Adaptive raises $30m led by Tidemark, treats construction accounting as a data-collection problem

Adaptive has raised $30m led by Tidemark to build agents that go and collect the job facts sitting in schedules and daily logs. More than 750 contractors already run their project accounting on it.

What happened

Adaptive announced a $30 million Series B on 17 September 2026, led by Tidemark, with existing backers Emergence Capital, Andreessen Horowitz, Pathlight, Definition and 3KVC all participating.
The money goes into expanding Adaptive's Project Accounting Agents across job costing, AP, billing, WIP, payments and compliance, and into hiring on the New York and Boston teams.
More than 750 construction companies already run on the platform, spanning $5 million to $1 billion in annual revenue and sitting on more than 10 different accounting systems.
The product targets the job facts that live outside the ledger: percent complete right now, the cost code a charge belongs to, and what a subcontractor is actually owed this month.

Why it matters

Who has to decide decision At about $40,000 of fresh capital per existing customer, the growth case Adaptive is funding runs through how much each contractor buys, not how many contractors sign.
What it limits constraint One product has to serve a 200-fold revenue range: the agents tuned for a $1bn general contractor's WIP have to differ from the ones a $5m trade contractor will pay for.
Who's exposed exposure Adaptive's workflows terminate in ledgers owned by other vendors. Its roadmap depends on data access granted by the vendors it sits on top of.
What it sets up precedent With over 40 accounting firms already partnered, the buyer Adaptive has to win next is the contractor's bookkeeper. A ledger vendor can court that channel too.

Thirty million dollars against more than 750 customers already on the platform is about $40,000 each, and the $57m Adaptive has raised in total comes to roughly $76,000 per contractor ^[16]^[17].

The pitch rests on a claim about where the hours go. "The hardest part of construction accounting isn't the accounting. It's finding out what's actually happening on the job, and what that means for the numbers," said Matt Calvano, Adaptive's co-founder and chief executive ^[10]. The company says its system pulls data directly from schedules, daily logs and the field itself, then feeds agents that code invoices to the right job, phase and cost code, match them against purchase orders, draft change orders and chase signatures, prepare billings, assemble monthly WIP, and keep lien waivers and vendor insurance current ^[19]^[12].

The agents stop short of the books. According to Adaptive, they never post to the general ledger on their own, and a person reviews every action and provides the approval before it touches the books ^[7]. Jared Westergard, founder of Blackline Financial, an accounting firm that uses the product, said the agents "handle the invoice coding and change order tracking, so our team can focus on the question clients are actually asking" ^[14]. Dave Yuan, Tidemark's founder and managing partner, said Adaptive "doesn't just help construction finance teams do the work, it increasingly does the work itself" ^[11].

Both descriptions sit in the same announcement. Gathering facts and proposing entries takes coordination hours out of a back office; posting them would take out a role. Neither release includes a valuation, revenue or pricing, so there is no way to tell which of those two things contractors are actually buying ^[15].

I would expect the off-ledger data to work as an advantage only while the schedules and the logs are hard to reach. If contractors keep buying two or three of the six workflows and the ingestion settles into a standard connector, the ledger vendors whose systems Adaptive already reads from, QuickBooks, Sage Intacct, Foundation and Acumatica among them, can price the same ingestion as a feature of the ledger ^[6].

What to watch

Whether Adaptive discloses pricing or revenue per customer at its next raise, the only way to separate coordination savings from seat expansion.
Whether any of the more than 10 accounting systems Adaptive reads from ships native schedule and daily-log ingestion of its own.
Whether the customer count or the number of workflows sold per customer grows faster from here.

Construction accounting runs on facts that do not make it into the accounting system: whether a job is 40 or 60 percent complete, how a delayed material package affects the schedule and the cost to complete, which cost code a charge belongs to, and what is actually owed a subcontractor; that information sits in the schedule, the daily logs, an email approving extra work, and the head of the superintendent running the job.

Clarity analysis

How the coverage leans and what the record actually supports. Read the methodology

Perspective Coverage

How much of the coverage speaks to builders, operators and investors. It measures emphasis, not whether the story is right.

Builder

The only technical account of Adaptive comes from Adaptive. Its release says the agents pull project context out of schedules, daily logs and answers gathered from the field, then code invoices to job, phase and cost code, match them against purchase orders, draft change orders and chase signatures, prepare billings, assemble monthly WIP and keep lien waivers and vendor insurance current. The design constraint is the review step: no agent posts to the general ledger on its own, and a person approves each action first. Neither account says which models do the work, how the ten-plus accounting integrations are kept current, or how often the coding comes back wrong. The SaaS News write-up compresses all of it into one phrase, "human-in-the-loop oversight".

Operator

For a construction controller the promise is narrow and concrete: the office stops calling, texting and emailing the field to establish whether a job is 40 or 60 percent complete before the numbers can be closed. Adaptive says more than 750 companies, from $5m to $1bn in revenue, run on it across more than ten accounting systems including QuickBooks, Sage Intacct, Foundation and Acumatica, and that it works with more than 40 accounting firms. One user speaks: Jared Westergard of Blackline Financial, who said the agents handle "the invoice coding and change order tracking." Adaptive hasn't published a close-time figure, an accuracy rate or retention data. Every posting still needs a person's approval.

Investor

$30m led by Tidemark, with Emergence Capital, Andreessen Horowitz, Pathlight, Definition and 3KVC following on, takes Adaptive to $57m raised since founding. Adaptive did not disclose a valuation, revenue or pricing, so the only scale number available is the customer count, against which the new money is roughly $40,000 per company already on the platform and the lifetime total roughly $76,000. Dave Yuan called Adaptive "one of the clearest examples we've found of a System of Action", Tidemark's term for software that does the work instead of recording it. The proceeds go to the agent line-up and to hiring in Boston and New York.
