Agave’s $15M Series A Brings Spencer Rascoff Into Construction AI

Agave raised a $15 million Series A on July 7, 2026, to apply AI to construction financials, per the July 7 venture funding roundup. Accel led the round, with Y Combinator Continuity, Khosla Ventures, and Zillow founder Spencer Rascoff participating. The San Francisco company is profitable, has tripled its revenue year over year, and works with more than 500 contractors.

Rascoff has spent two decades on the property-data layer aimed at consumers. His first construction check is a small bet on the back-office stack that sits below it. Agave was founded in late 2021, and the $15M round is the team’s first priced test at scale.

A Zillow Founder’s Quiet Bet on Construction Back-Office AI

Rascoff has joined a $15 million Series A in Agave, a San Francisco company that uses AI to handle back-office paperwork for construction firms. The round, announced Tuesday, was led by Accel and also drew Y Combinator Continuity, Khosla Ventures, and Rascoff personally. Rascoff’s path from Zillow to a back-office AI startup is unusual: Zillow built a public property-data layer aimed at consumers, while construction runs on private data inside contractor accounting systems that rarely talk to each other. The same founders wrote, in their seed-round post, that no equivalent of Plaid, the bank-data integrator, has been built for construction, and the Series A is the first priced round to fund that build at scale.

Agave’s pitch is that the same connector play that worked for residential real estate can work for general contractors, subcontractors, and the suppliers they pay. The round is also Accel’s second consecutive lead, after the seed, and the first institutional round Khosla and YC Continuity have priced into Agave’s cap table. Reno, Zucchi, and Azimi met at Graphiq in 2014, then worked together inside Amazon after Amazon acquired Graphiq, before leaving to start Agave in 2021.

What the $15M Round Actually Buys

Agave announced the $15M Series A in a release that doubled as a status report, per Agave’s $15M Series A and customer roster. The company is profitable, has more than tripled its revenue year over year, and now serves more than 500 general and specialty contractors ranging from $5 million to more than $5 billion in annual revenue. Its tools sit on top of more than 14 enterprise resource planning and project management platforms, including Procore and Autodesk Build, and the company has spent four years building the two-way connections that let AI agents work across them. The new capital is going to team growth and product expansion, with founder Tom Reno, also the chief executive, leading the next phase. Accel led the round after leading the seed, and Y Combinator Continuity, Khosla Ventures, and Rascoff added to a total raised of more than $20 million since Agave was founded in late 2021.

• Year founded: Late 2021, by Tom Reno, John Zucchi, and Pooria Azimi
• Revenue trajectory: Tripled year over year, profitable for more than two years
• Customer count: More than 500 general and specialty contractors
• Time savings: Customers report more than 60 hours saved per month, and Agave reports more than 80% time savings on thousands of administrative tasks
• Integrations: 14+ ERP and project management systems, including Procore and Autodesk Build

Customers report saving more than 60 hours per month on tasks such as data entry, financial reporting, and cost reconciliation across systems, and Agave’s own data point is a more than 80 percent time savings on thousands of monthly administrative tasks. The customer list includes Evans General Contractors, Stacy Witbeck, Brinkman Construction, Satterfield & Pontikes, and RW Dake, names that span commercial, civil, and residential work.

Agave is profitable, has been for more than two years, and the contractors it serves run from $5M in annual revenue to more than $5B. It is, by contrast, a small check against the size of the addressable market: more than $100 billion in tracked project volume is a fraction of US construction, and Agave is one of a small group of AI-first entrants chasing the same contractors. The founders are Tom Reno, John Zucchi, and Pooria Azimi, with Reno continuing as chief executive. Reno, Zucchi, and Azimi met at Graphiq in 2014, then worked together inside Amazon after Amazon acquired Graphiq, before leaving to start Agave in 2021.

The Messy Paperwork Most Software Avoids

Construction financial work is hard to automate for a reason. Projects span years, change scope mid-stream, and involve multiple companies paying each other in stages tracked by job, phase, and cost code. The result is a paperwork load that resists the off-the-shelf data-integration play that worked in banking.

Most of the work lives in PDFs, spreadsheets, and email threads, with lien waivers, change orders, and payment applications bouncing between general contractors, subcontractors, and suppliers. Each project is its own profit center, with costs tracked at a granularity that general-purpose accounting tools do not understand. The risk of a missed change order, a duplicate invoice, or a vendor whose insurance has lapsed is the kind of error contractors describe in their own words. Agave’s pitch is that AI agents, sitting on top of the systems contractors already use, can catch those errors alongside the routine reconciliation work.

The market has been hard to crack for a reason: the construction software stack runs from Procore to Autodesk Build to more than a dozen ERP platforms, and any new tool that requires contractors to migrate data is a hard sell. Agave’s approach is different: the company works on top of those systems, adding AI agents without forcing migrations, and the founders wrote in their seed-round post that the integration work was the part of the build most teams had skipped.

