We build software people love to use
We're a small, intentional company that combines thoughtful design with solid engineering — building for ourselves and for our clients.
Who we are
Two founders,
one mission
65FN LLC was founded by Nicola and Felix — two software engineers based in Castelldefels, Barcelona. With backgrounds in computer science and a shared drive for quality, we started the company to build software the way we think it should be built.
We handle the full product lifecycle: from concept and design through development, launch, and ongoing iteration. Our core focus is iOS and Android applications, backed by robust cloud infrastructure.
