[Kevin Jiang @jiang_kev]

We just raised $5.7M for @PolarBrowser, the AI browser that beats Anthropic and OpenAI on every major web agent benchmark.

- 4,500,000+ actions taken for users, automating sales, recruiting, and ops
- One company cancelled Clay and saves 25+ hrs/wk per person
- Team is from MIT, YC, Prod, Citadel, Jane Street, Perplexity, Modal, and Apple

100 hours of work. From 30 seconds of typing.

Everyone chases going viral, but the number that actually matters is day 30.

If you're early in consumer or prosumer, retention is the only metric worth obsessing over.

Can you get one person to come back every single day, or every week, for a month?

If you can't do that, going viral won't save you. It'll only expose you.

I've watched founders chase growth hacks before they had a product people wanted to use twice. The traffic comes in, and it leaves just as fast. Ten new users, ten gone. A bucket with a hole in the bottom, refilled by ad spend or a lucky post.

Scale amplifies whatever you already have. If retention is broken, going big just means more people finding out faster.

Resist the urge to chase impressions. Find the one user who won't stop using your product, figure out why, and build for more of them.

If you can't find that person yet, the problem isn't your marketing.

@endingwithali @polarbrowser Not us! These are public benchmarks that we measured on :)

[walid (nyc for summer) @TheWalid]

i asked polar browser why a competitor’s tiktok was doing so well

2 seconds later it analyzed all 163 videos, found the winners, broke down the exact format + duration, and told me what we could steal for our own strategy

this would’ve taken me hours 😭

[Kevin Jiang @jiang_kev]

Try out @polarbrowser !

[Nam Dao @namdao2000]

Got $1742.40 USD refund after 1 promoting @polarbrowser to dispute a loom (Atlassian) surprise bill e2e holyyy has to be the best AI browser tool

[Kevin Jiang @jiang_kev]

This is @PolarBrowser's ARR with 3 people.

Now, we’re hiring a founding engineer and designer to multiply a billion knowledge workers.

We’re obsessed with problems like:

→ How do you build systems that scale agents to automate the company? One thing more important than building Polar is building the company that can build Polar

→ How do we design a browser a billion knowledge workers love using every day? ChatGPT and Claude weren’t built for delegating 10 hours of browser work

→ Polar takes millions of actions a week. How do you create a high-signal agent to automatically triage trajectories, analyze rollouts, extract insights, and self-improve a self-improving harness?

See our full problem list: https://t.co/LDygLHDKsK

If interested, email [email protected] with the 2–3 most extraordinary things you've done.

[Kevin Jiang @jiang_kev]

@HeyClos @polarbrowser Will take a look! Are you on Mac or Windows?

[Kevin Jiang @jiang_kev]

@SSAudio @polarbrowser You should give it a try! If you have lots of work that you want AI to do for you, a lot of our users have found Polar to be a significant upgrade

If you're looking for an AI browser mainly for chatting w/ tabs, then Comet is better

[Kevin Jiang @jiang_kev]

Today, we're launching @PolarBrowser for Windows.

The AI browser that beats Anthropic and OpenAI on every single major web benchmark. Now it's on the other 70% of desktops.

When I was working on Comet at Perplexity, I think Dia was the only AI Browser that couldn’t take any actions for users

And I think they still can’t. I don’t think Dia belongs in the category of AI Browsers if it can’t click, type, and scroll on websites for users

[Josh Miller @joshm]

ChatGPT’s Atlas browser was sunset today. Perplexity’s Comet browser is in zombie mode.

When we started @browsercompany nobody cared about browsers, then everyone did (copying Dia), then everyone bailed.

Yet I’ve never felt more confident browser : AI :: phone : smartphones.

[Kevin Jiang @jiang_kev]

@SukritGanesh @polarbrowser Awesome to hear! What do you love about it the most?

[Kevin Jiang @jiang_kev]

@lpbangun @polarbrowser If you don't do a lot of browser tasks every day (e.g. sales, recruiting, ops, growth, marketing), especially long-running, complex ones, then you won't find Polar to be useful for you right now!

