I'm curious how you compiled the data. Perusing the Seattle-based entries, there are some whose URLs don't resolve, e.g., Pure Blue Water Innovation Nexus (probably defunct: http://pureblue.org/) and IntuitiveX (just needs SSL: https://intuitive-x.com/). This one doesn't appear to have an incubator or accelerator: Navigator CRE (https://www.navigatorcre.com/). Maybe the source dataset has some older entries that have gone stale.
