What I learned launching my solo SaaS on PH last week

Hey PH.

Launched Briefance here last week. Solo founder, Istanbul, no team, no investors. Wanted to share what actually happened instead of the usual "thank you so much" post.

Quick context: Briefance turns chaotic client emails into structured briefs. Freelancer target. Paste the mess, get scope, timeline, budget, and follow up questions in ten seconds. Free tier has 3 briefs, no card needed.

Here's what the launch week taught me.

We built Briefance to kill the 1–2 hour client scoping ritual

Hey PH

Every freelance project starts in the same place. A client sends something like this:

"Hey, I want a website. Something modern. Maybe like Apple but for our industry. Also can it do that thing where the menu sticks to the top? My cousin said we need SEO too. When can you start?"

Then the ritual kicks in. You read it three times. Open a notes file. Try to figure out what they actually want. Make a list of what they forgot (scope, deadline, budget, domain, tech). Guess the effort. Guess the price. Write a polite reply asking for details. Wait two days. Get half an answer. Repeat.

We just launched Briefance — turning messy client emails into ready to send briefs

Hey everyone

After months of heads-down work, Briefance is officially live on Product Hunt today.

The problem we kept hitting as freelancers: every project starts with a messy thread a vague client email, a Slack dump, a half-finished PDF. You spend an hour just figuring out what they actually want before you can quote anything.

Briefance takes that mess and turns it into a structured brief: scope, budget, timeline, deliverables, and a sendable proposal. Drop in the email or PDF, get a clean brief back. Export it, share it, and track when the client opens it.

Briefance — Paste a messy client brief, get a structured proposal in seconds

"need a website, nothing fancy, $500, by Friday."

That was an actual client brief I received. I spent 2 hours just figuring out what they actually needed before I could start working.

After years of freelancing, I realized I was spending more time decoding chaotic client messages than doing the actual work. So I built Briefance.

The problem: Clients send a wall of text vague scope, no timeline, "flexible budget." You waste hours playing detective before any real work begins.

The security gap in AI generated mobile apps

Shipped 3 Android apps last month using Cursor. Realized none of them had basic protections against:

  • Debugging/reverse engineering

  • Root detection

  • Code injection

AI writes functional code, but it doesn't think like a security engineer.

Built a tool to bridge this gap upload .aab, get protection, no SDK integration needed. Would love feedback from fellow vibe coders.

When scanning is this easy (APK / AAB / Play URL), should mobile security start earlier?

Most teams delay security because scanning/building protection feels heavy.

But if you can secure your app just by:

  • Uploading an APK,

  • Uploading an AAB, or

  • Pasting your Google Play URL,

Would you use a security tool that works with APK, AAB and Play Store links?

Most security tools lock you into a single upload format.

But dev teams don t always have the same build ready sometimes it s an APK, sometimes an AAB, and sometimes the app is already live on Google Play.

That s why we updated AppShield to support:

Which security risks worry you the most in mobile apps?

While building KOBIL AppShield, we studied dozens of real-world attacks.

Some developers worry about reverse engineering, others about Frida/Magisk, and some about runtime manipulation.

From your perspective as a builder:

What’s the biggest mobile app security headache you’ve had?

We re getting ready to launch KOBIL AppShield, and we want to hear from you.

If you ve ever shipped a mobile app, you probably ran into at least one of these:

  • Integrating heavy SDKs

  • Reverse engineering attempts

  • Debugging/hooking tools bypassing your checks

  • Rooted devices causing chaos

  • Security reviews taking weeks

  • Team lacking mobile security expertise
