Kapital Builds SMB Finance OS

Kapital is positioning the card as a feature, not the business. In LatAm, card interchange is only about 0.5% to 0.9%, so a company that only sees card swipes sees a thin slice of spend and has limited room to monetize. Kapital instead pulls in bank account activity, e-invoices, bill pay, lending, and cash flow data, then sells software and credit against that fuller picture.

• The product logic starts with what finance teams actually need to run day to day. A card mainly captures employee purchases, but AP, supplier payments, collections, and payroll sit outside that stream. Kapital built around the company ledger, using Mexico's e-invoicing rails to monitor the broader flow of money.

• That creates a different revenue mix than Brex style card first fintechs. Kapital chose subscriptions of about $40 per month for its dashboard and high margin lending, because lending can carry 50% to 70% margins across LatAm while card interchange is structurally weaker than in the U.S.

• The comparison with Nubank also shows the market split. Nubank is a broad consumer bank that expanded into business banking, while Kapital is built around SMB operations. By 2024, Kapital had expanded from banking and cards into FP&A, AP and AR, treasury, and loans, with deposits rising from $241M in Q1 2024 to $569M in Q4 2024.

The next phase is deeper control of the SMB back office. As Kapital adds payroll, contractor payments, treasury, and cross border money movement, the company gets closer to becoming the operating system for how LatAm businesses move cash, borrow, and manage risk, which is a much larger and stickier position than owning the card alone.
