Co-founder of Porter (https://porter.run) here - Porter brings that easy PaaS experience to a k8s cluster that's running in your own cloud account (and manages it for you so you don't have to). We specialize in serving the segment of users who don't want to manage devops fully in-house but are outgrowing their existing PaaS providers.
We are offering a credit program for early stage startups that you can apply for here. Happy to fast track your application! https://porter.run/for-seed-stage-startups
