The constraint in enterprise endpoint management is the ratio of managed devices to human remediation capacity, a gap that autonomous endpoint management (AEM) platforms are designed to close without a manual handoff at each patch cycle. Action1, a Houston-based AEM provider, reported that the market for those platforms is tightening at the enterprise tier: six-figure annual recurring revenue deals grew 275% in the first half of 2026. High-value accounts expanded 167% over the same period, while the company held a 98% customer retention rate.
The pressure behind AEM adoption
Corporate device fleets now routinely run into the tens of thousands of endpoints per organization, and the window between vulnerability disclosure and active exploitation has compressed steadily. Manual patching workflows cannot sustain coverage at that scale without increasing headcount in proportion, which most enterprise security budgets will not support. AEM platforms address that ceiling by automating the discovery-to-remediation loop, the specific unit of work that drives both IT efficiency and security posture at scale.
What the H1 deal metrics show
Six-figure ARR deals growing 275% in a single half-year period indicates enterprises are writing larger contracts, which in software sales typically reflects platform consolidation rather than incremental add-on purchasing. When high-value account counts also expand 167% in the same window, the two metrics together suggest Action1 is acquiring new enterprise customers while simultaneously growing spend within existing ones. The company attributed H1 performance in part to expanded enterprise integrations and what it described as strengthened platform security, both of which are standard gating criteria in enterprise procurement cycles.
Retention as the operating metric
The 98% retention rate is the number that gives the ARR growth its context. In subscription infrastructure software, high retention at expanding deal sizes means customers are staying while the average contract grows. Churn in enterprise security tooling typically surfaces around integration failures or coverage gaps discovered during an incident. A 98% rate sustained through a period when six-figure deal volume grew 275% signals those failure modes are not reaching the point of customer loss at scale. Action1 was also recently recognized by Inc., though the announcement did not detail the specific designation.
The 275% growth in six-figure ARR alongside a 98% retention rate is the combination that defines Action1's H1 trajectory.
