Slide builds a business continuity and disaster recovery (BCDR) platform for managed service providers, offering block-level backups, backup verification, instant virtualization, and a line of physical backup appliances ranging from 1TB to 150TB. Its pitch is a modern platform built from scratch, free of the legacy code constraints that weigh down older backup products in the MSP channel.
The company was co-founded by Austin McChord, who previously built Datto into a major data-backup and cybersecurity provider before selling it to Kaseya in a multibillion-dollar 2022 deal, alongside Michael Fass, Datto’s former general counsel and chief people officer, who serves as CEO. Based in Norwalk, Connecticut, Slide raised a $25 million Series A in June 2025 and a $70 million Series B led by General Catalyst in March 2026, bringing total funding to roughly $95 million, and has since opened a UK office and a German data center to serve European MSP partners.
Innovation Matrix Assessment
Built a modern BCDR stack from scratch and shipped a full hardware appliance lineup (Z1/R1/B1) within roughly two years of founding.
Backup and disaster recovery provide direct operational insurance against downtime and data loss for MSP-served customers.
Raised $95M across two rounds in under a year (Series A June 2025, Series B March 2026 led by General Catalyst) and expanded internationally within that window.
BCDR for MSPs is a mature, crowded category dominated by Datto/Kaseya, Veeam, and Acronis; Slide's edge is modern architecture and founder pedigree, not a new approach.
No independent third-party test results or named enterprise case studies were found beyond growth and expansion metrics.
Ransomware-resilient backup remains a durable, non-optional need for MSP-served SMBs for years ahead.
Why CISOs Should Care
Gives MSPs and the SMBs they serve a modern, from-scratch backup platform rather than one built on decades-old legacy code.
What Makes It Different
A backup architecture rebuilt from the ground up by the founder of the category's prior leader, instead of incremental updates to an established legacy platform.
The Matrix Verdict
62/100 — INCREMENTAL INNOVATOR
Slide is an Incremental Innovator: fast-growing and well-capitalized with credible founder pedigree, but operating in a mature category where its advantage is execution and modern architecture rather than a new paradigm.