The pitch to investors leans on three numbers. The first is 500-plus contractors using the platform, including Evans General Contractors, Stacy Witbeck, Brinkman Construction, Satterfield & Pontikes, and RW Dake. The second is $100 billion in tracked project volume across more than 80,000 projects. The third is 14-plus ERP and project management systems Agave has spent four years wiring into a two-way connection, with customers reporting more than 60 hours saved per month on data entry, financial reporting, and cost reconciliation.

Layering AI on Top of the Construction Stack

Agave’s product is a thin layer between contractors and the systems they already pay for. The platform reads from ERPs and writes back to project management systems, including Procore and Autodesk Build, with two-way connections to more than a dozen other tools. That lets AI agents do reconciliation, invoice coding, vendor compliance, and other back-office work without forcing a contractor to migrate data.

• Invoice coding: matching credit card and AP transactions to the right job and cost code
• Cost reconciliation: tying purchase orders to invoices and surfacing mismatches
• Vendor compliance: checking insurance certificates against contract terms
• Per-project-manager financials: turning one master job report into tailored reports for each PM
• Custom AI agents: workflows pre-built tools do not cover

The integrations are the moat, and the moat took four years to build. Agave has spent that time wiring one-off connections to construction software, much of it on-prem and built without APIs, and selling access to other construction-tech startups. The shift from API-for-others to AI-for-contractors happened after founders Tom Reno, John Zucchi, and Pooria Azimi ran 300-plus interviews with superintendents, foremen, controllers, and software providers, per the seed-round post. The product is now organized around workflows contractors already do, with custom AI agents for the work pre-built tools cannot cover.

The work that gets automated is unglamorous and the kind of thing most enterprise software never touches. AI agents check vendor insurance documents against contract requirements, code credit card transactions, reconcile invoices against purchase orders, and turn one master job report into per-project-manager financials. The customers the press release names are the ones running the workflows Agave says the product replaces.

Accel and Khosla’s Vertical AI Wager

Accel has now led both of Agave’s priced rounds, the seed and the Series A. Khosla Ventures anchored the same-day Norm AI legal-AI round at a $1.2 billion valuation, one of the larger vertical-AI raises announced the same week. Y Combinator Continuity, the growth-stage arm of the accelerator, also participated, as did Rascoff, a path other YC-backed AI accounting startups in Europe, like Finto’s Y Combinator-backed accounting bet, have walked in their own verticals. The same day’s funding roundup flagged the pattern: capital is moving into real-world infrastructure and domain-specific AI in sectors like construction, defense, and legal.

Agave sits inside a wave of vertical-AI raises that includes Norm AI at $120 million, Monogram at a $40 million seed, and Taktile at a $110 million Series C, all announced the same week per the same roundup. The deal sizes are uneven, but the pattern is consistent: investors are funding vertical AI software that augments legacy systems, in sectors from construction to defense to legal.

Vertical AI is not new, and the graveyard of construction-tech startups is long. Agave’s traction could prove durable, or it could become a one-product story that gets cloned by an incumbent once the integrations are reverse-engineered. The moat today is the 14-plus ERP connections and the 500-contractor reference base, both of which a competitor would need years to replicate. The Series A funds the next phase, and the founders are still running the company they started in 2021.

Most energy in AI goes into building new software. The bigger opportunity is deploying AI to operate on systems companies already depend on.

Vas Natarajan, a partner at Accel, made the comments in Agave’s July 7 announcement.

The bet Accel is doubling down on is straightforward: contractors want AI to make their existing systems work better. Agave has 14-plus ERP connections and a 500-contractor base, neither of which falls into place overnight. Construction is one of the largest software stacks in the US economy, and one of the slowest to digitize, and Agave’s footprint now touches more than $100 billion in project volume.

What the Series A Doesn’t Answer

The Series A also leaves open the harder questions. Agave is one of a small group of AI-first construction software companies chasing the same contractors, and the $15M does not, on its own, separate the company from the field. The construction software graveyard is real, with failure modes that are familiar: high customer acquisition cost, slow product expansion across trades, and incumbents who eventually copy the workflow and offer it as a feature. Ken Pattridge, the chief financial officer of RW Dake Construction, said in the press release that his team would not be able to keep up without Agave.

The investor list cuts both ways. Accel’s repeat lead signals conviction, and the same investors have also backed construction-tech entrants that did not make it. The Y Combinator Continuity participation and Rascoff’s involvement are notable lines on the cap table, and the size of the round is the size: $15M is enough to expand the product, though it is small against the addressable market. Natarajan, the Accel partner, said in the press release that Agave is ‘a rare combination of experienced team and market need’ and that the founders are ‘the ones to capitalize on the opportunity.’
