It Begins

A breakfast, a problem, and an idea

Chapter 1

Breakfast with Christof Zogg

The Conversation

  • 1.5 hours of intense exchange
  • A hundred ideas, to-dos, contacts
  • At the end: What did we discuss?
  • Good ideas get lost

"Same problem at work: hours of meetings, tasks fall through the cracks."

Breakfast with Christof Zogg
Chapter 1

My Ingredients

Everything's there — except coding

What I Can Do

  • Built app with 500K+ downloads
  • Launched wooden card worldwide
  • Go-to-market, support, operations
  • Security & client-server fundamentals
  • 7 years of conversational interfaces

What I'm Missing

Coding
No Swift · No Kotlin · No Xcode
MiMind App
Chapter 1

November 2024 — First Steps

Prototype

First Attempt with Lovable

Just seeing what these AI coding tools can do

Breakthrough

Whisper Understands Swiss German!

The showstopper for 7 years — suddenly solved

Name

"Bedo's Alfred" → DinBrudi

Everyone needs their butler. First mock data, then Whisper API.

Chapter 1

Christmas Holidays 2024 — Copy-Paste

The Workflow

  • 14-hour days, two weeks straight
  • Generate code in chat → replace entire file
  • Build → error → debug info back → repeat
  • AI doesn't know the project — no file access

The GitHub Disaster

  • Started project from scratch 3-4 times
  • Files corrupted, Xcode broken
  • SSH keys, push/pull = foreign words
2 Weeks
→ Version 1 in App Store
Chapter 1

January 2025 — Release & Reality Check

1 CHF
"One Franc" in Store
~500
Downloads
  • 40K LinkedIn views, great reactions
  • One-man show: code, logo, store — all AI
  • Bru (international version) follows quickly

"I don't need to explain my idea to anyone. I can implement it immediately and get instant feedback."

The Turning Point

Claude Code Max & access to the file system

Chapter 2

Two Moments That Changed Everything

~1995

DOS → WIN

One command. A new world. The start of my computer fascination.

2025

Copy-Paste → Claude Code Max

A colleague with a recipe app shows me Claude Code. Same effect.

"Suddenly a completely new world opened up that was previously closed."

Windows 3.1 / DOS
Chapter 2

Claude Code Max — The Gamechanger

Copy-Paste (before)

  • AI only sees what I paste
  • No access to project structure
  • Every change: manually copy

Claude Code Max (after)

  • Access to local file system
  • Sees all files, understands context
  • Edits directly, can build itself

The Explosion — Hasenbart Garage

Idea While Jogging → Prototype Same Day

  • Simulate real cycling route on indoor trainer
  • ½ day: working prototype
  • Full of bugs — but core question answered
  • Is this technically feasible?

"Even the best developers can't physically type that fast. It's pure physics."

Chapter 3

bionic — Old World vs. New World

9+ Months: Platform Search

  • Cycling routes in 3D on Vision Pro
  • Google Maps 3D only on Android
  • Pitched agencies, apprentice overwhelmed

Built Prototypes Myself

  • Framework evaluation with Claude Code
  • Found SwissTopo: public elevation data
  • Developer takes over with refined foundation

Chapter 3

Mockup vs. Functional Prototype

UX Mockup Functional Prototype
Shows how it could look Shows if it works
You can draw anything You see the technical limitations
Abstract for stakeholders Tangible, experienceable, convincing
Needs developer for validation PM validates independently

"A functional prototype has a completely different depth. In a mockup you can draw anything — that's completely irrelevant."

Chapter 3

At Work: Prototype as PM Superpower

🧪

On-Device ML Self-Coded

Tested Apple ML framework — zero developer resources consumed

🎯

More Precise Requirements

Technical feasibility tested myself — different conversation with developers

⏳

Let Ideas Mature

Test prototype for 2-3 months before it goes into development

📊

Convince Management

Functional demos instead of slides — much more tangible, much better

THE THESIS

What This Means
For All of Us

Product Managers, Developers, Teams

T-Shaped Developer & the Communication Problem

What Remains

  • Technical understanding
  • Architecture & security
  • Code reviews

What Changes

  • Writing code 10× faster
  • Cross-platform = grunt work
  • PMs arrive with prototypes

What This Solves

  • 25 years main problem:
    Communication
  • Prototypes instead of "you understand this, I understand something else"

"The question isn't whether developers will be replaced. The question is whether they're ready to evolve their role."

Lessons Learned

🚀

MVP Validation Never Easier

Build app, push, collect feedback, iterate

⚡

Tools Evolve Incredibly Fast

2024: 2 weeks → 2026: 2 days for the same scope

🎯

Product-Market Fit Still Hard

DinBrudi: no PMF — but the learning was priceless

📐

Spec-Driven Development Coming

Write specification → generate code → automate support

"Every month counts that you start earlier. Product Managers: Learn these tools. Developers: Prepare for PMs with prototypes."

The Problem: Without a Single Source of Truth

Your team loses valuable time

🔄

Endless Alignment Loops

Everyone works with different information levels. Result: Meetings about meetings, just to get everyone on the same page.

🔁

Always Explaining the Same Things

New team members, stakeholders, other departments – the entire company has to be explained from scratch over and over. Wasted time.

🔗

Context Lost Between Teams

Engineering doesn't know why a design decision was made. Sales promises features Product knows nothing about. Every team in its own bubble.
