Thesis
AI in production needs new infrastructure.
Every AI product that reaches customers depends on compute scheduling, deployment pipelines, monitoring, security and cost control. Most of that stack predates GPU clusters, model inference and autonomous agents. Seed-stage companies are building its replacement now.
Where we invest. Companies that solve problems for teams already running AI in production: pipelines that recover from their own failures, systems that investigate and resolve incidents, and controls that limit what agents can do.
Why us. Our general partner leads technical due diligence on this layer for US private equity and venture firms. We apply the same review before we invest, which lets us back deeply technical companies that generalist investors struggle to evaluate.
Check size. First checks of $100K to $250K in seed rounds. We work with founders in English and Spanish.
Deal flow. ScaleUp Summit Network, the CNCF and open source communities our general partner helps lead in Latin America, Cuemby's client and partner network, and incubators and accelerators we partner with across the Americas.
Focus
What we back
Four layers of the production AI stack, from agents down to the GPUs they run on.
Security and agent control
Permissions, policy, audit and governance for AI agents that act on production systems.
Reliability and operations
Observability, automated incident investigation and remediation, and operations software for AI data centers.
Platform engineering for AI
Kubernetes-native tooling and CI/CD for teams that build with AI coding assistants and ship AI features.
Compute and GPU efficiency
Orchestration, scheduling and compilers that raise GPU utilization and lower the cost of inference.
Founders
How we work with founders
We focus on the infrastructure decisions that are expensive to reverse after seed.
Diligence-grade feedback
You see what our technical review finds across architecture, engineering and security, including the risks we would raise.
Series A readiness
We help you close the technical gaps a Series A investor's review would surface, before that review begins.
Infrastructure depth
Cuemby's engineers run production cloud and Kubernetes systems and build AI platforms for clients. We bring that experience to your architecture, scaling and cloud-cost decisions.
