Most companies don’t fail to grow. They fail to design for what growth breaks.


Anirvan Sen | Founder & CEO, Fifth Chrome Strategy. Leadership. M&A. Scale.



A different way of thinking about scale


Every founder believes their biggest problem is finding the next deal, the next market, the next hire. It isn’t.

The real problem is that most businesses are structurally designed for the size they are — not the size they’re trying to become. When growth arrives, it doesn’t reveal opportunity. It reveals every crack in the foundation that nobody wanted to look at.

I work at the intersection of strategy, leadership, and M&A because that’s where the real stress fractures appear. Not in the spreadsheet. Not in the pitch deck. In the operating model, the leadership culture, and the decisions that got made before anyone realised they were decisions.

My frameworks — PROMISE, COMBINE, SCALEUP, ELITE Leadership, and the Buy-and-Build Operating System — aren’t theoretical constructs. They were built in the room, under pressure, with real companies trying to scale through real complexity. They exist because the standard advice doesn’t work at the critical inflection points.

If you think scale is a strategy problem, we probably disagree. If you think it’s a leadership and design problem, we should talk.
