UIN bets banks pay per engagement outcome: US$2M seed after US$1M run rate
Ex-n1u founders built BehaviorOS, an API that turns app usage into billed outcomes for banks; US$2M seed, 10 clients reaching 80M users.
UIN
What the business is
UIN sells BehaviorOS, an API-based behavioral-engagement platform that banks, wallets, fintechs, retailers and telecoms plug into existing apps to lift recurrence, adoption and retention; it analyzes transactional behavior, fires personalized triggers such as missions and streaks, and bills a monthly fee plus a variable fee per executed outcome.
Starting capital：US$2 million seed announced September 2026, led by Ewa Capital with Driven VC, Brazilian Venture Capital, ADN, GAIN, New Ventures and angels including AngelHub, Ferter, LAN Accelerator and Santiago Siri.
How it started
UIN was gestated in February 2025 in Buenos Aires by Facundo Corsi and Manuel Heredia after n1u, the gamer-focused digital wallet they co-founded that reached about two million users in Argentina, was acquired. Running a fintech taught them that acquiring users was only half the problem; making them come back was the harder, more valuable one, so they set out to sell that capability to other banks and fintechs.
What happened
In under a year UIN reported 10 clients in Argentina, Peru, Ecuador and Mexico, with its technology reaching about 80 million users indirectly and analyzing more than 300 million transactions; it generated over 10 million behavioral triggers a month, improved usage recurrence around 18% and reduced churn about 10% in average implementations. The company passed a US$1 million annualized run rate before the round. In September 2026 it closed a US$2 million seed led by Ewa Capital to grow its commercial and technology teams, deepen products inside existing accounts and push into Mexico, its stated next frontier.
How it ended up
Still running and scaling from its 12-person Buenos Aires base: after the September 2026 seed, UIN's stated target was multiplying its above-US$1 million run rate tenfold within 12 months, mostly by selling more products and use cases into its existing bank and fintech accounts.
Background
UIN's bet is that Latin America's financial institutions no longer have an acquisition problem but an activation and retention one, and that they will pay for engagement per measurable outcome. Founded in February 2025 by Facundo Corsi and Manuel Heredia after their ~2-million-user gamer wallet n1u was acquired, the company sells BehaviorOS, an API layer that studies each user's transactional behavior inside a bank's or fintech's existing app and fires personalized interventions: missions, streaks, incentives and early churn warnings.
The economics follow the thesis. UIN charges a monthly license plus a variable fee per executed trigger, so if its interventions lift card payments, QR transactions or microcredit repayment, the startup shares in that growth. Within a year it reported 10 enterprise clients across Argentina, Peru, Ecuador and Mexico, reaching roughly 80 million users and analyzing more than 300 million transactions, with average implementations improving recurrence about 18% and cutting churn about 10%.
In September 2026 UIN announced a US$2 million seed led by Ewa Capital with Driven VC, Brazilian Venture Capital, ADN, GAIN and New Ventures, plus angels such as Santiago Siri. The company had already passed a US$1 million annualized run rate before its first birthday, and its stated goal was to multiply that tenfold in 12 months, prioritizing Mexico while keeping the team in Buenos Aires.
What has to be true
- The founders validated the pain first-hand: running n1u, a wallet with about two million users, showed that winning installs did not stop churn, which is the problem UIN now sells against.
- Outcome-based pricing converts retention software from a fixed budget cost into a revenue driver, a much easier pitch to conservative CFOs at banks and fintechs.
- A B2B API model lets a 12-person company reach ~80 million end users indirectly through 10 contracts, avoiding the cost of owning a consumer app.
- The disclosed metrics are concrete and recent: over US$1 million in run rate in under a year, about 18% recurrence lift and 10% churn reduction, reported to Forbes Argentina in September 2026.
What can be applied
Know where customers bleed, then sell the cure with outcome pricing: fees tied to results turn engagement from a cost-center buy into a revenue conversation a small team can land regionally.
Aftermath
As of September 4, 2026, UIN was operating from Buenos Aires with about 12 people and 10 enterprise clients across Argentina, Peru, Ecuador and Mexico. It had just closed a US$2 million seed led by Ewa Capital, with the capital earmarked for commercial and product hiring, deeper penetration of existing accounts and expansion in Mexico, which the founders called particularly strategic. The company's public goal was a tenfold increase of its above-US$1 million annualized run rate within the following 12 months.
