Distribution You Don't Pay For
Three loop types, the 1% rule, escape velocity, and why bolted-on virality never compounds
Hey there! 👋
We weren't planning on sending another one this soon, but this was too good not to share. 👀
In January 2021, a series of TikTok videos showing Notion workspace setups went so viral that Notion’s servers crashed. The company had to pause ALL feature development for six months just to scale the backend. Nobody on Notion’s team made those videos. Users made them because showing off a beautiful dashboard was a flex, like a clean desk or a color-coded bookshelf.
By 2024, 100 million users. 95% organic. $400 million in revenue. 30,000+ community-created templates. No sales team drove this. Users built things with the product and other people wanted to copy them.
That’s the most powerful growth mechanism in startups. And the thing most founders get wrong about it is thinking you can bolt it on after launch. You can’t. The loop has to be in the product’s architecture from day one. It’s not a growth hack. It’s a product decision.
Before we begin... a big thank you to this week’s sponsor: United States Tungsten
This Metal Has Already Surged 557%
Tungsten fuels everything that matters: aerospace, EVs, defense. The market is projected to hit $10 billion by 2030, and one company is positioning itself to transform the domestic tungsten supply chain.
United States Tungsten is working toward reopening a domestic recovery and processing facility through the Tungsten Queen, holding approximately 1 million tons of tungsten.
Demand is expected to surge as the U.S. rebuilds its domestic mineral supply. With critical mineral legislation accelerating and defense budgets rising, domestic suppliers have a unique opportunity to lead the market.
United States Tungsten is already in talks for government supply contracts.

Loops are not funnels
Quick distinction that matters more than people think.
A funnel is linear:
→ Acquire → Activate → Retain → Monetize → Done
A loop is circular:
→ User acts → Output reaches non-user → Non-user signs up → Acts → Output reaches another non-user → Repeats
Funnels need constant feeding. Stop spending on acquisition, funnel starves. Loops are self-reinforcing. Each cycle generates the input for the next. A funnel with 10,000 users produces 10,000 users worth of value. A loop with 10,000 users produces 10,000 PLUS however many those users bring in, who bring in more, who bring in more.
The companies at the top of every growth chart aren’t running better funnels. They’re running loops. Different mechanism entirely.
Three loop types
Not all loops work the same way. Most people lump them together as “virality” which misses the structural differences that determine how you design, measure, and scale them.
Invite loops. Product requires multiple people to deliver core value. You HAVE to bring others in. Slack is useless alone. Miro needs collaborators on the whiteboard. A Zoom call needs someone on the other end. Distribution is mandatory. Users don’t choose to invite. The product doesn’t function without it.
Design requirement: the invite has to be frictionless AND deliver immediate value to the invited person. Miro nails this by dropping collaborators straight into a shared board in the browser. No download, no account creation required to view. The invite IS the onboarding.
Artifact loops. Product creates outputs that travel to non-users and carry the brand with them. This is the “Powered By” loop and it’s maybe the most underestimated growth mechanism in SaaS.
Typeform built their entire growth engine on it. Every free-tier form has a “Powered by Typeform” footer. You fill out a beautifully designed survey, you notice the footer, some percentage click through. 80% of Typeform’s customers came from word-of-mouth or product virality. They hit $70 million ARR with 500 million+ digital interactions. And here’s the part that should make every growth team think: Typeform’s viral loop was largely untrackable. It didn’t show up as referral clicks. It showed up as direct traffic and brand search. People encountered a Typeform in the wild, Googled “Typeform,” and signed up. The virality expressed itself as brand awareness, not as a measurable click path.
ClickFunnels bootstrapped from $0 to $200 million in revenue largely on “Powered by ClickFunnels” badges at the bottom of landing pages its users built. Statuspage (later acquired by Atlassian) made the “Powered by” footer their #1 growth driver. Users saw another company’s status page, liked it, and had their own up and running in less than 10 minutes. Webflow does it with “Made in Webflow” on every free-tier site. Every website a user builds is a living advertisement.
The brilliant thing about artifact loops: users aren’t marketing for you. They’re using the product for their own purposes. The marketing is exhaust from utility. Nobody fills out a Typeform to promote Typeform. Nobody builds a ClickFunnels landing page to promote ClickFunnels. The distribution happens because the product’s output naturally travels to non-users.
