Dropbox founder and CEO Drew Houston is preparing to step back after nearly 20 years leading the cloud storage company he started at age 24. In a transition announced Tuesday, Houston will move into an executive chairman role after an initial period serving as co-CEO with Ashraf Alkarmi, the company’s product chief, who has been promoted and is expected to eventually lead Dropbox on his own. The leadership change marks the end of an era for one of Silicon Valley’s best-known startup founders and one of the earliest success stories from Y Combinator to reach the public markets.
Houston built Dropbox from a simple idea born out of personal frustration, after repeatedly losing USB sticks while studying at the Massachusetts Institute of Technology. The service helped define the cloud storage category and became widely used for file sharing, collaboration and media workflows. Today, Dropbox says it has more than 18 million paying users, with especially strong adoption among professionals such as designers, architects and media workers who need to move files, photos, video and audio across devices and teams.
Despite its early prominence, Dropbox has faced pressure in a crowded market dominated by Apple, Google, Amazon and Microsoft, as well as longtime rival Box. The company reached more than $1 billion in annual revenue in 2017 and passed $2 billion four years later, but growth has slowed significantly. Revenue has been roughly flat over the past two years and fell slightly in 2025, reflecting the difficulty of sustaining momentum in subscription software as competition intensifies.
Dropbox has also struggled to match the market performance of other Y Combinator breakout companies such as Airbnb. Dropbox’s market value has remained well below its peak, even as Houston’s personal wealth, driven by his large ownership stake, has climbed into the billions. Still, the stock has held up better than many enterprise software names over the past year, as investors continue to weigh the company’s valuation against its ability to adapt.
Artificial intelligence is now the biggest question facing Dropbox and the broader software industry. Some investors fear AI models from companies like OpenAI and Anthropic could simplify work in ways that undermine existing products. Houston pushed back on that idea, arguing that new technologies often create exaggerated near-term expectations. He said he has not seen customers cancel Dropbox because of ChatGPT use, and he believes the company still serves a large and durable user base.
At the same time, Dropbox is leaning into AI with products such as Dash, a tool that helps users search and work across documents and messages from multiple apps, including content beyond text such as video and audio. Analysts say the feature could help position Dropbox for a new phase of growth, even as the company remains in a highly competitive category.
Houston said he plans to build something new in AI after leaving the CEO role. He described this period as one of the most exciting times to create products and said there was no single event that triggered the transition. Dropbox also announced that Mike Torres, currently a Google product executive, will join as chief product officer in July. Houston said he trusts Alkarmi to lead the next phase of the company and believes Dropbox is in the right place.
