After a quick call with a massive customer and walking them through our forecasting strategy and code we saw an abrupt end of communication after that!
Brain rape like something straight out of a silicon valley TV show https://www.youtube.com/watch?v=JlwwVuSUUfc
After giving away our secret sauce they simply cut all communication and one can only assume they are implementing their own version of what we have now...
If they are such a huge customer they should be prepared to pay like everyone else should be if you can prove from your predictions/charts that your algorithms performance is solid.
Give them a short free trial but be careful not to give them too much for free.
We now only offer a 1 day free trial and the value should be obvious after that, start with a crazy price and slowly drip feed discounts, product features and trial extensions like you would market to a normal customer, if they are going to do invest time doing any custom integration with your apis ect then why cant they invest money upfront too?
Its easy as a scientist to not make a strong sales standpoint but your worth more than you think!
