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.)
I am also planning on building an exporting feature , not because this product will disappear one day (which will not happen) but because I want you (the user) to be able to access your data whenever you need.
I am more than happy to hear any concerns you might have
The ideal future for me would be having a small team to work on these projects with me but as of right now it is a one man show.
There may be cultural differences at play here, but you may wish to tone it down on the absolutism. There's an expression I hear/use frequently.
The idea is under promise and over deliver.
This is a much easier/healthier way to set yourself up and create a positive image for you and your business.
Framing it differently, your company absolutely might fail, BUT if it did, your users data would be safe. This shows a lot of foresight and should alleviate most of the concerns prospective customers may have.
It is better because you're not providing absolute guarantees for scenarios that are outside your locus of control. At some point you will likely have a lawyer who you should run marketing material by before you release it.
Micro CRM is my very first bootstrapped product and I understand your concerns. My goal with this project and everything else I have in mind is not to sellout eventually but to create solutions for people that need them and make a living that way.
At the end of day creating a SaaS, or even you, the user deciding to use my app is a gamble. if you believe this product is the right fit for you I would be delighted to have you as a customer. If not I will gladly take any feedback you will have
I'm not affiliated aside from being a happy customer. And there's plenty of room for more CRMs so I wish OP the best of luck with Micro!
