Former 33eleven Partner joins from Boston to expand the firm’s growth equity practice, with a focus on AI-first leadership talent

Assembly Group, a leading boutique executive search firm serving private equity-backed software and technology companies, today announced that Sam Boynton has joined the firm to further expand its work with growth equity clients. Based in Boston, Sam will focus on helping growth investors and their portfolio companies recruit world-class executive teams, with particular emphasis on executive leaders across functions who can harness AI to drive innovation, transformation, and growth.

Over the past decade, Assembly Group has built its reputation placing executive talent across the C-level for leading private equity sponsors, including TA Associates, Hg, PSG, and Insight Partners. As that work has grown, the firm has seen a clear and continued opportunity in growth equity, where companies are scaling quickly and demand is accelerating for leaders across every function who can put AI to work.

Sam’s arrival represents an exciting next chapter in Assembly’s growth equity practice. He will partner with growth equity investors and the CEOs and founding teams they back, bringing Assembly’s senior-led, high-touch search model to companies at an earlier and faster-moving stage of growth.

“Demand from our growth equity clients keeps building, especially now. In the age of AI, companies are scaling quickly and need top-tier leaders to take them to the next level,” said Carissa Clark, CEO and Founding Partner of Assembly Group. “Sam has spent his career recruiting leaders for exactly these kinds of companies, so bringing him on was a natural fit. He knows the investors and founders, and he cares deeply about the experience of both candidates and clients. He’s a fantastic addition to our team.”
