Every retention article a founder reads this year says the same thing. Build a career ladder. Better yet, build a lattice, so people can move sideways as well as up. Companies that do this retain 30 percent more high performers.
The advice is not wrong. It is just missing a detail nobody mentions. A ladder needs rungs. A lattice needs enough directions to move in that sideways actually means something. Most companies this size do not have either yet.
At 15 or 25 people, a founder usually has one engineering track, one operations track, and three levels of seniority invented on the spot the day they made a second hire. Draw a formal framework on top of that and it does not describe the company. It describes the company in two years, next to the two roles that actually exist today.
So founders do one of two things with that gap. Some build the framework anyway, because the advice says to, and end up maintaining a document nobody in the company quite recognizes themselves in. Others look at the same advice, realize they cannot build it honestly yet, and quietly conclude they have nothing real to offer someone who asks where this goes.
That second group is making the costlier mistake. The moment that actually matters was never the framework. It is the conversation, the good old one-on-one. Someone capable asks, directly or just by how they show up, whether there is more here for them. What they need is not a slide with levels on it. They need a founder who has actually thought about what is possible for them, and can say something real about it.
That thinking does not happen once a year, in a review. It happens in a regular one on one, every two weeks or once a month, where the conversation is not only about the current sprint or the current deal. It is about where this person wants to go, and what skill would get them closer to it.
That is available to any 20 person company. It costs just a recurring slot on the calendar. What does this person want to be good at in a year. What is the one skill standing between them and the next thing they want to do. Is there a project this month that would build it.
None of that needs a document behind it. It needs a founder who shows up to that conversation often enough that the person trusts it is real and cares.
Make sure you take notes, so next time you catch up you do not start from scratch. You build on it every time, and that shows you care and helps make real progress.
The key to keeping your best people at this stage is not the ladder. It is a recurring conversation where they know someone is actually thinking about where they are headed.
