About

Most AI products hand you a coworker on day one and hope you trust it. Sauna is the coworker you raise: it starts by learning how you work, earns autonomy task by task, and ends up running hours of work on its own while you keep taste, review, and the final say. Wordware is the ~20-person team behind it, backed by Spark Capital, Felicis, and Y Combinator with a $30M seed, the largest in YC history. We build from a San Francisco office in the shadow of the Golden Gate Bridge, and we work absurdly hard because we can see and feel the outcome every day.

Founders

  • Filip Kozera· Founder

    Cofounder and CEO at Wordware -- an IDE for Natural Language Programming and Agent Orchestration. Previously I cofounded and exited KRISTALIC, which tried to augment the human memory. Before that, I studied Deep Learning at Cambridge. The most interesting fact about me outside of work is that I travelled to 103 countries and was part of multiple high-altitude mountaineering expeditions and rescue operations in Kyrgyzstan and Nepal. I also do sailing, paragliding, kitesurfing and boxing.
