Spoke is a well thought out tool that offers a really useful level of function -vs- complexity for knowledge and request management. It's a much easier tool to run and administer than competing helpdesk solutions, and has a killer Slack integration front-and-center.
The team all through the sales and spin-up process is top notch and extremely responsive.
It's a fairly young product, so they're still polishing a few rough edges on the backend. I've not hit anything that even comes close to work-stopping, and they're smart and responsive with breakfix and feature roadmapping.
Spoke fills a great niche in the 50-250 person space in that it allows companies to do more with less support/admin heads. At this size, you need to have a system to create and action on requests, but probably don't need the features, complexity or cost of something like Zendesk. Once you approach 250+ heads, you may need some additional workflow or ticket automations that Spoke doesn't offer.
The biggest draw to Spoke for me is that from a user experience perspective, 99% of the interactions with the tool can happen in Slack, which most folks are in all the time in any case.
The team at spoke is one of the best I've ever worked with at any SAAS provider in any space. They're fast, smart, engaging, and have a genuine drive to set clients up for success.
