Moonpig Founder: How I Built A $150 Million Business WITHOUT Sacrifice: Nick Jenkins | E97

Jenkins used statistics to calculate the minimum marketing spend needed for a ‘statistically significant’ cost of customer acquisition, often spending £2,500 instead of £25,000 to test a channel. He frames half of that test budget as acquiring customers at the right price and half as paying to learn what never to do again. Entrepreneurs should design very small, focused experiments to test their riskiest assumptions (e.g., using a shipping container gym in a service station rather than opening 10 full sites).

Moonpig entered a market where personalization and greeting cards already existed, and there were even direct competitors. Jenkins emphasizes that most wealth is built by improving existing models—like making ‘better bread’ rather than inventing bread itself. Focus on a known demand and then win on 1,000 small details: product quality, design, convenience, margins, and operations. The question is not “is this unique?” but “where can I be meaningfully better?”

Moonpig survived a year with zero marketing spend yet grew 30% because customers loved the product and it had a built-in viral loop (recipients saw ‘moonpig.com’ on the back of cards). Jenkins monitored repeat rates and the ‘viral coefficient’ (each customer brought ~0.33 new customers). This data convinced him to persist when everyone else thought the business would fail. Entrepreneurs should obsess over whether people truly value the product and how usage creates organic growth.

As an investor, Jenkins refuses to back founders running multiple startups and even contractually restricts significant outside interests. When things get hard, humans naturally drift toward the easier project, starving the one that most needs attention. Given how hard it is to succeed even at 100% focus, spreading yourself across two or three early-stage companies almost guarantees failure in all of them.

Contrary to ‘hustle porn’, Jenkins maintained a good social life and tried to run Moonpig largely within sensible working hours. He only worked extreme hours in genuine emergencies (e.g., personally running the printers 24/7 for three days when the entire print team was sick). He believes exhausted teams are less creative and effective, and he consciously avoids building a culture where people ‘sacrifice themselves on the altar’ of the business.
