The 20 BIGGEST startup ideas I’d build if I had 20 lives
-
biggest subscriptions: kill agent. average person bleeds $219/month on charges they forgot about. connect bank, show usage, cancel in one click. you keep 20% of what you save them
-
biggest insurance: AI that fights denied claims for you. insurers reject 30-40% on first try on purpose hoping you give up. most people do
-
biggest death tech: digital afterlife manager. you have 200+ accounts. crypto, subscriptions, passwords. when you die, half of it just.. disappears. 48% of americans have zero plan for this
-
biggest negotiation: AI that handles price negotiations over email. car deals, medical bills, salary offers. most people leave 5k-50k/year on the table because they hate the back and forth
-
biggest fintech: AI tax strategist. not filing, strategy. what your $2k/hour CPA knows but packaged for $99/month
-
biggest debt: AI settlement negotiator. americans owe $1.1T in credit card debt. collection agencies buy your debt for pennies on the dollar and then charge you full price. AI that negotiates settlements at 30-50 cents on the dollar
-
biggest manufacturing: micro-factory OS. 3D printers went from $100k to $200 but the software stayed at $50k. thousands of people making real products from garages with spreadsheets
-
biggest fraud prevention: B2B payment verification. 76% of companies got hit last year. $133k average per incident. AI that checks every outgoing payment before it leaves
-
biggest construction: permit automation. you’re waiting 3-6 months for paperwork that AI can fill in minutes. 1.5M permits/year in the US
-
biggest government: AI benefits navigator. $140B in federal benefits go unclaimed every year. people qualify but can’t get through the paperwork. 47 pages to apply for programs that exist to help you
-
biggest local biz: AI reputation manager. one 1-star google review can kill a small business overnight. monitor everything, auto-respond, push positive results up. most owners have no idea what’s being said about them
-
biggest freelance: AI contract reviewer. 70M+ freelancers signing stuff they don’t fully read. flag risks in 30 seconds, charge $19/month
-
biggest field work: voice CRM. electricians and plumbers don’t sit at desks. they need a CRM they can talk to while driving between jobs. 60M+ workers, nothing good exists
-
biggest proptech: phone-based property inspector. point at a room, get a full report. the $5B inspection industry still literally uses clipboards
-
biggest divorce: separation logistics AI. 750k divorces per year in the US. asset splitting, custody scheduling, document filing. lawyers charge $15-30k for what’s mostly paperwork and coordination
-
biggest renovation: AI cost estimator. homeowners always get 3-5 completely different quotes from contractors. scan your rooms, know the real number before calling anyone
-
biggest compliance: EU e-invoicing tools. 10M+ SMBs are forced to go digital by 2027 and have no clue how. $22B market btw
-
biggest immigration: visa application automation. people spend $5-15k on immigration lawyers for paperwork that follows a process. millions of applications per year, all manually filled
-
biggest legal: AI dispute resolver. small claims under $10k take months in court and cost more in lawyer fees than the claim itself. online AI mediation that settles it in days for a flat fee
-
biggest healthcare: AI second opinion. 12M americans get misdiagnosed every year. 795,000 die or get permanently disabled from diagnostic errors. upload your labs, get a second analysis before making a life-changing decision
every one of these has a customer already paying for a worse version of it.
I compiled a detailed growth plan for each of these for myself
drop which number you’d build first and I’ll send it to you
(maybe will discuss the terms how we can work together)
Or even better DM me if you’re not lazy and interesting guy to talk :<)
when it comes to the legal aspects, you need to consult with the appropriate people
that’s already existent mechanics and many financial apps are already doing this
point of trust will be resolved with partnering with big media face and giving him percentage (but it’s not tough mission if you’re building good)
tried to put here my soul and explain general ideas I have in my vault
honestly easier than most people think
- go to google maps, pick any city, filter by 3-star restaurants or barbershops or dentists
- read their bad reviews. screenshot them
- DM the owner on instagram or walk in. show them the screenshot and say “I can make sure this never happens again without you lifting a finger. free for 2 weeks”
- nobody says no to free
the product sells itself once they see a bad review get auto-responded in 30 seconds and their rating go from 3.4 to 4.1 in a month
after the trial you charge $99-199/month. for a local business that’s nothing compared to losing customers over a 1-star review they didn’t even know existed
scaling it: partner with local business associations, chambers of commerce, or just one well-connected barber who tells 15 other barbers lol
you don’t need a media face for this, just 10 happy shop owners who tell their friends
that’s why I release them in public and hope that at least anybody will comment or DM for business plan ahaha
since I can’t handle 23 startups at the same time
difficulty even with 3 lol
actually easy
- I have a lot of frens from different areas and I know their problems
- Each week I pick one niche and check out what they’re in lack of
- When I find some manual process which could be automated or which is too disgusting for any company in this niche, I just sit and create the plan how I’d fix it
- summarize ready solutions + my ideas + workflows from others niches, and getting ready to market solution
If gonna build it, just connect with 10 people from this niche and offer them this product for a test (if they would be up to try it and it really fits their interest)
Getting from them a feedback and have a ready idea for completing and go to public
finally have to end lol
btw, if any of those ideas will catch your eye, interesting to discuss what we can do together
