QuestDB’s Counterintuitive Path: Why They Waited Two Years to Monetize Their Open Source Database
Most startups face intense pressure to generate revenue quickly. But in the open-source world, rushing to monetize can be a fatal mistake. In a recent episode of Category Visionaries, Nicolas Hourcard revealed why QuestDB made the bold decision to wait two years before monetizing their time series database.
The Strategic Decision to Delay
“We thought it was a requirement in order to sufficiently be focusing on building a product,” Nicolas explains. “That requires a lot of work, that base built from scratch, it’s very hard to build and it requires 100% dedication just from an engineering perspective.”
This wasn’t just about building features – it was about creating something fundamentally superior. Early venture capitalists told them to “just trying to get revenue and come back, we’ll take you seriously.” But Nicolas and his team saw a different path: “It’s really not what you should be doing at the beginning in open source. You should just put the product out there, get some users, get feedback, iterate on it.”
Building From Technical Excellence
Their focus during these two years was clear: technical excellence in a specific niche. Rather than trying to match competitors feature-for-feature, they aimed to “become ten x better than the competition on a much narrower set of use cases where most of those features are not even needed.”
This approach required intense engineering focus. Nicolas explains that the product “needs to be sufficiently good before starting to think about enterprise features to be building on top. Therefore, we spent a few years only focusing on adoption and building QUSD open source.”
Knowing When to Monetize
The decision to begin monetization came after their Series A, towards the end of 2021. But how did they know the time was right? The answer came from their users. “It was people coming to us already using quest db open source, and they’ve been asking us the same things over and over,” Nicolas shares.
These consistent requests – for features like distributed setups with multiple database instances, replication, and security features – signaled clear monetization opportunities. “Therefore we knew what we had to build. It was just about timing. When did we think that we had enough momentum and adoption so that we could start focusing on those features.”
The Validation
When they finally turned on monetization, the response validated their patient approach. “It was surprisingly good,” Nicolas recalls. They began to see patterns emerge in their customer base, leading to repeatability in their sales process. “That’s where you start to feel that hey, you’re edging into product market fit, you can just repeat things and start to see a pattern that is definitely happening for your business.”
Balancing Act
Even after beginning monetization, QuestDB maintains a careful balance between open source adoption and commercial success. “As key and as important as focusing on the revenue aspect, which is perhaps what makes building an open source company not super straightforward, because you really have to focus on the two things at the same time,” Nicolas explains. “If you have a bit too much focus one, then the other starts suffering a little bit and vice versa.”
Today, QuestDB sells to “pretty large companies, listed companies worth more than $50 billion market caps,” proving that their patient approach to monetization paid off. Their story offers a powerful lesson for open-source founders: sometimes, the path to sustainable revenue growth requires the discipline to delay monetization until your product and community are truly ready.
This counterintuitive strategy – prioritizing technical excellence and community building over immediate revenue – might seem risky. But for QuestDB, it laid the foundation for long-term success in the competitive database market.
