About MainStreet
One place for everything your team knows.
Every team we've worked with has the same problem: the knowledge that matters most is scattered across Slack threads, Google Docs, Notion pages, GitHub READMEs, and the heads of people who might leave tomorrow.
We started MainStreet to build that one place. Docs that are version-controlled like code. An editor that anyone can use. A home for everything your team has figured out.
MainStreet syncs with GitHub so engineers stay in their workflow. It has a rich editor so everyone else can contribute too. And it treats your docs as a living resource that gets more valuable every day.
What we believe
Knowledge compounds
Every doc your team writes makes the next decision easier. Decisions get better when you can see the ones that came before.
Tools should stay out of the way
The best tools feel like writing, not like configuring software. We build for the moment when the tool disappears and the thinking takes over.
Everyone contributes
Product managers, designers, founders — everyone who shapes what gets built should shape what gets written. In the same place, with the same ease.
Structure lets teams move fast
Branches and reviews aren't red tape. They're how teams ship without breaking what they've already built.
