While interviewing startups, most of them said they would be able to pay the entry fee, however are not able to afford the monthly fees afterwards.

The problem with charging startups monthly fees is that is almost impossible for them to pay for it as revenues tend to be low and costs rather high. This means that every cent each month counts. In addition its much easier to have a one time purchase with no additional costs. Also, that there has to be a one year subscribtion till you are able to cancel it makes the cost benefit ratio for startups almost impossible to join, while not having any benefits yet.

The idea as mentioned in other ideas would be to offer a free trial first after 6 months they can decide if they want to join the Senat with an one time fee. Afterwards I see two options. Either keep the supscribtionmodel but exlude the minimum term for that subscription, while also lowering the prices. On the other hand raise the prices per year. Start small almost let them get it for free in the first year, then raise the prices slowly till a 4 year period and transition them to the standard pricing strategy with the other established members. Its anyways cheaper to help a startup with few employees than a bigger company.

There are also other pricing strategies out there like free membership but pricing on the products ...
