The Best LinkedIn Growth Hacking & Growth Marketing Experts to Follow in 2026

Growth hacking has had an image problem since it was named. The phrase conjured viral loops, referral spam, and dark-pattern onboarding — shortcuts that worked once and then got copied into uselessness. The practitioners who have lasted in the discipline have moved well past that: they run structured experiments, obsess over retention before acquisition, and publish the data from their failures as often as their wins.

LinkedIn's growth community is smaller than Twitter's was at its peak, but the signal-to-noise ratio is higher. The people listed in this guide are working growth practitioners at significant scale — not consultants selling courses on growth hacking frameworks that were current in 2018. They post what they're actually testing, what the numbers showed, and what they're thinking about next.

This guide covers growth across five areas: viral and network-effect growth, product-led growth, growth modeling and analytics, acquisition experimentation, and retention and activation. Each section identifies who to follow and why their specific perspective is worth adding to your feed.

How We Selected These Experts

Every expert in this guide meets three criteria: they post consistently with original thinking rather than recycled tactics; they have a track record of running growth at significant scale — either a company they've built, an investment portfolio they're actively working, or a growth role with real revenue accountability; and they publish specifics — experiment results, retention data, acquisition benchmarks — rather than staying in the safe territory of general growth principles.

Viral Growth & Network Effects

Network effects and viral growth are the rarest and most durable growth mechanisms available to a product — and the most frequently misunderstood. These experts have built their careers on understanding the mechanics of how products grow exponentially rather than linearly, and they share that thinking with a depth that most growth content doesn't approach.

Andrew Chen

General Partner at Andreessen Horowitz and author of The Cold Start Problem — wrote many of the foundational essays on viral loops, network effects, and growth channels that the entire industry now treats as gospel. His LinkedIn posts reflect his current vantage point: investing in companies trying to build network effects in 2026, where the playbooks that worked for Dropbox and Airbnb need significant revision. He is particularly worth following for his thinking on how AI changes the dynamics of network effects — whether AI-generated content breaks or strengthens them, and what new moats look like when content is infinite.

Follow him for the long-arc thinking that most day-to-day growth content doesn't make time for.

Casey Winters

Chief Product Officer at Eventbrite (previously growth at Pinterest and Grubhub) — one of the clearest practitioners of network-effect product strategy on LinkedIn. His posts on how to diagnose whether a product actually has network effects versus just benefits from having more users, how to build the supply side of a marketplace before the demand side, and how growth strategy has to change at different company stages are some of the most rigorous publicly available content on the subject. He is particularly valuable for product and growth leaders at marketplace or platform companies.

Product-Led Growth

Product-led growth has moved from a VC talking point to a mainstream GTM motion, and the LinkedIn community has grown with it. The experts listed here have built or advised PLG programs at companies where the model genuinely worked — and they're honest about where it doesn't.

Elena Verna

Growth advisor and former VP Growth at SurveyMonkey and Amplitude — one of the most influential voices on product-led growth on LinkedIn. Her posts on PLG mechanics are unusually specific: what activation metrics actually predict retention, how to structure the hand-off between product-qualified leads and sales, and when a company should run PLG alongside sales-led rather than instead of it. She is particularly valuable for growth and product leaders at B2B SaaS companies evaluating or implementing PLG, because she addresses the operational realities that most PLG framework content skips entirely.

Lenny Rachitsky

Creator of Lenny's Newsletter — the most widely-read product and growth publication in the industry, and his LinkedIn reflects the same quality. His annual benchmarks on retention, engagement, activation, and growth rates are the most-cited data in the SaaS world, and his posts break down what those benchmarks mean for how you should be thinking about your own product. He is particularly useful for growth practitioners who need to contextualize their metrics against a reliable external benchmark — "is our 30-day retention good or bad?" is a question his data answers better than any other public source.

Kieran Flanagan

Ex-SVP Marketing at HubSpot and now advisor and investor — posts the clearest content on how to build and evolve a GTM motion at scale. His posts on how HubSpot's PLG model evolved from a product-qualified lead experiment into the company's primary growth engine, what that teaches you about when to invest in PLG versus sales-led, and how AI is changing the acquisition economics of product-led companies are unusually substantive for a growth topic that often gets reduced to surface-level frameworks.

Growth Modeling & Analytics

Growth without measurement is just activity. The experts in this section have built their careers on the quantitative foundations of growth — how to model a growth system, what metrics actually predict future performance, and how to avoid the measurement traps that make growth teams look busy while the business stalls.

Brian Balfour

CEO of Reforge — the most rigorous growth educator working today, and his LinkedIn content reflects the same depth as Reforge's curriculum. His posts on growth models — specifically how to identify the dominant growth loop driving your business, how to diagnose when a loop is breaking, and how to build compounding growth rather than linear acquisition — are the foundational reading for anyone serious about growth as a discipline. His content on why most growth teams confuse tactics with systems, and why that confusion is the primary reason growth investments stall after the first twelve months, is particularly valuable for anyone building or rebuilding a growth function.

Hiten Shah

Co-founder of FYI and Crazy Egg — one of the most consistent and practically-oriented growth voices on LinkedIn. His posts on product analytics, SaaS metrics, and how to use data to make better product and growth decisions are grounded in building, operating, and investing in dozens of SaaS companies over two decades. He is particularly useful for growth practitioners who are trying to build an analytics foundation for their program rather than just running individual experiments without a coherent measurement framework.

Acquisition Experimentation

Growth experimentation on the acquisition side is where most growth programs start — and where the most useful tactical content lives on LinkedIn. The experts in this section share real experiment results across acquisition channels and the thinking behind how they prioritize what to test.

Sean Ellis

Coined "growth hacking" in 2010 and has spent the fifteen years since stress-testing the concept against how growth actually works at scale. His LinkedIn posts have evolved from growth hacking tactics to a more fundamental question: how do you build an organization that can sustain growth rather than just produce growth spikes? His content on the "must-have survey" — asking users how they'd feel if they could no longer use your product as a proxy for product-market fit — and how the answer should drive all subsequent growth investment is worth reading for any early-stage team.

Follow him for the historical perspective that most growth content, focused on the current platform environment, doesn't have.

Retention & Activation

Retention is where growth programs either compound or collapse. A leaky bucket that needs constant acquisition to maintain flat revenue is not a growth program — it's damage control. These experts have made retention and activation their primary focus and share the mechanics in public.

Wes Bush

Founder of ProductLed and author of Product-Led Growth — the most accessible voice on the activation and retention mechanics of PLG on LinkedIn. His posts on what the first-run experience actually needs to accomplish — not just "showing the value" but getting users to a specific moment where the product has earned ongoing use — and how to diagnose activation problems before they become churn problems are practically applicable across both consumer and B2B products. He is particularly useful for growth practitioners working on onboarding, where most teams know the problem but underestimate what the fix requires.

How Growth Marketers Should Build Their LinkedIn Presence

Growth marketers have a structural content advantage on LinkedIn: they work with data other practitioners don't have access to. An experiment result — the hypothesis, the test, the outcome, the next question — is more differentiated content than any growth framework, because it's both specific and yours. The accounts in this guide that have built the most engaged professional followings all share real experiment data, not just advice about running experiments.

The practical version: document your growth work as you do it. An onboarding experiment that failed is a better LinkedIn post than a onboarding best practices list. An acquisition channel that didn't scale the way you expected, and the data that showed you why, is worth more to your professional reputation than a summary of someone else's case study.
