Kubernetes Startups funded by Y Combinator (YC) 2026

Kestrel is an AI-native cloud incident response platform that brings self-healing to cloud infrastructure. It monitors cloud and kubernetes infrastructure 24/7, finds root causes, and generates exact fixes - so incidents get resolved in seconds instead of hours.

Metoro is an AI SRE for teams running on Kubernetes. Run one command to get autonomous root causing and automatic fix PRs. Batteries included, telemetry is set up automatically. Go from nothing to production ready in < 5 minutes.

We make running services on Kubernetes as easy as Heroku, but on your cloud and with all the flexibility and power of Kubernetes. Companies use Skyhook so that they don't have to hire dedicated infrastructure engineers. Although 50-70% of organizations have already adopted Kubernetes, most developers agree that it is too complex and difficult to manage. It is intended to be extremely flexible in order to solve pretty much everyone’s needs, but it can take a ton of work and many auxiliary tools to get there. As companies grow, they spend a lot on DevOps or Platform Engineers that try to reduce the burden on developers by gluing together all the 3p tools via custom internal tools. We are building an “internal developer platform” out of the box, with best practices and golden paths for building and operating services on Kubernetes. We do the research on the latest and greatest tools in the extremely vibrant ecosystem, and automatically integrate for you the tools you want to use. We operate on our customers code and in your Cloud environment, so they never locked in and never restricted, as is common with classic PaaS offerings. If you prefer a fully hosted environment like Heroku, Fly or Vercel, we’ll host a cluster for you and offer you a one-click migration to your own cluster when you want.

Sunpia lets developers easily experience the cost and speed benefits of serverless infrastructure, without having to rewrite their code. Developers annotate their code and Sunpia automatically designs a microservice version of it they can deploy on their own cloud.

Massdriver helps engineering and operations teams build secure, production-ready internal developer platforms in minutes. With over 50+ infrastructure components engineering teams can build golden paths quickly on Kubernetes, serverless, or VMs. Get the flexibility product engineers need, with the auditing and security operations teams’ demand. We handle all the boring parts of cloud operations like IAM, secrets, continuous deployment, alerting, and monitoring so your team can focus on the product. Massdriver supports anti-lockin, by running in your cloud, and open-sourcing all of our infrastructure components.

Netmaker is an open source virtual networking platform based on WireGuard. With Netmaker, you can bridge, clouds, the edge, IoT devices, and Kubernetes clusters. Netmaker provides the fastest possible virtual networks, with an average speed 10x faster than standard alternatives. Think of Netmaker like your VPC for distributed systems.

Signadot is a Kubernetes-native platform that empowers AI coding agents to verify code at scale. Combining fast, scalable ephemeral environments with a validation framework built for complex distributed systems, Signadot ensures high-velocity code generation results in safely merged pull requests.

Speedscale helps engineers validate their code with real, sanitized traffic. We simulate realistic production conditions in Kubernetes so you no longer need to manually script or use large and complex environments. Catch performance defects before they reach production and reduce weeks-long test cycles down to a few days.

Release delivers staging environments as a service. With Release a staging environment is automatically generated with every Pull Request which removes the bottleneck most companies have when they only have a single staging environment.

KubeSail is the home hosting company. We make it easy to take back your privacy, fix the internet, and de-google all at once: host apps at home! Plug in a spare PC or buy our custom home-hosting hardware https://pibox.io, install apps like PhotoPrism, NocoDB, and Minecraft, and enjoy complete ownership of your data. We build everything you need to make hosting at home viable and fun. For companies, we make it easy to deploy software on-demand for your customers (either in the cloud, or by physically shipping them pre-configured hardware) to your users. Companies like ChatWoot use KubeSail Platform to deploy instances of their software dynamically, the moment a user pays.

At Okteto, we are working hard at creating the next-generation development experience for teams of all sizes. Have you ever seen how long it takes a developer to set up everything they need before working on a feature? We are fixing that. We want developers to focus on building value for their teams instead of wasting time setting up local environments or trying to debug "production only" issues.

Mezmo, formerly LogDNA, is an observability platform to manage and take action on your data. It ingests, processes, and routes log data to fuel enterprise-level application development and delivery, security, and compliance use cases. Mezmo was brought to life by three-time co-founders Chris Nguyen and Lee Liu and included in the Winter 2015 batch of Y Combinator. In 2018 the company partnered with tech giant, IBM, to become the sole logging provider for IBM Cloud. Mezmo is on a mission to empower people who build solutions that shape the world. We’re doing this by delivering a platform that enables enterprises to get more value from their observability data in real time, regardless of source, destination, use case, or scale. We’re not the only ones working on this problem but we have a few things the others don’t. We’re cloud-native and know how to make the most of modern technology like Kubernetes. We have scaled a solution from zero to petabyte scale in a short amount of time, while supporting thousands of active users across multiple environments. We are hungry for change and are surrounded by enterprises telling us they’re hungry, too. We have a kick-ass group of people who are thinking about the problem analytically and are excited to change the observability world for the better. Mezmo has helped some of the world’s most innovative companies transform how they manage their systems and applications. Still, we know that we can help them get more value from their observability data by providing more flexibility and control over how they use it. This will enable teams to spend less time switching between data silos so they can focus on shipping better, more resilient, and secure products. We have momentum on our side. Last year we saw triple digit revenue growth and added 800 new customers to our roster. Recent accolades include being named to YC’s Top Companies, CRN’s 10 Hottest DevOps Startups, and EMA’s Top 3 Observability Platforms.

Pyroscope is an open source continuous profiling platform. With just a few lines of code it will help you debug performance issues and find bottlenecks in your code.

Convox provides an unparalleled development and deployment platform for apps. Deploy in your own account on the cloud provider of your choice.
