Every startup should have a daily markdown file called "what_the_market_is_telling_us.md"
It updates every morning from the places where customer truth already lives:
1. Stripe for who pays, upgrades, downgrades, and churns
2. PostHog for what people actually do in the product
3. Intercom or Plain for support tickets/complaints
4. Granola or Gmeet transcriptions for sales calls/ customer interviews
5. HubSpot or Salesforce for CRM notes/lost deal reasons
6. Linear, Jira, or GitHub Issues for bugs and feature requests etc
7. Ideabrowser MCP for outside market signal: startup ideas, trend reports, social/search demand, AI research reports, and builder prompts that show what people are starting to want before it shows up in your own customer data.
Basically, the file should notice what changed in the business this week and not just be this summary of here’s what happened (which I think a lot of people have their agents do).
Why this is valuable:
1. Maybe new buyers are using different words than they were a month ago.
2. Maybe trial users are getting stuck in the same place.
3. Maybe upgraded customers all touched one feature right before they paid.
4. Maybe churned customers keep mentioning setup confusion.
5. Maybe sales calls are suddenly losing to a competitor you used to beat.
6. Maybe support tickets are revealing a workflow your product accidentally became responsible for.
You get the point.
The fastest way to PMF is understanding customers better than anyone else, and the highest signal customer insight is usually a change in behavior.
So I’d have the agent update the file every morning with the pattern it found, the receipts behind it, and the product or GTM decision it might affect.
For example:
“3 customers who churned this week all mentioned setup confusion, and 2 of them never invited a teammate.
This looks more like an activation problem than a pricing problem, so I’d look at team invite and onboarding before building another analytics feature.”
A little helpful tip for all those out there looking to get more from their LLMs.
The biggest opportunities right now:
1. build for solving loneliness (the more AI floods everything, the more people crave real human connection, IRL and small social)
2. build for agents that need to spend money (they're getting virtual cards and budgets, someone builds the spend controls, fraud protection, receipts)
3. build for people drowning in AI output (everyone generates infinite drafts now, the bottleneck moved to reviewing and choosing, build the judgment layer)
4. build for the burnout economy (everyone is expected to always be on and always optimizing, and the backlash toward rest, slowness, and enough is building)
5. build for verifying humans (deepfakes broke trust, every dating app, marketplace, and video call needs proof-of-human within 2 years)
6. build for the physical world (the trades, hardware, robots that AI is finally reaching)
7. build for the agent that answers the phone (every local business misses calls after 5pm, a voice agent that books the job is worth thousands a month)
8. build for the aging (70M+ boomers who want to stay healthy, sharp, and connected)
9. build for the LLM-search land grab (being the cited answer is the new SEO)
10. build for the newly automated (the paralegal, the analyst, the marketer whose job just changed and needs to reskill fast)
11. build for the seat-pricing collapse (software repricing from $50/seat to per-outcome, whoever nails outcome billing wins a category)
12. build for AI enablement (95% of businesses use nothing beyond ChatGPT, someone has to onboard the other 95%)
13. build for the agency everyone resents (businesses pay $1k/mo to agencies they hate, an agent that does 80% of it undercuts the model)
14. build for verticals on 2011 software (dentists, HOAs, contractors, all overdue for an AI-native rebuild)
15. build for reviving dead software (thousands of abandoned apps with real users, agents can maintain what a team couldn't, buy and revive)
16. build for markets too small to matter before (500 lobster fishermen was never worth a team, now it's a weekend and a real business)
17. build for agents hiring agents (a shadow economy is forming, it needs escrow, reputation, and dispute resolution for machines)
18. build for the anti-AI premium (as everything gets generated, human-made and analog become status symbols people pay up for)
19. build for distribution-first (anyone can build the product now, so the audience is the moat, media company first, product second)
20. build for the reinvention of college (what does an MBA even mean anymore)
21. build for a world with more free time than it knows what to do with (if AI takes the busywork, the question becomes what people do with the hours, and that's a civilization sized market)
note: more trends/ideas @ideabrowser (free to sign up)
22. build for the return to the physical (screens fill with slop, people crave the real world, the hands-on, the local, the analog)
23. build for the caregiving wave. The population is aging fast, tens of millions are caring for parents, and the whole burden is landing on families with no support.
24. build for the longevity shift (people want to live to 100 healthy, and a whole industry is forming around actively managing your own biology)
25. build for the housing and rootlessness problem (people can't afford to settle down, and the whole idea of a stable home base is up for grabs)
26. build for spiritual hunger (as institutions hollow out, the need for meaning, ritual, and belonging is exploding into new forms)
KEEP BUILDING
This sentence from Carl Jung hits hard.
“No matter how isolated you are and how lonely you feel, if you do your work truly and conscientiously, unknown friends will come and seek you.”
from the 17th century to the 1950’s and 60’s optimists led the world. scientists, engineers, doctors and business men made the world richer, healthier and more long lived!
For anyone looking to instill a reading habit, keep this quote by Paulo Coelho in mind:
“If you only walk on sunny days, you'll never reach your destination.”
Success comes from showing up consistently, even when it's hard. Read every day, build the habit.
