Fermat

Fermat is a generative AI platform for fashion and luxury design teams. Its toolbox covers concept, development, production and content work: turning apparel sketches into photo-realistic images, generating variations of a design's sleeves, hems, necklines, fit and length, applying materials and fabrics, and visualizing garments on virtual models. Adjacent modules address graphics and prints (extracting motifs and patterns from references such as vintage textiles or archival prints, editing colors, scale and repeats, and rendering motifs onto modeled garments), e-commerce and campaign photography (extracting garments from styled imagery into flat-lays, dressing models, and generating multiple PDP angles from one input), and home decor and product/space rendering.

The product is organized around an AI toolbox and "Atelier" with more than 50 tools, sketch-to-3D-render conversion, custom styles trained from moodboards, products and visual references, an asset library of team-generated and uploaded images, bulk processing and automations, and shared team workspaces that preserve iterations and versions for handoff. Enterprise features include SSO and on-prem deployment, admin control over teams and roles, model opt-outs, GDPR compliance, usage analytics on AI adoption, agentic AI trained on a brand archive, white labeling, custom subdomain deployment, batch processing and API access, and a no-code tool editor. The company states content ownership remains with the customer, that generations stay private and that its models do not train on customer data, and it cites SOC Type I and SOC 2 Type II. Fermat publishes documentation covering a tool catalogue for apparel and accessories, photoshooting and styling, graphics and prints, custom styles, moodboards, objects, materials and fabrics, faces and people, and an asset library, plus a Fermat capture feature.

Business model

Software-as-a-service sold on a credit-based subscription, with self-serve individual and team tiers alongside a contracted enterprise offering that adds security, administration, customization and services such as in-person workshops at design headquarters.

Recurring subscriptions billed monthly or annually with a discount for annual commitment: Fermat Pro at $30/month ($330/year) with 150 credits per month for individuals and freelancers; Fermat Studio at $250/month ($2,700/year) with 500 credits per month, team access and unlimited users; and Fermat Enterprise priced on request with a custom credit allowance. A free plan includes 1 credit. Each image generation costs 1 credit and each video generation 4 credits, with additional credits purchasable.

Traction

Published customer references include Tendam, which reported a shortened design development timeline, and Children's Apparel Network, which described converting sketches into renders and flat drawings in place of manual work and pre-production photography. ASOS announced in February 2026 that it would use Fermat to upskill all of its designers in generative AI, and New Look was reported in mid-2026 to have adopted the platform for buying and design teams. The company claims cuts of 75-80% in core design task time, including sketch-to-render in 15 minutes versus 45, material application in 15 minutes versus 2 hours, and on-model outfit visualization in 15 minutes versus 2 days.

Latest developments

Recent activity centers on enterprise retail deployments and community publishing: an ASOS program to upskill all designers in generative AI announced in February 2026, a New Look rollout to buying and design teams reported in June 2026, and a steady cadence of ambassador and in-house campaign posts through early 2026.
