Yann Dine

Yann Dine is a Paris-based AI product builder best known as the founder of Prosp, an AI tool that automates personalised LinkedIn outreach for agencies and sales teams, and Speel, an AI generator of UGC-style ad videos. Dine says they have bootstrapped a product from zero to $1 million in annual recurring revenue twice, and both businesses show verified revenue on TrustMRR.

Prosp reads each prospect's profile, headline and recent LinkedIn activity and writes a first line that refers to something specific, then runs the connection and follow-up sequence while staying under LinkedIn's limits. It was on the market by 2023 and grew past $1 million in ARR; TrustMRR showed it at about $128,000 in monthly recurring revenue in October 2026, with more than $500,000 in verified lifetime revenue.

Speel followed in October 2025. It uses AI to produce realistic user-generated-content style videos and images for ads and social media, a category that exploded as brands looked for cheaper creative. Dine reports it went from zero to $1 million ARR in three months; TrustMRR lists its MRR at about $65,000.

Dine's main growth engine has been LinkedIn itself. Dine has said the team generated more than 5 million views on the platform in a year, and regularly shares playbooks, prompts and free toolkits for AI-driven sales and creative production. In 2026 both Prosp and Speel were listed for sale on TrustMRR's marketplace while Dine moved on to Connie, an agentic go-to-market platform that gives AI agents access to more than 1,000 tools and data providers alongside chats, records, workflows and an inbox.

Dine is part of a wave of European indie founders who build quickly on top of large language models, distribute through founder-led content and are comfortable selling one product to fund the next.
