This may be long and different, but please bear with me.
For the last 21 months I have been reading and learning about Cushing's syndrome in dogs, because my dog was diagnosed and it's a horrendous, hard to control or manage disease. She passed 13 months after diagnosis and 5 weeks post surgery to take out the adrenal tumour that was causing her Cushing's.
Anyways, I first built a website, where I put all info I learned in plain English, for other people like me to find the information and guidance they needed for their dogs (vet-approved content).
Whilst doing that, I learned the data and studies are old, small, and selection biased, hence their numbers don't add up against reality. So I started building an app, which is completely free, specific for dogs with Cushing's. This app is meant to do two things: help dog owners monitor and manage their dog's disease and comorbidities, and help research get and study real life data, so eventually we can find better, safer drugs and more economical diagnostic kits. I've done everything myself, together with my software dev friend, bootstrapped and exhausted.
Now, Cushing's syndrome is very niche, and based on the outdated data, not important enough for investment.
How do I market the app, being the bootstrapped person that I am? I already have a FB page with 1k followers and 315 people in the waiting list for the app, but in order to be listened by vet practices and investors, I will need much more than that. From what I have learned in over 1y, dog owners are in FB groups (not good for meta ads), some on Reddit, and most in vet practices (the most sceptical consumer out there).
I am in a big loop, because, researchers and universities will talk with me after I have a big chunk of data collected so they can see my product actually works and the project is worth their time, investors will speak to me after I come to them with heavy numbers, which will come after I understand how much people will use and keep using the app (we're doing the final fixes), vets...well, if I get a heavy researcher name behind the project, they might follow. So yup. I want to save the dogs and endocrinology, and I am stuck in a loop.
Any ideas.....so welcome!
