Lemon · Insights, reimagined

Insights from human judgment. AI built around you.

I help small and mid-sized businesses understand their customers the way the big players do. The judgment comes from 25 years of research across four continents. The speed and depth come from custom AI.

01 / The gap we close

Big companies have insight teams. You've got decisions to make.

AI has changed the maths. For the first time, a small team can build real, ongoing customer understanding without a big-company budget behind it. Closing that gap is the whole reason Lemon exists.

Why Lemon

Top-flight thinking, multiplied by AI.

Lemon is me, Carlos Hernandez: a career spent working out what people actually think, feel and do. No juniors learning on your budget.

02 / The habit of looking

Curiosity is the job.

I've worked both sides of the table: the world's leading research and brand consultancies on one side, client-side insight at Reckitt Benckiser and Abbott Labs on the other. The camera came everywhere with me. These frames are mine.

In 2024 I rebuilt the whole practice around AI. The thinking still comes from a person; it just moves faster now and covers more ground. Work with Lemon and you get that judgement directly.

Start small. One free hour.

You might have a brief ready, or half a question, or just doubts about whether AI can really do this. Any of those is a fine place to start.
