Stark Bank的API银行押注：2022年获贝佐斯支持，到2025年处理资金达6000亿雷亚尔
拉斐尔·斯塔克押注企业会通过API而非分行进行银行交易；在获得贝佐斯支持的4500万美元融资后，Stark Bank在2025年处理了6000亿雷亚尔。
Stark Bank
做的是什么生意
An API-first digital bank for mid-size and large Brazilian companies: corporate accounts, Pix, payments, payroll, corporate debit and credit cards and accounts payable/receivable automation, plus Stark Infra, a unit selling its banking technology to third parties.
启动资金：Bootstrapped with nearly R$1M from founder's previous startup, then $500K from angels and a $2M seed
起因
Rafael Stark, an ITA-trained engineer who had built Android apps and founded Hummingbird after returning to Brazil in 2014, started Stark Bank in August 2018 with money from that earlier company. His trigger was a developer's gap: he was used to integrating Google Maps and Twitter APIs, yet found no bank in Brazil offered one - and he called the incumbent payments system archaic. He piloted an API for transfers and, by 2019, was handling nearly every transactional part of banking through APIs.
经过
Stark Bank obtained a direct credit corporation (SCD) licence in October 2020 - which the company called a first for a seed-stage fintech - and raised a $13M Series A in December 2021 led by Lachy Groom, with founders of Coinbase, Dropbox, Flexport, Figma, Rappi, dLocal, Wildlife and Slack participating. Four months later, in April 2022, Ribbit Capital led a $45M Series B joined by Bezos Expeditions - the Amazon founder's first investment in Brazil - plus SEA Capital, K5 Global and founders of Airbnb and Kavak, leaving Stark Bank with $58M in cash. It served more than 300 'new economy' clients such as Loft, Buser, Daki, Cora and Bitso, had already broken even, and was moving into corporate credit.
结果
The model kept compounding: Stark Bank said in February 2024 that it processed R$155B (about $27B) in payments during 2023 - a threefold jump - while net income more than doubled to R$71.5M, and by March 2025 it served roughly 800 clients, including 52 crypto-focused firms. It transacted about R$600B in 2025 and set a R$1T target for 2026, counting Ambev and iFood among clients. As of April 2026 it was still scaling: a full Brazilian bank licence filed in December 2023 remained pending, a licence abroad was sought for 2027 operations, and an IPO in the United States was planned on a five-to-ten-year horizon.
背景
Stark Bank由拉斐尔·斯塔克于2018年8月创立，他是ITA培养的工程师，2014年从美国返回并创办了数字产品公司Hummingbird。作为开发者处理银行数据时，他发现巴西没有一家银行提供API——集成都是手工完成——他利用Hummingbird的收益，投入近100万雷亚尔创办了Stark Bank，打造他所说的面向公司的未来银行。
切入点是一个开发者产品：一个用于转账和退款的API，Buser是首批客户之一，用于付款自动化。到2019年，Stark Bank通过API处理了几乎所有的交易银行服务，增加了网上银行以及与Excel和Google Sheets的集成来处理工资单，到2020年获得了直接信贷公司牌照，公司称这在种子期金融科技中属首创。其愿景集中于服务中大型公司，它们需要控制——谁批准付款、适用何种限额——而非消费者便利。
资本验证了这一论点：2021年12月由Lachy Groom领投的1300万美元A轮融资，参与者包括Coinbase、Dropbox、Flexport、Figma、Rappi、dLocal、Wildlife和Slack的创始人；紧接在2022年4月，Ribbit Capital领投4500万美元B轮，贝佐斯探险队参投——杰夫·贝佐斯在巴西的首笔投资——另外还有SEA Capital、K5 Global以及Airbnb和Kavak的创始人。拥有5800万美元现金和300多家客户（如Loft、Buser、Daki、Cora和Bitso），公司已经实现盈亏平衡。
到2024年2月，Stark Bank表示在2023年处理了1550亿雷亚尔（约270亿美元）的支付，较上年增长两倍，净利润超过一倍，达到7150万雷亚尔，服务约600家客户；到2025年3月，客户约800家，包括52家加密货币公司；2025年处理了约6000亿雷亚尔，目标在2026年达到1万亿雷亚尔。截至2026年4月，客户包括Ambev和iFood，公司正在寻求巴西和国外的银行全牌照，计划推出AI银行助手，并计划在五到十年内进行美国IPO。
这件事要成立，得有什么
- 切入点匹配了真正未被满足的需求：巴西开发者和财务团队无法通过API自动化支付、退款和工资，所以早期客户自己也推动了产品路线图。
- 它瞄准公司而非消费者，押注控制功能——审批规则、按类别支出限额、审计跟踪——在B2B银行中会胜过便利性。
- 在大型融资前就实现盈利：早期盈亏平衡使Stark Bank得以靠自身数字扩张，并吸引像贝佐斯探险队这样的投资者，并无被迫的增长叙事。
- 央行的开放金融和Pix指令将监管转化为顺风：API原生基础设施成为接入巴西实时支付系统的合规方式。
可借鉴之处
销售客户已认可的集成：Stark将一个开发者的API痛点转化为工资和卡片，随后遵循客户需求成为一家全面银行，并在扩张前保持盈利。
后续进展
截至2026年4月8日，Stark Bank是一家盈利的、私有的巴西企业数字银行，2025年处理了约6000亿雷亚尔，并目标在2026年达到1万亿雷亚尔。其约800家企业客户包括Ambev和iFood。创始人拉斐尔·斯塔克告诉CNN巴西频道，其巴西银行全牌照（2023年12月提交）仍在等待，已在海外申请，计划2027年开始运营，并且资金充足，无需再进行融资；美国IPO预计在五到十年内进行。
