HIBT Lab! Gro Intelligence: Sara Menker

Growing up in Ethiopia in the 1980s and ‘90s, Sara Menker saw the devastating effects of drought and famine firsthand. Later as a commodities trader on Wall Street, Sara realized that a major driver of food insecurity around the world was a lack of good data to predict weather events, crop yields, a

Episode Summary

Executive Summary: Sarah Menker explains how growing up amid scarcity in Ethiopia and working in commodities at Morgan Stanley led her to found GROW Intelligence, a company that turns massive global agricultural and climate data into forecasts for food supply, demand, pricing, and climate risk. The conversation links food insecurity to access, affordability, climate shocks, fertilizer shortages, and geopolitics, showing how data can help governments, businesses, and aid groups plan ahead.

Main Topics: From scarcity in Ethiopia to a systems mindset (Priority: 5/5): Menker describes how childhood in Ethiopia during a period of state control and limited resources shaped her perspective on abundance, essentials, and risk. Wall Street, commodities, and the origin of the idea (Priority: 5/5): Her work in natural gas and commodities exposed how prices are driven by supply, demand, weather, and data—leading her to see a gap in agricultural forecasting. Why agriculture is harder to model than energy (Priority: 5/5): She contrasts a single commodity like natural gas with tens of thousands of agricultural products, each with different biology, fragmented supply, and poor data infrastructure. GROW Intelligence’s data and AI platform (Priority: 5/5): The company ingests data from tens of thousands of sources in many formats and languages, then standardizes it into predictive models used by traders, governments, and suppliers. Global food insecurity and structural shocks (Priority: 5/5): Menker argues the Russia-Ukraine war intensified an already-existing crisis driven by China’s grain demand shift, COVID-era disruptions, and climate-related supply shocks. Fertilizer as a looming crisis (Priority: 5/5): She highlights fertilizer, especially nitrogen-based fertilizer tied to natural gas, as a major near-term threat to global yields and food availability. Climate adaptation and land suitability (Priority: 4/5): GROW’s climate indices and forward-looking models help users assess drought, flood, heat, cyclone, and long-term land suitability under climate change.

Key Arguments: Food insecurity is primarily an access and affordability problem, not simply a production problem. Agricultural markets lack the data infrastructure needed to answer basic investment and policy questions. Agriculture is vastly more complex than energy because it includes many crops, many geographies, and fragmented production. The Russia-Ukraine war did not create the food crisis; it accelerated a crisis already underway due to structural market shifts. Fertilizer shortages are a major threat because nitrogen fertilizer depends heavily on natural gas and high energy prices. Predictive analytics can help governments, companies, and aid organizations move from reacting to planning. Climate change will shift where crops can be profitably grown, affecting investment, supply chains, and food security.

Data Points: Founding year of GROW Intelligence: 2014 - Menker founded the company after leaving Morgan Stanley. Years at Morgan Stanley before leaving: 8 years - She spent roughly eight years on Wall Street before pursuing GROW. Time spent defining the business after leaving: 2012-2014 - She quit in 2012 and spent two years shaping the company before launching. Data sources ingested by GROW: 50,000 sources - The platform collects agricultural and climate data from around the world. Modeling frameworks: 28 - GROW uses 28 modeling frameworks to generate forecasts. Unique models generated: 2 million - The frameworks scale into millions of crop- and region-specific models. Company funding raised: more than $125 million - Menker notes GROW has raised over this amount as of the current year. U.S. food waste: 40% - Referenced when discussing food insecurity and availability. Forecast lead time vs USDA in the U.S.: 4 to 6 months ahead, 98% to 99% accuracy - Menker says GROW can outperform or anticipate public estimates in some markets. Forecast lead time in some emerging markets: 1 to 2 years - She says GROW often provides earlier insight in places like India, Russia, China, and Africa. Fertilizer cost share from natural gas: 70% to 90% - Natural gas makes up most of the cost of nitrogen fertilizer production. Estimated calorie reduction from nitrogen fertilizer problem: 216 trillion calories - Menker says a reduction in fertilizer use could cut global food output by this amount. Sudan basket price increase since start of 2020: 1,900% - She cites the cost increase for basic foods in local currency. Syria basket price increase since start of 2020: 700% - Used to illustrate severity of food inflation. Ethiopia basket price increase since start of 2020: 175% - Shows local food inflation in her home country. Argentina basket price increase since start of 2020: 300% - Another example of widespread food inflation. United States basket price increase since start of 2020: 67% - Even wealthy countries are facing major food price increases. Europe basket price increase since start of 2020: 80% - Demonstrates broad-based global inflation in food costs.

Pivotal Quotes: "Food insecurity is about access and affordability." — Sarah Menker: She defines the core issue after discussing global food abundance and waste. "The Russia-Ukraine war didn't start a food security crisis. It added fuel to an already long-burning fire." — Sarah Menker: She explains the crisis as structural, not caused solely by the war. "We're just not going to solve these big food security challenges at some point; we were like trying to fix a system we didn't even understand." — Sarah Menker: She describes the realization that pushed her toward building GROW.

Implications: The episode suggests food markets now require real-time, data-driven planning across climate, fertilizer, geopolitics, and logistics. Businesses and governments that use predictive analytics may better manage shortages, prices, and climate migration of crops.
