Boston-based Tempo Software is acquiring LiquidPlanner, the 17-year-old Seattle-based startup that sells a suite of productivity software tools to businesses.

Terms of the acquisition were not disclosed.

LiquidPlanner’s 27 employees will join Tempo as part of the acquisition, bringing its post-acquisition workforce to more than 350.

Tempo said it will list LiquidPlanner’s predictive scheduling and capacity planning software on the Atlassian Marketplace, an online store for third-party add-ons, plugins and extensions for Atlassian products.

“This is a monumental day for LiquidPlanner as we merge with Tempo’s award-winning solutions and bring our powerful capabilities to the Atlassian Marketplace,” LiquidPlanner CEO Ted Hawksford said in a statement.

The acquisition comes at a time when startup M&A activity has dropped off amid interest rate hikes by the Federal Reserve. Deal count slipped to 129 deals in Q4, down 28% from the first quarter of the year, capitalization table software startup Carta reported in February.

Co-founded by Charles Seybold and Jason Carlson, LiquidPlanner offers a predictive scheduling engine that uses priorities, capacity data, and work estimates to create schedules. Other features include time tracking, workload management and real-time insights.

The company sells software to businesses of all sizes and integrates with popular platforms like Slack, with an open API for custom integrations. Customers include KPMG, Delta Airlines, and Bayer, among others.

The startup, launched in 2006, has been led by four CEOs. Seybold held the role until 2012 and was succeeded by Liz Pearce, who was CEO for more than five years. In 2017 Todd Humphrey took over, and two years later Hawksford was named CEO.

LiquidPlanner reached profitability in 2018 and raised about $17 million. Its backers include TVC Capital and Seattle angel investors Geoff Entress and Bill Bryant, among others.

Founded in 2015, Tempo is one of the largest software vendors on the Atlassian Marketplace, serving more than 28,000 customers across 100 countries. The company said it recently surpassed $100 million in annual recurring revenue and is profitable.
