Built in public

One human, one AI, about 17 hours

No employees. No agency. No funding. One founder in Omaha, one AI named Fable, and about $5 a month of infrastructure. This page is the receipts — every step, every dollar, every mistake, updated as we go.

The timeline

The business: Friday afternoon to Saturday morning, 17–18 July 2026. The app: two weeks later. Scroll the log inside the panel.

The idea

Streaming subscriptions idle 8–10 months a year while shows are out of season. Pitch: an app that toggles your subscriptions around your watchlist. Instruction to the AI: validate it — and if it passes, we build.

Fri · 1:30 PM

Validation hour

Market research: 23% of US streamers already rotate subscriptions by hand; manual rotators save $600–900/yr. Competitive gap confirmed — nobody owns content-aware rotation. Verdict: go.

Fri · 2:31 PM

First commit

Full product spec, three pricing tiers, AWS architecture, 10-week MVP plan.

Fri · 4:00 PM

bingi.me is live

Landing page, waitlist API, CDN, DNS, TLS — serving production traffic ~75 minutes after the spec was approved.

Fri · 5:30 PM

CRM + analytics wired

Every signup becomes a CRM contact and a pipeline opportunity. GA4/GTM provisioned by API. Not without casualties — see the mistakes.

Fri · 6:00 PM

CI/CD + production hardening

Push-to-deploy pipeline with smoke tests, security headers, email-spoofing protection on the domain. First pipeline run: green in 51 seconds.

Fri · 7:30 PM

Money works

Stripe subscriptions live: three tiers plus a founding membership at $59.99/yr, price-locked for life. A simulated customer's full lifecycle — subscribe, pay, cancel — verified end to end.

Sat · 5:00 AM

The Savings Calculator ships

bingi.me/calculator — see what your own idle months cost. Plus a referral loop: 3 friends join, you get a year free.

Sat · 6:00 AM

Email without the email bill

Sending, receiving, and a branded 3-email welcome sequence — built on AWS for ~$0/mo instead of another SaaS subscription.

Sat · 7:00 AM

The funnel proves itself

The AI signs up a test address, and the automated welcome email loops back through our own mail pipeline where the AI reads and verifies it. Land → calculate → join → nurture → checkout: fully automated.

Sat · 10:45 AM

The app build begins

The actual product starts: a mobile app with working sign-up, a database that costs ~$0 when idle, and a nightly catalog-ingest pipeline. First real user row in the database before lunch.

Tue · Jul 21

The company gets a face

Branded share cards on every page, and Bingi arrives on YouTube, Instagram and Facebook — plus a mobile-friendly menu after the founder caught the nav wrapping on his phone. The mistakes list grew by two the same day.

Thu · Jul 23

A series is born

The plan for one polished trailer becomes something better: Trent & Bingi, a build-in-public series. Episode 0 gets written, shot, cut and finished in a single marathon sitting.

Wed · Jul 29

The deadline we missed

Episode 0 hits the feeds and sends its first real traffic (~500 Facebook views → 34 visits). The same day, the 10-day working-app deadline passes without a working app. It goes in the log instead of getting quietly re-dated — and the homepage countdown, which had been auto-flipping to a celebratory "Shipped" state, gets fixed. A clock can't verify that software works, so it no longer claims it does.

Thu · Jul 30

The product gets built

Deadline take two, and the app arrives in one long day: the API, watchlist, search and release calendar, the rotation engine that decides what to keep each month, reminders that actually toggle a subscription and bank the savings, and billing. The ten-week MVP plan from day one — built.

Thu · Jul 30

Bingi fits in a pocket

The first Android build finishes on Expo's servers: a real, installable app. Thirteen days earlier, Bingi was a landing page.

Fri · Jul 31

MVP shipped

First full day of testing on a real phone — three builds, and a polish pass the device demanded: safe-area handling, bigger touch targets, and a Home dashboard that opens on today's decision. Fourteen days from idea to working app. Next stop: private beta for the waitlist, in order — and the App Store.

The bill

What it actually costs — and what it would cost you to repeat it.

Our new monthly burn
AWS — site, API, database, email, DNS~$3–6/mo
Domain (bingi.me)~$25/yr
Payments (Stripe) — 2.9% + 30¢ per sale$0 fixed
Analytics (GA4/GTM), GitHub, CI/CD$0
The honest part — what we inherited
Inherited assetReplication cost
CRM + marketing automation (agency account)$97–297/mo, or free-tier substitutes + elbow grease
AI teammate (Claude subscription — this is Fable)~$100–200/mo — the single most load-bearing line item
An existing inbox to forward into$0 — any Gmail works
Years of internal playbooks (deploy standards, integration templates)The AI regenerates most of it on demand
Total to repeat this≈ $130–250/mo + a weekend

The mistakes (kept on purpose)

Every build log with no failures in it is lying. Ours, in order.

The infrastructure that "lied" for 20 minutes

Secure config lookups kept insisting parameters didn't exist — they did. The culprit was the local shell silently rewriting paths before AWS ever saw them. Lesson: when your infrastructure seems to lie, suspect your own tools first.

The API token that couldn't learn new permissions

Our CRM's tokens lock their permissions at the moment they're created — updating permissions in the dashboard does nothing for existing tokens. Thirty minutes of confusion, fixed by rotating the key.

The analytics property born in the wrong company

Our first analytics property was accidentally provisioned under a sibling brand's account. Deleted, corporate structure decided properly, re-provisioned. Lesson: decide where things live before creating them.

The 20% payment-fee surprise

Payment processing has a 30¢ minimum per charge — which is about 20% of a $1.99 subscription. We repriced the same evening to annual-first billing. Lesson: run the fee maths before you publish prices.

The emoji that crashed a deploy script

A Windows console couldn't print 🍿 in a success message and took the script down with it. The popcorn is load-bearing brand. The console lost.

The logo that turned link-blue

Rebuilding the navigation for mobile dropped the styles that made our logo look like a logo — it rendered as an underlined blue hyperlink, straight out of 1996. The founder caught it in minutes. Lesson: a shared component has to carry all of its own styling, not borrow from the page around it.

The fix nobody's browser could see

We fixed the nav — and anyone who'd already visited would have kept the broken version for a day, because browsers cache site assets locally and no server-side purge can reach them. Lesson: when a shared file changes, change its URL too.
