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

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.

“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 Datadog SRE

A site reliability engineer or platform engineer at a company with a production system that people depend on. Datadog is their window into that system. They've built dashboards that tell the story of what's happening in production. They've written monitors that page them when something goes wrong. They've been paged at 2am by monitors they wrote themselves and have opinions about that experience. They are better at Datadog than most people at their company and still feel like they're using 30% of what it can do.

“Not a single dramatic moment — more like a Tuesday at 3pm when they realized they hadn't thought about alert fatigue from monitors that fire on normal variance — the cry-wolf problem in two weeks.”

The Datadog SRE

A site reliability engineer or DevOps engineer responsible for the uptime and performance of production systems. They chose Datadog because it combines metrics, traces, logs, and alerts in one place — but now they're paying for all of it and the bill is terrifying. They've built dashboards that are beautiful, alerts that are precise, and runbooks that nobody reads. They are the person who gets paged at 3 AM and needs to determine in 90 seconds whether this is a real incident or a flapping alert.

“The shift was quiet.”

The Fly.io Container Developer

A backend or full-stack developer who needs to run server-side applications — not just static sites and serverless functions — and wants them deployed globally without managing Kubernetes or paying for managed Kubernetes overhead. They found Fly.io and found a platform that takes a Dockerfile and runs it near users. They `fly deploy`. It works. They have opinions about Fly.io that include real affection and specific frustrations, which is the relationship one has with a platform they actually depend on.

“It happened mid-workflow — they're deploying a Phoenix application — Elixir, with WebSockets and a persistent database connecti.”

The Segment Data Architect

A data engineer or analytics engineer who manages Segment as the central event routing layer. Every product event — page views, clicks, purchases, signups — flows through their Segment workspace before reaching the data warehouse, analytics tools, and marketing platforms. They are the plumber of the data stack. Nobody thanks them when data flows correctly, but everyone notices when it doesn't. They think in events, properties, and destinations. They've learned that the hardest part of data infrastructure isn't moving data — it's keeping it clean.

“The shift was quiet.”

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.

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

The Resend Transactional Email Developer

A full-stack or backend developer who needs to send transactional emails — password resets, welcome emails, order confirmations, notifications — from their application. They chose Resend because the developer experience felt like it was designed for someone who writes code, not someone who uses a drag-and-drop email builder. They write their email templates in React. The API is simple enough that they memorized it. They are not thinking about email infrastructure. They are thinking about their product.

“The shift was quiet.”

The Sanity Developer-Content Team

A developer who chose Sanity for a project that needed a content infrastructure serious enough to model complex relationships and flexible enough to be customized for a non-developer content team. They built the schema. They configured the Studio. They wrote the GROQ queries. The content team uses what they built every day. The developer's relationship with Sanity is: maintenance, evolution, and occasional deep satisfaction when the content model they designed months ago handles a new requirement gracefully.

“Not a single dramatic moment — more like a Tuesday at 3pm when they realized they hadn't thought about schema changes that require migration scripts for existing content — the cost in two weeks.”

The Stripe Platform Builder

A technical founder or senior developer building a platform where money flows between multiple parties — a marketplace, a SaaS with payouts, or a platform that onboards sellers. They chose Stripe because the API is good, but they've discovered that Stripe Connect is a different animal entirely. They understand payment intents but still get confused by the relationship between accounts, charges, and transfers. They are building financial infrastructure and it keeps them up at night.

“The first time a seller on their platform got paid automatically — money flowed from buyer to platform to seller with the correct fee split, no manual step, no CSV export.”

The Vercel Frontend Developer

A frontend or full-stack developer with 2–8 years of experience who discovered Vercel and decided that deploy-on-push preview URLs should be table stakes for every project. They've tried to describe the Vercel experience to developers still using other deployment pipelines and can't fully convey it. They use Vercel for personal projects, client work, and have advocated for it at their company — sometimes successfully. Their bar for deployment infrastructure is now set by Vercel, which makes everything else feel like a step backward.

“Not a single dramatic moment — more like a Tuesday at 3pm when they realized they hadn't thought about build times that climb as the project grows — especially Next.”

The Dovetail UX Researcher

A UX researcher or research ops manager at a company with a growing research practice. They've conducted enough studies that the insights are now a problem: they exist in documents, recordings, sticky notes, and people's memories. Dovetail is where they're consolidating that. They tag, they theme, they surface insights in a way that teams can find without having to ask a researcher. They believe the research repository is the infrastructure of a research-driven company. They're building it while also running new studies. It is a lot.

“Not a single dramatic moment — more like a Tuesday at 3pm when they realized they hadn't thought about research that gets done, presented, and forgotten — the insight graveyard problem in two weeks.”

