What are some common factors that impede founders from building/scaling startups from their ideas. For an established startup, perhaps their challenge might be scaling the organization and customers, but for early founders it could be choosing the best infra, stack for the task at hand.
As someone trying to start their first startup, I've found that getting people to trust you and your product is very challenging. Finding my first users is tough.
The most obvious is the user experience. I found pbs was outdated in terms of its UI and experience. We want to make the process more fun and more exciting.
Other than that, we want to also allow privacy for users. It would cost extra for users, but if they wanted, we want to serve as a midpoint for shipping. You want a book shipped to you, but don't want your address sent to a random person? We will receive the book, and then send it to you.
Finally, we hope to have a larger inventory available. I couldn't find books I actually wanted on pbs.
Past that, and this is way in the future, we plan to expand to anything that is worth trading. Videogames is next on my list, then after that, records. The list is slowly growing, but I think our potential for expansion and scaling is really high.
Not having an audience or backing from an accelerator. It is amusing to see people, even on HN, get excited over a backed startup making the equivalent of half a feature in our product.
It's amusement instead of bitterness because we're already, and have always been, profitable doing machine learning projects for large organizations in different sectors and industries and we just happen to be building our machine learning platform to solve real problems we have first hand experience with. I suppose I'd feel differently if this were our "startup idea" and our success depended on that traction/audience.
However, we're always interested in people who do machine learning for a living [not just blogging/YouTubing/Mediuming/Tweeting/Audiencing about it] using our platform[0]. They may be dealing with problems we haven't seen, working on interesting projects, and it's always a blast to talk with these people.
So I think what you could do is join an online accelerator like pioneer.app . Your project is very unique, would be great to offer something similar for Julia notebooks, which currently do not have an official support for that, but has a large community.
For example: you get a huge boost in rankings when you first launch an app in the App Store. Not enough to be #1 above a Calm, but certainly #1 for medium-difficulty keywords. Once this advantage goes away, you'll need a strong ASO strategy and money to spend on ads to boost keywords.
Some of these opportunities are tough to overcome after you missed them. Press is very similar: reporters will cover a newly launched product, but new features likely won't get a feature.
The tech stack is far down on your list of concerns before you have established that there is a real product and a market for it. Use whatever you already know/are best at.
P.S. I'm working on a website that will allow people to swap their books. https://www.swapiverse.com/
