UK supermarket Tesco launches its first GetGo “just walk out” store, using weight sensors and AI to track purchases, in partnership with Trigo

Context & Ripple Effects
The GetGo opening is the payoff of a two-year build-out: Tesco quietly partnered with Israeli startup Trigo Vision back in 2019 to develop cashierless stores as Amazon's threat loomed, and Trigo raised its $22M Series A that September on exactly this pitch — selling supermarkets cameras, sensors, and software so they could run Amazon Go-style stores of their own.
Amazon proved the format in Seattle with its original checkout-less food store, but Tesco is now the first major non-US grocer to ship it at scale with an independent vendor — weeks before rival Sainsbury's answered by becoming the first known customer for Amazon's Just Walk Out tech outside the US.
First-order effects
- Tesco shoppers at the GetGo location no longer pass through a checkout; weight sensors and AI track baskets, shifting labor from tills to floor and putting Tesco ahead of Sainsbury's in UK checkout-free deployment.
- Trigo converts its 2019 partnership into a flagship reference installation, validating its vendor model against Amazon's competing Just Walk Out offering.
Second-order effects
- Sainsbury's choice of Amazon's system rather than building one forces a two-vendor race in UK grocery, where chains must pick between Amazon's tech (and its data relationship) or independents like Trigo — pressure that extends to Aldi and other Trigo clients.
- Investor appetite follows proof of deployment: with a live store running under its name, Trigo is positioned for larger rounds like the $100M raise that followed.
Third-order effects
- If both routes scale, UK grocery splits into camps defined by who owns the perception stack — retailers renting Amazon's platform versus those backing independent vendors — shaping how much shopper data stays inside each chain rather than flowing to Amazon.
- Checkout-free formats move from experiment to standard grocery infrastructure, making shelf-attached sensing and AI a baseline capital cost for large supermarkets.
The trend: Cashierless retail is spreading beyond Amazon's own stores as major grocers adopt third-party computer-vision checkout, splitting into Amazon-platform and independent-vendor camps along the way.
