Why "culture fit" quietly became "culture add"
The phrase has been treated as interchangeable at a lot of companies for years. The two ideas actually pull in opposite directions.

"Culture fit" was, for a long time, the default second-stage filter in hiring: does this person feel like the people already here. It is easy to apply, feels intuitive, and quietly produces the same kind of team over and over.
What fit actually optimizes for
Similarity. A "fit" interview tends to reward candidates whose communication style, background, and instincts already resemble the interviewer's own, which is a comfortable signal to read but not obviously a useful one for building a team that can see around more corners than the current one can.
What "add" asks instead
Not "does this person feel familiar" but "what does this person bring that is not already here." That could be a different way of approaching a problem, a background the team lacks, or just a working style that balances out an existing blind spot. It is a harder question to answer in a short interview, which is part of why "fit" stayed the default for so long, it was simply easier.
Why this is not just a rebrand
Treating them as synonyms misses the actual shift: "fit" is a similarity test, "add" is a complementarity test, and a team optimized for the first one tends to get more homogeneous over time, not less, as each new hire reinforces the existing pattern. A team explicitly hiring for "add" has to actively resist that drift, which takes more deliberate effort than trusting a gut feeling in the room.
What it looks like in practice
A structured post-interview question that is not "did they fit" but "what would this specific person add that the team does not already have," answered in writing, before the group discussion, so the answer cannot default to whoever felt most familiar. It is a small process change, but it changes what gets rewarded.
