About Marcus Jecklin
Marcus Jecklin is a co-founder of Ai4, RETCON (the Real Estate Technology Conference) and Fora Group, and is based in New York. Crunchbase lists his title at Ai4 as Co-Founder and Head of Ops. It also lists him as a co-founder of the Banking Transformation Forum and, previously, of Worlds Fair USA.
In a CTO Magazine interview he said Ai4 started in Brooklyn in 2018 with 300 attendees. He described his own focus as marketing: the brand, attendance and engagement. He said he and co-founder Michael Weiss produced many events together before launching Ai4.
Before running conferences he worked in commercial real estate investment sales, including at EPIC Commercial Realty and Massey Knakal. He also co-owned a bike business. He holds a B.A. in Psychology from Washington University in St. Louis.
Crunchbase shows one personal investment for Jecklin, in Pomo's seed round, and the amount he invested is not disclosed. No other angel investments, fund activity or investing statements by him turned up in public sources.
Pomo announced a $4.5M seed round on April 8, 2026. The round was led by Kindred Ventures, with Databricks Ventures, 645 Ventures, SV Angel, Seven Stars and Timeless Partners participating. The press release says Ai4 partnered early with Pomo on marketing for its 2026 conference, and that Jecklin joined as an investor. Pomo builds an agentic marketing intelligence platform for mid-market companies.
Jecklin has not published a thesis, preferred stage or check size. The one documented investment is a seed round in an AI application company. It came out of a commercial relationship with his own company, Ai4. Founders should treat any wider focus as unconfirmed and ask him directly.
