Community-Led Growth: How Duolingo, Figma, Notion, and HubSpot Scaled With Community

Communities have always shaped how products spread. What has changed over the past few years is community-led growth: companies now deliberately operationalize community engagement as a growth strategy, using it to improve their product, drive business results, and give users a reason to stay.

Duolingo, Figma, Notion, and HubSpot are four of the clearest examples of community-led growth in practice, and each of them scaled in a different way. This article defines community-led growth, contrasts it with product-led growth, breaks down what the four companies actually did, and ends with a five-step framework for building your own strategy.

What is community-led growth?

Community-led growth is a go-to-market strategy in which a company's user community, not its sales or marketing teams, becomes a primary driver of acquisition, retention, and product feedback. Users answer each other's questions, create content, champion the product, and shape the roadmap, which compounds growth over time.

The distinction matters because community-led growth is a structural choice, not a channel. As BuiltIn puts it, the difference lies in “valuing community as a core piece of your business” rather than bolting a forum onto your product. A community that sits at the core of the business feeds product decisions, absorbs support load, and produces advocates. A forum that sits at the edge of the business produces threads.

Community-led growth also does not replace your product motion. It works as a catalyst for it. The product gives users a reason to arrive, and the community gives them a reason to stay, participate, and bring others with them. That is why the strongest examples of community-led growth, including the four below, are companies with strong products that treated community as infrastructure rather than as a campaign.

Community-led vs product-led growth

Product-led growth uses the product itself as the main engine of acquisition and conversion, while community-led growth uses the relationships between users as the main engine of retention and advocacy. Most companies that succeed with one eventually layer in the other, because the two motions compound each other.

The practical takeaway is sequencing. Product-led mechanics get users in the door efficiently. Community-led mechanics raise the switching cost of leaving, because users who would abandon a tool rarely abandon their people.

How we chose these four examples

We picked four companies that made community a deliberate part of how they grow, each showing a different mechanism (self-expression, champions, sequencing, and operations), with a named leader quoted on the approach. Outcome figures come from the companies’ own filings, shareholder letters, and announcements, or from named press coverage, and each carries a date so you can check it. Disclosure: social.plus publishes this blog and builds the kind of infrastructure discussed here.

Duolingo: community as the engine behind 140 million monthly users

Duolingo built community into the core of its learning product, and the scale followed. According to Duolingo’s Q2 2026 shareholder letter (August 2026), the app now reaches 140.6 million monthly active users and 58.7 million daily active users, with daily actives up 23% year over year.

Community shaped Duolingo’s growth long before those numbers. Its early course catalog was built with volunteer contributors, and its discussion spaces let learners clear up doubts and shape the courses they wanted. That contributor-driven foundation carried the company through its first decade, and the machinery it built on top of that foundation still compounds: in April 2025, Duolingo launched 148 new language courses in a single release, more than doubling a catalog that had taken twelve years to build (Duolingo, 2025).

Laura Nestler, Duolingo’s then-Global Head of Community, who later became Reddit’s VP of Community, described the role community played in the company’s scale-up: “Community for Duolingo is not just a fuzzy buzzword, it is the mega highway that powers what we do, why we do it, and who we do it for.”

The lesson from Duolingo is about self-expression. When users can suggest changes, contribute content, and talk to each other inside the product, engagement stops depending on push notifications and starts depending on belonging.

Figma: champions and collaboration, from $10B startup to public company

Figma turned collaboration into both its product mechanic and its community strategy, and that combination carried it to the public markets. The company listed on the NYSE under the ticker FIG on July 31, 2025, priced at $33 per share and raising roughly $1.2 billion, and its stock more than tripled on the first day of trading (CNBC, 2025). Community reach was central to that story: Figma reported 13 million monthly users in its IPO filing, and around two-thirds of them are not designers (Figma S-1, 2025).

The community machinery behind that reach is deliberate. Figma runs a program of Designer Advocates, practitioners who create best-practice content, anchor community spaces, and carry feedback back into the product. Amanda Kleha, Figma’s then-Chief Customer Officer (she held the role from 2018 to 2023), explained the mechanism: “In our communities, the Designer Advocates are key for us, because they create best practice content and bring in key feedback from the community which influences the features we build.”

The lesson from Figma is about champions. A community scales when identifiable people anchor it, connect with members horizontally, and give the company a trusted feedback channel that no survey can replicate.

Notion: a champions network that helped reach 100 million users

Notion made its most engaged users the distribution channel. The company built a network of champions across different organizations who exchanged templates, ideas, and best practices, and it gave them direct access to the people building the product. Notion announced it passed 100 million users in 2024 (Notion, 2024), five years after it was valued at $10 billion as a private company.

