my entire content strategy is this
give you free startup ideas + growth playbooks that work
i won't hold back
and every time you build something from my tweets/pod I'm sippin' a martini & cheering you on
your success is my ultimate flex
now go ship something & make me proud
The MOST obvious (but REALLY good) STARTUP ideas right now:
1. Zestimate for company data (what your data is worth to an AI lab)
2. Google Analytics for agents (see which agents visit your site and what they want)
3. Y Combinator for 1 person companies (back solo founders running a team of agents)
4. Okta for agents (who each agent is and what it's allowed to touch)
5. Marie Kondo for your company's data (clean it up so agents can use it)
6. FICO for agents (a trust score before an agent can spend money)
7. Geico for agents (insurance for when an agent makes an expensive mistake)
8. Datadog for agents (see every step your agents took)
9. Twilio for agents (phone numbers and texting for agents)
10. Upwork for agents (hire an agent for a job instead of a freelancer)
11. ESPN for AI (every model launch covered like a big game).
12. Shutterstock for robot training videos (get paid to film yourself doing chores)
13. Credit Karma for what AI knows about you (see it, fix it, delete it)
14. Norton for AI scams (protect your parents from fake voices and emails)
15. PayPal Buyer Protection for agent purchases (fixes it when your agent buys the wrong thing)
16. Geek Squad for AI (set up personal agents for families and small businesses)
17. Dell for private AI (AI in a box for firms that won't use the cloud)
18. Carfax for used GPUs (a health report before you buy secondhand)
19. Airbnb for idle GPUs (rent out computing power you're not using)
20. Rotten Tomatoes for AI models (real reviews instead of benchmarks)
21. G2 for skills (find the best skills for your agent)
22. Dropbox for your AI memory (take what your agent knows about you to any agent)
23. Canva for physical products (design it with AI and get it made)
24. ADT for your personal agent (alerts when your agent does something it shouldn't)
25. Hertz for robots (rent one for a move, a deep clean or an event)
26. Harvard Business School for internet businesses (a real education in building online)
27. Workday for agents (onboard, manage and offboard your digital workers)
28. Getty Images for your face and voice (license your likeness to AI safely)
29. Meta Muse for older adults (and other high LTV niche)
30. Google Ads for agents (pay to be what the agent recommends)
31. Loom for agents (a walkthrough of everything your agent did)
32. Plaid for agents (approved access to banks, airlines and stores)
33. Jiffy Lube for vibe coded apps (quick fixes when your AI built app breaks)
34. Ancestry for datasets (where your training data came from)
35. The organic label for human-made content (proof a person made it)
36. Strava for builders (track what you ship every week)
37. Honey that haggles for you (your agent negotiates the price)
38. SEM Rush for personal agent platforms (like Muse etc)
39. Frequent flyer miles for agents (loyalty programs built for agents)

I keep thinking about the PHP/railway hack.
Once you get hacked or your data gets leaked, it’s such a bad feeling.
You can’t take it back. It feels like a stranger was walking around your house while you were asleep.
Some of the most valuable companies on earth will be security companies.
Yes, 99.9% of Duo apps look like trash now but what did you expect?
Most companies won’t redesign for a new device until it has millions of users, so the first year is always a little messy.
So, startup idea for you coming from someone who has sold tens of millions of dollars of agency services: a Duo app agency.
Think about who’s buying this thing! Someone paying $2000+ for a phone the week it comes out is about as valuable a customer as you’ll find on the App Store.
They pay for apps, they pay for subscriptions, and they leave reviews. Most companies want those people badly, and most don’t have a spare team to redesign their app for a brand new screen. Hence, why the Duo apps look mostly trash now.
How to start a duo app agency:
Pick the categories where the bigger screen matters, like recipes, reading, trading, design and music. Record a short video of their app looking cramped on the Duo next to an AI mockup of what it could look like. Charge $40k to $75k to ship the redesign in a few weeks, and a monthly retainer to keep it right as Apple updates things.
One of the most obvious startup ideas out there right now. I’d start this today.
Sometimes the best startup ideas are the most obvious!
i think i'll add more cybersecurity ideas to ideabrowser.com (curated startup ideas, trends etc)
I think we’ll see a lot more of this.
The attackers were going after the AI keys stored on Railway, because an API key is basically a credit card for compute now.
Every company running agents is sitting on a pile of these keys!
here’s the 10 minute fix. rotate every key tonight, set a hard monthly spend limit in each AI dashboard, give every agent its own key, and turn on usage alerts so you know the second something spikes.
someone should build the tool that finds every AI key a company has, rotates them every week and pings you when spend looks weird. charge $99 a month. every startup running agents needs it yesterday.
I think AI agents are going to go through 9 stages before every business accepts them.
Right now we’re at stage 1, where big companies like Amazon, Delta etc are blocking them.
Here are the next 8 stages and the startup ideas I’d build.
Delta, Chase and Amazon are blocking AI agents.
The war on agents has begun, and here’s how it probably plays out:
Stage 1: Companies block agents because agents skip the ads and upsells.
Stage 2: Agents learn to act like humans, and it becomes an arms race.
Stage 3: The market splits. Companies that make money on sales let agents in, companies that make money on data charge for access, and the giants build their own agents.
Stage 4: A trusted middle layer for agent identity and payments becomes the standard way in.
Stage 5: Companies that welcome agents start winning customers from the ones that block them.
Stage 6: The agent blockers come back and let agents in on their own terms.
Stage 7: Everyone starts competing for agents with better prices, faster checkout and SEO built for agents.
Stage 8: The ads come back, and companies pay to be your agent’s first recommendation.
Stage 9: The agent war ends, and selling to agents becomes as normal as having a website.

Does anyone else find it lame when founders pick fights with each other publicly?
Do it in the DMs or not at all (ideally)
Meta Muse will probably create 1000+ millionaires
This is the most slept on arbitrage I’ve seen in years and it’s not even close.
Here’s how i’d build a 1 person business powered by AI/Muse with with $0 and 0 social following

notice..
> Delta is blocking AI agents from booking flights
> JPMorgan Chase and Charles Schwab block agents from accessing accounts
> Yelp requires paid data licensing for agents
> Amazon has blocked Grok bot and other shopping agents.
the internet is starting to block AI agents that were supposed to do everything for us
I've never seen an exceptional product that was designed by committee.
Too many cooks in the kitchen make products that are complicated and diluted. Every compromise feels small in the meeting, and together they water down the whole thing!
Postiz hitting $275k MRR so FAST is a great example of what I'm seeing: tools that agents use for things like posting, email, payments, phone numbers and browsing are going vertical.
A few other businesses I keep seeing go vertical:
- Data brokering. Selling rare/useful AND expert knowledge to labs and to companies training their own agents.
- Hosting for agents. Renting always on computers so people can run their agents 24/7. A lot of people want an agent working for them and have no idea how to set one up.
- Compute reselling. Buying GPU capacity in bulk and renting it out to smaller teams who need it for a few hours.
- Vertical harnesses. Agents built for one industry and one workflow, like insurance claims or construction bids.
- Skills. People are selling packaged skills that make an agent good at a specific job.
- Done for you agent setup. Local businesses are paying someone to set up agents for them, the same way they used to pay someone to build their website.
When you zoom out, almost all of these do one of three things. They sell to agents, they feed agents, or they house agents!
Postiz is now at:
- $275k in MRR
- 1,433 active trials
- 8,052 customers
And I keep on finding new places to get customers that my competitors don't go to. It's crazy!
