How Dharmesh Shah Turns Building in Public Into 1.2M Followers

We analyzed 100 of Dharmesh Shah's most recent posts to reverse-engineer how HubSpot's co-founder built a 1.2M-follower audience with mostly plain text: the BREAKING NEWS format, the build-in-public loop, and the six content pillars behind it.

01

Dharmesh wins with ideas, not production value

He is the co-founder and CTO of a public company with a million-plus followers, and 70% of what he posts is unadorned text. The reach comes from the thinking, not the format.

Dharmesh Shah co-founded HubSpot in 2006, took it public, and is still its CTO. He also builds constantly on the side: Agent.ai (2.5M users), HubCode, HubGrader, a simple.ai newsletter with 2M+ subscribers. His LinkedIn is where all of that thinking gets aired first, usually as a plain-text post typed in the same terminal-brained voice he codes in. We read 100 of his most recent posts to map how a builder, not a broadcaster, grew past 1.2M followers.

His whole method has a name he would probably resist, but it fits. Building in public is narrating what you are making and learning in real time, so your audience becomes your first users and your feedback loop. Dharmesh does not wait for a launch to be polished. He posts the tinkering, asks what people think, and ships based on the replies.

The broadcast account

Waits for the finished launch, posts the press-release version, and treats the audience as a megaphone.

Dharmesh the builder

Posts the half-built idea, asks 'is this a good idea?', and lets the comments shape what he builds next.

The core bet
A million people do not follow Dharmesh for slick video. They follow him for the take only an insider building the thing can give. Ideas are the production value.
02

Plain text, outsized reach

The numbers say something counterintuitive: the guy with the biggest audience mostly writes text, and it works.

Across the 100 posts we analyzed, Dharmesh averages 514 reactions a post and clears 1,000 reactions 17 times. His comment-to-reaction ratio is 18.9%, roughly three times the typical LinkedIn norm. But the real story is the format mix.

Plain text70%
Image28%
Video2%
Format mix across 100 posts. He writes text 70% of the time, yet his rare videos (avg 1,291 reactions) and images (710) out-punch his text (415). The ideas travel regardless.

Read that twice. He could clearly lift every post by adding a graphic or a video, and he mostly does not. He optimizes for volume and speed of thought over polish, because his edge is the thinking.

The lesson in the mix
You do not need a production studio to grow. You need a point of view worth reading. Format is an amplifier, not the substance.
03

Six pillars, from news bulletin to human

His feed looks like a stream of consciousness and is actually six repeating pillars, each with its own job.

BREAKING NEWS curation
Authority

An AI or industry development, plus the insider take only he can give.

Build in public
Builder

Current Status updates on HubCode, Agent.ai, and HubGrader.

The agentic thesis
Vision

Where B2B software is heading: agents that run your product, not just use it.

HubSpot milestones
Brand

Launches, anniversaries, and unabashed love for the company.

Founder wisdom
Teaching

Mantras and lessons from a 30-year career, kept short.

The human behind the builder
Personal

Piano streaks, chess losses, and proof he is not a bot.

1. BREAKING NEWS curation

BREAKING NEWS: Anthropic launches new Fable 5 Model -- and US Government makes them take it down. This is really weird.

Why it works: Why it works: he wraps a dense AI story in a news-bulletin frame, then adds a take with the credibility of someone who ships AI daily.

2. Build in public

@dharmesh ·
I created an AI agent on Agent .ai that turns blog posts into Avatar videos. The problem I'm trying to solve: I write a lot of content, but most of it reaches only a subset of its potential audience because many people prefer video.

Why it works: Why it works: he shows the thing he built, names the exact problem it solves, and invites feedback. The build is the content.

3. The agentic thesis

Dharmesh Shah
@dharmesh ·
Every B2B software company is (or should be) building an agentic version of their product. One that can be used programmatically by agents, not just interactively by humans.

Why it works: Why it works: a clear, quotable thesis that names the shift before most people see it. Prediction posts get saved and shared.

4. HubSpot milestones

I have spoken at my last INBOUND conference. If you've known me or HubSpot for any period of time, you've probably heard of the INBOUND conference. You may have even attended (thank you!).

Why it works: Why it works: a bittersweet hook ('my last') on a routine rebrand announcement, so a company update reads like a personal moment.

5. Founder wisdom

My mantra across my 30+ year career: Dream big, iterate small. That has served me very well and has stood the test of time.

Why it works: Why it works: a short, memorable maxim earned over decades. No thread, no framework, just one line people can carry.

Lest you think all I do is work/code, here are other things I've spent time on today: 1) Reading the book "There Is No Antimemetics Division". Thanks to Sherwin Wu for recommending it on Lenny Rachitsky's podcast.

Why it works: Why it works: a deliberate break from the AI firehose. The chess losses and piano streaks make the authority feel like a person.

