One of my biggest gripes with coworking places in my area, is that the aren't many affordable places and the ones that up don't give much information online.
While I understand why there aren't yet that many affordable options yet, since coworking spaces became mainstream a few years ago, that they don't offer that much info on their sites is something I don't really find a good reason for.
The kind of professionals that are most likely to use coworking spaces are used to do research about them online, where they compare before narrowing their options and then visiting them to make their decision. As such, not being findable online is something that works against them. While making a visit is important, is one of the last steps of the process.
Even after singing in to the coworking place, being able to manage their use of the space is something that is more comfortably done on the online site. Having to call before hand, or going physically, is something that only adds complexity to a decision that sometime is done on a moments notice.
Yes, visits can be planned with weeks of anticipation. But, the plans of those who make use of coworking spaces are fluid enough that those date can change at a moments notice. So, a website or an app are vital to make those changes on the fly when needed. Also, they are a great tool to manage the time they have left to make use of coworking spaces, and make them a better fit for the needs of the people who used them.
For these people renting a dedicate office is not really a possibility. They can't afford the expense, they travel often, or their main office is at home and they just need a more formal space than a coffee shop to meet clients or have team meetings, a coworking space is the ideal place for them.
As such, I do believe that affordable coworking spaces is an underserved market.
