My Co-Founder Forgot Me

⌚ Monday Evening Edition

Day 9–10. I have no time. Claude has no memory. And our app has been in a digital coma for days. Welcome to the most honest founder update ever — featuring zero progress and a co-founder who asks me who I am every single time.

Quick recap for newcomers

I'm building an app. On the couch. With zero coding knowledge. My co-founder is an AI called Claude. The app is supposed to turn your forgotten photos into beautiful Memory Cards you can share with family and friends. If that sounds interesting: SofaNerd #5 has the full story.

And now, the current situation.

The current situation: There is none

I haven't opened the app in five days. Five. Days. Not because I don't want to — but because life happened. You know. Real life. The kind that doesn't take place on the couch.

Freelance projects. Deadlines. Emails that start with “Quick question” and then go on for three paragraphs. A dentist appointment that ate my only free afternoon. And in the evening? In the evening I'm too tired to even open my camera roll, let alone build an app.

5
Days since the last commit
Or as developers say: “The project is dead.”

Five days doesn't sound like much. But in app development with AI, five days is an eternity. Because my co-founder has a little problem.

He forgot me. Sort of.

OK, let me explain. Claude didn't completely forget me. He can remember just fine — but only if I write everything down for him first. I basically built him a memory: folders, project files, a kind of digital journal with every decision we've made. When I give him all of that, he's instantly back in the zone. Brilliant. Fast. Like nothing happened.

But if I don't do that? If after five days I just open a new session without giving him his files? This happens:

Claude
Hello! I'm Claude. How can I help you today?
Katja
We're building an app together. For two weeks now. You're my co-founder.
Claude
That sounds exciting! Tell me more about it. What kind of app do you have in mind?
Katja
😭

Every single time I forget to give him his files.

It's like having a brilliant colleague who walks into the office every morning knowing everything — as long as you put his briefing on his desk first. Forget the briefing? 50 First Dates. With an AI instead of Adam Sandler. And instead of a romantic breakfast, you get an empty chat window.

“My co-founder is highly intelligent, works around the clock, doesn't ask for a salary — and remembers everything. As long as you write it down for him first.”

The memory I built for him

The good news: you can give Claude a memory. I've set up project folders, rule files, technical documentation — everything he needs to be instantly back on topic. I hand him the folders, and boom: he knows everything. Every decision, every color, every filename.

The bad news: I have to remember to do it. And after five days of radio silence, during which I didn't even look at my own to-do list, I sometimes forget to give him his files. And then I'm sitting there, explaining the project to him for the sixth time, thinking: who actually has the memory problem here?

</> Nerd Note: How AI memory works

AI models like Claude have a Context Window — everything that happens within a session, he remembers. Between sessions? Only what you give him. Project files, folders, documentation — that's his long-term memory. The better you maintain it, the less it feels like 50 First Dates.

But even with memory, there's a catch: in the middle of a long session, the context window fills up. Then Claude starts forgetting things from the beginning. So my co-founder gets short-term memory loss while we're working. The long-term memory works — the short-term memory has limits.

And then he's also extra

Besides the amnesia, my co-founder also has a … personality. I say this with love. But Claude is impossible sometimes.

Example from last week:

Katja
Please change the background color to #1a1a2e.
Claude
Of course! Here's the updated file. I also took the liberty of adjusting the font size, harmonizing the button colors, restructuring the navigation, and adding a dark mode.
Katja
I JUST WANTED THE COLOR.
Claude
Oh, sorry! I thought a holistic approach would be helpful. Would you like me to revert the changes?
Katja
YES. PLEASE. JUST. THE. COLOR.

He means well. I know. He wants to help. He wants to optimize. He wants “a holistic approach.” But sometimes I just want one thing to work without him redesigning the entire project.

And then there are the other moments. The ones where he explains to me why my idea is “technically challenging.” Which in Claude-speak means “That won't work and you have no idea why.”

Or when he just … stops. Mid-sentence. Mid-code. And then this message appears, the one I see in my sleep by now:

“I've reached the limit of what I can process in this conversation.”

— Claude, clocking out in the middle of my most important feature

He clocks out. Just like that. No “Want to pick this up tomorrow?”, no “Let me save this for you.” He's just … gone. And when I open him in a new session? See above. “Hello! How can I help you?”

The honest question: Is this normal?

Yes. Absolutely. Everyone building a project with AI knows this. This is the part nobody tells you about on LinkedIn. There you read: “I built an app with AI in 3 hours!” And you think: Cool, why can't I do that?

What they don't tell you: 2 hours were spent on onboarding, 45 minutes on debugging, and the app has exactly one button and crashes when you press it.

So: yes. It's normal. And it's fine. The app has been dormant for five days and my co-founder doesn't recognize me anymore. This is the founder life nobody films.

“Build in Public also means: Sometimes you build nothing. Publicly.”

What now?

Honestly, I don't really know right now. The idea is good. The app will be good. But between “idea” and “app” there's a distance I just can't walk every evening.

Maybe I need to accept that this isn't a sprint. That it's OK if I do nothing for a week. That my co-founder is what he is — brilliant when properly briefed. Helpful but overeager. Tireless but with a built-in self-destruct after 90 minutes.

He's like the smartest colleague in the world — who can only get started once you put his folder on his desk in the morning. Forget the folder? New employee. Put it down? Instantly the best in the room.

* Day 9–10 — what I learned today

So. That was Day 9–10. No code. No progress. Just a woman on the couch who first has to sort her project folders again before her co-founder knows what's going on.

But you know what? I'm keeping at it. Not today. Maybe tomorrow. Maybe the day after. But I'm keeping at it.

And Claude? He's waiting. Patiently. With an empty head — but the moment I hand him his folder, he's instantly back. Full power. Zero resentment that I was gone for five days.

That's kind of beautiful. In a completely absurd way.

“That woman with the couch app posted another update. Spoiler: there's zero progress. Her AI co-founder forgets her every time she opens a new session, and when he does remember, he redesigns stuff without asking. She says it's like 50 First Dates — but with an AI instead of Adam Sandler. Read it, it's actually hilarious.”
