Entering a niche already occupied by Intol, Allergy Eats, Food Intolerances, and Yuka, Food Filter's founder envisioned it as a competitor to well-known food trackers like MyFitnessPal and Lose It!. To secure a place in the market, the team needed to find an untouched niche—a problem not addressed by existing products. They devised a 3-step validation strategy, combining research and tests to gain deep insights into current market needs.

We utilized the Mobile App Rating Scale to assess the functionality of existing food allergy apps. Existing apps had limited functionality in proposing or filtering recipes based on specific food allergies. There was only one startup collaborating with restaurants to make recipes transparent for those worried about accidentally consuming allergens on dates. Competitors' positive metrics, revenue, and raised funds indicated potential demand. Unfortunately, this method provides about 20% accuracy in startup success probability, so we progressed to the next stage.
