Adaptive Raises $30M for Construction Accounting AI

Before a contractor can trust the month-end numbers, somebody has to reconstruct the month. The ledger knows what was entered. The jobsite knows why the cost moved, whether the schedule slipped, which change order is waiting, and how much work is actually complete.

Adaptive has raised a $30M Series B led by Tidemark to bring those two records closer together. The September 17, 2026 financing includes returning investors Emergence Capital, Andreessen Horowitz, Pathlight, Definition, and 3KVC, and Adaptive says it brings total capital raised to $57M. The company will use the round to expand its Project Accounting Agents and grow teams in New York and Boston.

The larger bet is that construction finance needs more than another database. Adaptive is building agents that gather project context from schedules, daily logs, project-management systems, email, text, voice, and people in the field, then prepare accounting work for human review. That review boundary matters because the product touches job cost, billing, WIP, payments, and the records contractors use to decide whether a project is making money.

What Adaptive Announced

The $30M Series B was led by Tidemark. Existing investors Emergence Capital, Andreessen Horowitz, Pathlight, Definition, and 3KVC also participated. Adaptive did not disclose its valuation, ownership changes, round terms, or any board changes.

Adaptive reports that more than 750 construction companies use the platform across more than 10 accounting systems, and that the company works with over 40 accounting firms. Its customers range from businesses with $5M in annual revenue to operators at $1B, including general contractors, specialty trades, and real-estate developers. These figures come from Adaptive’s announcement and have not been independently audited.

Why the Field-to-Books Handoff Matters

Construction accounting depends on facts that often appear outside the general ledger. A controller can see an invoice but still need a project manager to explain the cost code, a superintendent to estimate percent complete, or a vendor to return documentation before payment. When that context arrives late, the accounting system can be internally consistent while the project view is already stale.

Adaptive is designed around that coordination gap. Its agents can pull information from project-management and financial systems, then reach people through voice, text, or email when the answer is not already recorded. The company says the software prepares work but does not post autonomously to the general ledger; a person reviews each action and supplies the accounting judgment and approval.

From Financial Software to Project Accounting Agents

Adaptive’s product started with construction financial workflows and has expanded into named agent roles across job costing, accounts payable, billings, WIP, forecasting, change orders, lien waivers, insurance, payments, and compliance. The platform works alongside systems such as QuickBooks, Sage, Foundation, Acumatica, and Procore instead of requiring an ERP replacement.

That positioning explains Tidemark’s investment thesis. The firm describes Adaptive as a “System of Action,” software that operates across existing systems of record and does the coordination work required to move a process forward. The commercial question is whether Adaptive can turn that cross-system context into dependable labor capacity without weakening the controls finance teams need.

The Founders and Adaptive’s Capital Path

Matt Calvano, Henry Bradlow, and Francisco Enriquez began building Adaptive after an earlier real-estate idea exposed the bookkeeping and project-finance problems facing contractors. Calvano now serves as co-founder and CEO, while Bradlow is co-founder and CTO. Current first-party evidence did not establish Enriquez’s operating title with enough confidence, so he is identified here as a co-founder.

Adaptive’s publicly disclosed financing history includes a $750K pre-seed in 2021, a $6.5M seed led by Andreessen Horowitz in 2022, and a $19M Series A led by Emergence in 2024. Historical company materials rounded the prior total to $26M or reported $26.4M, while the new announcement reports $57M after the Series B. The current company total is the most authoritative figure, but the disclosed round history does not support forcing a more precise reconciliation.

The Market Around Construction Finance AI

Adaptive is arriving at a moment when construction companies are spending more attention on connected data, margin protection, and AI-assisted work. Deloitte’s 2026 Engineering and Construction Industry Outlook describes firms confronting cost pressure and labor constraints while adopting digital tools for estimation, risk management, scheduling, and faster operating decisions.

The competitive field is broader than accounting software. ERP providers, project-management platforms, payments products, specialist automation vendors, and accounting firms all touch pieces of the same workflow. Adaptive’s opportunity sits in the connective work between those systems, but that also creates integration, data-quality, implementation, and trust burdens that a narrower point solution can avoid.

What the $30M Has to Prove

The Series B gives Adaptive room to extend its agents across more financial workflows and more complex contractors. It also raises the standard for evidence. The company will need to show that its agents can preserve approval controls, handle exceptions across different accounting stacks, and produce repeatable outcomes beyond the customer examples selected for the announcement.

Construction projects change faster than month-end reporting cycles. Adaptive is betting that software can collect the story of the job while it is still happening, prepare the financial work that story requires, and give the people responsible for the books a better answer before a stale number becomes a margin surprise.
