Hajoca, one of the largest privately-held wholesale distributors of plumbing, HVAC and industrial supplies in the U.S., has acquired Onsemble — a software provider developing intuitive, AI-enabled tools that help contractors grow.

Onsemble will serve as a dedicated digital innovation engine within Hajoca, focused on delivering modern, contractor-first tools – particularly to small and midsized plumbing businesses.

Founded by Rick Klau and Julia Yrani and originally backed by Silicon Valley investors, Onsemble assembled a team that has spent the last several years developing technology with and for contractors.

“We built Onsemble because too many contractors are left behind by tech that doesn’t understand their world,” said Rick Klau, Co-Founder and CEO of Onsemble. “Joining Hajoca gives us the resources and reach to serve those contractors better than ever.”

Hajoca told MDM that the Onsemble team will remain intact and focused on delivering solutions that support Hajoca’s long-term contractor strategy.

“This is a bold move by Hajoca – and a win for the trades,” Onsemble Co-Founder and President Julia Yrani told MDM. “Together, we’re committed to building simple, impactful tools that meet contractors where they are and help grow their businesses.”

“Contractors are at the heart of everything we do,” added Rick Fantham, President and CEO of Hajoca. “Partnering with Onsemble accelerates our ability to serve them with an expanded suite of digital tools that save time, simplify workflows, and support their success.”

Based in Lafayette Hill, PA and founded in 1858, Hajoca consists of 450+ locally-managed locations operating under more than 60 different regionally established trade names.
