Our take
In the US, there's been a booming demand for home-service businesses, yet historically many of these trades were running with outdated software systems. That's where ServiceTitan comes in. Founded by friends who grew up around the trades, the company saw a clear gap and set out to give contractors the modern platform they desperately needed.
ServiceTitan's platform is designed specifically for the trades and brings together everything a contractor might need, in one handy system. By focusing on what trade-business owners actually need, it helps turn chaos into structure, giving visibility into operations, so owners can ultimately run their business better.
Now, ServiceTitan serves more than 11,800 trade customers and reported more than $10,000 in annualized billings and processes a huge volume of jobs on its platform. With a market that's still under-served by technology and a platform built to scale, the company is ready to grow even further.
