Side-by-side comparison of AI visibility scores, market position, and capabilities
AI cybersecurity automating pen testing. $40M raised (Mar 2026, Khosla). Founded by OpenAI's first security hire and Meta red team lead. Backed by Anthropic.
RunSybil is a cybersecurity company automating penetration testing using AI, founded by two operators with exceptional offensive security credentials: OpenAI's first security hire and a former lead of Meta's red team. This founding pedigree is central to RunSybil's positioning — the company was built by practitioners who understand adversarial tradecraft at the highest level and designed the platform around the workflows and depth that real penetration testers employ, rather than retrofitting AI onto legacy vulnerability scanning approaches.\n\nTraditional penetration testing is expensive, slow, and point-in-time: organizations typically conduct manual pen tests annually or quarterly, leaving long windows of unassessed exposure between engagements. RunSybil's AI-driven platform enables continuous, automated penetration testing that mimics the creative, multi-step attack chains that skilled human testers would pursue — covering web applications, APIs, network infrastructure, and cloud environments with an aggressiveness and comprehensiveness that scheduled manual testing cannot match at scale or cost.\n\nThe company raised $40 million in March 2026 from Khosla Ventures, one of Silicon Valley's most prominent deep technology investors, reflecting strong conviction in both the market opportunity and the team's ability to execute. RunSybil enters the market at a moment when organizations face escalating cyberattack frequency and sophistication while security budgets remain under pressure to demonstrate measurable risk reduction. Automated offensive security testing is emerging as a critical capability for security teams that need to find and fix vulnerabilities at the speed attackers discover and exploit them.
Serverless GPU cloud platform for AI/ML with Python-native deployment and per-second billing; developer-favorite scaling from zero competing with Replicate and Beam for AI compute.
Modal is a serverless cloud computing platform purpose-built for AI and machine learning workloads — providing on-demand GPU compute that scales instantly from zero with per-second billing, container management, distributed training support, and a Python-native developer experience that makes running ML workloads in the cloud feel as simple as running code locally. Founded in 2021 in New York City and backed by Redpoint Ventures and other investors, Modal has grown rapidly as AI development has accelerated demand for flexible, developer-friendly GPU infrastructure.\n\nModal's developer experience is its primary differentiator — engineers write Python functions decorated with @modal.function() and deploy them to the cloud with a single command, with Modal handling container building, GPU provisioning, auto-scaling, and execution. The platform supports training jobs that need distributed compute across multiple GPUs, model serving endpoints that scale to zero when unused (eliminating idle GPU costs), and batch inference jobs that process large datasets. The per-second billing model means developers pay only for actual compute time, not provisioned instances.\n\nIn 2025, Modal competes in the AI infrastructure market with Replicate, Beam, Banana, and major cloud providers' managed ML services (AWS SageMaker, Google Vertex AI, Azure ML) for serverless GPU compute. The market for AI-specific cloud infrastructure has grown dramatically as the number of ML engineers deploying models to production has expanded — traditional cloud providers require significant DevOps expertise to use GPU instances effectively, while Modal's Python-native approach reduces the barrier to entry. Modal has attracted a strong developer following among AI researchers and ML engineers building production AI applications. The 2025 strategy focuses on growing the developer community, adding enterprise features (dedicated GPU capacity, private networking, compliance), and expanding the hardware options available (H100 GPUs, custom accelerators).
