Scott Wu: Coding IDEs and AI agents must share persistent codebase context
“The really good coding IDE products, you know, the tool that you're kind of like sitting in and like using to look at the code itself versus the agent product, which is kind of that almost the engineer that you can delegate. You obviously want this to be very …”
Cognition completed the Windsurf acquisition over a single weekend
“We got in touch with the Windsurf team that evening, so it was Friday evening, and then basically over the course of that weekend we,
Worked out the entire acquisition together. So, by Monday morning, we had the announcement ready to go.”
Cognition Had $70M–$80M ARR and 35–40 People When Buying Windsurf
“Cognition at the time was all of 35 or 40 people and we had a meaningful business with, you know, real traction. We were doing in the range of 70 or eighty million of revenue run rate at the time but it was a very small team. Windsurf, on the other hand becaus…”
Malde: SWE-ONE beat frontier models via user-signal post-training
“And this was the kind of major unlock for the company as well, is we had all this massive data. We were able to post train on all of that user signal and now beat the frontier.”
Malde walked away from $2B DeepMind acquisition to found Trajectory.ai
“Obviously the acquisition was for two billion dollars and went over to DeepBind, and then I decided to give up all the acquisition money to start trajectory.”
Malde: Direct user modifications, not binary feedback, drive effective AI continual learning
“I think when people think about, like, online learning, continual learning, they'll first think of, like, accept, reject, or thumbs up, thumbs down, like some of those, like, kind of binary signals. It turns out that that's actually, like, very noisy. You can …”
Moreno: Structured Software Rollouts Far Outperformed Self-Serve Marketplaces at Windsurf
“Because six months in, companies that did structured rollouts were a lot more successful, and we ended up collecting a lot of data on this because it became part of how we sold. Then the companies that said, hey, I've got tool A, tool B, and tool C, we're gonn…”
Moreno: Enterprise AI sales requires simultaneous top-down and bottom-up pressure
“Great sales is like squeezing an orange or applying pressure from both sides. So on the one hand, do you want to go talk to engineers and like have a strong DevRel practice and really get in and like understand on the ground the way that people are working, th…”
Moreno: Windsurf prioritized partners, enablement, and data early in scaling
“Because when I got into Windsurf, outside of hiring sellers and deployed engineers, the three things that I told our CEO that I wanted to go do was hire a world-class partner person, a world-class enablement person, and a data person.”
Moreno: Windsurf invested in partner networks $40M earlier than peers
“Being able to go and build credibility and build belief in the big partners and systems integrators was something that we started doing probably forty million dollars in revenue before most companies.”
Moreno: AI developer tools rarely face build-vs-buy resistance
“The interesting thing is that where I have sat in AI, I feel like there's less of a build versus buy conversation. Like pretty quickly, people realized that they weren't going to build co-pilot or cursor or windsurf.”
Moreno deterred Windsurf executive conflicts by intentionally annoying both parties
“One of the things I used to say at Windsurf, and we haven't had to do this yet at Parallel, But I would say I don't ever want a debate or a conflict between my directs to come to me, because if it does, I will intentionally make a decision that's designed to a…”
Moreno: Windsurf Decided to Route 100% of Revenue Through Partners
“So like we made the decision to run a hundred percent of our revenue through partners.”
Wu: Cognition acquired Windsurf and shares engineers across both products
“We bought Windsurf, you know, seven, eight months ago at this point, but like, we don't have a distinction of like, oh, this person's an engineer working on Devon or this person's engineer working on Windsurf. Like a lot of the same people should be people who…”
Mirzadegan: Windsurf had the fastest growth of any Kleiner Perkins company

Derek Reimer prefers Claude Code over Windsurf's built-in AI agent.
“That's my main editor, and I actually don't use the agent functionality in Windsurf much anymore. I've kind of switched over to Claude code for that”
AI editor forks like Cursor make Microsoft's VS Code ecosystem more entrenched.
“The fact that it's open source and it's been able to be forked by, you know, Cursor and Windsurf and others to then layer on this functionality has just made it even more entrenched, I think.”
Hays: Google spent billions to acquire Windsurf's intellectual property
“They, of course Google did buy, you know, spend however many billions on, on acquiring the Windsurf IP, so not super surprising.”

Levie: AI tool makers will maintain flat pricing despite falling compute costs
“It's like, it's 20 bucks a month, it's 50 bucks a month, but we know that in 10 years from now, they'll probably be able to drive down their raw materials lower, but we won't be able to command lower prices for those things, because it's just like within a rea…”
O'Driscoll: AI reverse acqui-hires are regulatory shams leaving dead target companies
“We actually, in both of those cases, that's a pure pretense to get the government off of us, right? Everyone knows both of these companies are toast because in the case of Scale AI, in theory, Meta owns 50% of it, and in theory, their business is selling to ev…”
Vollset: Windsurf Deal Was a Massive Founder Payday Structured to Screw Employees
“The original deal, which was like a successful, holy crap, that's a big number deal was three billion. The Google aqua hire is 2.4. That's ballpark same number. So like, you got screwed as if this was a soft landing for the founders, but it was a massive payda…”
Landgraf: OpenVSX powers all extensions in Cursor and Windsurf
“And together with that, we also created OpenVSX, which I think now powers all of the extensions that you see running in Cursor and also Windsurf, which is also open source under the Eclipse Foundation marketplace for VS Code.”
Wu: Cognition recently acquired IDE tool Windsurf
“We've been going for the last year and a half, and most recently just acquired Windsurf, and so, you know, Devon, the agent in Windsurf, the IDE, but at a high level, you know, we really want to build the future of software engineering.”
Wu: Cognition's core engineering team grew from 19 to 30-35 post-Windsurf

