Innergy
👤 Marc Sanderson (Marc bought an architectural-millwork shop in 1997 and ran it for years, then founded Innergy in 2015 to fix pain he lived daily.)🌐 siteLinkedIn
He bought a millwork shop in 1997, lived its chaos, then in 2015 built the ERP those same shops now rent.
Will it work? · our read
Lived the pain. Not a lucky niche bet — 18 years of shop-floor know-how got encoded into software. The TAM ceiling is real, but inside millwork he is nearly unassailable.

Practical Founders #197 — Marc Sanderson interview (founder-stated revenue, 50%+ growth, about 95% retention, origin story)Mainsail Partners — $44M growth investment (Aug 2024) ($42B live bids, 5M+ sheets processed)Woodworking Network — Marc Sanderson market-leader profileInnergy pricing and product tiersPRWeb — Innergy $44M Mainsail investment release
Revenue (about $25M, 2025), 50%+ growth and about 95% retention are founder-stated on the Practical Founders podcast (STATED, not audited) — marked verified as a first-party on-air disclosure. The $42B in live bids and 5M+ sheets are cumulative platform stats from Mainsail's release, NOT revenue. Mainsail's $44M growth investment is public (Aug 2024 PR); the "51% majority for $40M+ in 2025" framing comes from the podcast summary and may conflate the same deal. The insider-advantage read is [our read], strongly supported by the documented 1997 shop purchase and 2015 Innergy founding. We never score you.
