## Evil Martians method

We have shipped to the VS Code and JetBrains marketplaces, the Chrome and Safari stores, and the Figma community. The same goes for SDKs: we treat SDKs as the product surface, down to its performance under load.

We build our own too. [Harmonizer](https://www.figma.com/community/plugin/1483474069475958506/harmonizer) generates accessible color palettes with the [Figma API patterns](https://evilmartians.com/chronicles/how-to-make-next-level-figma-plugins-auth-routing-storage-and-more) we have documented.

## Social proof

### Certora

[Certora](https://evilmartians.com/clients/certora) is a Series B blockchain security startup. We built their [VS Code extension](https://evilmartians.com/chronicles/smartly-contracted-ui-design-and-frontend-for-certora) for smart contract verification in two months, from design sprint to marketplace listing.

### NATS

We optimized the Ruby SDK for [NATS](https://evilmartians.com/clients/nats), the open source messaging system, and made it 3x faster under high load.

This was a major enhancement to the client so I appreciate the practical solution that was implemented to boost the client's performance and scalability.

### Teleport

[Teleport](https://evilmartians.com/clients/teleport) needed approvals to happen where its ops teams already worked. We built and documented five plugins, for Slack, Jira, Mattermost, GitLab, and PagerDuty.

### More ecosystems we built

- **[Recraft](https://evilmartians.com/clients/recraft):** the AI image generation platform with $42M in funding. We built a custom Discord bot as an acquisition channel.
- **[Playbook](https://evilmartians.com/clients/playbook):** [Chrome extensions](https://evilmartians.com/chronicles/how-to-make-complex-chrome-plugins-a-zero-gravity-guide) for this Series A storage platform, [converted to Safari](https://evilmartians.com/chronicles/how-to-quickly-and-weightlessly-convert-chrome-extensions-to-safari), plus a Figma plugin.
- **IntelliJ IDEA:** [language support built from scratch](https://evilmartians.com/chronicles/the-scenic-route-lessons-building-intellij-idea-language-support), and the lessons written up for everyone else.