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.

“The shift was quiet.”

The Clerk Authentication Developer

A full-stack developer at a startup who chose Clerk because building authentication from scratch — login, signup, email verification, OAuth, MFA, session management — is 2 months of work that adds zero product differentiation. They integrate Clerk's pre-built components, customize the flows, and manage users through the dashboard. They appreciate that auth "just works" but they've also hit moments where Clerk's opinionated approach conflicts with their product's specific needs. They are a developer who decided that auth is infrastructure, not a feature worth building themselves.

“The developer is building a new SaaS product.”

The Drata Compliance Automation Lead

A security engineer, compliance lead, or CTO at a startup who needs SOC 2, ISO 27001, or HIPAA compliance to close enterprise deals. They chose Drata because the alternative was spreadsheets, manual evidence collection, and $50K in consultant fees. They've connected their cloud infrastructure, HR tools, and code repositories to Drata for automated evidence collection. They understand that compliance is a business requirement, not a security one — the real security work is separate. They are simultaneously grateful for automation and frustrated by how much manual work remains.

“A teammate asked how they managed automate evidence collection across cloud infrastructure, identity providers, and HR systems.”

The Kajabi Course Creator

A course creator, coach, consultant, or subject matter expert who chose Kajabi because they wanted one platform instead of five. They have a course, probably a coaching program, possibly a membership community, and they wanted all of it to live together with one checkout, one email system, one analytics dashboard. They pay more for this than they would if they stitched together cheaper tools. They've decided that simplicity and integration are worth the difference. The Kajabi community is genuinely part of their decision — knowing that tens of thousands of other creators are building on the same infrastructure.

“A teammate asked how they managed run a profitable online education business without managing multiple platforms.”

The Notion AI Content Strategist

A content strategist, knowledge manager, or team lead who uses Notion AI as part of their daily workflow inside Notion. They don't use it to write blog posts from scratch — they use it to summarize 45-minute meeting transcripts into action items, turn rough notes into structured documents, answer questions about information buried in the team's wiki, and draft from templates. They've found the sweet spot: AI handles the structure, they handle the thinking.

“The shift was quiet.”

The Logseq Academic Researcher

An academic researcher, PhD student, or independent scholar who uses Logseq as their research knowledge base. They take notes on papers, link concepts across disciplines, and use the graph view to see how ideas connect in ways linear note-taking never revealed. They chose Logseq because it's local-first (their research data stays on their machine), uses an outliner format that matches how they think, and builds a knowledge graph without forcing a predetermined structure. They are building a second brain for their research, and they expect it to outlast their current institution.

“The shift was quiet.”

The Cursor AI-Native Developer

A software developer with 2–10 years of experience who switched to Cursor after a trial period and didn't go back. They've restructured how they code around the assumption that AI is in the loop. They write less boilerplate. They spend more time reviewing and directing than typing. They're faster on unfamiliar codebases than they've ever been. They're also developing opinions about when AI help hurts — about the kinds of errors that look right until they don't.

“The shift was quiet.”

The Cursor AI-Native Developer

A developer who has made Cursor their primary IDE and restructured their workflow around AI-assisted coding. They don't use AI as autocomplete — they use it as a pair programmer, architect, and refactoring partner. They've learned which prompts work, which context windows matter, and when to trust the AI vs. when to verify manually. They are faster than they were in VS Code, but they've also developed new anxieties about code they didn't fully write.

“The shift was quiet.”

The Greenhouse In-House Recruiter

An in-house recruiter at a company of 100–1,000 people managing 5–15 open roles at any given time. Greenhouse is their operating system for hiring. They know it well. They also know all the ways their company uses it wrong — job stages that don't reflect reality, interviewers who don't submit scorecards, hiring managers who give verbal feedback in Slack instead of structured feedback in the system. They are the connective tissue of a hiring process held together by their own follow-up.

“The shift was quiet.”

The Linear Product Manager

A product manager at a 20–200 person startup who moved to Linear because Jira was too heavy and Notion boards weren't structured enough. They work at the initiative and project level while their engineers work at the issue level. They need to see the forest while the team sees the trees. They love Linear's speed and keyboard shortcuts but struggle to get the strategic views they need without building custom views for every stakeholder meeting.

“It happened mid-workflow — the CEO asks "are we on track for the Q2 launch?" The PM opens Linear, checks 4 projects across 2 teams, counts completed vs.”

The Slack-Drowning Knowledge Worker

A full-time knowledge worker — marketer, PM, ops, customer success — at a company large enough that Slack has become the ambient noise of their workday. They didn't design the channel structure they live in. They inherited it. They have 12 unread DMs, are mentioned in 3 channels they rarely check, and have muted so many channels that important things occasionally slip through the cracks. They're not bad at their job. They're bad at Slack because Slack has become its own job.

