Linear

The Origin Story

Three Finns Walk Into Silicon Valley…

It's 2018. Karri Saarinen is leading design systems at Airbnb — one of the most respected design organisations in tech. His team is building beautiful things. Their project management tool? Not beautiful. He builds a Chrome extension to make Jira more tolerable. It takes Airbnb's product team by storm. The lesson was obvious: people were starving for something better.

"All big project management solutions were built for management. As a manager, these solutions work pretty decently. However, many software engineers and ICs disliked all of them."

Meanwhile, Jori Lallo was shipping code at Coinbase, and Tuomas Artman was building infrastructure at Uber. All three shared the same frustration. All three were Finnish. (Coincidence? The Finns have a word — sisu — meaning grit, resilience, stubborn determination. Perhaps that's not coincidence at all.)

In 2019, they quit their cushy jobs, moved fast, and built a product that felt like it was designed by people who actually wrote code. They didn't announce it loudly. They launched a private beta, got beta users from future unicorns like Cohere, Runway, and Ramp — companies that recognised quality when they saw it — and let the product do the talking.

Stephanie Zhan at Sequoia Capital heard about Linear through her Twitter network. "People she trusts were hyped about it." A $4.2 million seed round followed. The rest, as they say, is roadmap.

Karri opens Jira for the fourth time that morning. He closes it. He opens a code editor instead. "What if," he thinks, "we just... didn't do this to ourselves?"

Two other Finnish engineers are having the exact same thought in separate buildings across San Francisco. The universe nudges them toward a Zoom call. Linear begins as an idea scrawled on a digital whiteboard that — ironically — doesn't have any issues logged against it yet.

Before Linear, Karri and Jori had already built Kippt — a Y Combinator startup acquired by Coinbase. They knew the playbook. Tuomas had spent years building at Uber's mobile platform team. The three of them were, to put it mildly, not amateurs. Their pedigree wasn't luck. It was strategy. "I consciously took jobs in Silicon Valley to prepare for my next startup," Tuomas said. Schooling, disguised as employment.

The Trio Behind the Magic

Meet the Architects

CO-FOUNDER & CEO

Karri Saarinen

The designer who hated Jira so much he built a Chrome extension to fix it — and then built an entire company. At Airbnb, Karri helped craft the Airbnb Cereal typeface and built one of Silicon Valley's most admired design systems. At Coinbase, he was Head of Design in the early days when the company was defining what crypto UX could look like. He co-founded Kippt (YC) before that, and Rails Girls. The man has range. Linear's obsessive attention to craft and aesthetics? That's Karri.

Airbnb Coinbase Y Combinator

CO-FOUNDER & CTO

Tuomas Artman

The engineer who spent five years building Uber's mobile platform architecture and left to fix project management. Tuomas brought deep infrastructure chops to Linear — the product's legendary performance and speed owes a great deal to his philosophy that fast software is respectful software. He's been a software engineer for over 20 years, moving between developer, founder, and engineering manager roles. His take on tools: they should never get in your way. Simple. Radical. Right.

CO-FOUNDER

Jori Lallo

The third musketeer. A senior engineer at Coinbase who, along with Karri, had already built and sold a startup. Jori and Karri had co-founded Kippt — a bookmarking and knowledge base service backed by Y Combinator and eventually acquired by Coinbase. When you've already navigated a startup from founding to acquisition, your second company starts with serious advantages. Including knowing, very clearly, what not to do.

What They Built

The System for Product Development

Linear isn't just an issue tracker. It's an opinionated, end-to-end system for building software — from customer discovery through planning to shipping. Keyboard-driven. Blazing fast. No unnecessary clicks. No fields that exist for the sake of having fields. It makes the right choices for you so you can make the choices that matter.

⚡

Issues & Cycles

Lightning-fast issue tracking with a built-in triage inbox, sprint planning through "Cycles," and keyboard shortcuts that make Jira users weep with joy. Every interaction is optimised to feel instant — because slow tools are disrespectful to human attention.

🗺️

Projects & Roadmaps

Structured long-term planning that consolidates specs, milestones, tasks, and documentation in one place. Teams see where things stand without attending three update meetings. The roadmap that actually reflects reality, not the optimistic one you built for the board.

