Turning customer stories into drivers of revenue growth | Founder of Sproutworth

B2B growth gets chaotic just when it starts working.

Early wins feel like momentum, but momentum doesn’t scale. What drove your initial traction stops working. More tactics, more hires, more tools… and suddenly revenue becomes harder to predict, not easier.

I help B2B leaders turn chaos into predictable revenue.

As host of Predictable B2B Success (500+ conversations with B2B founders, execs, and operators), I study patterns behind what actually works once a company moves beyond early wins. Most revenue chaos comes from trying to scale what worked early instead of changing how growth really scales.

No growth hacks.
No silver bullets.
Just clear thinking. Repeatable frameworks. Real results.

If you’re building or leading a B2B tech company, you’ll feel at home here. And you’ll leave with practical insights you can act on today, not just ideas to nod at and forget tomorrow.

My promise: Stop guessing. Start scaling. Make revenue predictable.

Podcast Host of the Predictable B2B Success Podcast
