I’m pretty certain AI quadruples my output at least and facilitates fixing, improving and upgrading poor quality inherited software much better than in the past. Why pay for SaaS when you can build something “good enough” in a week or two? You also get exactly what you want rather than some £300k per year CRM that will double or treble in price and never quite be what you wanted.
this means if I sell it to your business for the price of < your salary - you will get fired and business will use my version.
Why? because my will always be better as 10 people work on it vs you alone.
Internal versions will never be better or cheaper than saas (unless you are doing some tiny and very specific automation).
They can be better than current solution - but only a matter of time when someone makes a saas equal and better to what you do internally.
Sure almost anything will be better and cheaper that hubspot.
But with AI smaller CRMs that are hyper focused on businesses like yours will start popping up and eating its market.
Anything bigger than a toy project will always be cheaper/better to buy.
