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 the Marketplace Trust and Safety Team

Building a trustworthy marketplace is one of the biggest challenges in bringing local services online. It is one of the keys to Thumbtack’s continued success and growth. The Marketplace Trust and Safety team is responsible for building the systems that guarantee this trust, by improving the fundamental quality of our marketplace.

The team’s work is deeply technical and spans a wide range of domains from infrastructure to machine learning models to product features. Recent examples include: training and running machine learning models in production to block abusive requests, to building a linked accounts detection system backed by a graph >100MM nodes to understand which users may have relationships with each other, to improving our pro credentials products by providing high quality, validated pro credentials that increase customers’ trust when hiring on Thumbtack.
