I write a newsletter about startups and investing—for ai builders of all levels.

I record mini-tutorials, review tools I’m testing, share my insights from an exited founder turned investor.

Hey folks,

I’ve been stuck in building mode since last week - I’m trying to build a browser-based version of Claude Code but in a very particular way.

The more I build the more I change my mind, restart, build new thing instead.

This process is actually good imo. It reminds me of no-code days and what I used to say then:

A product you can build in hours/days vs weeks/months can be thrown away easily because you’re not overly invested.

Think about it. You spend a few hours working on what you think is a good idea, you start using it, realise its awful and move on to the next thing.

It cleans out your backlog of ‘what if’ products you thought may make you rich/famous/cool. It’s pretty humbling.

The biggest unlock of AI nowadays is how generative anyone can be, you can put stuff out everywhere, all the time. It clears the cobwebs, it puts products into the wild that fail or flourish.

The way to get more ideas is to be bored or working on a different idea.

You can just build stuff.

This is why I tinker so much. It gives me questions on tools, processes and markets - it gives me time to ask questions, get things wrong and go down rabbit holes I may never have entered.

It’s quick-sand for the curious. (ps. as a kid I always imagined I’d be swerving quick-sand, anyone else?!)

Why was I thinking about this? Sahil (CEO Gumroad) and Logan's (Product Lead Google AI Studio) chat on AI in software engineering²³⁹ reminded me.

You should read Yohei’s ⁵²²feedback on autonomous agents⁵²² if you’re building a company in the space.

Replit is now at $100M arr¹⁴⁶, and a 91-year-old²⁷¹ is vibecoding with Replit for his church. Amen to that brother. When building, I’m finding myself use Replit a lot for getting a project started and setup - helps avoid server issues, getting database integrations right and little annoying bugs. But then I move to Cursor or others for more control. I see people doing similar with Bolt/Lovable too.

And a topic I’m passionate about; how ai apps are building hype in hopes that ai will catch up²⁶⁸ and bail them out.

OpenAI has removed all the items regarding the acquisition of Jony Ive’s startup named io. Why?¹³⁰ Because Iyo, another company building smart earbuds, is accusing them of copying their product after looking at it for investment purposes. But OpenAI denies it¹⁶⁹.

Skej⁴⁶⁷ is a scheduling agent that lives up to the hype. Drop it in your emails (or Slack channels) and watch it book all your meetings. It handles rescheduling, event reminders, and once you start using it, you will never want to schedule yourself again. Free to try at skej.com⁴⁶⁷.*

Meta is now partnering with Oakley⁸⁵ (beyond just RayBan) for another line of smart glasses. Are Oakley’s cool again? (sent from my 12-yr old self)

  A lot of scepticism around “prompt engineering” was caused by calling hand-wavy tricks from non-technical folks “engineering”. Context Engineering, on the other hand, is emerging in the context of building testable systems and products to make LLMs useful, aimed at technical folks. As time has passed, “legit” prompt engineering jobs have started looking more like that already, but “context engineering” as a term is a nice Pokémon evolution. - Keshav³⁸
