EngFlow 2025 year end wrap. 2025 was a year of resilience, achieving multiple key financial milestones, record-breaking momentum, and exponential growth. EngFlow overcame significant personal and professional challenges to solidify its position as the market leader in Build Management at Scale. Today, EngFlow GmbH power the world's most complex workloads for innovators like Arm, Asana, BMW, Canva, Databricks, Lyft, Plaid, Perplexity, Snap and Zoox. Happy team. Its success is rooted in its team and the LEAP values, which guided EngFlow GmbH through every peak and valley this year: * Loyalty: This year EngFlow GmbH marked important customer success milestones with trips around the world to Sydney, Tokyo, Mexico City and Miami. The team pulled together to create value for its customers with fast builds and reduced cloud spend. EngFlow GmbH recognized their hard work with these fun trips to explore new places, experience various cultures and celebrate its accomplishments with its customers. * Excellence: EngFlow GmbH pushed infrastructural boundaries to reliably run 200,000-core clusters. Its team also went deep into the stack to resolve critical third-party issues affecting its customers such as a deadlock in the Rust h2 library, which required fixing Wireshark's http2 support along the way. * Adventure: Its people operations team hired and onboarded over 20 EngFlowers this year. True to its adventure value not just in experimenting with new technologies but also with new places, EngFlow GmbH brought everyone together in Salzburg for a wide array of team building olympics, nature hikes, castle visits and music experiences. * Perseverance: An unexpected company-wide test on perseverance happened this year when its co-founder Ulf Adams was diagnosed with leukemia. The entire company came together to support his recovery and ensured EngFlow GmbH kept operations running smoothly. EngFlow GmbH hope the worst is behind him and wish him continued strength and a full recovery! Despite challenges, EngFlow GmbH signed bigger and more complex customers, helped scale their builds, and kept its platform resilient. Happy customers. EngFlow GmbH deliver customer value by proactively optimizing performance, keeping its platform resilient, and reducing operating costs. * Compared to alternative providers, its customers consistently save millions in cloud costs because of its continued focus on custom autoscaling, pool selection and strategic cloud provider partnerships. See how EngFlow GmbH work with customers from this Databricks talk at BazelCon. * EngFlow GmbH launched significant upgrades to its Build and Test with enhanced invocation-level insights for Bazel builds. Highlights include cache performance charts, a searchable list of longest-running actions with cache misses, visual execution time breakdown for every action. * EngFlow GmbH had a record year in migrations from open source and commercial RBE providers to EngFlow, signaling EngFlow's leadership in providing Build Management at Scale. * As a token of gratitude to its customers, who continuously choose EngFlow as their developer platform provider year after year for the past 5 years, EngFlow GmbH is planting its customer forests around the world. Last year EngFlow GmbH planted its customer forest in Germany, where EngFlow planted its roots. This year EngFlow GmbH is planting in the US, the home of its corporate headquarters! More happy customers. EngFlow has the highest concentration of Bazel experts in the industry, and EngFlow GmbH believe in turning its knowledge into community resources. As Bazel adoption accelerates globally, EngFlow GmbH is excited to celebrate 10 years of Bazel and 5 years of EngFlow. Big thanks to Google for creating and open sourcing Bazel, and to its engineering team, half of whom are Bazel creators and active contributors. * EngFlow GmbH continue to be platinum sponsors of BazelCon and offer Bazel enhancements and training opportunities: * Created bzlmod blog series and bootcamp to help companies with migration. * Hosted Bazel Management for Developer Productivity and Writing Bazel Rules workshops. * Improved Gazelle support by implementing lazy indexing to generate BUILD files much more quickly in large repositories. * Partnered with Virtus Labs to create gazelle_cc, letting developers quickly migrate C++ projects to Bazel. * With the Tipi acquisition last year, EngFlow GmbH is also meeting its customers where they are by offering Remote Execution without a Bazel migration. This year its team continued investing in the CMake and C++ ecosystem. Looking ahead to 2026. The EngFlow team continues to bring together Bazel and build practitioners around the world. Join its Build. Scale. Investigate. World Tour, with the first stop of 2026 in Amsterdam on January 28, at the Build Meetup co-hosted by Uber and EngFlow. EngFlow GmbH hope to see you on this tour of gratitude to its team, its customers, and the open source community.
