Eureka Case 30 min Undergrad

Three Engines, One Stove

You are Iñaki Berasategui-Olondris, 47, founder of Cocina Limpia Andes, a clean-cookstove venture you built after twelve years at Iberdrola's rural-electrification team. The pilot in Cusco worked. The 200-stove proof was clean. You now have to pick the economic engine that runs the company for the next ten years — and the three legal options on the table are genuinely different companies.

The situation

Cocina Limpia Andes designs and distributes a clean-burn LPG-plus-pellet hybrid stove for rural Andean households currently cooking on open three-stone fires. The stove cuts indoor air pollution by 78%, saves 2.4 hours/day of fuel-gathering labour, and pays back its own COGS in fuel savings inside 14 months at current pellet prices. Unit COGS landed at the factory in Lima: USD 142. Rural Peruvian highland willingness-to-pay (Cusco / Apurímac / Huancavelica): USD 28–55 cash on delivery, plus a maximum 8-month financed tail.

The gap between USD 142 and USD 55 is the case. Three economic engines have been proposed by three different sets of advisors: a Grameen-trained social-business architect (the structure Muhammad Yunus championed at Grameen Danone), a B-Corp hybrid lawyer in Madrid working with the Acumen LatAm portfolio, and a São Paulo-based CSR-program consultant who has run grant-funded distribution at scale for two consumer-goods majors. Each one wants you to sign their structure before next month's company-registration deadline.

Your job in this case: compare what the three economic engines actually do to the unit economics, model what year-5 reach and durability look like under each, and commit to a structure. The choice is not reversible cheaply — it is the legal and capital architecture you live inside for the next decade.

The decision

Which engine runs Cocina Limpia?

  • A · Grameen-style social-business (zero-dividend)
  • B · B-Corp hybrid (capped returns + impact-debt facility)
  • C · CSR grant-funded (zero customer price)
