Constor GTM brain

Constor automates construction quantity takeoffs from plans for trade contractors, especially insulation and HVAC businesses.

market profile

text: Manual takeoffs consume estimators' time and can keep subcontractor owners working on bids outside jobsite hours.
text: Constor detects quantities including piping, ducts and equipment from PDF plans and offers a 3D view for checking.

title: Insulation subcontractor owner
pains:
- Manual measurements take evenings and weekends
- Limited estimating time constrains the number of bids the business can pursue
title: HVAC or mechanical estimator
pains:
- Counting piping, ductwork and equipment across plan sets takes hours
- Missed or incorrect quantities can undermine bid margins
title: Preconstruction manager
pains:
- Needs a repeatable way to check quantities and turn plans into quotes quickly
- Training the team on complex tools can slow adoption

text: Construction subcontractors, especially insulation and HVAC trades, with recurring PDF plan sets and estimating work; headcount is not established.
text: Owner-led trade businesses where the principal or a small estimating team spends substantial time on takeoffs; French-speaking customers appear in website testimonials.

objection: Can the AI count accurately enough for our bids?
response: Test a real plan set against a completed manual takeoff and review the output before using it in a quote.
objection: Our team cannot afford a complicated implementation.
response: Demonstrate PDF upload and the checking workflow using one familiar project.

bio: Co-founder at Constor (YC F26). IRONMAN triathlete. Since middle school, I've helped my dad's 20-year-old insulation company with quantity takeoffs, each plan taking hours by hand. That's the problem we're now solving at Constor. Did the takeoff for the Grand Palais renovation for the Paris 2024 Olympics (€170K estimate). Ex-PM at LegalPlace: built a payments tool that drove €1.2M in revenue. Engineer (EPF), then HEC Paris (X-HEC Entrepreneurs).
