Pre seed, 1 single constraint | I will not promote

Hey guys, I'm under 20 building a startup for myself but I have one single constraint I don't know how to get past My single thing blocking me from building what I want is a Claude Max x20 account, $250 CAD per month currently, I have a Claude pro account and a Codex pro lite account (not enough usage, I need Fable 5) I also have a concept landing page on a real domain with a real wedge in the market I've done contract work for startups, and have concrete tech knowledge from years of being on the computer since I was a kid. The issue isn't IF I can build the ideas I have, It's about if I can afford the AI subscriptions. I truly have no blockers to achieving a working app. Ive also been in the startup space long enough to know what steps to take. For context, so far I've applied to about 15 startup credits from services (like aws, azure, etc), applied to about 5-6 "cool grants" (like $1000 bucks for people like me, some denied), along with having a personal connection to an incubator / accelerator owner. The response I'm getting is something like "you need more traction". Im based in Vancouver BC and truly, $1000 bucks is more than enough to get myself going All in all, Im a solo founder with no team, planning on building most of the app myself (I am skilled enough + time + energy) My timing was unfortunate, as most incubators closed applications 1-2 weeks ago. None open right now. Question for everyone is what did YOU do when you were at this stage? Did you self fund for necessities like API costs, Subscriptions, etc? How did you bootstrap and get the funding to later get more "traction" and go for VC's? What are the key things I can do right now? Been applying to grants, not yet angel investors (not incorporated) and I have to wait for incubator openings. Should I keep shooting for quick grant cash from others? Remember all i need is an AI subscription to build All support is helpful, Thank you
