Enjoyed our conversation with Tihon.

10 years in. Still hardcore.

I didn’t expect recovering my account to require recovering my consciousness. This particular recovery question triggered an existential chain of thought.

Two years ago we were obsessed with CAC:LTV.

Then churn.

Today it’s gross and net revenue retention.

The metric kept changing because the business kept changing.

One lesson: don’t fall in love with a KPI. Find the bottleneck, optimize it, and be ready to move on as your company evolves.

[Maksim Markevich @evthisrel]

AI compressed creation.

It didn’t compress:

Consistency.
Energy.
Ownership.
Taste.
Accountability.
The willingness to do boring work.

Those are still the moat.

Never underestimate the power of pushing back on multiples.

PIU used to mean P = I × U
Now it means Profit Interest Units

Real engineering work is not linear.

On a real project, you don’t “follow the workflow.” You bounce between modes.
You compare two options. You zoom out to sanity-check the strategy. You question the framing. You keep placeholders because the data isn’t there yet. You chase the one parameter that actually moves cost. And only occasionally do you get a clean, straight line to “done.”

Most tools are great at one of these modes and awkward at the others.

I wrote a post on the workflow taxonomy we use internally when designing utility-scale solar PV layouts — less as UI flows, more as modes of reasoning engineers switch between as the project matures.

If you’ve ever felt like your process is “messy” because it’s not linear, this is for you.

Depth shows up in strange places.

Today it was an almost two-hour run – steady effort, no shortcuts – with Our Oriental Heritage playing the whole time.

Neither is efficient. Neither is optimized. Both demand the same thing: attention, endurance, and staying with discomfort without reaching for an exit.

You can’t skim a run.
You can’t summarize a 40-hour book.

You just keep going – step by step, chapter by chapter – and something slowly settles into place.

That’s the long arc.

My whole life is a battle between engineering trade-offs and dopamine loops, running under the banner of compounding gains.

Seems like my New Year tradition: - slowing down for a mini retrospective while sitting in the A&E queue.

AI amplifies noise as much as it amplifies intelligence. So filtering becomes strategy. Understanding leads to ideas; execution is what turns them into value.

I'm not saying that everyone who holds equity in a startup should work on weekends.
But I do notice that many people who do work on weekends are the ones who own equity.

[Maksim Markevich @evthisrel]

Having a prototype idea over the weekend.
Writing it down on Monday morning.
Asking Zed/GPT-5 to build it while you're making coffee and staring into the void.

What a ridiculous, amazing world we live in.

Engineers think in zero-sum games.
Managers think in positive-sum games.

[Maksim Markevich @evthisrel]

Much slower, but much smarter IMO