Three hooks that make dense ideas feel light

Dharmesh writes about heavy technical topics, and yet the openers feel breezy. That is by design. He uses a small set of familiar frames.

Dharmesh's three go-to hook frames
BREAKING NEWS: [an AI or industry development] ... then his insider take
Woo hoo! [a HubSpot or personal launch worth celebrating]
Current Status: [what he is tinkering on right now]

The trick: a familiar frame (a news bulletin, a cheer, a status line) that makes a dense idea feel like a bite, not a lecture.

The frames repeat because they work. Each one sets an expectation the reader can process in a second:

  • The news bulletin: 'BREAKING NEWS: Andrej Karpathy Joins Anthropic.' He curates the moment, then adds the take only he can.
  • The cheer: 'Woo hoo! HubSpot turns 20 years old today!' Genuine, uncynical enthusiasm as a hook.
  • The status update: 'CURRENT STATUS: Tinkering on a new idea... Hub Code.' An open invitation to watch him build.
  • The confession: 'This might be the SCARIEST and/or CRAZIEST thing I've done in years.'
  • The one-word cold open: 'Goosebumps.' One word, then the story.

The through-line is that a hook is a promise about how much effort the post will cost the reader. Want to draft your own in this style? Try our free hook generator, and our guide on how to write LinkedIn hooks breaks the patterns down further.

The build-in-public flywheel

The pillars and hooks feed one loop that turns Dharmesh's tinkering into an audience and that audience into users for the things he builds.

  1. 1
    Tinker in public
    Posts Current Status and sneak-peek updates while building HubCode, Agent.ai, and HubGrader.
  2. 2
    Ask for feedback
    'Feedback is a gift.' A like or a comment shapes what he builds next.
  3. 3
    Launch to the same crowd
    The people who watched him build become the first users on day one.
  4. 4
    Repurpose one idea everywhere
    A single write-up becomes an avatar video, a long-form post, and a short update.
loops back to the top
Result: 1.2M followers and a pipeline of tools that all feed the HubSpot ecosystem.

That last step is the tell. Dharmesh literally built an agent to turn his written posts into avatar videos, because, in his words, 'I write a lot of content, but most of it reaches only a subset of its potential audience.' That instinct is pure capture-first: write the idea once, then reshape it for every audience. It is exactly what CaptureFlow does. CaptureFlow is an AI content agent that turns your expertise into weeks of on-brand content for every platform, trained on your voice, so one captured idea becomes a LinkedIn post, an X thread, a short video, and a carousel without you rebuilding it five times.

Why the loop compounds
Building in public means the marketing IS the product development. Every 'what do you think?' post is research, distribution, and a launch list in one.
06

The humble builder: his voice rules

For a founder of his stature, the voice is strikingly low-ego: curious, generous, and allergic to hype.

Dharmesh always
  • Writes in plain, conversational, terminal-brained text
  • Shares the messy work-in-progress, not just the launch
  • Credits people by name and calls feedback a gift
  • Adds a genuine 'Woo hoo!' or a self-deprecating aside
  • Explains the technical idea for 'mere mortals'
Dharmesh never
  • Leans on polish or production to carry a weak idea
  • Postures as the smartest person in the room
  • Hypes without a caveat or a disclosure
  • Hides the failures (the lost chess games stay in)
  • Talks down to a reader who is newer than he is

It is a voice built for the founder building in public, the same lane Anton Osika runs in our Lovable teardown. The lesson both prove: sharing the build, humbly and often, beats announcing the finished thing.

The humility hook
'Sorry for the self-indulgent post.' Dharmesh often undercuts his own big moments. The modesty is disarming, and it makes the wins land harder.

Steal Dharmesh's build-in-public playbook in 30 days

You do not need a public company or a million followers. You need something you are building or learning, and the willingness to narrate it.

1Week 1 · Open the workshop
  • Pick one thing you are building or learning right now
  • Post a 'Current Status' update on it, half-finished is fine
  • End with a real question and ask for feedback
2Week 2 · Curate with a take
  • Find one development in your field this week
  • Post it as 'BREAKING NEWS' plus the take only you can give
  • Keep it plain text. Speed and clarity over polish.
3Week 3 · Teach one lesson
  • Write one short mantra from your own experience
  • No thread, no framework, just one line worth carrying
  • Add one human post so you are not only your work
4Week 4 · Repurpose the idea
  • Take your best post and reshape it into a video or carousel
  • Share the same idea where a new audience will see it
  • Turn the people who engaged into a launch list
The one thing to copy
Not the follower count. The habit of posting the build before it is done. That is what turns an audience into collaborators.

Dharmesh does the repurposing by hand, and even coded his own agent for it. If you want the same one-idea-everywhere output without building the tooling yourself, that is what CaptureFlow automates. See pricing to start turning your own work-in-progress into weeks of content.
