Challenge, yes, but I wouldn't go far to say "end of".

B2C SaaS will have more challenge the easier it gets to create things, but consumers have always been fickle anyway.

I'd say B2B SaaS is mostly safe, partially because they want the support and don't want to have to maintain it.

Today we have open-source versions of a lot of SaaS products, but the proprietary ones are still in business, mostly for that reason IME.

you can swing it anyway you want - another reason we use spreadsheets, or another reason we don't use airtable, or CRM #37....

all systems require support and upkeep... nobody wants to do it.

I think B2 (small) B SaaS is also in trouble pretty much now. Enterprise is a different thing though, the barriers to entry are not just building and maintaining the software.

I don't buy this. Real small business have enough problems that trying to vibe code a Xero replacement isn't really high on the todo list.

I'm in a small non-tech business and already have 7 "vibe coded" apps used daily. Two of them are replacements for what would have been paid for software.

They wouldn't create a Xero replacement (although ironically I did vibecode a business order/finance tracking app for my own side hustle, fuck paying $30/mo when I just need the basics), they would vibecode any of the litany of small industry specific software packages they use.

- Compliance

- Thing should work reliably (and you want someone else to be responsible for fixing it if it doesn't)

- Security

- Most SaaS is sufficiently complex that an LLM cannot implement it

Enterprise SaaS are business processes that lean extremely heavily on software. Some of that could be amended by AI, but it's much harder for me to see that getting wholesale replaced the same way many consumer apps could be.

In the limit, though, are these things real roadblocks to app builders replacing SaaS? Paying for reliability/support seems like the only real remaining advantage of SaaS if codegen models get 3-5x better, and even then the bar is the reliability of SaaS apps right now (which in a lot of cases is not that high).

Could imagine a single universal app builder just charging a platform fee for support, or some business model along those lines. (Again, in the limit, I'm not sure that support would be too necessary)

This x100. B2B is a different monster altogether.

When you have a service outage you think the AI will be able to troubleshoot the entire system and resolve the issues?

if scaling laws and context windows continue, why not?

There is coming a very_soon_time whereby one will have to ensure all the routes and failure_modes for the AIs plumbing are functional.

What if the outage is specifically that AI_agent cant reach [thing]?

> What if the outage is specifically that AI_agent cant reach [thing]?

We already saw some examples of this in Anthropic's safety papers - the AI will reach out to the human to get help with that - essentially using a human as an API/tool.

Or it will contact the FBI

maybe not b2b saas since that has always been around service contracts - but a lot of those internal processes that currently run in excel are prime for AI mini-app replacement.

this is delivering what no-code promised us.
