The autonomous tax firm — transfer pricing and cross-border tax compliance for global companies
HQ: London, UK | Founded: 2024 | Employees: 17 | Stage: Seed | Website: https://usecaribou.com
Caribou is the first autonomous tax firm, providing a full-stack transfer pricing and cross-border tax compliance platform for multi-entity companies. The platform uses AI to graph a company's entire global structure — every entity, process, and employee — into a model called the Atlas. From there, Caribou handles transfer pricing policy design, intragroup agreement drafting, benchmarking analysis, accounting journals, and ongoing compliance monitoring. It also covers VAT, permanent establishment risks, and R&D credits. The company serves fast-growing global businesses including Butternut Box, OpenFX, Encord, Vertice, Omnea, and Hadrian, claiming to save them hundreds of thousands on legal fees and surprise tax bills. Founded in 2018 as Rebank (a banking workflow platform) by Juan Andrade (CEO) and Simon White (CTO). Rebank was accepted into Y Combinator Winter 2019 batch and raised a $2.78M seed round from ADV, Y Combinator, Oriza Ventures, and Jude Gomila. After building Rebank, the team realized that companies going global faced a deeper pain point with cross-border tax compliance, leading to a pivot to Caribou in 2024. In May 2026, Caribou raised a further $2.7M seed round from Blue Wire Capital, Y Combinator, Tiny Supercomputer Investment Company, and Venture Together. ~17 employees based in London, UK.
Caribou (pivot from Rebank YC W19) is an ambitious play on a very gritty problem: transfer pricing for global companies. The insight is powerful — every startup that goes global inherits a tax/legal mess that compounds with every hire and invoice. The traditional solution involves Big Four firms charging millions, or piecing together law firms in each country. Caribou's 'autonomous tax firm' model uses AI to replace what currently takes consultants months. The founding team has persistence (rejected by YC once, got in on second try) and domain evolution (from banking to tax). Two seed rounds totaling $5.5M with notable investors. Key risk: transfer pricing is a complex, high-stakes compliance area where errors can be very expensive; building trust with finance teams is hard.
