About twentyfour26
Summary
twentyfour26 runs an autonomous CNC machining cell in San Francisco that delivers same-day metal parts from a STEP file upload. Hardware teams upload a design, the software checks machinability, generates a machining program, and cuts the part on-site, replacing the days-long back-and-forth of traditional machine shops. The service targets rapid prototyping by constraining the cell to a fixed envelope, materials, and tooling so accepted jobs move immediately from quote to cut.
Business model
Per-job quotes generated from uploaded STEP files
Go-to-market
Hardware teams and product developers start self-serve by uploading a STEP file directly on the website to get an instant machinability check and quote.
