Who We Are
Ai4Sellers is a technology startup specialised in the concept of Commercial SuperAgency. We develop artificial intelligence solutions that amplify the capabilities of sales professionals, enabling commercial teams to sell with more intelligence, speed, and consistency.
We were founded on 27 January 2025, inspired by the same date in 2016 when artificial intelligence shocked the world by proving it could think beyond humans. That was when DeepMind revealed AlphaGo, the first machine to defeat a professional player in a game of Go — a challenge that, for decades, was considered impossible for technology.
To contribute to more productive, intelligent, and profitable commercial teams through the strategic use of artificial intelligence. We make this happen through:
AI for sales simulations that trains, develops, and accelerates the learning curve of salespeople.
Conversational AI that provides real-time strategic information, reduces uncertainty, and improves decisions.
Agentic AI that executes operational tasks, frees up time, and increases productivity.
AI Copilot that accompanies the commercial routine, guides actions, and sustains performance continuously.
Full AI Training of 21 hours.
Development of retail diagnostics using AI, consultancy for AI implementation in store management, and production of video lessons for B2C and B2B salespeople.
Migration from traditional Corporate Academy to AI Training Copilot.
