For a residential contractor, the first estimate is often the last. The process of measuring a blueprint, pricing out lumber and drywall, and calculating labor can take days. Handoff says it can do the job in two hours [Handoff, Unknown].
The Austin-based startup has built an AI-powered platform that promises instant, price-accurate construction estimates, followed by automated project management. The bet is that speed and accuracy are worth at least $149 a month.
The Wedge of Instant Estimates
Handoff’s core product is a generative AI tool that ingests project details and spits out a detailed takeoff. It calculates materials, labor, and line items, then converts the estimate into a client-ready proposal with a toggle [YouTube, Unknown]. The platform also includes a CRM for tracking leads and an AI teammate for scheduling crews and project phases [Handoff, Unknown][CB Insights, Unknown].
The target is clear: residential contractors, remodelers, handymen, and fix-and-flip investors [StartupIntros, Unknown]. The economic pitch is efficiency, reducing errors and freeing up time for more bids and jobs.
Traction and the $6 Billion Pipeline
The company reports it has scaled to over 10,000 monthly active users, facilitating an estimated $6 billion in annualized project volume [Nemetschek Group, Unknown][Y Combinator, Unknown]. A headcount of 35 employees suggests a team built to support this growth [Built In, 2026].
| Round | Amount |
|---|---|
| 2020 Seed | 3 $M |
| 2025 Series A | 5.7 $M |
A Founder’s Second Act
CEO Dmitry Alexin is leading this push. He is a repeat founder, having previously been CEO and co-founder of 1build, a construction estimating platform that went through Y Combinator’s W20 batch [LinkedIn, 2024]. Before that, he was an early employee on the machine learning team at CloudKitchens [Y Combinator, Unknown]. He holds an MBA from Harvard Business School [LinkedIn, 2026].
Navigating a Crowded Field
The construction software space is not empty. Handoff lists nearly a dozen competitors, from project management staples like Buildertrend and Jobber to estimating specialists like Buildxact [Competitors]. The risk is that Handoff becomes another feature in a crowded dashboard, rather than the central operating system for a contractor.
Its recent $5.7 million Series A, closed in June 2025, provides runway to prove this integration thesis [Commercial Observer, June 2025][PitchBook, June 2025]. The participation of strategic investors like building materials giant Masco and proptech software leader Nemetschek Group suggests industry validation beyond pure venture capital.
The Next Twelve Months
The immediate roadmap includes launching an Android app, broadening access for crews in the field [Handoff, July 2025]. The larger challenge is moving from a tool for estimates to the default platform for running a residential construction business. Success will be measured by retention and expansion within its 10,000-user base, and by the conversion of that $6 billion project pipeline into recurring, high-margin SaaS revenue.
