FlowManual is an AI platform for the back office of construction contractors. It reads specs, contracts, quotes, and invoices and automatically marks up scope, prices, deadlines, and exclusions, then compares bids against signed contracts and invoices against locked buyout prices to flag every scope change and price drift by severity and dollar impact. Founded in 2026 by Harvard dropouts David Shijoon Bae and Michael Lin, the company is part of Y Combinator's Summer 2026 batch and aims to cut the repetitive manual work of pre-construction so contractors can bid more and deliver at a higher standard.
Clearstory is a cloud-based change order communication platform for commercial construction. It gives general contractors, specialty contractors and project owners a shared, real-time system to create, price, track and align on change orders and time-and-material (T&M) tags - the extra work that traditionally gets buried in email, PDFs and spreadsheets. Founded in 2018 as Extracker and rebranded to Clearstory in 2023, the company runs a business network where contractors exchange roughly $1B in change orders every month, and counts many of North America's largest general contractors as customers.
Pegbo is a Menlo Park construction-technology startup that gives preconstruction teams AI coworkers to source, engage, and vet trade partners. Its platform searches a database of more than one million verified subcontractors and suppliers - filterable by scope, location, NAICS code, union status, and certifications like MBE, DBE, and WBE - then automates outreach, bid-coverage tracking, document collection, and compliance so general contractors and project owners can hit supplier-diversity goals faster and with less busywork.
Roger (legally Iris Technologies) is a Salt Lake City-based construction-tech startup building an AI-powered collaboration workspace for construction project managers.

Its AI drafts follow-up emails, chases vendors on long-lead items, updates logs, and keeps details from slipping through the cracks - aiming to make every project run like a team's best project.

Jon Sibley is the Founder and CEO of TrueBuilt Software, an AI-native preconstruction platform headquartered in Huntington Beach, California. A former NCAA Division I water polo player at UC Berkeley and Team USA competitor, Sibley translated elite-sport discipline into enterprise software sales at Quid and Visa before founding TrueBuilt in July 2022. The company raised a $4 million seed round in 2023 led by Bienville Capital with participation from Fifth Wall, and in late 2025 acquired Capabuild — a mobile field documentation platform — driving a 124% revenue increase in three months post-close. TrueBuilt consolidates what was once a fragmented 6-8 tool preconstruction workflow into a single AI-powered platform serving general contractors and subcontractors.

Doxel is a Menlo Park-based construction technology company that uses computer vision and AI to automatically track what is actually being built on large, complex job sites.

It has tracked billions of square feet of work for Fortune 500 customers including Kaiser Permanente, Shell, HCA and major data center developers.
