Marius Meiners
Marius Meiners is the co-founder and CEO of Peec AI, a Berlin company that tells brands whether ChatGPT, Perplexity, and Gemini mention them - and how. A former top-100 League of Legends player who later worked in venture capital and M&A at PwC before joining Antler's Berlin cohort, he vibe-coded Peec's first prototype in a day and a half with V0 after not writing code for four years, signed eight letters of intent before building the real product, and priced it at 85 euros a month while competitors charged 500-plus. Peec launched in February 2025 and crossed roughly 10 million dollars in annualized revenue about 15 months later, raising about 29 million dollars from investors including Singular, 20VC, and Antler.
