As answered by people managing DeveloperToolStack and SpecForm OS.
SpecForm OS's answer:
Morchen (Founder) spent 6 years teaching fashion design and development at Universities and watched talented designers hit the same wall: not creativity, not pattern cutting, but the tech pack. The £500-2,000 freelance cost per style killed independent brands before they started. Built SpecForm OS to remove that gatekeeping.
SpecForm OS's answer:
Only tool that turns a garment photo into a factory-ready tech pack in minutes, with human-in-the-loop editing before export. Competitors make you draw flats manually or wait weeks for freelancers.
SpecForm OS's answer:
Speed and price. Techpacker starts at $49/mo and still requires manual flat drawing. Centric PLM is enterprise-only with 6-month onboarding. SpecForm OS: upload photo, AI generates everything, you edit, export PDF. £15/mo, 5 minutes.
SpecForm OS's answer:
Independent fashion designers and small brands doing 10-40 styles per year. They can't afford £2,000 freelance tech packs or enterprise PLM software, but factories demand professional documentation before cutting samples.
SpecForm OS's answer:
ASOS inbound 85-brand pipeline including NovaSupplier (Portuguese manufacturer marketplace)
SpecForm OS's answer:
SpecForm OS is built with AI core trained on professional fashion construction knowledge and computer vision to interpret garment and auto-generates precision technical packs.
