Helping Knowledge-Based Firms Break Through Their Growth Ceiling
We help ambitious professional services firms transform founder - or partner-led growth into a scalable, repeatable commercial engine, so your business can win bigger clients, grow sustainably, and increase valuation.
You’ve built a successful professional services business — but growth has stalled.
Too much of the pipeline depends on you or a small group of partners
Word-of-mouth and referrals aren’t enough anymore
Sales hires or BD managers haven’t delivered as hoped
You’re burning energy on winning work instead of delivering it
Competing firms are growing faster, with sharper positioning and processes
The result? A growth ceiling that feels impossible to break.
“James is exceptional to work with. He came into WeTransfer and was able to really quickly understand the business, our requirements and key stakeholders in order to solve critical problems. He is autonomous, a great thinker, and is able to manage complex projects, always thinking outside the box for solutions. As well as this, he is a great person to work with, with an extremely positive attitude. I would work with James again in a heartbeat!”
Irina Dima, VP Strategy & GTM at WeTransfer
