There aren't really any huge gotchas imho in 2025, just watch out that you don't get sidetracked delivering awesome developer infrastructure (preview environments! blue/green! pristine iac! its fun!) if there are actually more important things to be working on (there usually are). At early stage the product should usually be a monolith and there are a LOT of simple ways to deploy & manage 1 thing. Probably not an issue for you but costs will also tend to bump up quite a lot, you will be ingesting way more logs, tons more metrics etc just for the cluster itself, you may find yourself paying for more things to help manage & maintain your cluster(s) . Security add-ons can quickly get expensive.
