"We expected a proposal and a powerpoint presentation about what would be built. Instead we received a functional prototype with our data in it!  Heltoni - Unimed - Long and tiring meetings, informal processes and the risk of human errors and the lack of visibility on the costs of the projects. These were all difficulties that were solved by the solution that LEF created very quickly and according to our needs. "

LEF develops and modernizes business-critical applications using Thinkwise low-code technology. We help organizations replace outdated systems, integrate processes, and scale with confidence — delivering solutions that evolve as business needs change. Our team combines deep technical expertise with a pragmatic, results-driven approach. We work closely with clients to understand their operations, identify inefficiencies, and translate them into agile, future-proof applications. By focusing on business outcomes rather than technology alone, we ensure every project delivers measurable value. 

Based in Brazil, we serve both local organizations and existing Thinkwise customers worldwide. This dual focus means we can adapt to different market realities while maintaining a consistent level of quality, speed, and flexibility. Whether the goal is to modernize a complex legacy environment, implement new functionality, or extend an existing Thinkwise application, our approach is always tailored — never templated. With LEF, clients gain a partner who not only understands the technical possibilities of Thinkwise but also how to align them with strategic business goals. Our courage to challenge assumptions and our commitment to excellence make us a trusted partner for organizations ready to take the next step in their digital evolution.
