Datto founder’s startup Slide raises $70M to reinvent backup and disaster recovery for MSPs

A year after quietly entering the market, Slide is making a statement. The startup, founded by Datto creator Austin McChord, has secured $70 million in Series B funding as it sets out to reshape backup and disaster recovery for managed service providers.

The round was led by General Catalyst, with participation from Base10, Outsiders Fund, futurepresent, Vine Ventures, Glynn Capital Management, Benchstrength, Top Down Ventures, and Connecticut Innovations. The fresh capital gives Slide room to scale its infrastructure, hire new talent, and push further into international markets.

For a company that launched just last year, the speed of its rise stands out. Slide entered a category long dominated by legacy vendors with systems built years ago. Its founders believed MSPs were ready for a different kind of platform—one built from scratch for modern environments rather than layered on aging architecture.

“This funding marks a major milestone in Slide’s journey,” said Michael Fass, co-founder and CEO of Slide. “In our first year, MSPs have spoken loudly and clearly: they want a modern, secure, high-performance BCDR platform from a partner who is singularly focused on their success. This funding ensures we remain independent, product-focused, and resilient—while continuing to invest in innovation and in the people who make it possible.”

With $70M Series B Funding, Slide Aims to Scale Backup Platform Built for MSPs

Slide’s story carries familiar DNA for many in the MSP ecosystem. The company was co-founded by Austin McChord, the entrepreneur who built Datto into one of the most recognized names in backup and disaster recovery for managed service providers. Datto became a dominant platform in the channel before being acquired by Kaseya in a multibillion-dollar deal in 2022.

That background shapes Slide’s approach. Instead of adapting older infrastructure, the team built the platform from the ground up with modern storage, default encryption, and a design aimed squarely at MSP workflows. The company says the strategy paid off quickly, with partners adopting the system at a pace that surprised even the founders.

“The first year of Slide has been about reminding the channel what innovation looks like. New entrants in BCDR are very rare. The results and investment show the channel is recognizing the hard work and MSP alignment of this team. This round gives Slide the resources to expand the scope of our products and the geographic reach of the company. I could not be more excited about what comes next.” said Austin McChord, co-founder and chairman of the board.

The funding arrives as Slide begins pushing outside North America. The company announced plans to open a UK office and launch a data center in Germany, giving partners across Europe access to local infrastructure that meets regional data requirements.

For MSPs across the UK, the expansion signals a new option in a space where choices have remained limited for years.

“We’ve been watching Slide’s momentum over the past year and were genuinely excited to see a modern BCDR platform finally arrive in the UK,” said Derrick Ross, director of Hampshire Business Computers Ltd. “For MSPs here, having access to Slide’s high-performance architecture, security-first design, and partner-centric approach, combined with local support and in-region data centres, is a game changer. It’s refreshing to see a vendor truly listening to the MSP community and delivering innovation without the legacy baggage and the long-term contracts. We’re thrilled to bring Slide to our clients and to grow alongside a company that is clearly committed to the channel for the long term.”

Slide positions itself as a clean break from older backup systems that grew more complicated over time. The platform runs on NVMe-based infrastructure, includes encryption by default, and connects with other MSP tools through an open API ecosystem. The company promotes direct-to-tech support and a contract model that avoids long commitments, a point that resonates strongly with many service providers.

Slide is headquartered in Norwalk, Connecticut, and now operates across North America and Europe. With $70 million in new funding and a familiar founder returning to the space, the company is setting its sights on a category that has seen little fresh competition in years.

For McChord and his team, the goal is clear: rebuild the core infrastructure MSPs rely on every day and prove there is still room for a new player in backup and disaster recovery.
