But we started as a "boutique" company that implemented everything requested by our then small number of clients (mainly out of desperation, we were self-funded and we didn't have much leeway, we needed those clients). It was as flexible as it gets before the LLM times.
But after a while, you start noticing patterns, an understanding of what works and what doesn't in a given context. Our later customers rarely requested a feature that we didn't already have or we didn't have a better alternative of. It's not like we had a one-size-fits-all solution that we forced on everyone. We offered a few alternative ways of working that fit different contexts (hiring an airline pilot is a very different context than hiring a flight attendant). And in time, this know-how started to become our most important value proposition.
At some point we even started joking about leaving the software business and offering recruitment consulting services instead.
Malleable software enables infinite variations of tools when the correct number is in the single digits.
