The brands that won weren't the best. They were the most seen.
That's the insight behind Ampy.
Karl Newlin is the Founder & CEO of Ampy, mission control for B2B distribution.
Karl is the growth lead founders wish they could hire — and now they can.
Before Ampy: 14 years running growth at Stripe, Carta, Gusto, Upwork, Step, and Mutiny. $30M+ in paid social budgets. Seed to IPO. The same lesson, over and over:
Great content. Good engagement. Flat pipeline.
The fix wasn't better creative. It was showing up more — to the right accounts, in the right sequence.
The short version
Now: Building Ampy. Also advising B2B teams as a fractional Head of Growth — turning founder profiles into acquisition channels.
Before: Stripe ($30M paid social budget), Step (0 to 1M users in 6 months), Carta ($30M → $150M ARR), Gusto (thousands to 60K users), Upwork, Mutiny.
The through-line: Figuring out what actually moves pipeline — not just dashboards.
Where Ampy came from
At Mutiny, I ran an experiment.
Instead of boosting exec posts randomly, I sequenced them. Same target accounts saw a series of posts over 4–6 weeks. Problem → insight → proof → invitation.
Results:
- •10–20% engagement (vs. 1–2% typical)
- •$200 cost per conversion (vs. $600 non-sequenced)
- •Buyers recognized the name before sales ever called
The playbook worked. The problem: doing it manually takes 25+ hours per month.
So I built Ampy.
