Nitra builds AI-native financial infrastructure for independent medical practices, combining spend management, lending, and a Visa card in one product. Independent physicians occupy an awkward position in financial services: their practices carry real revenue and predictable insurance receivables, but they are small, highly regulated, and buy through specialised supply channels, so generic business banking fits poorly. Nitra designs for that specificity, handling the vendors, procurement categories, and reimbursement cycles that a dermatology or dental practice actually runs on.

Understanding those cash flows is what makes the credit product work. Insurance receivables are more predictable than most small-business revenue, which supports underwriting that generalist lenders cannot price, while spend controls and expense categorisation keep the product in daily use. Backed since 2022 and funded through a 50 million dollar Series B in 2026, Nitra reflects a recurring pattern in the portfolio: vertical fintech where domain knowledge, not distribution spend, is the defensible asset. Every practice added strengthens the supplier and reimbursement data that makes the next credit decision more accurate.
