I used to run Clara.io. It was a SaaS-based 3D editor. We shifted priorities back in 2015 but we were able to keep Clara.io running until December 2022 with less than one person investment per year. Details: http://www.cgchannel.com/2022/12/clara-io-is-closing-down/

Keeping a well designed website running isn't a major investment. Evolving a product though is.

I think the jury is out whether Twitter is going to continue to being a going concern. It could very well a major success.

But the fact that it didn't just crash and burn isn't that surprising.
