Critical Start Raises $40 Million in Minority Investment to Fuel Growth of Its Zero-Trust Platform and Managed Detection and Response Services

CRITICALSTART, a leading provider of Managed Detection and Response services, today announced a sizeable minority investment from Sagemount, a growth equity firm. CRITICALSTART plans to use its first-ever outside investment to significantly expand its market presence for the company’s Managed Detection and Response (MDR) services as it expands nationally – including new field offices in Los Angeles and New York City – to serve enterprise customers and its network of channel partners.

CRITICALSTART’s MDR services are differentiated by its unique Zero-Trust Analytics Platform (ZTAP), which ingests and investigates all alerts until they can be safely filtered out, resulting in a 99% reduction in alerts that require attention. The Company also offers a MOBILESOC application so customers can interact with the Company’s SOC analysts from anywhere to investigate, escalate and remediate security issues without being tethered to their desk. Underscoring ZTAP’s unique intellectual property and operational leverage, CRITICALSTART has been named an MDR launch partner for high-profile security technologies including Microsoft’s Advanced Threat Protection, Chronicle’s Backstory and Palo Alto Networks’ Cortex XDR/Traps. In addition, CRITICALSTART’s ZTAP and MDR service support a variety of other security technologies, including Splunk, Cylance, Carbon Black, and others.

“As more security partners and end customers recognize the unique value our ZTAP and MDR services add to their technologies, we’ve seen our MDR opportunities quadruple and our deal size triple compared to a year ago. This funding gives us the resources to accelerate our expansion and capitalize on the market demand for MDR services,” said Rob Davis, CEO at CRITICALSTART. “As an employee-owned company, CRITICALSTART was looking for a capital partner that understood the market opportunity and valued our culture and focus. Sagemount proved to be the perfect fit.”

CRITICALSTART’s MDR business grew by more than 200% last year and is on pace to more than double revenue this year. The Company was recently named by the Dallas Business Journal to its Middle Market 50 list as one of the fastest-growing midsize companies and was also named by CRN to its 2019 MSP 500 and Security 100 lists. The Company was a CRN 2018 Triple Crown Winner and named by MSSP Alert to its 2018 Top 100 list.

“When it comes to growth investing, the best companies are looking for a great partner, not just an investment,” said Michael Kosty, Partner, Sagemount. “As a high-growth, profitable private company, CRITICALSTART was successfully attacking the market for MDR services on its own but sought to accelerate product development and partnership opportunities. The company plans to capitalize on the huge enterprise opportunity for MDR services, which aligns perfectly with our strategy of providing flexible capital and strategic assistance to market-leading companies with recurring revenue models in high-growth markets.”

DC Advisory served as the exclusive financial advisor to CRITICALSTART. Financial terms have not been disclosed.
