Company profile
researched Sep 2026Feeder (legal name FEEDER THE REACTION APP, SL) is a Barcelona company that develops an AI platform using facial recognition to analyse viewers' emotional reactions to video content in real time. Its algorithm processes micro-expressions to detect states such as joy, anger, fear, contempt, calm, disgust, surprise and sadness, and translates them into scores for attention, approval, surprise, displeasure or rejection, so that advertisers and creators can judge how effective a piece of video is. The platform delivers immediate evaluations across formats including videos, calls and streaming, with metrics framed around acceptance, impact and engagement.
The product was initially aimed at marketing professionals and content creators seeking to improve the emotional impact and return on investment of video campaigns. In its consumer-facing app form, brands placing advertising on Feeder were required to offer promotions or discounts to the users whose facial reactions were analysed, and the company stated that captured data would be fully anonymous. Feeder has since extended into health-related use cases, supplying therapists and online coaches with emotional signals from virtual sessions in order to track patient emotional responses, identify emotional patterns and support communication and therapy outcomes. Directory listings classify the company under adtech/media and healthtech, with AI and big data as its core technology.
Founding story
Feeder was created in Barcelona by co-founders Pablo Filomeno and Mauro Gadaleta, who built an algorithm to read the small, unconscious expressions viewers make while watching advertising. The company presented the algorithm at the 4 Years From Now (4YFN) event held alongside Mobile World Congress in 2021, backed by an initial investment of €30,000.
Business model
B2B, sold to businesses through a mix of SaaS subscription, software licensing and consultancy/agency services, per the Catalonia Startup Hub directory listing.
Traction
Around 20 clients, including marketing agencies, influencers and brands, were testing the product ahead of launch as of August 2021, when the company projected roughly €40,000 of 2021 revenue and 50 clients. Pilots were subsequently reported in Spain and Taiwan.
Latest developments
El Referente's February 2025 profile lists the company as open, with a stated 2025 company valuation of €3,000,000, share capital of €3,775, and an expansion of the platform from marketing into the health sector for therapists and coaches, supported by pilots in Spain and Taiwan.
