Company Overview
About Guac
Guac is a United States-based AI demand forecasting platform for grocery retailers — backed by Y Combinator with $2.3 million in seed funding in December 2023 from 1984 Ventures, Y Combinator, Collaborative Fund, and angel investors from Instacart, Roblox, Jane Street, and Citadel Securities — providing grocery chains, delivery companies, and supermarkets across North America, Europe, and the Middle East with machine learning-powered daily sales predictions that achieve 0.95 unit mean absolute error (MAE) average forecast accuracy, delivering 38% food waste reduction for a 300-location supermarket chain customer. Founded by Euro Wang and Jack Solomon, Guac applies unconventional data signals (sports betting odds, weather forecasts, local event calendars) to grocery demand prediction where traditional moving-average forecasting fails.
Business Model & Competitive Advantage
Guac's grocery demand forecasting platform addresses the inventory accuracy problem that causes both food waste and stockouts: a grocery store stocking fresh produce, meat, and prepared foods makes daily ordering decisions across 5,000-20,000 SKUs — ordering too much generates food waste (fresh items spoil) while ordering too little creates stockouts that frustrate customers and lose sales. Traditional demand forecasting uses historical sales averages, seasonal trends, and promotional calendars — but misses the external signals that actually drive grocery demand variability. Guac's ML models incorporate unconventional demand signals: NFL game days drive chicken wing sales spikes; weather forecasts predict BBQ demand increases; local events (concerts, marathons, graduations) shift shopping patterns. By integrating these external signals with historical sales data, Guac's forecasting achieves accuracy levels that reduce the inventory buffers grocers maintain to avoid stockouts — translating directly to less food waste and improved margin on perishable categories.
Competitive Landscape 2025–2026
In 2025, Guac competes in the grocery demand forecasting, retail inventory optimization, and food waste reduction market with Blue Yonder (supply chain platform, $3.3B acquisition by Panasonic), Afresh Technologies (fresh food forecasting, $148M raised), and Relex Solutions (retail supply chain, $500M raised at $5B valuation) for grocery retailer AI demand forecasting and inventory optimization platform adoption. The Instacart and Roblox angel investors bring both grocery delivery market access and consumer behavioral data expertise. Jane Street and Citadel Securities' participation reflects quantitative prediction expertise applied to retail demand forecasting. Y Combinator backing connects Guac with the food technology and supply chain investment community. The 2025 strategy focuses on growing the multi-location supermarket chain deployments (where 38% waste reduction compounds across hundreds of stores), building the automated ordering integration for direct replenishment trigger from forecast to purchase order, and expanding the convenience store and food service operator channels for fresh inventory management.
