Sweetgreen Infinite Kitchen — automated salad makeline, deployed across 18+ new restaurants in fiscal 2025

NA-USA

Content

Sweetgreen’s Infinite Kitchen is an automated bowl/salad makeline that uses robotics + AI/ML to assemble customer orders. The system originated from Sweetgreen’s 2021 acquisition of Spyce (an MIT-spinout automated kitchen company; note: Sweetgreen earlier acquired Galley in 2019 for meal-kit logistics, but Infinite Kitchen is the Spyce technology line).

Sweetgreen reported in 2025:

• Plans for 18 of 37 net new restaurant openings in fiscal 2025 to feature Infinite Kitchen, plus 7–9 new units and 2–4 retrofits in earlier 2024 plans.
• Q3 2025 earnings release updates: at least 25 new Infinite Kitchens planned for 2025.
• September 2025 announcement: Sweetgreen is selling the Infinite Kitchen business (Spyce) to Wonder for $186.4M, while retaining the right to deploy the technology in its own restaurants “with even greater [speed]”.

The Infinite Kitchen is not a consumer-facing conversational AI surface; it is in-store automation. It is included in the taxonomy because it is the largest deployed AI/robotics system in US fast-casual restaurant consumption as of mid-2026.

What this unit is doing in the taxonomy

The consumer-facing tag in the schema is loose here: Infinite Kitchen is behind the counter. It is included because the consumer experiences the AI through the output (the bowl that arrives) and because the technology question (AI in restaurant food assembly) is structurally parallel to consumer AI.

Why it matters for talks

• Documents the robotics/automation layer of consumer-facing AI in US food — distinct from the conversational/LLM layer.
• The Spyce → Sweetgreen → Wonder divestment trajectory is a teachable pattern on strategic refocusing in restaurant AI.
• 18 new units in one fiscal year is meaningful scale for restaurant automation.

Critical context the unit does not sanitise

• Restaurant automation has a labour displacement dimension — Sweetgreen has not publicly committed to a no-layoffs policy tied to Infinite Kitchen deployment.
• The September 2025 sale to Wonder is itself a strategic signal: Sweetgreen is exiting the technology business to focus on the restaurant business, while licensing back the technology. This is a common pattern but worth surfacing.
