Data Scientist, Machine Learning

Thumbtack, San Francisco

We’re building the destination for getting things done

Have you ever tried to hire a plumber? How about a house cleaner? If you have, chances are it took you way longer than it should. In the era of instant-everything, it’s crazy that you still have to waste an entire afternoon researching, calling and vetting local service professionals whenever you need one. The market for hiring them is huge — $700B in the US alone — but the process is inefficient and largely offline.

Thumbtack is transforming this experience end-to-end, building a marketplace that matches millions of people with local pros for almost any project. In making these connections, not only do our customers get more done every day, our pros are able to grow their businesses and make a living doing what they’re great at.

About Thumbtack

Solving one big problem In 2009, three friends—Marco, Jonathan, and Sander—noticed a problem. Customers needed help connecting to qualified, local professionals. The same professionals needed customers. As a solution to bring the two together, Thumbtack was born. Since then, we’ve helped millions of customers with their projects and generated more than $1 billion in annual revenue for our pros. We’re reshaping local economies. We’re changing lives. And true to the spirit of our customers and pros, we’re getting things done.
