Z1's teen-banking bet: 30%/week growth and $22M raised, then absorbed by rival NG.Cash

Z1 was a digital bank app for Brazilian and Latin American teenagers and young adults: a fee-free account, a linked prepaid card, Pix cash-out and savings features, monetized later through premium subscriptions (Z1 Pass) rather than parent-controlled allowances.

Gen Z Brazilians would adopt a dedicated teen bank with prepaid card and Pix, build loyalty early and stay for life — a segment incumbents ignored.

~$22M total: YC W21 ($125K); Maya Capital-led $700K seed (Mar 2020); $2.5M Homebrew-led round (Jul 2021, with The Chainsmokers' Mantis, Clocktower, Goodwater); $10M Kaszek-led Series A (Nov 2021); $9M 2023 round (Homebrew, Parade Ventures, Kindred Ventures).

João Pedro Thompson and Thiago Achatz, entrepreneurs-in-residence at Maya Capital, started Z1 in late 2019, with Mateus Craveiro and Sophie Secaf joining as co-founders. The thesis: Gen Z is roughly 30% of Brazil, grew up through recessions, starts earning early, and would switch to a bank that treats them as customers rather than children. YC W21 and a $700K seed led by Maya Capital followed.

In July 2021 Z1 raised $2.5M led by Homebrew. Six months later, Kaszek led a $10M Series A: revenue had grown 26x (~40%/month) and customers 8x (~30%/month); Z1 made its core banking free after charging $2/month, and cited Brazil's Pix instant-payments launch (105M registered users) as the enabler. A $9M round in 2023 (Homebrew, Parade Ventures, Kindred Ventures) was extended into 2024 — a smaller round from existing investors — as Nubank and other incumbents moved into teen accounts.

Gone as a standalone: negotiations with rival NG.Cash began in December 2024, and on February 13, 2025 NG.Cash absorbed Z1's customer base, taking the combined platform past 6M clients and ahead of Nubank for under-18 accounts. Z1 ceased to exist as a brand; founder João Pedro Thompson said Z1 considered raising again in 2025 but chose the deal, and the founders did not join NG.Cash.

Z1 bet that Gen Z would choose a dedicated teen bank, not a parent-controlled app, and stay for life — a loyalty play incumbents could not copy overnight.

The wedge worked early: 30%/week growth and 26x revenue in six months proved teens wanted prepaid cards, Pix and fee-free accounts.

The moat didn't hold: Nubank and rivals moved into teen accounts, and a $9M 2023 round plus a 2024 extension showed investors were no longer paying up for the segment.

The rational ending: instead of a down round, Z1 merged its base into NG.Cash in February 2025 — 6M+ combined clients, ahead of Nubank for under-18 — and wound down the brand.

A wedge can be real and still lose: teen banking proved demand, but when Nubank and rivals added teen products, the pure-play couldn't raise — the exit was handing its base to a competitor.

As of February 17, 2025, Z1 no longer exists as a standalone: its customer base was integrated into NG.Cash on February 13, 2025, taking the combined platform past 6M clients and ahead of Nubank for under-18 accounts. Founder João Pedro Thompson said Z1 considered raising again in 2025 but chose the NG.Cash deal; the founders did not join NG.Cash, which continued as the main brand with an AI WhatsApp assistant, a prepaid card and savings at 100% of the CDI. Users migrated without extra costs; Z1's ~$22M of venture funding ended in absorption rather than a shutdown or a sale.
