Here's the one-hundred fiftieth (!!) issue of COSS Weekly, the global commercial open source (COSS) company category newsletter, brought to you every weekend by the team at OSS Capital, creators and stewards of COSS Community and Open Core Summit.

We deliver only the most fresh 😋 news from the previous week in COSS across: Funding, Content, Jobs, Liquidity and $COSS (Public Markets).

Last week saw $53.5M in funding announcements from Pulumi, CrabNebula, Kestra, and Kedify, the 5th Anniversary of OSS Capital, important AI conversations, and major project milestones!
