Not so much - posted 3 projects on thumbtack...
1st post - didn't work out: fault of NO ONE, things happen (or don't) no problem.
2nd post - change of plans, cancelled TACK but continued to be contacted/harassed by potential companies. If I don't want to use your service "Mr. Floor person" please don't continue to contact me ask how much someone else is charging me... really?
3rd post - I hired movers based on their rating. Spent more money repairing what was broken than the cost of the movers.
Thumbtack "integrity" spent more time calling and telling me they were going to ask me questions than actually doing anything!
I have never heard back from thumbtack!
