Ultrahuman: To Be a Cyborg or Not?

Ultrahuman is an "advanced metabolic fitness platform" that tracks metabolism through continuous glucose monitoring (CGM). An arm patch monitors blood glucose levels in real-time. The target market: fitness enthusiasts who want to optimize their health at the cellular level.

I spent time on their website trying to understand whether this product was for me. I'm still not sure it's for anyone without diabetes.

Website Critique

Unclear value proposition: The site fails to convincingly connect glucose tracking to fitness outcomes. The question I kept asking: "If I buy this today, will I be able to lift more or run faster?" The website never answered it.

Confusing language: Terms like "biomarkers" and "biohackers" create barriers for general audiences. If your product is for everyday fitness enthusiasts, lead with everyday language.

Vague messaging: "Maximize your diet and exercise based on glucose biomarkers" doesn't tell me whether I should eat more or less. Balance? Increase? The copy assumes prior knowledge that most users don't have.

Missing integrations: The website could showcase combined data — glucose plus heart rate, calories burned, oxygen levels from wearables. That integration story is the compelling pitch. It's missing.

The Core Problem

A Harvard Medical School article questions whether glucose tracking in non-diabetic patients is actually useful. Ultrahuman explicitly avoids marketing to diabetics — the population where this product has proven clinical value — and instead targets healthy fitness enthusiasts, where evidence for the practice is thin.

The paradox: the product is most useful for people they've decided not to sell to.

Ultrahuman has a genuinely interesting technology. But until the science catches up with the use case they're targeting, the value proposition for the average gym-goer remains unconvincing.
