Lots of solo-entrepreneurs struggle with CRMs, because the existing solutions are geared for large corporations or specialty verticals (e.g. healthcare, banking). Formerly, singletons used solutions like Access and FileMaker, but these are obviously deprecated in 2019 for all the usual reasons, some of which are good.
OP has created a general-purpose CRM fit for solopreneurs. I'd throw down right away for this if I wasn't worried about what happens to my data if this offering disappears, which is the Usual Problem with SaaS and one not really addressed by this product (nor is it reasonable to expect it to be.)
