OPEN SOURCE
Based on the interview with Lars Hermann (former VP, Partner Ecosystem at MongoDB & Red Hat)
Lars Herrmann is a builder of successful products, businesses and teams. With 30 years experience in enterprise software, his passion is in creating innovative business models, unlocking exponential growth with the multiplier effects of Open Source communities and partner ecosystems, and helping companies of any size define and execute the best product and GTM strategy at any inflection point.
We recorded this conversation on a sunny Friday afternoon via Zoom — Pretiosum Head of Platform, Anna dialling in from London, and Lars from Boston. As more founders integrate open source into their go-to-market (GTM) strategies, we sat down with Lars, to unpack what works, what doesn’t, and the pitfalls to avoid.
The Open Source Growth Playbook
Open source has evolved from a developer passion project to a strategic GTM motion. But not every startup should adopt it. Lars breaks it down into a simple decision framework:
If your product is infrastructure-related or developer-facing, open source can accelerate adoption.
If your target user writes code and benefits from ecosystem collaboration, it’s a strong fit.
If integrations with other platforms are key to your success, open source lowers the barrier to entry.
If you’re selling to business buyers who don’t code, open source likely won’t drive conversion.
Balancing Speed and Risk: The Cost of Free
Many startups see open source as a cost-saving shortcut. That’s a mistake. “Open source is not free,” Lars warns. Some of the biggest pitfalls include:
✅ Legal & Compliance Risks – Founders often overlook licensing issues, which can create major roadblocks during fundraising or acquisition.
✅ Technical Debt – Relying on open source without understanding versioning and compatibility can create costly engineering problems.
✅ Security & Patents – Some projects come with hidden legal risks, including potential litigation from patent trolls.
✅ Hidden Infrastructure Costs – Open source may shift costs to users, but at scale, hosting and maintaining software can become expensive.
The key takeaway? Don’t treat open source as a cost-cutting tool—use it strategically to drive adoption.
Monetization: Turning Free Users into Paying Customers
The reality is that only 1-5% of open-source users convert to paid customers. So how do you improve monetization rates?
🔹 Don’t just offer “free vs. paid” tiers. Give users multiple upgrade paths—think freemium, usage-based pricing, or enterprise add-ons.
🔹 Understand your users’ journey. People move from curiosity → experimentation → deployment. Attach pricing to the right stage.
🔹 Leverage Open Source + Cloud. Many regulated industries (like finance) can’t use SaaS, but open source allows them to adopt your tech.
🔹 Data is your friend. Don’t just let users download and disappear. Capture insights on usage patterns and engagement to drive conversion.
Enterprise Partnerships: The Smart GTM Hack
Startups often struggle to land big enterprise contracts. A partnership strategy can help.
How do you pick the right partner?
✅ Look at your ideal customer’s tech stack. What other tools do they already use? ✅ Where do your customers spend time? Developer forums, cloud marketplaces, or enterprise ecosystems?
✅ Who already has distribution in your space? Embedding into AWS, HubSpot, or Red Hat can be a shortcut to adoption.
The right partnership gets you inside enterprises without the long procurement cycle.
Final Thoughts
Open source is a powerful tool—but it’s not a business model. Founders who see it as a GTM motion rather than a monetization strategy will build more sustainable companies.
