[Disclaimer: I'm founder of a competitor (<a href="https://circleci.com" rel="nofollow">https://circleci.com</a>, which offers CI/CD for iOS and Android as well as web apps, open source, etc).]<p>I don't know why it shut down, but my guess: customers didn't want to use one CI system for their iOS builds and another for their server-side builds. This was one factor in CircleCI acquiring distiller.io (which was a ship.io competitor) last year.<p>The history here is very interesting:<p>The original ship.io product was built by CISimple, and the assets were sold to Electric Cloud after CISimple shut down in 2013.<p>Electric Cloud is a ~13 year old VC-backed startup that sells a C/C++ build distribution service (think distcc, but much faster and better). (Interesting side-note: EC was founded by prolific HN contributor jgrahamc, and by John Ousterhout, who created TCL and coined the term "scripting language".)<p>EC's customers are mostly very big embedded systems makers, so it's a very enterprisy market. This market was good but AIUI their revenue growth flattened out sometime after hitting $10m/yr in revenue many years ago<p>A few years ago EC branched out into the Continuous Delivery space to rekindle that growth. Their continuous delivery products are AFAIK being sold in the same enterprisy top-down fashion as EC, as opposed to the bottom-up developery approach that CircleCI, GitHub, New Relic, Heroku, etc, use.<p>Ship.io was, I think, the first of EC's products to be sold bottom-up, and that was aimed directly at developers. I believe this is the best way to sell into this market, so it seems ship.io was going in the right direction. In fact, I believe it even operated somewhat autonomously from Electric Cloud, with a separate team based in SF instead of Silicon Valley.<p>I would guess they shut down because they didn't get product market fit (which would be true if their customers wanted server-side CI in the same product). But it's also possible (pure conjecture here) that the bottom-up autonomous feel of ship.io didn't gel with the top-down enterprisy culture of the mothership.
