Groundwork vs Thumbtack
Thumbtack charges $8–$150 for a lead it also sells to your competitors. We charge $2.60 for a permit record only you and a few capped seats receive.

- Lead quality is the standing complaint: spam, wrong numbers, tyre-kickers
- You are bidding against everyone who bought the same lead
Groundwork — $39/mo
- $39/mo flat, whatever the week looks like — about $2.60 a lead
- Up to 15 job sites every Tuesday for your trade and your side of town

The short version
One Thumbtack HVAC lead can cost more than a whole month here. $39/mo is $2.60 a lead at 15 — and nobody else is calling the same list from a shared queue.
What you get here for $39
- Up to 15 job sites every Tuesday — about $2.60 a lead.

- ${list(tierNames('A').map(escapeHtml))} leads are owner-pulled: an individual, one property, no contractor named on the permit.
