Tidemark leads Adaptive's $30M Series B as construction accounting goes agentic

Adaptive's total funding now stands at $57M, and the round will expand its Project Accounting Agents across job costing, AP, billing, WIP, payments, and compliance.

Adaptive, the agentic accounting platform for construction, has raised $30 million in Series B funding. Tidemark led the round, with participation from existing investors Emergence Capital, Andreessen Horowitz, Pathlight, Definition, and 3KVC. The round brings Adaptive's total capital raised to $57 million.

Adaptive's agents pull in project context—including schedules, daily logs, and answers gathered straight from the field—and use it to handle job costing, accounts payable, billing, WIP, payments, and compliance work on behalf of finance teams. The company's pitch is that finance teams can shift from catching up to getting ahead.

The new capital will accelerate the expansion of Adaptive's Project Accounting Agents across those functions. The company also notes that more than 750 construction companies run on Adaptive across 10+ ERP systems.

The round is a notable bet on a narrow but messy corner of finance: construction accounting, where project data lives across job sites, daily logs, and field conversations. By routing that context into agents that do the accounting work, Adaptive is aiming to cover the full back-office loop of a construction project rather than just one slice of it. With Tidemark leading and a roster of existing backers returning, the Series B gives the company room to push its agents deeper into the workflows contractors already run.
