The Business of Open Source

This week on The Business of Open Source I talked about Open Source Manifestos with Vincent Untz, CTO of Centreon. The entire conversation focused on this idea of open source manifestos, which Vincent is going to talk about at Open Source Founders Summit — and I had never heard of before. The idea to create an open source manifesto came about because internally there was a lot of frustration around Centreon’s relationship with open source. A lot of people, especially those who didn’t come from an engineering background, would routinely ask why the company invested so much in open source. At the same time, there was a feeling among the engineering team that the company’s commitment to open source — and the concrete development time spent on open source — was slipping. After creating the manifesto, the doubts about why open source mattered went away immediately — there hasn’t been a single conversation calling into question why open source matters since the manifesto was finished. Now conversations about open source are different. Externally, there’s been a huge change in conversations around open source. People say things like “Centreon is back in the game.” It’s hard to point to concrete financial results as a result of the manifesto, but there have been differences in relationships with partners for sure, and it has helped get more companies to contribute to the project. Want to see what the Centreon Open Source Manifesto looks like?

This week on The Business of Open Source, I spoke with Lukas Gentele, the CEO and co-founder of LoftLabs. Here’s some of the things we covered: There are many open source projects at LoftLabs. We talked about what the team did differently the second time round, when they’d had the experience of creating the first project under their belt, and why they continued creating additional projects after that. How they make roadmap decisions to decide what goes in the OSS versus what goes in the enterprise editionHow they thought about the benefits to the business from open sourcing vCluster, the second project they released, and whether or not the theory about how it would benefit the business ended up being correct. Whether or not open code is necessary for community building, and why. In particular, we talked about the difference in how people feel ‘ownership’ of open source projects when they contribute to them. The pros and cons of building different brands around your project, your product and your company; and of having different brands around your different projects. We talked about this a lot; LoftLabs has a different company brand from any of the products or projects, but they discovered that if the project and product do not have the same brand, people get so confused that they ultimately do not buy. If you need to figure out how to brand your project and product, you might want to work with me. If you want an opportunity to talk with other founders about branding, community building, and more, you should join us at Open Source Founders Summit May 19th and 20th in Paris. 

This week on the Business of Open Source I spoke with Daniel Jarjoura, an investor at Avolta who specializes in developer-facing companies, and who writes a newsletter on developer-facing startups and also collects data on investments in open source companies. We spoke about the overall state of investment for open source companies and specifically the state of investment in open source companies in Europe. Here’s what we talked about: Differences between venture funding for OSS companies in Europe and in NAHow open source companies were relatively stable in terms of getting venture funding, even as the entire venture funding ecosystem was in free-fall.How it might be true that European investors don’t understand open source companies, but on the other hand plenty of North American investors invest in European companies. Do developers trust open core companies? We had a discussion about whether or not open source companies have a trust problem…How important communication is for open source companies, something that I think is very true — a lot of the problems that open source companies run into when they either adopt an open core model or even when they do a license change. How founders can do a better job communicating with their VCs, including how to do a better job targeting appropriate investors. What do optimizing for in the VC relationship … and spoiler alert, that is for money. You might want a perfect VC who can make introductions, give you advice, give you money, be nice, etc. But the most important thing is the cash; focus on that. The second most important is the introductions. But advice isn’t something you should count on from VCs, and that really isn’t a VCs job, anyway. We finished the conversation with a discussion about M&A for open source companies. If you want good advice about your open source company, you might want to work with me. If you want an opportunity to talk with other founders about things like M&A for open source companies, communicating with VCs, and other topics specific to open source companies, you should join us at Open Source Founders Summit May 19th and 20th in Paris. 

This week on The Business of Open Source I spoke with Andrew Martin, CEO and founder of Control Plane. Control Plane is ultimately a consulting company, as Andrew introduced it. But the company also created and maintains KubeSec, and also has an enterprise version of Flux CD that it licenses. That gives this conversation a slightly different flavor from the usual. Here’s some of the things we talked about: The business ROI that Andrew expected to get from releasing KubeSec, and whether or not he as actually seen those expected results play outThe difference between bootstrapping a company by offering services and by offering consulting — specifically what the difference between services and consulting is. The problem with “drive-by” feature development in open source projects — when people contribute features but don’t commit to the ongoing maintenance of the projectWhy Control Plane decided to release an enterprise version of FluxCD, and how the enterprise version of Flux is differentiated from the pure open source project. Why underinvesting in marketing, especially in marketing for the open source projects, was a mistakeJoin us at Open Source Founders Summit if you want more conversations about how companies are built around open source projects, from consultancies to large corporations. 

This week on The Business of Open Source, I spoke with Misha Bragin, co-founder and CEO of NetBird. This was also the first episode I recorded in 2025, which gives you an idea of how far in advance I’m recording episodes. NetBird has an interesting origin story — it came out of an original idea to make a hardware product, but as Misha and his co-founder were starting to work out the realities of manufacturing, they realized that they would be better off building a software company. Here were some of the take aways from the conversation: Sometimes your users want to pay you! Misha explained that before there was a commercial offering, some open source users proactively reached out asking for one — because they understood that in order for the company to be viable, it needed to have revenue. Just because you get crickets at first doesn’t mean your project sucks. When NetBird’s open source project was first released, it made zero splash.The reality of working in a proprietary piece of software, you can do things quick and dirty. *Obviously you shouldn’t, but let’s face it a lot of people do. But when your code is open, it is also a part of your communication strategy! If you push out code that’s not tested or that’s not well done, you risk reputation damage even if the software works exactly as it should. Misha talked about how choosing Auth0 as an authentication service was a mistake — not because it is a bad service, but because it was not appropriate for their target audience, who are self-hosting. This is a very good reminder of how sometimes choosing the best technology for the job can backfire; you also have to take into account who the target user is and if they are going to be repelled by the choice you’re making. Struggling to figure out how to balance your project development with your product development? Need to supercharge your funnel? You might want to work with me. Want to share your knowledge and learn from your peers who are open source entrepreneurs? You should join us at Open Source Founders Summit May 19th and 20th in Paris. 

