My office has cut down SaaS costs by a couple of tens of grand a year, simply by making our own versions using LLMs.

It is not that we didn't have the expertise to do so to begin with, but it would simply have been too expensive and time consuming. That was solved once the models became good enough.

There's a lot of money in the SaaS world, where the products are both unglamorous and one-trick pony-ish. Making your product LLM-proof can be challenging today, unless you happen to own a lot of data or lots of compute, and those two are the drivers behind your product.

Do you mind sharing the SaaS you were able to replace? If you don’t want to share the name, category would be interesting as well.
