ColdSnap (formerly Sigma Phase, Corp.) is a Billerica, Massachusetts hardware and frozen-confection company founded in October 2018 by Matt Fonte, whose plug-and-play countertop appliance chills and churns a single serving of premium ice cream, frozen yogurt, non-dairy dessert, frozen latte, protein shake, smoothie or frozen cocktail from a shelf-stable recyclable pod in about two minutes, with no refrigeration, plumbing or cleaning between servings. The company commercially launched in April 2024 and sells machines, pods and accessories to restaurants and bars, hotels, golf and sports clubs, colleges, senior living, car dealerships, offices, convenience stores and micro markets. Its digital surface is a Shopify-hosted commerce storefront at coldsnap.com serving a live, anonymously introspectable Storefront GraphQL API, an anonymous Model Context Protocol server at /api/mcp, a Universal Commerce Protocol (UCP) merchant profile and agentic-commerce endpoint, plus published llms.txt and agents.md agent-instruction documents.
