Slide Raises $70M in Series B Funding to Expand Security-First BCDR Platform

Backup only matters when everything else fails. And when that moment hits, there’s no tolerance for patched systems or half-integrated tools. Slide enters the BCDR market with $70M in Series B funding led by General Catalyst, with Base10, Outsiders Fund, futurepresent, Vine Ventures, Glynn Capital Management, Benchstrength, Top Down Ventures, and Connecticut Innovations all leaning into the bet.

Congrats to Co-Founder and CEO Michael Fass and Co-Founder and Chairman Austin McChord. If those names ring a bell in the MSP world, that is not an accident. Experience has a funny way of compounding, especially when you have lived through the chaos of building backup and disaster recovery systems that actually have to work when everything else is on fire. Slide is built for Managed Service Providers from the ground up. Not patched together. Not layered onto yesterday’s architecture. Clean room code, modern infrastructure, and a security first mindset that treats resilience like oxygen instead of a marketing line.

The company launched its BCDR platform in February 2025 and wasted no time turning heads. High performance architecture powered by NVMe infrastructure. Native encryption baked in by default. Open APIs that let MSPs automate and integrate instead of babysitting backups at 2 in the morning. In a world where downtime costs real money and ransomware never sleeps, that kind of engineering focus hits different.

This is also a leadership bench that knows the terrain. Carlson Choi stepping in as COO with a background spanning Datto, Cork, and global digital operations. Philipp Heckel leading engineering with the kind of technical depth that comes from building systems that engineers actually respect. Sergio Espinosa guiding product with experience inside the MSP ecosystem itself. When the people building the tools have already sat in the chair of the people using them, the conversation gets a lot smarter.

The capital accelerates the next phase. Expansion across North America and EMEA. A UK office. A dedicated data center in Germany. Continued investment in the platform and new backup products designed specifically for MSP workflows. The strategy is simple. Build the infrastructure. Expand the ecosystem. Give service providers tools that move as fast as the threats they face.

There is a lesson buried inside this round that founders should study closely. Venture firms do not just fund ideas. They fund pattern recognition. Slide raised $25M in a Series A led by Base10 in 2025. Less than a year later the story sharpened, the product landed, the market gap became obvious, and General Catalyst stepped in to lead a $70M Series B. Momentum like that rarely shows up by accident.
