Filip Kozera is a Polish software engineer and entrepreneur. He is the co-founder and CEO of Wordware, a San Francisco-based artificial intelligence company that develops AI agents and tools for knowledge workers. Wordware participated in Y Combinator's Summer 2024 batch and raised a $30 million seed round, reported as one of the largest seed rounds in Y Combinator's history.[1]
Career
Prior to founding Wordware, Kozera was the co-founder and CEO of Golem Network, a project in decentralized computing that he helped establish around 2016. His technical background includes experience in software architecture, distributed systems, Python, and blockchain technology.[2]
Kozera founded Wordware in 2023 with the premise that natural language would become the next programming language. The company's initial product was a development platform that aimed to make AI development accessible to non-programmers, drawing a parallel between how spreadsheet software democratized data analytics for hundreds of millions of users beyond the smaller population of professional software developers.[3]
The company joined Y Combinator's Summer 2024 batch and subsequently raised $30 million in seed funding backed by Spark Capital, Felicis, and Y Combinator.[4] The round was reportedly closed in seven days.[5] Wordware's launch also achieved the top position on Product Hunt at the time.[6]
Wordware's main product evolved into Sauna, described by the company as an AI workspace for professionals. Sauna functions as an AI assistant that connects, with user permission, to tools such as Gmail, Calendar, and Slack to gather context and assist users in completing work tasks. The company categorizes its work in the areas of AIOps, artificial intelligence, developer tools, and infrastructure.[4]
In October 2025, Kozera appeared on Sequoia Capital's Training Data podcast, where he discussed his vision for "word artisans" — knowledge workers who use AI to amplify their creative impact by working across multiple abstraction layers while preserving human creative control.[3]
