What Sizekick does
Sizekick is a Munich-based B2B SaaS company, founded in summer 2022, that uses artificial intelligence and computer vision to deliver clothing size recommendations for fashion e-commerce. Its core product combines two user-facing modules — BodyFinder, an AI-driven body-shape selection tool, and BodyScanner, a video-based smartphone body measurement solution — integrated into partner online stores via a widget known as the 'Sizekick Button.' Underlying the product is a deep-learning model trained on Hohenstein's large 3D body scan database, supplemented by product-level feedback loops from each integration that continuously improve recommendation accuracy.
The company monetizes through recurring SaaS fees paid by fashion brands, retailers, and marketplaces, with potential usage-based components; the sizing solution is free for end consumers. Distribution combines direct enterprise field sales, a self-serve Shopify App Store listing, and channel-led go-to-market via strategic partner Hohenstein, which also acts as the company's anchor investor (€1.3M seed, November 2022). The customer base spans premium womenswear, outdoor, sportswear, multi-brand retailers, plus-size, lingerie, and evening-wear segments across Germany, Switzerland, the US, and Sweden, with a recent vertical expansion into workwear through a partnership with Elis.
The founding team — CTO Jake Lydon and CEO David Oldeen — previously built the sizing AI at Presize prior to its acquisition by Meta in 2022, providing deep domain expertise in computer vision and apparel fit. Sizekick maintains 100% GDPR-compliant data processing with automatic anonymization of biometric inputs, a meaningful differentiator in privacy-sensitive European markets. The company operates from the TUM/UnternehmerTUM Venture Lab Software/AI ecosystem in Munich and serves a globally distributed customer base, though revenue figures are not publicly disclosed.

Sizekick competitors and assessment
Company assessmentDirect peers
- Reactive Reality: European (Austrian) fashion-tech company offering AI-driven size recommendation and photorealistic virtual fitting for apparel brands. Closest direct European-headquartered competitor and most comparable on product positioning.
- True Fit: Largest dedicated fashion sizing/fit recommendation platform, serving thousands of footwear and apparel brands and retailers globally with personalization and sizing AI. The closest scaled direct competitor to Sizekick in target customer and product.
- Style.me: Virtual fitting room and size recommendation platform for fashion e-commerce, providing try-on visualization alongside size guidance. Comparable target market and product surface as Sizekick, though more weighted to visualization.
- 3DLOOK: AI body scanning and measurement company offering smartphone-based and scanner-based body data capture for apparel, uniform, and health verticals. Directly comparable technology stack and customer profile to Sizekick's BodyScanner.
- Bold Metrics: AI body measurement and fit-prediction platform serving apparel brands and uniform/workwear companies; uses statistical models rather than computer vision but targets the same sizing-and-fit recommendation use case as Sizekick.
- Fit Analytics (Snap): Size-and-fit recommendation platform acquired by Snap Inc. in 2021; Sizekick's own website explicitly targets Fit Analytics customers for upgrade. Same product category, same target buyer, same core technology approach.
- Vue.ai: Retail AI platform offering size recommendation, visual search, and personalization for fashion e-commerce. Overlaps with Sizekick on size-and-fit recommendation while bundling a broader merchandising AI suite.
- Metail: UK-based fashion AI company offering body-modeling and size recommendation for apparel retailers; pioneered early 3D body-driven fit guidance. Direct comparable on use case and target customers (fashion e-commerce brands).
Others
- Hohenstein: Strategic investor, exclusive data partner, and channel ally of Sizekick, providing 3D body scan databases, fit analysis, and brand introductions. Included as a key ecosystem relationship rather than a competitor; comparable in that Hohenstein operates in the broader sizing/fit consulting space.
Broad incumbents
- Meta Platforms (Presize): Acquired Presize — Sizekick's founders' prior company — in 2022 and retains that sizing-AI team and technology. While Meta does not currently sell a standalone sizing SaaS, it could bundle the capability across Instagram/Facebook Shopping, posing a structural platform risk to independent vendors like Sizekick.
