From WhatsApp Groups to Health Tech: How Uche Nnamani Is Building Fitness Space

Uche Nnamani Scales Fitness Space From WhatsApp Groups to Health Tech
New Haven, Enugu, August 24, 2026 — Founder and CEO Uche Nnamani has launched an AI-powered wellness product, Bibi from Fitness Space. This AI-powered platform understands their wellness goals, generates culture-fit meal guidance and home workouts, provides personalised recommendations, and maintains regular interactions and updates that help users stay accountable.

Bibi is also on WhatsApp, where it onboards new users into Fitness Space. Once onboarded, users can access Bibi’s broader features through the Fitness Space app. For example, a user can tell Bibi what foods are available at home. Instead of prescribing a rigid meal plan, Bibi guides them towards putting together a healthier meal using those options..

According to founder and CEO Uche Nnamani, “Our WhatsApp groups were an early testing ground for a bigger idea: it validates that sustainable weight loss requires more than telling people to eat better and exercise. The internet already provides plenty of that information for free. The bigger challenge is helping people turn what they know into consistent everyday actions.”

Nnamani’s approach was influenced by lean product thinking and a principle championed by Netflix co-founder Marc Randolph: Entrepreneurs should find a quick, cheap and easy way to test an idea with real people before investing heavily in building it.

Rather than immediately building an app, Fitness Space started by working directly with people trying to lose weight, using WhatsApp groups as its earliest product. Through the groups, the company provided structured guidance around nutrition, portion control, physical activity and other healthy behaviours, while regular interaction and accountability helped participants stay consistent.

Nnamani reported, “As the programme developed, Fitness Space worked with users in Nigeria and internationally, including participants in the United Kingdom and Canada. The model allowed us to observe their challenges, and gradually refine the system around what users actually needed, which was consistency.”

Those experiences led Nnamani to increasingly view weight loss as a system problem. It was less about providing more information and more about building structures around the daily behaviours that influence weight management.

Fitness Space did not begin by building technology and then searching for a problem. It started by working directly with people trying to lose weight, learned that consistency and everyday behaviour were major challenges, refined its system through those interactions, and subsequently built Bibi to scale that experience.

“The purpose of Bibi was to turn processes developed through direct interaction with users into a platform where nutrition, workouts, daily activity, healthy behaviours and progress could be brought together,” said Nnamani. “Bibi is simply an extension of the WhatsApp groups which still exist.” Learn more about Bibi from Fitness Space: getfitness.space
