What I learned from 479 mentor sessions with founders

Six recurring patterns in growth conversations with founders across Seed to Series B AI and B2B SaaS. The constraint is rarely the channel.

After 479 mentor sessions with founders, the questions rhyme.

A founder books 30 minutes saying “I need help with paid acquisition.” Forty-five seconds in, it becomes clear the actual problem is positioning. Their landing page promises three different things to three different audiences and the paid traffic is bouncing because nobody knows whose problem this is.

That’s the most common pattern. Here are six more.

1. The “channel question” is almost always a positioning question

Founders ask: “Should we double down on outbound or paid?” The honest answer is: neither, until the offer pattern-matches to a buyer.

If you can’t write the offer in one sentence that a buyer would forward to a colleague, more channel spend will just amplify the unclear message faster.

2. Activation-quality is upstream of churn

Teams come asking about churn. Almost always the real problem is activation: the user never hit the moment of value, so retention was never possible.

Don’t optimise the lifecycle email. Cut onboarding to the shortest path that proves value, then look at retention again.

3. Founders over-research and under-test

The amount of customer-call analysis a founder can do before shipping a single test is astonishing. Customer research is necessary but not sufficient.

The 1-hour customer call beats the 6-week consultancy report. So does the £200 ad test that proves a hypothesis dead.

4. “Hire a CMO” is rarely the right next move

About one in three founders who book a session say they’re about to hire a CMO. About one in twenty are actually ready.

The other 19 need: clearer GTM priorities, a single dashboard, a weekly cadence, and an experiment backlog. Hiring a senior leader into chaos burns the leader and costs the company £150k. Build the system first.

5. “Reporting” is the hidden constraint

Growth reporting either drives decisions or it doesn’t. Most reports don’t.

Teams produce activity reports — impressions, clicks, MQLs — and call it growth reporting. The test: read your last weekly report. What scale-or-stop call did it produce? If the answer is “none,” reporting is your bottleneck.

6. Founder-led works longer than founders think

Founders apologise for “still doing growth myself” at 3M ARR. Often it’s still the right call.

The transition isn’t “stop being founder-led.” It’s “stop being the only person who can read the numbers and make a call.” Build the operating system, train one person to run it, then step out. Two months, not two years.

What this means for your next decision

If you’re stuck between channels, agencies, hires, or tools — the answer almost certainly isn’t on that menu. The answer is one layer up: the offer, the operating system, or the cadence.

Book a 20-minute call if you want a sharper read on which one matters for your company.