🤖

Linear Agent

Launched in public beta in March 2026, Linear Agent is the company's boldest move yet. An AI built directly into Linear that understands your roadmap, issues, and codebase. Assign issues to it. Ask it to synthesise feedback. Let it draft specs. The CEO declared "issue tracking is dead" — and he means it in the best possible way.

🧠

Triage Intelligence

AI that watches how your team has historically assigned, labelled, and prioritised issues — then does it automatically. Tribal knowledge, made into an algorithm. Duplicate issues detected. Patterns surfaced. Overhead reduced. The assistant that actually assists.

🔗

Linear for Agents

AI coding agents — Cursor, Devin, Codegen, Claude Code — are first-class citizens in Linear workspaces. Assign issues to them directly. They take a first pass. You review. The future of software development isn't humans vs. AI. It's humans and AI, orchestrated by Linear.

📡

Code Intelligence

Coming to Business and Enterprise plans: Linear Agent that actually understands your codebase. Non-technical teammates can finally ask "how does this feature work?" and get a real answer — without pinging an engineer at 11pm. Arriving soon.

The Journey

From Waitlist to Unicorn

2019

The Beginning: Private Beta & Seed

Three Finnish engineers quit big tech jobs, build a fast, beautiful issue tracker, and launch a private beta. Sequoia leads a $4.2M seed round after a Sequoia partner hears buzz on Twitter. Early beta users include Cohere, Runway, and Ramp.

2020

Series A: $13M from Sequoia

Linear raises its Series A led by Sequoia Capital. The product ships rapidly. The team reaches its first profitable month — not because they were trying to, but because they hired so carefully that costs stayed low. A happy accident of deliberate craft.

2022–23

Series B: $35M — Going Upmarket

Accel leads the Series B. Linear begins expanding from startup darling to enterprise contender. The company notices larger teams adopting the product and starts building features to serve them — without abandoning the speed and elegance that made it famous.

2024

Forbes: "Next Billion-Dollar Startup"

Forbes names Linear to its Next Billion-Dollar Startups list. The Enterprise Tech 30 lists them at #7 mid-stage. Scale migrates to Linear. The mobile app launches. The "Pulse" organisational feed ships. Linear is no longer a well-kept secret.

2025

🦄 Unicorn: $82M Series C · $1.25B Valuation

Accel leads an $82M Series C at a $1.25B valuation. Linear becomes a unicorn — and notably, the first to emerge from Helsinki's Maria 01 startup community. CEO Karri Saarinen's announcement? "Not much changes after a raise. We go back to building." Of course he did.

2026

Linear Agent: The AI Era Begins

Linear ships a new interface refresh, launches Linear Agent in public beta (March 23), and announces Code Intelligence. Over 15,000 companies now use the platform. Coding agents are installed in 75% of Linear enterprise workspaces. The future is already running on Linear.

Inside The Machine

Culture, Craft & Conviction

Linear isn't just a product company. It's a philosophy with a login screen. Everything — how they hire, how they build, how they talk to customers — is shaped by a set of deeply held beliefs about what good looks like.

🐢→🐇

Hire Slow, Win Fast

Linear became profitable before they intended to — not because of clever financial planning, but because they hired so carefully that costs stayed lean. The team jokes they "accidentally profited" by being too picky. A $1.25B unicorn with 203 people is not an accident.

✂️

Constraints Reveal Truth

CEO Karri Saarinen believes saying no is a superpower. "Constraints often reveal what's really needed and bring out the right arguments." Linear doesn't add features because customers ask. It adds features because they're right. That's the discipline of taste.

⚡

Speed Is Respect

Linear's obsession with performance is a moral stance. Slow software says: your time doesn't matter. Linear's keyboard-first interface and real-time sync load in milliseconds. Attention is the most finite human resource — Linear treats it accordingly.

🏗️

Building Is a Craft

"I believe that building companies is a kind of craft," Karri wrote in the Series C announcement. This isn't marketing copy. Linear's entire design philosophy — the opinionated interfaces, the sparse feature set, the refusal to add noise — reflects craftspeople at work.

