Linear 代理生成工作量一年从 3% 涨到 50%，B2B 创始人该看什么

Linear published its tender offer news this week: $99 million of secondary at a $2.5 billion valuation, up from $1.25 billion at the Series C last year. Accel and 01A participated, with Salesforce Ventures and S32 coming in new. No primary capital raised. They’re cashflow positive with more cash in the bank than they’ve ever raised.

Buried in the middle of the post is the number every B2B founder should be looking at:

Agents are installed in 95% of paid Linear workspaces, and the share of work agents create went from 3% a year ago to 50% today.

Half the work items in one of the most widely used systems of record in software development are now being created by machines. That happened in twelve months.

3% to 50% in Twelve Months

I’ve watched a lot of adoption curves over 14 years at SaaStr and as an investor. Almost nothing moves like this inside an established workflow tool.

Normal enterprise feature adoption looks like 3% to 8% to 15% over three years, and you throw a party at 15%. Linear went from a rounding error to half of all created work in four quarters. This is also not a usage metric they control, like logins or seats. It’s the composition of the actual data going into the product.

Two caveats before anyone puts this on a slide. Linear says “the share of work they create,” not “50% of issues,” and we don’t know if that’s weighted by workspace or counted in aggregate across all of them. Installed in 95% of workspaces is an install number, not an engagement number. The 50% figure and the 7x figure are usage, and they point the same direction.

The cohort matters too. OpenAI, Cursor, Cognition, Harvey, Physical Intelligence, Legora and Baseten all run product development in Linear. The companies building agents are the ones deploying agents hardest internally, so part of that 50% is coming from the leading edge. Your customers will get there later. They will still get there.

Issues With a Pull Request Attached Grew 7x Since January

Volume is easy to fake. An agent that files 400 tickets a day produces a spam problem and calls it productivity.

Linear’s second data point is that since the start of 2026, issues with a pull request attached by someone in engineering, product, or design grew sevenfold. Work isn’t just being created, it’s being closed with code attached. The loop completes.

If you’re building anything with agents in it, track both: volume created by agents, and completion rate on that volume. The first number can go up every month while your product gets worse.

Atlassian Publishes a Growth Rate Where Linear Publishes a Fraction

So is this a Linear phenomenon or a category phenomenon? I went through what the direct competitors reported in their most recent quarters.

Sources: Linear company blog (Aug 26, 2026); Atlassian Q4 FY26 shareholder letter and earnings release (Aug 6, 2026); monday.com Q2 2026 results and earnings call (Aug 10, 2026); Asana Q1 FY27 results and earnings call (May 2026); ClickUp company announcements.

Atlassian’s Q4 FY26 letter has the closest thing to a comparable disclosure. Jira work items and Confluence pages generated through their MCP server are up nearly 4x from the prior quarter. Monthly active users of the MCP server and Teamwork Graph CLI more than doubled in the quarter to surpass 1 million, with total MCP calls up more than 400%. Mike Cannon-Brookes wrote that agents are contributors to the graph, not just consumers of it.

Directionally that’s the same shift. The difference is the shape of the number. Atlassian gave a growth rate off an undisclosed base. Linear gave composition.

Growth rates are the easier number to publish. Up 4x quarter over quarter could be 2% of Jira work items going to 8% and it would be the same headline. Composition can only be published once you’re actually there. Atlassian has every incentive to say “X% of Jira work items are now agent-created” if that number is impressive, and a much larger surface to measure it on. They said 4x instead.

monday and Asana didn’t publish either version. Both reported AI products at 17% of net new ARR, separately and in roughly the same quarter, which is about where AI monetization sits in mid-market work management right now. monday published activity totals instead of composition: more than 1.7 million agent interactions, 98 million AI block actions, roughly 3 million Sidekick conversations and more than 180,000 Notetaker hours since launch. Cumulative-since-launch counts with no denominator.

When a company has the composition number and it’s good, they publish it. Linear did.

98% of Atlassian’s MCP Users Were Also Active in the Jira UI That Month

The fear a year ago was that agents would consume the system of record through an API, the UI would empty out, and seat revenue would go with it.

Atlassian reported that 98% of MCP users were also active in the Jira UI in the same month. Humans and agents working the same records in the same system. Linear’s version of the same finding is the sevenfold growth in issues with a PR attached by a human in engineering, product or design.

Atlassian also put a number on the commercial effect: MCP adopters expand paid seats faster and grow ARR at 2x the rate of non-adopters. Rovo adopters grow ARR more than 2x faster and complete 20% more Jira work items than non-adopters. Two independent companies, one at $100M and one at $6.6B, reporting that agent usage correlates with account expansion.

177% vs 109% vs 97%

Linear held 177% net revenue retention at $100M+ ARR through the exact period agents went from 3% to 50% of created work. monday.com is at 109% net dollar retention, 115% in the $100k+ cohort. Asana is at 97%, which they highlighted as improving for a fourth consecutive quarter, which tells you where it was.

177% at that scale is top decile. It means the average account nearly doubled its spend while half the input to the product stopped being human.

At SaaStr we run production ops with 3 humans and 20+ agents. Our own tooling spend went up, not down, when we made that switch. The agents consume more of everything: more API calls, more storage, more records, more compute, more seats in some tools where we had to give agents their own identity. Consumption follows work, and agents do a lot of work.

Atlassian Grew 28% at $6.6B While monday Cut 20% of Its Staff

The AI-disruption story for this category was supposed to be that the incumbent gets eaten. The last quarter showed the opposite.

Atlassian closed FY26 with revenue up 28% to $1.77 billion, cloud revenue accelerating to +31%, subscription ARR of $6.6 billion up 23%, RPO up 44% to $4.8 billion, and its first GAAP-profitable quarter at a 12% operating margin. The stock jumped more than 35% after hours. Record quarter in $1M+, $3M+ and $5M+ ACV deals, with $5M+ ARR customers up more than 70% year over year. Cloud growth accelerating at $6.6 billion in ARR, 25 years in, is the most unusual thing in this entire comparison.

monday.com grew 22% but guided Q3 to 16-17%, cut roughly 20% of its workforce for about $100 million in annualized savings, and has seen its stock fall 63% over the past year. Asana is guiding to 8-9% growth for the year with a 2-point drag from its PLG motion and bought StackAI to accelerate its roadmap.

The squeeze is landing on the horizontal mid-market platforms sitting between the incumbent and the fast agent-native tools.

Jira Now Turns Issues Into Pull Requests Too

The product gap closed faster than most people realize. Atlassian shipped in one quarter: agents assignable directly inside Jira with access to goals and comment history, Claude and Cursor in Jira (assign an issue and the agent reads it, accesses the repo, opens a draft PR inside Jira’s permissions and audit trail), a Jira Coding Agent that turns work items into ready-to-review PRs, Agent Sessions to track what every agent did and what needs review, and Create with Rovo to spin up context-rich work items.
