United StatesRetail and e-commerce2011 – ongoingStitch Fix
Algorithm-assisted personal styling
Stitch Fix built a styling business on algorithms, then lost 45% of its active clients from the 2021 peak
Problem
Stitch Fix, founded in 2011, sends customers boxes of clothing chosen for them, and they keep what they like. The model depends on picking items each client will buy, from the right warehouse and with the right stock, at a cost low enough to absorb free returns.
Approach
The company built its own algorithms to rank items for each client, match clients to stylists, assign orders to warehouses, plan inventory purchases and suggest new garment designs. Human stylists make the final selection for each box. After active clients began falling in 2022, Stitch Fix cut staff in 2022 and 2023, closed two fulfilment centres, left the UK, moved all stylists to part-time roles in 2024, and added generative AI tools for design and for an AI style assistant.
Results
Takeaway
Algorithms remained central as the business shrank; filings blamed failures to attract and keep clients and did not blame recommendation technology. Revenue returned to growth in fiscal 2026 while client numbers kept falling.

Source summaries
Stitch Fix reported that active clients fell 8.9% to about 3.80 million in July 2022 from about 4.17 million a year earlier, and revenue declined 1.4% to $2.1 billion. It describes proprietary algorithms that predict purchases, forecast demand, optimize inventory and help design apparel, and records the June 2022 restructuring that cut 15% of salaried positions.
Stitch Fix reported about 2.28 million active clients at 1 August 2026, against 2.31 million a year earlier, and says the client count has fallen year on year since fiscal 2023 because the company could not attract and keep clients. Revenue rose 6.4% in fiscal 2026 after falling 5.3% and 16.0% in the two prior years. It lists the 2022 and 2023 job cuts, the UK exit, fulfilment-centre closures and the 2024 move of all stylists to part-time.
CNBC describes how Stitch Fix fell from an $11 billion valuation to under $600 million as clients drifted away after the pandemic, and how CEO Matt Baer, hired in 2023, returned it to modest revenue growth. Baer says exiting the UK, closing two fulfilment centres and staff cuts removed more than $100 million in annual G&A costs. CNBC also reports new generative AI tools for design and styling, and analysts' doubts as the active client base kept shrinking.
