Solar Electric Power Generation São Paulo, São Paulo 51–200 employees Founded 2019 Privately Held

77Sol operates a B2B SaaS marketplace for Brazil's solar installation market, connecting over 30,000 integrators to lead flow and financing. The platform originates R$2B+ in monthly credit simulations and R$1B+ in solar proposals. Stack is PHP/Laravel + MySQL with Node.js workers (RabbitMQ, SQS), BI tools (Power BI, Tableau, QuickSight), and payment integration — classic marketplace infrastructure. Hiring velocity is accelerating, but the mix reveals a sales-operations bottleneck: 6 sales roles against 2 engineering, with projects focused on CRM discipline, lead qualification, and commercial process optimization, not product features. This suggests growth is constrained by commercial execution, not platform capacity.
