurring cash-flow stress and is a major driver of business closures.
RentFlow is the first startup to turn fixed business rent into a cash-flow-synced product, underwritten in real time from transaction-level data to prevent issues before they even surface.
This opens up a $20B+ rent-splitting market and creates a natural wedge into an AI CFO layer for businesses and data opportunities we're uniquely positioned to own.
We're seed-stage, live since May 2025, and growing ~3x MoM. We're ramping up partnerships with the leading rent payment platforms in the U.S., fast-growing SMB software companies, and major property players.
Early-Stage Opportunity
We’re hiring our AI/ML lead to own underwriting, cash-flow intelligence, and data insights end-to-end.
This is a foundational role. You’ll design and ship models that make real financial decisions in production, affecting how and when business owners pay rent each month. You’ll work directly with the founders and have meaningful ownership over both technical direction and business outcomes.
What You’ll Do
Model messy, real-world SMB cash flows from transaction-level data
Build and iterate on underwriting & decisioning systems
Leverage LLMs to surface unique insights into business owner behavior and the forces shaping cash flow beneath the surface
Turn raw financial data into clear, natural insights for business owners and their partners
Design signals that balance risk, growth, and user trust in real time
Collaborate closely with founders on product, risk, and roadmap decisions
Shape the long-term architecture of RentFlow’s AI & data stack
You’ll Be a Great Fit If You
Have built and shipped ML or data-driven systems in production
Have worked with LLMs in production and know where to apply them
Are comfortable working with imperfect, noisy financial data
Care about real-world impact
Enjoy high ownership, fast iteration, and ambiguous problem spaces
Want to help define the technical DNA of an early-stage company
Are excited to be an early hire with outsized impact, real equity, and real leverage on product and company direction
Why This Role Is Different
Your models directly control real money and real outcomes
You’ll help define an entirely new category at the intersection of rent, finance, and AI
You’ll work side-by-side with founders
You’ll have meaningful equity and real leverage from day one
If you want to build something with real stakes, real users, and real impact as an early hire, we’d love to talk!
