  • Hardware startups — design and development from concept through production
  • Small manufacturers — engineering and drafting without a full-time hire
  • Large companies — overflow capacity, R&D, or specialized project work

How it works

1
Discovery call — discuss your project, goals, and timeline at no cost.
2
Proposal — clear scope with a fixed-fee or hourly quote, no surprises.
3
Design & iteration — regular check-ins keep you in control throughout.
4
Deliverables — production-ready files, drawings, models, or physical prototypes.