[Kevin Jiang @jiang_kev]

@AdamIAchebe @diabrowser yep, very much agree here

[Kevin Jiang @jiang_kev]

this confusion explains why @diabrowser struggled to go more mainstream. they didn't understand what problems AI agents actually solve

and they ended up building a "solution in search of a problem"

mass consumers do not need AI agents to help them scroll social media, watch netflix, or read articles

ai agents are useful for getting work done. that's different than what mass consumers want

so products like ai browsers should be targeted towards work use cases first before trying to go into mass consumer. which is exactly what we're doing with @polarbrowser

[Josh Miller @joshm]

Hot take… isn’t it kinda crazy that nobody is really using AI Agents? I don’t mean software engineers or AI early adopters. I mean “college friends talking about it in group chat,” the feeling you got when everyone started using Instagram or TikTok.

These frontier AI models are *insane* (as are the harnesses & tool calls & the like). And every large tech co has an AI agents platform, not to mention all the YC startups doing vertical agents. Yet all of your friends and family outside of tech — who spend all day staring at their iPhones and get paid to work in browser tabs — don’t really care or find themselves using any AI agents yet.

Yes ChatGPT, Claude, etc. are extremely popular… but if you look at the engagement data the vast majority of people are still using these aI chat tools like a glorified Google + Grammarly. That’s why the AGI labs are all pushing desktop apps for Codex, Cowork, etc. so hard to non-technical ppl. And yes exceptions for lawyers and customer service but even those have some asterisks and exceptions to rule.

Look I’m not saying the ChatGPT moment for AI Agents is not coming… it most definitely is! Remember we pivoted from Arc to Dia precisely because we believe computing is going to be radically reimagined around these AI primitives. No doubt. But that’s my point: it’s just so surprising it hasn’t happened yet because all of the tech you’d need is there.

Again if you stop for a second and think about it… for all the press and money and hype and models and crazy ARR numbers… this “AI Agent” moment does not *feel* like the other breakthrough tech moments we’ve lived through (e.g. think the shift to Stories via Snapchat & Instagram, or shift to on-demand via Uber/Airbnb/Doordash).

Which is a long way of saying: if you can figure out the answer to “why” most people don’t care about AI agents yet (and have no enduring interest in using them) — especially since the models and harnesses are here and ready — the answer to that question will allow you to capture a lot of marketshare and make a lot of money in 2027.

Theoretically, the tech is ready for AI Agents to totally transform how we work and live our lives… but alas the general public dgaf… that’s the generational puzzle to solve for the next 12 months for anyone not working on the models themselves.

Our @PolarBrowser launch video got 1,000,000+ views and grew our ARR by 60% in 1 week

This is how @osmo_studio's entire team used Polar to make Polar's video

1. The night before the shoot, Polar sent out deal memos and talent releases while the team slept

2. It sourced crew and locked logistics before film day

3. It pulled visual references for the pitch deck and shot lists

Polar is an AI browser that actually does work for you: research, sales, recruiting, ops, and more

You can get 100 hours of work from 30 seconds of typing. So far, 4.5M+ actions have been taken for users, with 1 company saving 25+ hrs/wk per person (& cancelled Clay)

@GoatForever97 @polarbrowser thank you! that's what we specialize in. please share it with your friends too

[Kevin Jiang @jiang_kev]

@neronz5 @polarbrowser yes! it can use your browser and any site you use

[Kevin Jiang @jiang_kev]

@Tana_Labs @polarbrowser yes, and harder tasks too!

[Kevin Jiang @jiang_kev]

@leviath666 @polarbrowser please let us know how you like it :)

[Sam Altman @sama]

i would rather be an optimist and work hard than a pessimist posting about why things won't work.

it's much more difficult and the most likely path is failure, but society fails if people don't try.

no amount of "it will never work" essays will drive society forward.

[Kevin Jiang @jiang_kev]

@codymclain @polarbrowser agreed, making users happy is our number one priority!

[Kevin Jiang @jiang_kev]

@yanliudreamer @polarbrowser sharp insight! that's why we chose the browser as the interface to knowledge work and forked chromium. this has allowed us to add an additional layer of personalization too with the browser context.
