35 Startup Ideas To Start in 2025
Greg Isenberg posts a list of 35 startup ideas to start in 2025 🚀
Pretty much all of them are AI based, which hints at where the puck is heading these days.
3 from the list that I particularly like 👇
8. tool finding abandoned AI/saas side projects under $100k ARR. acquirers want cheap assets. charge for deal flow. Could also buy some of these yourself. Build media business around it.
10. marketplace for AI implementation specialists. startups need fast deployment. 20% placement fee.
16. agent converting YouTube tutorials into interactive courses. creators leaving money on table. charge per conversion or split revenue with them.
I had a quick look around and a tool like Monsha could be used for the latter 💪
Find popular educational YouTubers in a particular niche, see if you can partner with them to turn their most-watched videos or playlists into courses.

ChatGPT Business Idea With 2000+ Bookmarks
🤖 Sam Parr uses ChatGPT as an executive coach / thought partner…
- It's spent loads of time asking me questions about myself, my goals, my strengths, weaknesses, business financials.
- I've given it books to read and asked "how would this author approach this problem."
- Even things like "what should the focus be this week to hit my goals"?
😕 But there's a problem…
I just use the same prompt window in ChatGPT.
This is less than ideal because the context window prolly isn't long and its forgetting stuff.
Plus if this prompt thread goes away, hours of training it is now lost.
What's a good way to solve this?
Lots of bookmarks and comments on the tweet.
Seems a lot of people would be interested in a layer on top of ChatGPT that solves this 👍

SaaS Idea: AI Lesson Plan Generator
💡 One of Adams Taranda's recent weekly SaaS ideas…
AI Lesson Generator
>Idea: Users type in their study goals → use ChatGPT to generate a lesson plan
>Distribution: SEO. Nice keywords here
>Monetisation: SaaS or usage-based
He shows a screenshot of monthly keyword volume such as 👇
- lesson plan generator – 1900, KD3
- ai lesson plan generator – 1400, KD2
- lesson plan maker ai – 1100, KD6
You could go niche here and create a lesson plan generator for different subjects, with teachers as your target audience 🎯
We've already seen that school printables and worksheets sell pretty well on Etsy…
I expect an app that generates lesson plans would appeal to the same audience 👍
How To Sell AI To Local Businesses (And Make $9k Per Month)
Jason Wardrop breaks it down in this 13-minute video 👀…
The idea is to set up a system for local businesses to automatically text back missed calls.
Plumber example 👇
- Average client value = $500
- Missed calls per week = 20
- Average close rate = 35%
So those missed calls could be costing the plumber $3000+ per month, since customers tend to move on quickly and call someone else.
Jason shows how you can set up an auto-text back service for the plumber (or other local business), and charge them $300-500 per month 🤑
You'd be leveraging software called HighLevel, which starts at $97/month after a free trial.
HighLevel has an AI conversation bot built in, which you train on client websites so it can immediately text back answers to common questions.
Sounds like the kind of thing you could pitch to local businesses, only sign up for HighLevel once you have some takers 👍
Paid Newsletter Breaking Down Viral Short-Form Videos
A recent post on Reddit 👇
The author goes on to break down the format and shares an AI prompt you can use to create a similar script for any niche 🤖
Lots of hate in the comments for promoting this kind of content, but the post has 350+ upvotes, so clearly there's a silent majority that wants more tips like this.
How about creating a newsletter along those lines? 🤔
Analyze viral short-form videos, break them down, and share AI prompts to help people script something similar.
Could have a free and premium version of the newsletter 🤑
Similar to Jason Levin's Meme Mail which we covered back in August.
In September Jason tweeted that his newsletter "already has 100s of paying subscribers and is profitable."
Using AI To Summarize 100+ Page Websites
💬 Sam Parr tweets…
Question: how can I use AI to summarize 100+ page websites?
He gives the example of this forum post…
this small coat maker has 500 pages. Mostly reviews + the founder replying to questions.
How can I easily upload these 500+ pages to AI and ask it questions?
Will replied with a solution he built in 45 minutes: forumscraper.com 🔥
But he admits it doesn't work perfectly and it's not optimized for SEO or anything.
How about building a better, SEO-optimized version?
Keyword research required to figure out the best angle 👀
A version of this could also be used by big review sites to produce AI summaries, perhaps sell it as an embeddable tool.

Build An Entire Competitor Intelligence System for $200
💬 Greg Isenberg tweets…
you can build an entire competitor intelligence system with AI and automation for $200
monitor your competitors github commits for development speed
track job postings for strategy shifts
analyze app reviews for weak points
scan pricing pages for positioning changes
claude synthesizes everything into daily briefs
n8n automates the whole flow
notion dashboard makes it digestible
used to cost $10k/month for similar insights
now it runs on autopilot for $200
it’s a beautiful thing
Basically a bunch of ideas there for a B2B SaaS or a productized service 💡
For example…
analyze app reviews for weak points
Sign up for the service, input the URL of a competitor on the app store / Amazon / Etsy, get back an AI-generated summary of critical reviews 🤖
Btw, it's easier than ever to build SaaS apps nowadays.
Even an 11 year old with no experience can build a working app in a few hours 🤯
