Accel-KKR has US$4 billion of funds under management and said it has invested in more than 100 companies since its 2000 start-up, focusing on mid-market software and technology-enabled services firms.
Seequent supplies geology modelling and management software to the mining, civil engineering, geothermal energy and environmental services industries. It has 13 offices and said its technology is used in more than 90 countries. Its flagship product is its Leapfrog 3D geological modelling software.
Seequent CEO Shaun Maloney described Accel-KKR as "a great fit" and an investor that "wholeheartedly support our growth plan and the direction of the business".
"We'll continue our focus on mining and minerals, energy, and more recently the civil and environmental engineering sectors," Maloney said.
"Accel-KKR will bring very valuable business expertise and networks into new global markets, which will be particularly valuable for our newly launched Leapfrog Works for the civil and environmental sectors which represent an enormous opportunity."
Menlo Park, California-based Accel-KKR said Seequent "has a well-deserved reputation as a world-leading innovator in visual data science and has carved out some fantastic markets for its implicit modelling solutions and other collaboration technologies".
"We're excited about the opportunity to work alongside the management team and board and look forward to investing in new innovation and markets to help Seequent build significant value," Jacobson said.
