"In the last year we replaced over 10 third-party softwares, including HubSpot, Shopify, and others. ... Roughly $10k/month. It was important for us to cut out much of the HubSpot noise we didn't need and build custom sales workflows (pricing calculators, quotes, contracts) that connect directly to our production planner, SKUs, and IMS."

From a public post

Was paying $500 / month before

Colin Stoner, Novo Construction · Aug 26, 2026

From a public post

"Novo, a 400-person Bay Area general contractor, passed on Procore in 2011 and built Sentinel. 14 years of its own project data now drive AI-drafted RFIs, about 99% automated insurance certificate processing and auto-generated three-week look-aheads. It still licenses outside tools that do one job well."

HubSpot and Salesforce