Wu: Only a small fraction of Windsurf team took Cognition buyout offer
“Yeah, yeah, yeah, I think for us, it's you know, and most folks have been really excited to come in and do it, and only a small fraction have taken the buyout, but I think from our perspective we just want to make sure it's an opt-in, you know, situation for e…”
Masad: Claude Code competes directly with Cursor and Windsurf
“Right now, Cloud Code is, is used by developers and loved by developers, and I think they're competing head-to-head with Cursor, Windsurf, and those kind of products.”
Dylan Field: Figma does not view Cursor as a competitor

Lemkin: Cognition mandated 80-hour weeks and laid off 30% of acquired startup
“Well, I guess today, Cognition laid off 30% of the folks they bought, and they offered to buy out all the other 200 employees. They gave them a nine-month package. They told them they either had to work 80 hours a week, six days a week in the office, or they s…”
Swyx: Windsurf will stick around as an active product post-acquisition
“I think Windsurf as a product is going to stick around, and people who really like Windsurf, I mean, I was a Windsurf user for a long time we are going to keep using it because it fills a need, and like, obviously, Cognition bought it for a reason.”
Krishnan: Undetectable Backdoors in Coding Assistants Threaten Critical Infrastructure
“Interpretability is still a nascent field and you could very easily see ways where You plug a model into a cursor or windsurf and you generate a piece of code. And then two years down the road, it turns out that code had a little if statement saying, if I'm ru…”
Masad: Windsurf and Cursor compete with big tech while Replit is seen as a toy

Ramachandran: AI flows will succeed AI agents in developer tooling
“Copilots are collaborative, but can only work on small scopes. Agents can do larger tasks, but are not collaborative. Both are very useful, but we realize that this real magic will happen when the AI has the ability to be both collaborative and independently p…”
Ramachandran: Cascade goes further than any other agentic system
“This allows Cascade to be independent, but Cascade takes it further than any other agentic system. By also generating commands to be run.”
Mohan: The Windsurf Editor is a direct fork of VS Code
“It is a fork of VS Code, and yes, We do know the memes. But there wasn't a need to rebuild everything from scratch.”
Mohan: Windsurf's real value is large codebase work, not 0-to-1 apps
“We had the technology to go out and build these zero to one apps very quickly, and I think people are using Windsurf to actually do that, and it's like extremely impressive, but the real value, I think, is actually much deeper than that. It's actually that you…”
Ramachandran: Coding agents needing constant human fixes are unready for autonomy
“If the agent there has to always get human involvement to keep on fixing itself, it's probably not ready to become a full end-to-end automated system, because then we're just going to turn into a linter where, like, it produces a bunch of things and no one loo…”
Mohan: Windsurf Cascade splits planning to Claude and codebase application internally
“The high level planning that is going on in the model is actually getting done with products like the cloud, but the extremely fast retrieval, as well as the ability to like take the high level plan and actually apply it to the code base is proprietary systems…”
Ramachandran: Codeium's $10/month plan primarily covers compute costs without high margins
“And so we just created a 10 dollar a month pro plan, mostly just to cover the cost. Like we're not really like operating, I think, on a much of a margin there either, but like, okay, like just to cover us there.”
Ramachandran: Executing terminal commands in Cascade will be a huge unlock
“Vern's talked about not just suggesting the terminal command, but actually executing them. Like, I think that's gonna be a huge unlock.”

“We've had immense success getting people onto the platform, and we've been very fortunate to have the issue of being some of Anthropic and OpenAI's largest consumers.”
Hou: The future of developer tooling will eliminate copy-pasting into AI
“So we very strongly believe in a future of no copy-paste. Right? You should never have a situation where you're in a terminal, or you're in a document, or even on a website, and you're copy-pasting text into an agent. That's just not how the way the world work…”
Hou: Future AI agents will anticipate developer actions dozens of steps ahead
“In the future, we'll be looking not just one to five steps in the future, but 10, 20, 30 steps into the future. It'll be writing unit tests before you've even finished defining the function. It'll be performing code-based-wide refactors on multiple files based…”
Hou: 99% of AI editor rules file contents will be automatically inferred
“We strongly believe that having a rules file, you know, we do allow users to add a rules file, we strongly believe that a rules file is a crutch. You know, by the end of twenty-twenty-five, 99% of the things that you're gonna put in a rules file will be interp…”
Hou: Chat interfaces are a legacy paradigm being replaced by AI agents

Hou: 90% of code written by Windsurf users is generated by Cascade
“All of our users, 90% of the code that they're writing is generated with Cascade. That's an astonishing number. Autocomplete was more in like the 20, 30%.”
Windsurf aims to shift coding workflows from 80% agent to 99% agent
“And today, timelines are 80 to 90% agent, 10 to 20% human. But we're trying to build towards a future that gets the 99% agent and one percent human. We only want to ask the user for final approval.”
Hou: Windsurf's SWE-1 achieves near-frontier model results at lower cost
“And we've been able to achieve near frontier model results at the fraction of the cost, and with a significantly smaller team.”
