From Side Project to Enterprise Sales: How QuestDB Built Their Go-to-Market Motion

Before QuestDB became a venture-backed database company serving billion-dollar enterprises, it was a passion project built to solve a specific problem. In a recent episode of Category Visionaries, Nicolas Hourcard revealed how they transformed a side project into a commercial success story.

The Origins: Finding Product-Market Fit in Finance

The seeds of QuestDB were planted in an unlikely place – an investment bank. “At Rothschild, which is an investment bank, I was part of a new team, a bit like a startup, essentially very small team within a larger bank. And that team was focused on data and analytics,” Nicolas explains. “Essentially all the data we’re analyzing was time series data. So that’s where my love for time series started.”

This experience proved crucial when Nicolas met his future co-founder, who “was building QuestDB on the side sort of passion project.” The project had already undergone real-world testing: “getting feedback from the places they worked at, which was great. So we could iterate very fast, but we didn’t get a lot of pull from open source communities yet.”

The Y Combinator Inflection Point

The early days were challenging. “The first months were probably the toughest,” Nicolas recalls. London-based VCs were skeptical, but everything changed after they got into Y Combinator. “We applied to YC, we got into YC and then things became a lot easier for us.”

Finding Their Competitive Edge

A crucial realization shaped their go-to-market strategy. Rather than trying to match competitors feature-for-feature, they focused on excellence in a specific niche. “We cannot win by just catching up on features. Even if we match all those features and it takes us five years, we’re not going to win,” Nicolas shares. Instead, they chose to “become ten x better than the competition on a much narrower set of use cases.”

The Path to Enterprise Sales

Their enterprise journey began organically. “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 explains. These consistent requests – particularly around distributed setups and security features – helped them identify their ideal enterprise customers.

Today, they’re selling to “pretty large companies, listed companies worth more than $50 billion market caps,” but they maintain their technical-first approach. “Having too many salespeople on those calls wouldn’t be that beneficial. Sometimes I bring my co-founder CTO, sometimes we bring engineers as well in the calls because the questions are highly technical.”

Building the Team Strategically

Their approach to scaling follows Y Combinator’s advice: “Hire more as you make more AR.” As Nicolas describes it, “We hire when we feel like we desperately need to hire more. It’s not like, oh, I’m feeling a bit stretched, maybe we should hire a bit more here and there. It’s like, I cannot function like this anymore.”

The Technical Marketing Engine

QuestDB’s marketing strategy remains deeply technical. “We try to do super authentic technical content that is going to resonate with a technical audience,” Nicolas explains. This includes detailed benchmarks and engineering stories that might seem “very technical, a bit nerdy, but that’s what makes developers click sometimes.”

Their marketing team structure reflects this philosophy: “There is no like head of marketing or anything like this, just developers writing about the code they produce.”

Looking Ahead

QuestDB’s near-term goal is clear: “To become the go to database for storing financial market data and IoT sensor data at a petabyte scale.” But their long-term vision is even more ambitious, aiming to support “more types, arrays, vector embeddings” and power “virtually any application in Genai and other fields.”

Their journey from side project to enterprise database offers valuable lessons for technical founders. By maintaining their technical authenticity, focusing on specific use cases where they could excel, and growing deliberately based on customer demand, QuestDB has built a sustainable path to market that doesn’t compromise their engineering-driven culture.