🌍

Remote-First, Finnish-Rooted

Linear was remote before remote was required and distributed before distributed was fashionable. The founders are Finnish. The company is global. That Nordic sensibility — direct, functional, beautiful without being showy — runs through every pixel of the product.

🎯

Opinionated by Design

Linear doesn't do infinitely customisable. It does the right thing well. "Be opinionated. Validate early. Let the product speak." This deliberately limits their market — and that's the point. Win your segment completely before trying to conquer the world. The world, it turns out, is watching.

The Future

The Agentic Turn

Linear Agent — Now in Public Beta

Launched March 23, 2026. Linear Agent is built directly into the product and understands your roadmap, your issues, and increasingly your codebase. It can synthesise feedback, draft specs, create issues from Slack conversations, and save recurring workflows as reusable Skills. Available in the app, in comments, in Slack, and in Microsoft Teams.

AI Coding Agent Integration

Coding agents are already installed in 75% of Linear enterprise workspaces. Cursor, Devin, Claude Code, Codex, Amp — they're all first-class team members inside Linear, assignable to issues just like humans. The volume of agent-completed work has increased five times in three months.

Code Intelligence (Coming Soon)

The next frontier: Linear Agent that understands your codebase. Non-technical teammates will be able to ask how a feature works, who owns a system, or what recently changed — and get a reliable answer without interrupting a single engineer.

"Issue tracking is dead. The next era of product development is built on context and agency."

— KARRI SAARINEN, CEO · MARCH 2026

Linear's approach to AI is not "add a chatbot and call it intelligent." It's building AI as purpose-built capability within actual workflows. Real contextual problems first. Ambient intelligence second. The CEO put it plainly: "We go back to building. AI is coming to Linear, but we are approaching it from the ground up, starting with real problems first."

Did You Know?

The Sticky Note Edition

$35K Total marketing spend to become one of the fastest-growing issue trackers in history. (Yes, really.)

They named the company "Linear" — knowing full well that "linear algebra" has been around since 4000 BC. Their brand guidelines say it should always be used as a single word. They believe they can outrank ancient mathematics in search. Reader, they're trying.

75% Of Linear enterprise workspaces now have coding agents installed. The agents are working. The engineers are reviewing. Nobody misses Jira.

The founders built Kippt — a Y Combinator startup — before Linear. It was acquired by Coinbase. So their "first startup" was already an exit. Their second startup is a unicorn. The third will probably eat Jupiter.

5× Growth in agent-completed work over the last 3 months. The robots are shipping features. Fast.

Linear became profitable before they planned to — because they hired so carefully their costs stayed lean. "We jokingly say that being so picky helped us get to profitability quickly." Accidental frugality. On purpose.

#1 First unicorn from Helsinki's Maria 01 startup community. Finland's sisu in software form.

Karri Saarinen helped design the Airbnb Cereal typeface — a custom font used across all Airbnb branding. Before Linear, he was literally crafting how the world's most-recognised travel brand looked. That's not a background. That's a superpower.

So What Can Linear Do For You?

The Case For Switching

If your engineering team opens Jira in the morning and immediately sighs — Linear is for you. If your sprint retrospective involves the phrase "we need a ticket for the ticket" — Linear is for you.

Linear is purpose-built for teams that want to move fast without being managed by their own tools. Issue tracking, sprint cycles, project roadmaps, customer feedback loops, and now AI agents — all in one product, all working the way fast teams actually work.

The companies using Linear aren't choosing it because it's fashionable. They're choosing it because — as one OpenAI engineer put it — "you just have to use it and you will feel it." That's not a pitch. That's what good software feels like.

⚡ Software teams that want to ship without bloat
📋 Product managers who need real-time visibility
🧠 Founders & CTOs building lean, async-first orgs
🤖 Teams integrating AI coding agents into workflows
🌍 Distributed, remote-first organisations
🔁 Companies ready to graduate from Jira's complexity

Linear is actively hiring product development enthusiasts who believe smaller, focused teams achieve superior results. If you're someone who cares about craft, speed, and building things that matter — they're looking for you.
