Technology investor Powerhouse Ventures plans to sell about a quarter of its Invert Robotics shares for $1.3 million, the company announced.

Powerhouse currently holds 34.6% of Invert Robotics, but the sale would decrease that holding to between 23.6% and 28.2%.

“Generally, Powerhouse Ventures aims to own between 20 to 40 percent of its investee companies prior to their expansion rounds when they grow to become ‘post-seed stage’ companies,” the company said in a statement. “Invert has now reached this point and has in place the necessary governance and funding arrangements to succeed.”

The sale would bring in a profit above Invert’s current book valuation and would introduce “new institutional and sophisticated investors” for fundraising as Invert works to expand into the European dairy and aviation industries, Powerhouse chairman Russell Yardley said.

Invert Robotics specializes in remote inspection solutions with its own mobile inspection robot that can climb stainless steel surfaces and provides inspection data to an inspector using sensors and high definition cameras.

Before the deal is finalized though, Powerhouse and Invert must complete the pre-emptive shareholder process and co-sale rights under their shareholder agreement, which could take at least one month.
