I’ve used thumbtack for over a decade off and on and they have take a significant fall from grace. We compete against them in local advertising and they simply are spending too much to be able to offer services like they used to. You can no longer profitably use their service because the cost to acquire a new client is significantly more than it is to just market for them yourself of hire a third party marketing team (we have done both). Flatly just not worth the trouble.
