Yes, first you have to accept that it doesn't take 7 months but rather years. It is really really really hard to build a business with real revenue (did I stress on the word really?). It is even harder to build it solo.Most of the solo success story you hear either had expertise in their fields OR built something to truly solve their own problem first and then expanded to others and it usually takes 18-24 months or higher to hit some sort of escape velocity. Most people think that magic will happen in 2-3 months and then give up after that and you have to go longer than that. The risk is high but that is what it takes.
Now with AI and vibe coding, more products will be built but the hard part remains: how to find customers, sustainably support them and keep growing. There is no shortcut to it.
My suggestion:
1. Pick a very niche problem that you have some familiarity or can relate to. You don't need to be an expert in it but you have to feel that you truly want to work on it to make a sustainably living.
2. Build an MVP in 30 days max. With AI, this shouldn't be an issue. If going beyond 30 days, you are doing too much coding.
3. You have to find where your potential customers are and you have to do it MANUALLY. no automation bs. no ads (you don't have money and unsure if you know your target audience yet). So right now, you are trying to figure out who your Ideal Customer Profile (ICP) may be. You don't know yet. This can take months or even a couple of years (the scary part). But you have to do this manually. Go on Linkedin or use services like builtwith etc to figure out who may be using a similar product or a potential competitor. Then you have to email/call them directly.
4. You must have a social media profile. Look at the successful solo ones. they talk about EVERYGTHING online, I mean EVERYTHING. That helps build a personal brand which helps as a solo business owner.
5. Content Marketing. Sorry you are the marketer for your company. You cannot hire someone else to do that for you. YOU have to write the blog posts, YOU have to post the social media posts, YOU have to make those videos. And you gotta do it all if you want any chance of succeeding in 2026.
6. You have to go hard and specific for at least 12-18 months. This is the hardest part. Most people want quick results and if they don't see anything in 3-4 months, they give up. The goal is to see if you got at least 1 customer in say first 3 months. If you did, keep going and get the 2nd then 3rd. Note that your first few customers MAY NOT be your ICP but they will teach you what you need to know to build a successful product.
7. One tip: Being completely solo is overrated. I am not talking about co-founders. I am not talking about being solo founder but with a small team. That gives you a lot more mileage than just being by yourself. Yes it is hard to build a small team especially early on with no money but don't overthink the solo stuff and find 2-3 google people to work with if you can. Not necessarily as founders but freelancers/employees who can work in a small setup.
Source: Even though I am not solo by myself, I am a solo bootstrapped founder with a very small team that built a reasonably successful B2B SAAS business doing single digit million ARR. Not impressive by an VC standard but has given me everything for 10+ years and I love it.
