San Francisco – September 30, 2026 -- Miter, an AI-powered workforce management platform for the construction industry, has raised a $40 million Series B round led by Battery Ventures, pushing its total capital raised to $78 million. Existing backers Bessemer Venture Partners and Coatue also participated in the round.
Construction sector defies broader U.S. job slowdown
The construction industry added 22,000 jobs in August even as overall U.S. employment declined, according to the Bureau of Labor Statistics. AI data center construction drove much of that growth, a trend both the sector and Miter expect to continue.
Miter processes payroll for roughly 2% of U.S. construction workers
Roughly two of every 100 American construction workers are now paid through Miter's platform, which contractors use to coordinate workforce management, field operations, job costing and expenses across hundreds of thousands of active jobs monthly. The company has tripled its customer count since announcing its Series A round in May 2025.
Clayco and Haugland Group among current enterprise customers
Miter's client base includes Clayco, an Engineering News-Record Top 5 design-build firm, and Haugland Group, a union-strong infrastructure services organization with more than 1,600 employees operating across energy, heavy civil, marine and logistics.
Company targets construction's 'Frankenstack' of outdated tools
CEO Connor Watumull, who co-founded Miter with Tobin Paxton, said most contractors rely on a patchwork of 1980s-era software, spreadsheets and paper to manage operations -- partly due to construction-specific accounting and payroll complexity. Job costing, prevailing wage compliance, certified payroll reporting on public projects, multi-state tax withholding for mobile crews, and OSHA recordkeeping requirements create layered compliance burdens that legacy systems struggle to handle.
New capital to fund AI product expansion and engineering hires
Miter will use the Series B proceeds to expand AI products for back-office and jobsite functions, grow its engineering teams in San Francisco and New York, and scale go-to-market operations across the U.S. The platform already applies AI to parse invoices, receipts and pay rate tables, automate contractor workflows, and generate safety reports from photos or voice notes in the field.
Battery Ventures general partner Michael Brown said the construction industry's complexity has historically deterred technology providers from building tools suited to its specific compliance and operational demands. Brown cited the traction achieved by Watumull and Paxton's team as evidence the platform can take on more manual work currently performed by contractors.