“It happened mid-workflow — it's 10am.”

The Arc Browser Power User

A developer, designer, or technical knowledge worker who switched to Arc and reorganized their browser-based work around Spaces and Folders instead of horizontal tab strips. They had 40 tabs open in Chrome on a normal day. They were managing them by scrolling and guilt. Arc replaced the tab strip with something structural. They have opinions about it that they've refined over 8 months of use. The opinion is: it's better. The caveat is: it requires learning a new mental model that takes 3 weeks to stop fighting.

“The shift was quiet.”

The Craft Docs Intentional Writer

A product manager, writer, consultant, or knowledge worker who uses Craft as their primary document and note environment because it is the only tool that takes both writing and structure seriously at the same time. They're on Apple devices — Mac and iPhone, usually iPad. They've tried Notion (too database-y), Bear (too simple), Obsidian (too much tinkering), and Apple Notes (not embarrassed about this, just limited). Craft is what they settled on. The fact that it looks good is not superficial to them — environment affects their thinking.

“It happened mid-workflow — they're preparing a strategy document for a quarterly review.”

The Dropbox Creative Team Manager

A creative director, design lead, or production manager who manages files for a creative team — designers, photographers, video editors, copywriters. They chose Dropbox because it handles large files (PSD, AI, video) better than Google Drive and because the desktop sync means creatives can work in their native apps without learning a new tool. They are the person who designs the folder structure, enforces naming conventions, and answers the question "where is the latest version of the logo?" at least three times a week.

“The shift was quiet.”

The Dovetail Research Operations Manager

A UX research lead or research operations manager at a product company who uses Dovetail to turn the chaos of qualitative research — interview transcripts, survey responses, usability test recordings — into a structured, searchable insights repository. They tag, code, and synthesize findings so that when a PM asks "what do we know about onboarding friction?" the answer is a link, not a 3-week research project. They are the librarian of user insights, and they've learned that research nobody can find is research that didn't happen.

“A teammate asked how they managed tag and code qualitative data (transcripts, notes, videos) with consistent taxonomy.”

The Excel Financial Modeler

A financial analyst, FP&A professional, or investment banker who builds financial models in Excel the way architects build buildings — with structure, precision, and the knowledge that if one formula is wrong, everything above it falls. They've been using Excel for 5–15 years. They think in cell references, not coordinates. They know keyboard shortcuts that most people don't know exist. They've built models that a CEO used to make a $50M decision, and they've spent weekends debugging a circular reference that shouldn't have been circular.

“The CFO asks for a scenario analysis by tomorrow morning: what happens to cash flow if revenue grows 10% slower than projected and two enterprise deals slip to next quarter.”

The Attio Revenue Operator

A revenue ops manager, head of sales, or technical founder at a startup of 10–100 people who evaluated the legacy CRMs and decided not to inherit their constraints. They chose Attio because it's data-model-first — they can define what a record means in their business rather than forcing their process into Salesforce's assumptions. They are building their CRM from scratch. This is a significant investment. They are aware of that and have decided it's worth it.

“A teammate asked how they managed build a CRM that reflects their actual sales process rather than a generic framework.”

The Shopify App Developer

A developer or small agency building Shopify apps — either custom apps for specific merchants or public apps for the Shopify App Store. They know Liquid well enough to customize themes and the Admin API well enough to build features merchants ask for. They spend equal time writing code and reading Shopify's changelog to see what broke or changed. They've been through at least one major API version migration and still have scars.

“Not a single dramatic moment — more like a Tuesday at 3pm when they realized they hadn't thought about aPI versioning deadlines that force migration work on their timeline, not the developer's in two weeks.”

The Squarespace Small Business Owner

A photographer, therapist, consultant, restaurant owner, or small retailer who built their own website on Squarespace because it was the best option they could manage independently. They are not a developer. They do not want to be. They want a website that looks professional, is easy to update, and doesn't require a support ticket to change the menu. They've succeeded at this mostly. There are two things on their site that have been wrong for three months because fixing them would require understanding something they don't want to learn.

“The shift was quiet.”

The Craft Personal Document Creator

A professional in the Apple ecosystem — Mac, iPad, iPhone — who uses Craft for everything from meeting notes to project proposals to personal journals. They chose Craft because it feels native to macOS and iOS in a way that Notion and Google Docs don't. They value beautiful typography, smooth block-based editing, and the ability to work offline on an airplane and sync when they land. They are a writer who cares about the writing environment, not just the output.
