Infrastructure for the Next Generation of Acquisition Entrepreneurs

Our Thesis

Turnstone was built to solve two of the biggest challenges in acquisitions: generating proprietary deal flow and scaling portfolio companies.

Our Core Principles

Execute

At Turnstone, we believe there is no replacement for getting the work done. We deliver, no matter what. Plan your attack, but make sure to actually attack. Don't hesitate to implement your plan as you fight dragons and storm the castle.

Adapt

Business success is never a straight line, and in our pursuit of the grand prize, we are prepared to pivot if necessary. Optimists expect the clouds to pass, pessimists curse the storm, but realists adjust the sails.

Win

Our culture is centered on finishing the job with the maximum benefit of all parties involved. No painful platitudes about win-wins. Just win. Win with class. Win with humility. But win. There is nothing like getting to the finish line first.

Our Founder

Eric Stopper

Founder & CEO

Eric built Turnstone after working across partnerships, automation, and revenue operations.

After seeing how inefficient deal sourcing can be, he began developing systems that combine AI, automation, and targeted outreach to generate acquisition opportunities at scale.

Today, Turnstone helps investors build repeatable deal origination engines and deploy growth infrastructure across portfolio companies.
