No spam. We'll email you the audit and one follow-up. That's it.

Your competitors aren't winning more bids. They're following up more. That's the whole game now.

Why this matters in 2026

Private equity just made this a survival issue.

PE rollups — Sila, Champions Group, Apex Service Partners — are buying HVAC shops at premium multiples. But only the shops that show systematized revenue operations.

Shops still running on memory and sticky notes are getting marked down 2–3x EBITDA at exit. The shops winning the bidding wars all have one thing in common: documented, automated customer follow-up.

The system we build for you

We install a four-step recovery system in your shop. No new software. No retraining your team.

1

We plug into ServiceTitan, Housecall Pro, or Jobber.

Your existing CRM stays. We read every estimate as it's created — no rip-and-replace, no data migration.

2

We launch a 14-day SMS + email + voice recovery sequence.

Personalized to the customer, the equipment quoted, and the price tier. Sent from YOUR shop's number, in YOUR voice.

3

We re-quote when distributor pricing moves.

Copper up 8%? Equipment lead times stretching? We auto-refresh the estimate and resend before it goes stale.

4

We hand back warm replies to your closers.

Your team only touches customers who responded. The AI handles everything else — silently, in the background, 24/7.

Who we are

Built by an operator. Not an agency.

Grand Scale AI is run by an operator who spent years inside service businesses before building automation systems for them. We work with a small number of shops at a time — that's the only way to do this right. If we're not the right fit, we'll tell you.

GS
Real questions

Things shops actually ask us.

No. We sit on top of your existing CRM. We read estimate data via API or webhook, run the follow-up sequence, and write replies back into the customer record. Nothing changes for your office or techs.

Stop guessing. Start measuring.

The audit takes 90 seconds to request. It'll save you a year of leaving money on the table.
