Hi there,
First off, thank you everyone for how kind you all seem here, and this work you’re doing! After reading through many of the topics this community really feels supportive. It’s rare I post in such places, but because of this, I feel more comfortable. So thanks. 
With that said, I have a question about non-commercially successful startups. In the description for proving OC1 it says, “You can demonstrate this by providing evidence of any genuine and significant product-led digital technology businesses you have established as a founder or senior executive which is currently active or has been dissolved in the last five years. Any company provided as evidence should demonstrate a level of income beyond solely covering the applicant’s salary and must have been commercially successful or otherwise demonstrate how the applicant meets the endorsement criteria.”
For the past two years I have been working on a startup I incorporated in the US about a year ago. We are building a product for early-stage startups and therefore been working on a pro-bono basis for design sprints. In fact we only have one contract for 4-figures, which isn’t even entirely related to the product but was really a small sum to participate in a specific research program we were running. Obviously, this does not demonstrate a level of income beyond my expenses. One of the reasons I’m moving to the UK is because my network in London is quite strong and I know I can build the product with commercial success there.
Do you think it would be sufficient for me to show the incorporation papers, a letter from me explaining the situation, and a recommendation letter (or 2 or 3 or 4…) from the companies who have participated in design sprints on a pro-bono basis?
