Complaint / review text:
I spent over $100 sending quotes to customers. Out of 20 quotes, only two replied, and they were "just shopping around" and not ready to buy. That's the problem with Thumbtack, most customers requesting quotes don't understand you have to pay to give them a quote, and they might be just curious, or not ready to buy. They might come back in a few months to buy or they might just buy somewhere else. Either way, you've lost your money to Thumbtack.
Also, most requests are vague. They don't specify what their price range is or what exactly they need, so you waste money on blindly guessing what they want to pay.
You should also know that most of the positive reviews for Thumbtack are left by Thumbtack employees. They're fake reviews. They don't even bother to use a fake name. There are many screenshots of this at the Thumbtack Complaints page on Facebook.
I like the idea of Thumbtack, and if you only had to pay if you got hired, I'd be very happy with it. But as it stands right now, they're just taking your money for nothing in return. Poor small business owners can't afford to throw money away on nothing. Shame on you Thumbtack.
