Reo.Dev says its Developer Knowledge Graph has passed 100 million technical profiles, which it describes as the largest collection of technical personas assembled for DevTools companies.
Built over nearly three years, the database now covers more than 30,000 technologies and 250 technical functions. It draws on data from GitHub, Stack Overflow, LinkedIn, X and other technical datasets to map engineers by what they are building and the tools they use.
The milestone reflects a broader push among software sales and marketing teams to target technical buyers based on activity data rather than job titles. Vendors in developer software have long struggled to identify the engineers most likely to influence buying decisions, especially when teams work across multiple tools, projects and open-source communities.
Reo.Dev says its system links fragmented online activity into a single view of engineering work. Rather than grouping people under labels such as backend engineer or platform architect, it aims to track the systems, frameworks and technical issues developers are actively working on.
Targeting engineers
The product is designed to help go-to-market teams build outreach lists based on current technical context, including areas such as observability, DevOps, large language model infrastructure and application performance optimisation.
"Building and selling into technical audiences has always been difficult because the right data simply didn't exist in one place," said Achintya Gupta, Co-founder and Chief Executive Officer of Reo.Dev.
Gupta gave an example of how the company views the problem.
"For example, if you're an observability platform, you don't just want to reach engineers with certain titles, you want to reach the ones actively building in the environments you support. That level of clarity was missing. With the Developer Knowledge Graph, we've brought together signals from across GitHub, Stack Overflow, LinkedIn, X and technical ecosystems to finally make that possible," said Gupta.
Founded in 2023, Reo.Dev says more than 100 DevTools companies use its platform. It is backed by Heavybit, a venture firm known for investments in developer software businesses.
Market shift
The broader market for developer-focused sales intelligence has been expanding as software suppliers look for more precise ways to identify technical decision-makers. Traditional business databases tend to rely on company records, professional profiles and seniority markers, but those methods can miss engineers whose influence stems from code contributions, technical specialisation or community activity.
For DevTools providers, that gap can be costly. Purchasing processes often involve developers, engineering managers and platform teams, yet the people evaluating products may not have titles that clearly signal buying intent.
Reo.Dev argues that a behaviour-led model more closely reflects how technical teams actually work. By tracking the technologies a developer adopts and the projects they contribute to, customers can tailor outreach to engineers whose work aligns with a product's use case, according to the company.
Gupta also highlighted the scale of the database.
"Today, we're at over 100 million developer profiles mapped across 30,000 technologies and 250+ technical functions. And this is just the beginning-the graph deepens with every developer action, making it more accurate and more powerful over time. For companies selling into technical teams, this strongly changes the odds of reaching the right audience," said Gupta.
The announcement gives Reo.Dev a numerical benchmark as it seeks to stand out in the crowded market for sales intelligence, developer data and intent tools. The company says the graph serves as the base layer for a broader product set aimed at technical go-to-market teams.
Founded by Gaurav Jain, Achintya Gupta and Piyush Agarwal, Reo.Dev has focused on the overlap between artificial intelligence systems and developer-focused commercial software. Its latest milestone underscores the growing value placed on data that reflects what engineers are doing rather than what their job titles say.
