3 curves define a scalable startup
engineering's job is to make it so
You want users and revenue to grow exponentially.
Bugs per day to grow linearly.
Support work to grow logarithmically.

💡it's actually easier for large companies to adopt agentic coding because they already have the operational maturity to absorb a bunch of people flinging code at the problem

You have to force senior+ engineers to talk to customers.
Senior+ engineers are good at finding problems and then they’ll want to fix them.
You want those problems to be stuff customers care about not frameworks and refactoring bullshit

First time I tried Graphite a few years ago I didn't get. Tried again and love it. Stacked PRs are great when you have the right tooling
because how fast you code review is how fast you do everything

In praise of the stacked pull request | Swizec Teller
How fast you do code review is how fast you do everything. Your PR queue is the leading indicator of team velocity. Stacked PRs can help.
