About Rasyn
Summary
Rasyn designs industrial compounds and formulations using AI-driven chemistry models, targeting manufacturers that need custom chemical solutions for applications such as cooling, catalysis, and crystal design. The company takes a client's property requirements, operating conditions, and material constraints, then designs molecular structures or formulations, produces samples, and validates them against specifications. This replaces the conventional trial-and-error lab process for industrial chemical development.
Business model
A fee per chemical development project.
Go-to-market
Industrial manufacturers and chemical buyers engage Rasyn project-by-project by submitting their requirements directly through the company's site, making it a sales-led, project-scoped model.
