Current AIs often do a bad job of that. Sure, they know a lot of it. But they also get a lot of it wrong, and can’t tell the difference between genuinely good advice, and advice that sounds good but is practically worthless or even harmful.
(Of course I’m biased since I work for a SaaS firm. But I’m talking about them in general, not just my current employer.)
integration is likely the most valuable part of the puzzle, but it's also prone to disruption
I think all that's left are like <50 apps each with their own very bespoke and "power user"-ready interface
Having worked in healthcare, this is the current state (per provider, not physical building).
Or you can just ask your LLM to install https://github.com/CollaboraOnline/online
Between open source, LLMs, and SaaS vendors getting greedy and privacy invasive, the total pain minimization calc might shift for some orgs.
"We have this awesome internal version of Docs that we're responsible for fixing, upgrading, and doing support for" is not the flex "AI can code anything!" aficionados think it is. Especially when you also have similar internal versions of Sheets, Jira, Slack, GitHub, Linux, Postgres, and 100 other tools.
Making your own Google Docs is stupid unless your company's core business is document management.
OTOH Replacing SAP with a bespoke system will make a lot of sense for many companies.
SAP is already the worst of both worlds. It'll have been highly customized for your flow so you've got all of the headaches of bespoke software and all of the headaches of SaaS. And unlike Google Docs, it'll be highly integral to your core business.
Are there any software products that you think will survive?
I would absolutely NEVER steal or rewrite that. So much finanical stuff is baked into the business logic that impacts finance, regulations, hr, etc.
No do not roll your own ERP core.
Roll everything else
From what I've personally seen in SaaS AI agent development – if you try to build an AI agent to give customers advice in a particular business domain, you need to do a huge amount of work validating the answer quality with actual domain experts, and adjusting the prompts / RAG documents / tool design / etc to make sure it is giving genuinely useful advice. It is really easy to build a system which generates output which sounds superficially good, but an actual domain expert will consider wrong or worthless.
Software is much easier to create. It used to take 100 people to create a competitor SaaS product. Now it might take 3 people.
Traditional SaaS companies that don't have a data moat is in trouble.
Physical companies will dominate more than SaaS companies in the future. By physical, I mean energy and chips companies.
