About Rensei
RENSEI LLC was formed in New York on May 28, 2026, by Katsuko Lord, who filed personally as the registered agent. The company is based in Manhattan and appears to be a solo-founder enterprise AI software startup focused on LLM workflow orchestration. Its website describes an AI workflow platform built by a solo founder with 43 days of active development, suggesting a very early-stage, pre-revenue business. We estimate revenue under $100K and a team of 1 to 5 people, likely just the founder. The business is online-only with no physical storefront. The domain was registered before the filing, and the website is a modern build using a JavaScript framework, responsive CSS, structured data, and OG tags, with a 2026 copyright. The site was first recorded here on May 30, 2026, just two days after the filing. Notably, the owner filed the LLC personally rather than through a formation service, and the domain name matches the LLC name exactly, reinforcing the identity. No annual report or EIN on file yet.
