Fit Collective (London) raised $3.9M to correct inconsistent sizing during the production phase using AI.

London's Fit Collective and Munich's Sizekick have each closed funding rounds that reflect growing investor conviction that AI can solve what decades of standardisation efforts have not.

What happened

Fit Collective, based in London, raised $3.9 million to address sizing inconsistency at its source: the production stage. Rather than waiting for garments to reach consumers before discovering fit problems, the company's AI intervenes during manufacturing, identifying and correcting size deviations before items leave the factory. The approach targets the upstream root cause of a problem that has long been treated only downstream.

Sizekick, headquartered in Munich, closed a $1.3 million round to tackle the same crisis from the consumer-facing end. Its platform combines artificial intelligence with computer vision to help shoppers identify the right size before completing a purchase, with the explicit goal of reducing the volume of returns that flow back through retailer logistics networks.

Why it matters

Fit is consistently cited as the primary driver of fashion returns, a category that generates significant financial and environmental costs across the industry. Returned garments travel back through warehouses, are often discounted or destroyed, and generate carbon emissions at every step. The problem is compounded by the absence of a universal sizing standard: a size 12 in one brand can differ materially from a size 12 in another, even within the same country.

The two startups represent a complementary architecture for addressing this gap. Fit Collective's production-stage correction reduces the number of non-conforming garments that enter the market in the first place, while Sizekick's consumer-facing tool reduces the likelihood that a correctly sized garment is ordered in the wrong size. Together, their approaches span the full journey from factory floor to checkout.

The European AI fashion tech landscape

Both rounds underscore the momentum building around AI fashion tech in Europe, with the United Kingdom and Germany emerging as active hubs. Venture capital interest in the segment has grown as retailers face mounting pressure to cut return rates — both for margin reasons and in response to tightening sustainability regulation across the European Union. Startups that can demonstrate measurable reductions in returns or production waste are increasingly attractive to investors focused on the intersection of technology and fashion.

What to watch next

The key question for both companies is whether their tools can demonstrate return-rate reductions at scale across diverse retail partners and garment categories. Fit Collective's model will be tested by its ability to integrate with manufacturers operating across different production systems and geographies.

Sizekick's traction will depend on consumer adoption of its computer vision sizing tool and on retailer willingness to embed it at the point of sale. Broader industry uptake of AI-driven sizing solutions — and the regulatory environment around fashion sustainability in the EU — will shape the commercial runway for both.
