Today we're announcing two things at once: a new name, Onshore, and a $31 million Series B led by FPV Ventures, with participation from Vertex Ventures, Restive Ventures, PruVen, and Y Combinator.
The name is the more important of the two. Tax shouldn't feel abstract or outsourced. It should be grounded in evidence and accountable to outcomes. That's what “Onshore” means to us: the work stays close, the reasoning stays visible, and a real person is accountable for every number we put on a return.
Over the past decade, almost every part of a company got a modern platform. Sales runs on a CRM. HR runs on software built for it. Engineering ships continuously. Tax didn't. It's still dominated by the traditional accounting-firm model: billable hours, fragmented data, and an answer that arrives months after the work is done.
The cost of that gap is enormous. More than $200 billion in tax incentives go unclaimed every year, not because companies aren't eligible, but because the system makes claiming them slow, expensive, and uncertain.
Onshore is an AI-native platform that replaces manual CPA workflows with continuous, automated tax intelligence. Our agents read your data against the full tax code, and credentialed tax professionals review and defend every figure before anything is filed.
The result is speed that used to be impossible. A traditional R&D credit study takes around 270 days. Ours takes 28, with the same documentation standard behind it, so it holds up if a question ever comes.
So far, more than 500 companies have used Onshore to identify and defend over $600 million in incentives.
This round lets us go beyond credits and incentives into the rest of the tax function: the recurring, high-stakes workflows that still run on spreadsheets and billable hours. We're grateful to our investors, and more than anyone, to the operators and farmers who trusted an early version of this with their returns.
If your business does technical work on a farm, a shop floor, a job site, or a rig, there's a good chance you've already earned something in the tax code. We'd like to find it.
