For Mike Dolan

An RFP in, a draft AV proposal out.

We read through coltranesystems.com and built this before reaching out. We started with your Sales Engineers, because proposals are where their hours go.

From RFP to draft proposal

A sample walkthrough on one made-up bid shaped like Coltrane work: a healthcare training center with AV, security, cabling and sound masking. See prepared drafts of the scope, the BOM, the RFI list and the cover letter, and what an addendum could change. A Sales Engineer would review every draft before anything goes out.

Who built this

MarkSet is a St. Louis company that helps contractors put AI to work on the office work around a job: estimates, proposals, RFIs and project records. It is led by Dylan Hampton, a Missouri S&T graduate with several years as a software engineer. MarkSet has run paid Claude training for a St. Louis mechanical contractor's project managers and tested estimate drafting on their past jobs, and is developing company knowledge systems that answer questions from a contractor's own records.
