Thrilled to be back in the Bay Area for the next 6 months!

“Let me know who I should meet”, as they say. :)

PS: Still no shiny office on Sand Hill Road, but the temporary P9 US HQ is slowly taking shape.

Don’t know if it’s just me, but I’ve always found adding links in emails cumbersome.

So I built a tiny Mac app that lets you do the following:

1: Select one or several words
2: Hit a shortcut
3a: If it's clear what the right URL is, the app adds it.
3b: If not, the app gives you a few options to choose from.

It doesn’t only handle easy cases like “Point Nine” → pointnine.com. See below – I select a description of a blog post, not even its title, and it finds the post URL and suggests it.

To make this work, the app is connected to our MCP server, which is connected to our CRM and knows our Substack archive. If it finds nothing there, Claude searches the web.

If you’d like to use it, you can get the code here: lnkd.in/ggwMNYF2

You can give it context by connecting your own MCP server or adding CSV files. For web search you need an API key from Anthropic, Exa or Brave.

Before I let you head off for the weekend:

Tuesday was the real Liberation Day. The beginning of the end of MAGA and the Trump era.

I love America, and I’ve always believed that this country would eventually come to its senses. The Trump years will go down as a historic mistake, not as a reflection of what America truly stands for.

To our American friends: Welcome back to the free world. We’ve missed you. Europe will welcome you with open arms. We don’t hold grudges.
