You can ship things. Picking what to ship is the hard part.
You're a builder. You probably have:
A pile of half-finished side projects nobody wanted
A Twitter feed full of "AI agents will change everything" with zero signal
A Notion full of vague ideas you're not sure anyone would pay for
Weekends spent building, but nobody to sell to
The gap isn't your coding speed. With Claude Code or Cursor you can build a SaaS in a weekend. The gap is knowing what to build that someone will actually pay for.
Here's how Pulse actually works
Every Friday, 1 deeply-validated opportunity lands in your inbox — who's already asking to pay for it, the build plan, and where to find your first 10 customers. Plus a 3-line radar of what's next.
Mined, not invented
I scan dozens of Reddit subs, every relevant Hacker News thread, and Indie Hackers posts every week. AI filters the noise. I pick the keepers manually.
Real quotes, real wallets
Every opportunity ships with a direct quote from someone saying "I'd pay $X for this." No "might be cool" — only real money signals.
Solo-builder sized
Each idea is scoped to ~10 days of solo build time. No "build the next Notion" nonsense. Stuff you ship before motivation dies.

SAMPLE FROM ISSUE #0
3. Automated Tech Debt Quantifier
Demand signal
"We have a massive codebase with years of accumulated tech debt. When I try to convince management to allocate time for cleanup, they ask for ROI. How do I translate complexity and debt into dollar figures they'll actually act on?"
- r/AskProgramming · May 2026
Engineers feel tech debt every day — slow builds, risky deploys, onboarding friction — but it's invisible to management. The AI coding boom is accelerating debt faster than teams can review it. Enterprise tools (SonarQube, CodeClimate) exist but nothing cheap and fast for small teams who just want a simple ROI dashboard they can put in front of a CTO.
BUILD PLAN
GitHub / GitLab OAuth integration — pull commit history, PR churn, and file-change frequency
Static analysis layer scores complexity (cyclomatic, coupling) per module using an LLM pass
Cost model maps debt score to engineer-hours × team hourly rate → dollar figure per sprint
One-page PDF / Slack report — ready to paste into a management deck

Honest answers
Who is this for?
Indie devs and solopreneurs who want to build something people will actually pay for, instead of guessing. If you've ever shipped a side project that flopped because nobody wanted it, you're the target.
What's in each Friday issue?
Every Friday issue is free and covers 1 validated opportunity + a 3-line radar. The paid Build Pack is the full dossier for that opportunity.
How do you source the opportunities?
Reddit (multiple active subs), Hacker News (Algolia API), Indie Hackers, and Twitter/X builder threads. AI filters noise, I pick the keepers manually. Every issue is hand-finished — no automated dump.
What's the refund policy?
7-day no-questions refund on any Build Pack. Email me and I'll process it.
Who runs Pulse?
Solo dev, anonymous handle for now. Follow along on X: @kromzdev

What's the format of each issue?
~12 min read. 1 validated opportunity per issue. Each one includes: the exact quote that proves demand, a 3-step build plan, pricing benchmarks, and one honest risk. PDF archive included for paid subs.
