Chama is a game-changing technology scale-up. Millions of people benefit from the company’s disruptive business model. Chama’s app enables households to order home-delivered gas cylinders with their smartphones. The new Chief Technology Officer (CTO) scales Chama’s engineering and product teams to grow the business in Brazil and beyond.


Most households in Brazil rely on bottled gas for cooking and hot water use. For cylinder replacement, they depend on a nontransparent market with high prices, slow delivery and dangerously installed bottles by clandestine dealers. Chama brings much-needed price and quality transparency. They make ordering gas cheaper, faster and safer.

Chama’s app gives consumers an overview of all accredited resellers delivering in their area, including prices, delivery times and user ratings. The company currently serves 1.4 million households in Sao Paolo, Porto Alegre, Belo Horizonte, and Curitiba.

Chama grows with 10 to 20 percent month-over-month, and has secured a substantial long-term investment to continue its extraordinary growth trajectory. First focus is conquering Brazil. Next step is entering other major markets in Latin and South America, Africa and Asia.

“The CTO is key in realizing our growth ambitions. As a company that revolves around technology, maturing our product eco-system and DevOps organization is critical for our future success.” – Marijn van de Ven, Founder and CEO
