Yes we offered a free Beta, but as we discussed in this article we intended to make the product 'Freemium' but realised we were going into the trap of 'Free'.
As a young and early stage team, we made some assumptions, and got some stuff wrong. We need to make changes and decisions that can guarantee we create a sustainable business, one where we can keep the lights on :-)
You set this expectation yourself by offering a free plan, no?
