What Think|Stack does
Think|Stack (legal entity Horsetail Technologies, LLC) is a managed IT services provider founded in 2011 in Baltimore, MD, specializing in cloud infrastructure and cybersecurity for credit unions and financial institutions. Its core platform, Think|Stack 360, integrates AWS cloud design and migration, a 24x7 Security Operations Center (SOC), Managed Detection and Response (SIEM 360) built on Securonix UEBA, Network Operations Center (NOC), and Microsoft 365 / Azure Active Directory management into a single co-managed engagement model. The proprietary Collide journey-mapping methodology is used during onboarding to capture normal user and member behavior, feeding behavioral baselines that reduce false positives in the SOC. Complementary offerings include cybersecurity advisory, tech assessments, strategic IT planning, and ransomware tabletop exercises.
The company generates revenue through recurring managed services subscriptions (MSSP contracts for cloud, security, and network operations) and project-based professional services for migrations, assessments, and advisory work. In 2021, Think|Stack became a Credit Union Service Organization (CUSO) following a $5 million strategic investment from four credit-union-aligned organizations (CUSG, Christian Financial Credit Union, Mutual Credit Union, and Liberty Savings Federal Credit Union), and added a further $2.06M round in May 2022. It expanded its security capability set and credit union footprint through the May 2022 acquisition of Emergifi. Go-to-market is enterprise field sales plus inside sales targeting credit union CEOs, COOs, and VPs of Information Security, supported by a contract buyout promotion (up to 4 months free services plus 10-15% onboarding discount) to displace incumbent MSPs.
