We are Sólides, the only Brazilian technology company specializing in Integrated People Management with Behavioral Intelligence. Our platform is \#completelytrue, offering HR and Personnel Department solutions designed for all businesses across Brazil. In 2022, our story gained even greater momentum! We received the largest investment ever made in an HR Tech in Latin America — BRL 530 million, led by Warburg Pincus — and acquired Tangerino. In 2024, the acquisition of Folha de Pagamento Digital solidified our position as the one-stop-shop for SMBs, while our merger with RHGestor reinforced our commitment to making strategic people management accessible to all companies. Today, with over 30,000 customers and eight million lives impacted, we lead the high-growth enterprise sector in Brazil. To reach where no one else has, our values serve as our compass: we are courageous enough to be different, strong enough to achieve extraordinary results, experts in people, and passionate about our customers. If you too are driven by dreams, results, and people, join us — Sólides is your place!
