The Accidental Maintainer: Sideways Stories Into Open Source Leadership - Divya Mohan, SUSE & Natali Vlatko, Cisco

Wednesday June 25, 2025 11:00am - 11:40am MDT

Bluebird Ballroom 3C

Maintainers are responsible for technical oversight and key decisions in open source projects. Contributor ladders, found in projects like OpenTelemetry and Apache, define the journey from contributorship to maintainership. Divya Mohan and Natali Vlatko exemplify this path, having "accidentally" risen to leadership as co-chairs of the Kubernetes Documentation Special Interest Group (SIG).
But how does one stumble into leadership, and how can we make this process intentional? In their talk, Divya and Natali will share their experiences alongside insights from other leaders in the CNCF ecosystem. They will discuss how contributions—like decision-making, completing essential tasks, and sharing knowledge—cultivate a community that fosters leadership. Discover how elevated permissions can be perceived as leadership roles, how contributors who answer questions become mentors, and recognize if you’re already demonstrating these leadership qualities.
Join along to learn about the leadership tasks Divya and Natali perform as SIG co-chairs and how you can leverage your skills to lead in your project.

Funding a security initiative can be a game-changer for open source projects, but what does it really take to make it successful?

In this talk, we’ll share insights from a funded security audit in FreeBSD—how we secured support, scoped the work, engaged the community, and navigated challenges. You’ll learn how to evaluate if funding is right for your project, what to expect from the process, and how to collaborate effectively with sponsors.

Whether you're considering funding for security, sustainability, or growth, this session will equip you with practical takeaways to make it a success.

The Work No One Notices—Until It’s Missing: Scaling Open Source Community Teams - Elizabeth Barron, CHAOSS

Wednesday June 25, 2025 2:10pm - 2:50pm MDT

Bluebird Ballroom 3C

Community management in open source is often a catch-all role, with one person juggling contributor engagement, content, events, and growth. But no single individual can—or should—do it all. As projects scale, a structured, team-based approach becomes essential.

This talk introduces a four-part framework for building an effective community team:

- Community Caretakers – Foster an inclusive, welcoming space, ensuring contributors feel heard, valued, and engaged.
- Content Creators – Develop documentation, blogs, and educational materials.
- Growth Drivers – Expand the community through outreach and advocacy.
- Organizers – Handle logistics, events, and data to keep things running smoothly.

We’ll explore why many projects struggle with community management, the pitfalls of prioritizing outreach over engagement, and how a scalable team structure prevents burnout, improves retention, and ensures long-term sustainability.

Whether you're launching or scaling a project, this session provides a practical roadmap for turning fragmented community efforts into a high-impact, sustainable team.

Panel Discussion: Build a Great Business on Open Source Without Selling Your Soul - Robert Hodges, Altinity; Ann Schlemmer, Percona; Tatiana Krupenya, DBeaver

Wednesday June 25, 2025 3:05pm - 3:45pm MDT

Bluebird Ballroom 3C

A profitable business is one of the best protections for commercial open source projects and communities that depend on them. This talk draws on the experience of companies that pulled it off to explain how to do it for your own projects. We’ll discuss commercial models that actually work, giving back to the community, and gracefully collecting money for free software. We'll also touch on topics for larger projects like foundations and taking VC funding. It is possible to balance a strong belief in open source communities with making payroll every two weeks. We've done it and will share our secrets.