Olivia Nottebohm, Notion’s then-Chief Revenue Officer, who is now Chief Operating Officer at Box, described the approach: “We created a community of champions from different companies who were all working on the Notion platform. They could exchange ideas and best practices, and most importantly, we granted them access to ask thought leaders about the product and what they thought should come next.”

The lesson from Notion is about sequencing. Lead with the product, because the product attracts the right users and defines what the community talks about. The community then becomes the reason those users stay and the mechanism by which they recruit their teams.

HubSpot: a staffed community that feeds the product

HubSpot treats its community as an operated system, not a self-running asset. Its long-running support community gives users a place to ask questions, find answers, and engage with professionals worldwide, and the ideas surfaced there feed directly into product development. The company summarized its philosophy in two words: better together.

Shana Sumers, then one of HubSpot’s community leaders and since departed from the company, described the operating standard: “We want to make sure that people are feeling welcome in the community, that they know how to navigate it, and that they feel seen. These are the basics to make sure that our communities are running as positively as they can.”

The lesson from HubSpot is about operations. No community runs on its own, even when members have every tool to do so. Dedicated community staff, clear programming, and active moderation are what keep an online community compounding instead of decaying.

Four community-led growth examples at a glance

Each of the four companies proves a different part of the community-led growth thesis. The table below summarizes the tactic, the outcome, and the transferable lesson.

Kickstarting your community-led growth strategy

Community-led growth is a system you build deliberately, not a switch you flip. The four examples above all pair a strong product with sustained investment in community operations, and the framework below turns their playbooks into five concrete steps.

Anchor the community inside your product. Duolingo’s community works because it lives where the learning happens. Building your community in-app, on infrastructure you control rather than on a rented platform, keeps engagement data, moderation, and monetization in your hands. social.plus provides the community infrastructure, SDKs, and UIKit to embed social spaces directly into your app.

Define the jobs your community does. Pick the outcomes that matter first: peer support that deflects tickets, feedback that shapes the roadmap, or advocacy that drives referrals. Tie each job to one core metric, such as active participation or contribution rate, so the community is accountable to the business.

Recruit and empower champions. Figma’s Designer Advocates and Notion’s champions network show that a small set of visible, trusted members carries most of a community’s culture. Identify your most engaged users early, give them status and access, and let them anchor the spaces you open.

Staff it before you scale it. HubSpot’s lesson is that no community runs on its own. Budget for community managers, moderation, and regular programming from the start, because meaningful participation is built over time, not unlocked at launch.

Instrument, learn, and reinvest. Measure participation, retention, and the pipeline of ideas moving from community to roadmap, then reinvest in what works. The ROI of an in-app community becomes visible when you can trace engagement to retention in your own data.

If you are ready to build community into your app rather than around it, talk to our sales team or review social.plus pricing to see what the infrastructure looks like in practice.

Frequently asked questions

What is community-led growth?

Community-led growth is a go-to-market strategy in which a company’s user community becomes a primary driver of acquisition, retention, and product feedback. Instead of relying only on sales and marketing, the company invests in spaces where users support each other, create content, and advocate for the product. Duolingo, Figma, Notion, and HubSpot are four widely cited examples.

What is the difference between community-led growth and product-led growth?

Product-led growth uses the product itself, through self-serve onboarding and free tiers, as the main engine of acquisition. Community-led growth uses relationships between users as the main engine of retention and advocacy. The two motions complement each other: the product brings users in, and the community gives them a reason to stay.

How do you measure community-led growth?

The core metrics are active community participation, member retention, and the volume of community activity that maps to business outcomes, such as support questions answered by peers or product ideas shipped from community feedback. Comparing retention of community participants against non-participants is the most direct way to show impact. Over time, referral and word-of-mouth acquisition attributable to the community indicates whether it lowers acquisition costs.

Which companies use community-led growth?

Duolingo built its early course catalog with volunteer contributors and reached 140.6 million monthly active users by Q2 2026. Figma runs a Designer Advocates program and listed on the NYSE in July 2025. Notion built a champions network and passed 100 million users in 2024, and HubSpot operates a staffed support community that feeds its product development.

How do you start a community-led growth strategy?

Start by anchoring the community inside your product on infrastructure you control, then define the specific jobs it does for the business, such as peer support or product feedback. Recruit champions from your most engaged users and staff the community with dedicated moderation and programming. Meaningful participation builds over time, so instrument the community from day one and reinvest in what demonstrably drives retention.
