FlowManual on the record

What they shipped

  • From its YC profile: FlowManual is the all-in-one AI estimating, bidding, and purchasing platform for both general and MEP construction contractors. Built by two engineers and Harvard dropouts, FlowManual automates the buying process during pre-construction. With FlowManual, specialty contractors win more work while general contractors deliver at higher standards. (source)
  • Its own site describes it as: "The all-in-one AI platform for construction's back office. FlowManual cuts the repetitive work across bid, buyout, and contract review so contractors win more work." (source)
