Why subscribe

Not to read more, but to think further.

The internet has never been short of content. But as more of it accumulates, answers arrive ever faster. Many questions are compressed into conclusions before they have had the chance to unfold. What is truly rare is the room to turn a question over and over, weighing it from different angles.

Why subscribe

What this isn't

HtPi will not exploit dopamine loops to keep you scrolling, nor rush to hand you a neat summary that AI could generate in seconds.

How the writing works

The writing here begins with concrete questions, bringing together finance, data, AI, design, and threads that may at first seem unrelated—turning each question over, examining it closely, and considering it from different angles—

What we hope you take away is not merely a handful of new perspectives, but a way to unpack, connect, and keep questioning the next time you encounter something with no standard answer.

What you get

Paid members can access the full archive and in-depth articles. Go further, and you can enter the Lab to join discussions, events, and conversations, while also receiving discounts on classes. These are the tangible benefits.

  • Full archive & every deep dive
  • The Lab — discussions & events
  • Up to 15% off classes, applied on sign-in

But perhaps what you are subscribing to is not simply more content, but a rare corner of your own — a space where you need not rush to conclusions, and ideas can be turned over a few more times.

Membership details

What each tier includes.

Full archive and deep dives

Stream, River and Ocean members can read the complete archive and every deep dive. Source members retain access to public writing and occasional notes.

The Lab

River and Ocean members can enter the community Lab for extended discussions, members' events and conversations. Some events may require separate registration.

Horris Office Hours

Ocean members can join two live group video sessions each month, submit questions in advance, and take part in real-time discussion. These are not one-to-one consultations.

Class discounts

Your subscription follows you into the classroom.

Every paid tier earns a standing discount on every class I run — and the top tier gets in first, before seats open to the public.
