We had some hot debates about our beta program. We were seriously considering limiting access to the program and discussed various ways of implementing it, but the final show of hands pointed towards making the program public. The driving force behind this decision was the argument that Wrike's power is in its collaborative abilities.
It's not a single-person to-do list. It was created to help people work together to get things done. We want our earliest users to be able to have the full-blown Wrike experience. Limiting registration would mean limiting people's social networks, thus restricting Wrike's entire effect.
So we took the risk, decided to skip wasting our time on building a restrictive system and to pool our efforts into preparing the release of a top-quality program. We also bought substantial supplies of coffee to get us through the sleepless nights.
