Who actually uses these products,
and what made them stay.

The Obsidian PKM Builder

A researcher, writer, software developer, or knowledge worker who has built their second brain in Obsidian and means it. They write in Markdown. They link notes intentionally. They have a vault structure they've iterated on at least twice. They use the graph view occasionally, for the pleasure of seeing their thinking made visible, not because it's the most useful view. They've installed 8–20 plugins. They have strong opinions about the right way to take notes, opinions that evolved over two years of using the wrong way.

“A teammate asked how they managed capture ideas in a format that connects them to related ideas automatically.”

The Obsidian Plugin Developer

A developer who uses Obsidian for their own notes and started building plugins to scratch their own itch. They now maintain 1–5 plugins with thousands of downloads and a Discord channel full of feature requests. They know the Obsidian API intimately but wish it was better documented. They build in TypeScript, ship through the community plugin store, and handle support in their spare time. They love the Obsidian community but sometimes feel buried by the expectations that come with a popular free plugin.

“Obsidian ships a new version and the developer's most popular plugin breaks.”

The Harvest Freelancer and Agency Owner

A freelancer, consultant, or small agency owner (2–15 people) for whom time is the product. They track hours against client projects and invoice from those hours. Harvest is where the financial reality of their business lives. They've learned that unbilled hours are lost revenue, that clients will dispute invoices without time entries to back them up, and that the difference between a profitable month and a break-even month is often the accuracy of their time tracking. They are disciplined about logging time — or they are trying to become disciplined about it.

“A teammate asked how they managed track time accurately enough that invoices are defensible and projects are profitable.”

The Rive Interactive Animation Designer

A designer or creative developer who builds animations that respond to state, not just ones that play and loop. They discovered Rive when they realized that Lottie was great for playing animations but couldn't handle the "and then when the user clicks, it does this" requirement. Rive's state machine changed their practice. They now build animations that are interactive first — hover states, press states, loading-to-success transitions, character rigs that respond to game input. They are comfortable in both the design and the runtime.

“It happened mid-workflow — they're building a loading animation for a fintech app.”
