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)

Who is behind it

  • David Shijoon Bae, Founder/CEO: Co-founder & CEO @ FlowManual. Automating Construction Contract Procurement. Previously MechE @ Harvard. (source)
  • Michael Lin, Founder/CTO: Co-Founder and CTO at FlowManual. Previously SWE intern at Dijie, where he built a video-based landing page that scaled revenue from $3K to $336K MRR and reduced latency from 800ms to 100ms. Published CS researcher at UC Santa Cruz, co-authored paper submitted to IEEE IV 2025. (source)
