We are witnessing a significant rise in interest and investment in the developer tools sector.  Startups in this space are attracting funding as they aim to make developers’ lives easier and with the growing demand for online platforms and more companies moving to cloud operations, there is enormous potential for high growth in this area worldwide.

This area of investment has been somewhat overlooked in the past as VCs didn’t quite understand the premise nor the promise on their ROI behind tools that ease developer collaboration and developer experience.  However, this is now changing.  In this article we explore the evidence and reasons behind this surge in VC investment in developer tool startups and some of the (many) startups, scaleups and unicorns to keep an eye on.


The rise in the number of developer tool companies can be attributed to multiple factors.

Firstly, we are in an accelerating digital world.  Cloud adoption was already expanding for several years before the Covid19 pandemic, but since then, things have moved forward exponentially.  Teams were quickly forced to work remotely, securely and maintain levels of productivity.  Thus, new trends in cloud usage and security, collaboration and data sharing had to quickly take shape.  This shift has highlighted the need for robust tools that facilitate efficient and safe remote development and collaboration.

This increase in demand and necessity quickly caught the attention of VCs.  In 2021, investors contributed $37 billion to cloud and web architecture firms to support developers.  This is $17 billion more than 5 years before that in 2016[1]!  Attitudes have changed.

As interestingly pointed out in the above Business Insider article, this previous lack of popularity and understanding of developer tools among investors in the past actually presented opportunities for startups to enter and dominate this market.  These startups have capitalised on the untapped potential by offering innovative solutions and addressing the gaps in the market without too much competition from the three big players (AWS, Google Cloud and Microsoft Azure).  Investors have now begun to recognise the value and potential for the growth in the developer tool sectors, leading to increased funding and support for companies who can help developers scale more efficiently and keep up with the demand from the consumer.

As this demand increases, so will the need for tools to ease developers’ inevitable pain points to get products and services to market faster than their competitors.

From DevOps/DevSec to In-browser IDE and Documentation writing to Debugging, there are tools, and tools for tools.

And startups are a great place to look at for the latest innovations using the most recent advancements in technology.  In Y Combinator’s cohort of startups in the Winter 2023 batch open source, dev tools and AI related companies dominated.  Many of which have already received investment and attention from key players in the VC world[2].

The surge in venture capital investment in developer tool startups reflects the increasing recognition of the importance of software development and the demand for tools that facilitate efficient and innovative coding processes. VCs are keen to support startups and scaleups that provide solutions to enhance developer productivity, foster collaboration, and drive overall success. With approximately 27 million software developers worldwide and a predicted growth of more than 60% in the next 10 years, we can expect venture capitalists to play a crucial role in fuelling the growth and innovation of developer tool startups.
