The Liveblocks Real-Time Developer

A frontend developer who needs to add real-time collaboration to an existing app — live cursors, presence indicators, shared document editing, or collaborative whiteboards. They chose Liveblocks because building WebSocket infrastructure from scratch is a project in itself, and they need to ship the feature, not the infrastructure. They understand React, they understand state management, and Liveblocks extends those mental models to multiplayer. They are building the "Google Docs" experience for their product.

Aha

It happened mid-workflow — the developer is adding collaborative editing to a project management tool.”

The Liveblocks Collaboration Developer

A frontend or full-stack developer at a SaaS company whose product needs real-time collaboration — multiple users working in the same document, canvas, or interface simultaneously. They've looked at building it themselves. The WebSocket infrastructure, the conflict resolution, the presence system, the storage — it's 3–6 months of work that isn't their product. They chose Liveblocks to compress that into a week. They are now the person at their company who knows how Liveblocks works. This is a niche form of expertise they didn't expect to develop.

Aha

The shift was quiet.”

The Supabase Full-Stack Developer

A full-stack developer or indie hacker who uses Supabase as their backend and thinks of it as their database, their auth layer, their file storage, and their API layer at once. They came from Firebase and wanted Postgres. Or they came from setting up their own Postgres and wanted the tooling. Either way they arrived at Supabase and found a backend they could move on from thinking about. They write SQL fluently. They use Row Level Security. They are deeply comfortable in the Supabase dashboard. They have strong feelings about their Supabase tables.

Aha

The shift was quiet.”

The Supabase Indie Hacker

A solo developer or indie hacker building a SaaS product where Supabase is the entire backend. They chose Supabase because it gives them Postgres, auth, storage, and real-time out of the box — and they can ship their MVP in a weekend instead of a month. They write SQL directly, use Row Level Security because they have to, and treat the Supabase dashboard as their admin panel. They are building a business alone and Supabase is the co-founder that handles the backend.

Aha

The shift was quiet.”

The Sanity Content Architect

A developer or content architect who uses Sanity because they think about content as structured data, not pages. They design content models that serve web, mobile, email, and API consumers from a single source. They've built custom studios, created real-time collaborative editing environments, and used GROQ to query content in ways traditional CMS query languages can't express. They are the architect of the content layer, and they treat content modeling with the same rigor as database schema design.

Aha

Not a single dramatic moment — more like a Tuesday at 3pm when they realized they hadn't thought about customizing the Studio deeply requires significant React knowledge, raising the bar for non-senior developers in two weeks.”

The Pitch Startup Storyteller

A startup founder, head of product, or strategy lead who creates presentations that need to look beautiful and tell a compelling story — investor decks, product roadmaps, board updates, customer pitches. They chose Pitch because it produces better-looking slides with less effort than PowerPoint or Google Slides. They value design defaults that make everything look good automatically. They collaborate in real time with co-founders and design team members. They are visual communicators who believe that how a story is presented is as important as the story itself.

Aha

It happened mid-workflow — the founder is preparing for a Series A fundraising round.”

The Replit Coding Educator

A coding instructor, bootcamp teacher, or CS professor who uses Replit because it eliminates the "but it works on my machine" problem. Every student gets the same environment, in the browser, with no setup. They can see student code in real time, run it, and give feedback without cloning repos or debugging local environments. They've taught programming long enough to know that environment setup kills motivation faster than any algorithm does. They chose Replit to remove the barrier between "wanting to code" and "coding."

Aha

A teammate asked how they managed eliminate setup and environment issues so students can focus on learning to code, not configuring tools.”

The Fly.io Edge Deployer

A backend developer or DevOps engineer who deploys applications on Fly.io because they need their app running close to users globally — not just served from a CDN, but actually computing at the edge. They've outgrown Heroku's simplicity, don't want AWS's complexity, and find Vercel too opinionated for non-Next.js workloads. Fly.io hits the sweet spot: Docker containers deployed globally with a CLI that feels developer-first. They're comfortable with infrastructure but don't want it to be their full-time job.

Aha

Not a single dramatic moment — more like a Tuesday at 3pm when they realized they hadn't thought about stateful workloads at the edge (databases, volumes) have limitations that aren't always clear until production in two weeks.”

The Google Analytics Marketing Manager

A marketing manager or digital marketer at a company of 10–200 people who is responsible for understanding how the website is performing and why. They are not a data person. They've been through the GA4 migration and have not recovered emotionally. They know enough to navigate the interface but not enough to build custom reports without three tabs of documentation open. They check analytics several times a week and leave most sessions with more questions than answers.

Aha

The VP of Marketing wants to know if the new landing page is performing better than the old one.”
