A pre-seed founder does not need Kubernetes. They need something that deploys in minutes, costs almost nothing at zero traffic, and does not fall over at the first sign of users.
Our default is the edge: static frontend on a CDN, a small serverless backend, and model calls routed through a gateway that gives caching, retries, and spend visibility for free. It is the same stack Kensink itself runs on.
Pick a single model provider and call it directly. Frameworks feel productive on day one and become a liability by month three. A thin abstraction you own beats a heavy one you rent.
The point of a pre-seed stack is to disappear. You should be thinking about your customer, not your infrastructure. If the stack is asking for attention, it is the wrong stack.