This week on The Business of Open Source, I spoke with Ty Dunn, founder of Continue.dev, which is an open source AI code assistant. We had a fabulous conversation that touched on both the AI hype wave and why open source. The first thing I’d like to touch on is why Continue.dev is open source, in other words, what business rationale Ty has for taking that route. Because he makes some great points about building an ecosystem. If building an ecosystem, and encouraging people in your community to build on top of your software, is something that is important to your for either strategic or philosophical reasons, the absolute best way to accomplish this goal is with an open source project. In the case of Continue, being open source, and allowing companies to retain control over their data, is also a differentiation in the market. There was also a phrase in the conversation that I wanted to pull out — Ty talked about monetizing “next to” the open source project. This is precisely how many of the most successful open source companies work. They have a successful open source project but monetize it in a way that is adjacent, rather than directly competing with the project. Check out the full episode for a discussion about the AI hype wave and how it intersects with open source business models. If you want more discussions about open source companies, you shouldn’t miss Open Source Founders Summit this May 19th and 20th — it’s the only event specifically designed for leadership in open source companies. And if you’re struggling with your open source strategy, you should consider working with me. 

Eileen Doody, CFO at Percona, and Karen Walker, CFO at Sysdig, share their insights into financial management in the open-source sector. They discuss the strategic role of CFOs in integrating open source into overall company strategy. The duo highlights the challenge of measuring ROI for open source investments, noting that Sysdig sees significant prospect engagement through its open-source project, Falco. They emphasize the importance of brand trust and community engagement, underlining how these elements contribute to commercial success in open-source businesses.

This week on The Business of Open Source, I spoke with Ivan Burazin, the CEO and co-founder of Daytona. First of all, Daytona was one of the sponsors of the first edition of Open Source Founders Summit, and I had a chance to meet Ivan in person at the event. So a big thank you to him for taking a risk on the first year of the event! But let’s get down to business. We talked about: Why Daytona took an open source approach, even though they originally started out with a pure commercial licensed software. The thought that went into choosing the license — this was a great discussion, because it is a question a lot of people have. Ivan walked through his thought process in choosing a license and how he thinks about difference licenses. The theory about how open source will help Daytona build their business, and the dynamics of how open source adoption leads to commercial success. The importance of technical decisions in an open source project’s growth strategy.The different stakeholders in the community, as well as in the customer community. I really liked the piece when Ivan talked about the individual motivations that people might have for getting involved in a community — instead of thinking about how you get something from the community, think about how others can get something out of the community. For example, you can have someone who wants to get into technical writing who gets that experience by writing documentation for your project. Making it easier for that to happen is in everyone’s best interest. Like this episode? Struggling with your messaging or with your conversions from open source project to commercial customers?

In a fascinating conversation with Ludovic Dubost, founder and CEO of XWiki, he shares insights from his 20 years in open source. He discusses why he chose an open source model for XWiki, emphasizing its benefits for digital sovereignty in Europe. Ludovic details how he bootstrapped the company and transitioned from support contracts to a recurring SaaS revenue model. He reveals the challenges of being small and bootstrapped, the importance of understanding the competitive landscape, and the lessons learned in balancing distribution with monetization.

This week on The Business of Open Source, I spoke with John O’Nolan, the co-founder of ghost.org. Before further ado, John is going to be one of speakers at Open Source Founders Summit 2025, so if you’d like a chance to dive deeper into any of the subjects we talked about on the podcast with him, in person, you should join us in May. There’s a lot of interesting tidbits to pull out from this conversation. First of all, I think it’s interesting that Ghost came about because Wordpress was moving away from its roots as a pure publishing tool and becoming a website builder. John, who was very involved in the Wordpress community at the time, wondered what it would look like if Wordpress went back to its roots and focused on publishing and only publishing. It’s a lesson for founders that sometimes focusing on the small niches left behind as incumbents expand can be huge opportunity. —> It’s worth noting that we recorded this podcast last fall when the drama between Wordpress and WPEngine was exceptionally hot. Ghost is organized as a non-profit, and John also talked about why he made that decision from the beginning. It came down to wanting to make a good salary at a company he had started, but without the goal of becoming fabulously wealthy as a result. We also talked about whether or not a venture-backed company can be ‘responsible’ with respect to their community; and what types of companies tend to be able to manage the tensions between the community needs and the fiduciary duty that you have if you take outside funding. We also talked about the difference in the market between the product and the project, how Ghost manages to expand in spite of not having a dedicated marketing team. We also talked about the difference between building a sustainable business and building a business that gets hockey stick very quickly as well as some of the tension between technology decisions and business decisions. If you want to talk more about these issues — and want to talk directly with John — you should come to Open Source Founders Summit May 19th and 20th, 2025.
