Origin story

The problem we lived.

Athletes are the most data-rich humans alive. GPS routes, power outputs, heart rate curves, VO2 estimates. But every nutrition app treats everyone the same — static calorie targets regardless of what you did that day.

We'd do a 4-hour ride and still see the same 2,000 kcal target. Then get "grilled chicken and veg" suggested for the third time. And actually ordering the right food? A 30-minute research task every evening.

"Your training data finally tells your kitchen what to do. The guesswork is gone."

Company history

From frustration to product.

2024

The frustration becomes a plan

Two cyclists finish a 200km sportive and realise every nutrition app still shows a static 2,000 kcal target. The problem is obvious. The solution isn't built yet.

Jan 2025

Private beta with 50 athletes

First Strava integration goes live. 50 hand-picked cyclists and runners test real-time TDEE calculations. 94% say it's the first app that actually adjusts to their training.

Jun 2025

Smart cart ships

Uber Eats integration completes the loop — the Jonno Agent now doesn't just tell you what to eat, it builds the cart. Recovery meals, ordered in under 60 seconds.

2026

Public launch

12,400+ athletes onboard across 34 countries. The Jonno Agent handles training nutrition so athletes can focus on training.

How we work

What we believe in.

"Train like a pro. Eat like you know why."

Data-Driven Recovery

Every macro recommendation is grounded in your actual training load. No generic advice. No one-size-fits-all targets. Your numbers, your plan.

AI-First Coaching

The Jonno Agent isn't a calculator with a chat interface. It reasons across your training history, food preferences, and goals to give context-aware recommendations.

Athlete-Obsessed Design

Every screen is built for athletes who are moving fast, not sitting at a desk. Glanceable, dark, fast. No bloat. No wellness-speak.

Technology

Built on the best APIs.

We didn't build a new AI. We orchestrated the world's best tools into one athlete-first workflow.

Anthropic Claude

The AI brain

Claude API powers the Jonno Agent — reasoning across nutrition data, activity history, and food preferences to generate genuinely useful advice.

Strava API

Activity intelligence

Real-time OAuth sync pulls your workouts, calculates TDEE, and feeds that data directly to the AI. Your nutrition targets move every time you move.

Uber Direct API

Seamless delivery

The integration means the Jonno Agent doesn't just tell you what to eat — it builds the cart, surfaces macro-matched options from restaurants near you, and removes the friction.
