Nebulock is a technology company.
Nebulock provides an autonomous threat hunting platform, leveraging agentic AI and contextual security analytics. The platform proactively identifies hidden threats by correlating data across endpoint, identity, cloud, network, and SaaS environments. It moves beyond traditional indicator-based detection, focusing on attacker behaviors and tactics to surface sophisticated threats and deploy refined detection rules.
Damien Lewke founded Nebulock, drawing on over a decade in cybersecurity, including product leadership at CrowdStrike and Arctic Wolf. Lewke observed the limits of reactive, fragmented security tools, recognizing their struggle against machine-speed adversaries. This insight drove his vision for a system enabling scalable, proactive threat hunting accessible to all organizations.
Nebulock serves security teams aiming to enhance their threat detection capabilities. The platform empowers analysts, democratizing advanced proactive security for enterprises. Its vision is to redefine the security paradigm, enabling continuous, context-aware threat identification to eliminate blind spots often missed by conventional measures.

Nebulock is an AI-native cybersecurity startup building an agentic threat hunting operating system that automates detection of sophisticated threats like insider risks, lateral movement, and credential misuse.[1][2][3] Founded in 2024 by cybersecurity veteran Damien Lewke, it serves mid-to-large enterprises—including VC-backed tech firms, IPO candidates, financial institutions, and retail organizations with 1,000–5,000+ employees—by integrating seamlessly with tools like CrowdStrike, Okta, Splunk, EDR, SIEM, and IAM systems via APIs.[1][2][3] The platform solves alert fatigue and detection gaps, where teams waste 75% of time on false positives and miss 27% of real threats, by using multi-threaded AI agents for real-time baselining, natural language queries, and continuous learning that cuts noise by 85% and boosts true positives.[1][3]
Out of stealth in summer 2025 with $8.5M seed funding led by Bain Capital Ventures (including a $6M round), Nebulock has 14 employees (50% local, hybrid workplace), a double-digit customer base in production, scaling ARR and deal sizes monthly, and is nearing SOC 2 completion with enterprise features inbound.[1][2]
Nebulock emerged from founder and CEO Damien Lewke's frontline cybersecurity career, spanning Northrop Grumman defense contracting, early integrations engineering at CrowdStrike (Series C to IPO), product leadership in AI, threat intel, and detection at Arctic Wolf Labs, and a Master's thesis from MIT's CSAIL.[1] Lewke identified a core mismatch: enterprise attack surfaces have exploded due to constant internet connectivity, but security workflows remain outdated, siloed, and unable to scale or learn from past detections.[1][2]
After leading AI detections at Arctic Wolf, Lewke launched Nebulock in 2024 to deliver "agentic threat hunting for everyone," built by elite hunters from top security teams.[1][3] Pivotal early traction came during stealth, with trials across health tech, finance, and VC-backed tech firms, yielding production customers and monthly growth before public emergence in July 2025.[1][2]
Nebulock rides the AI-driven cybersecurity wave, where 90% of businesses feel unprepared for AI-powered threats and hunters drown in alerts, fueling demand for autonomous tools that filter, detect, and respond at "Internet speed."[2] Timing aligns with ballooning attack surfaces from cloud/identity proliferation and rising insider/lateral threats, shifting power to defenders amid competitive automated response markets.[1][2]
It influences the ecosystem by enabling proactive, learning platforms over retrofitted silos, hardening detections for late-stage tech/finance, and accelerating enterprise AI adoption—backed by top VCs like Bain Capital Ventures.[1][2] This counters breach economics, where known gaps cause 60% of incidents, positioning Nebulock as a force multiplier for overwhelmed SOCs.[3]
Nebulock's trajectory points to rapid expansion: $8.5M will fuel engineering hires for broader threat coverage (endpoints, identity, cloud), plus sales/marketing (e.g., new Head of Marketing) to chase larger deals amid ARR momentum.[1][2] Trends like escalating AI threats, regulatory pressures (SOC 2+), and agentic AI maturation will propel it, potentially dominating autonomous hunting as integrations deepen and customers scale.
As the agentic OS for threat hunting, Nebulock redefines cybersecurity from reactive chaos to proactive dominance—watch for Series A and mainstream SOC adoption by 2027.
Nebulock has raised $6.0M across 1 funding round. Most recently, it raised $6.0M Seed in July 2025.