Tally, the form builder, went from $0 to $4 million in revenue using a variation: embeddable forms with branding. Users create a form, embed it on their website, every visitor sees the Tally badge. Smaller scale than Typeform but same mechanic, same compound growth.
The OG artifact loop was Hotmail in 1996. “PS: I love you. Get your free email at Hotmail.” Appended to every outgoing email. Every email sent was an ad. They hit 12 million users in 18 months. The mechanic hasn’t changed in 30 years. Only the products have.
Identity loops. Product gives users something to brag about. The bragging IS the distribution. Users share for THEIR ego, not for your growth. You just happen to be the vehicle.
Spotify Wrapped is the purest modern version. Every December, every social feed fills with personalized music summaries. Nobody shares Wrapped to promote Spotify. They share it because their taste in music says something about who they are. The product generates a bragging moment so visually beautiful and personally specific that NOT sharing it feels like a missed opportunity.
Duolingo streaks work the same way. A 365-day streak is genuinely impressive. The app makes it trivially easy to screenshot and post. Users share because the streak signals discipline and ambition. Duolingo benefits, but the user’s motivation is entirely self-serving.
Strava runs. Peloton leaderboards. Language learning milestones. Fitness achievements. Any product that tracks progress or creates personal records has the raw material for an identity loop. The design question: does your product generate moments users want to display publicly not because you asked but because the moment is too satisfying to keep private?
Nubank in Brazil did something clever with a variation on identity loops. They made their credit card invite-only, with existing users as gatekeepers. Having a Nubank invite became social currency. People actively sought invitations. The exclusivity turned a financial product into a status symbol and a distribution mechanism simultaneously. The “gatekeeper” felt important. The invitee felt chosen. Both motions spread the product.
Single-player vs multiplayer: the first diagnostic
Before you pick a loop type, answer one question: does your product deliver full value to a single user, or does it require multiple people?
Single-player products (Notion, Typeform, Canva, Duolingo) work for one person alone. You can build a dashboard, create a form, or learn French without anyone else involved. Natural loops: artifact and identity. Single user creates something or achieves something that travels outward.
Multiplayer products (Slack, Miro, Zoom, Linear) require groups. Natural loop: invite. Usage literally demands more participants.
The mistake: building multiplayer features into single-player products thinking collaboration equals growth. Adding “share with your team” to a product that works perfectly alone adds complexity without adding distribution. Notion’s loop isn’t team collaboration. It’s templates. Individual users build something beautiful and share it publicly. The loop runs on single-player creativity, not multiplayer coordination.
Get this diagnosis right first. Everything else follows from it.
The 1% rule
In any platform with user-generated content, roughly 1% of users create, 9% contribute lightly, and 90% consume passively.
Your distribution loop runs on the 1%.
The 90% are the audience the loop attracts. The 1% are the engine producing the content that attracts them. Most founders design for the 90%: better reading experience, smoother consumption, nicer UI. The founders who build real loops design for the 1%: better creation tools, easier publishing, recognition, monetization.
Notion’s template gallery isn’t primarily a consumption feature. It’s a creation and distribution platform for the 1% who build templates. 85% of users customize their workspace. The product’s flexibility makes creation inevitable. The sharing infrastructure makes the creation visible.
This is where the creator economy angle becomes loop fuel. When you let the 1% monetize their contributions, the loop gets a fundamentally different energy:
→ Canva pays 35% royalties on marketplace template sales. 90% of templates are user-created.
→ Notion template creators sell for $20-50 each. Some make six figures annually.
→ ClickFunnels users sell their funnel templates to other ClickFunnels users. The marketplace makes the product stickier AND creates more “Powered by” artifacts.
These creators aren’t doing you a favor. They’re building businesses on your platform. Their interests and yours are perfectly aligned: they need more users to buy their templates, you need more users period. Economic alignment turns your best users into growth partners with their own incentive to promote.
Escape velocity
Every loop has a cold start, and the cold start kills more loops than anything else.
Notion seeded the template gallery with their own team’s templates. Reddit’s founders created fake accounts to make the site look active. Canva launched with professional designs before opening the marketplace. Every loop needs critical mass before it becomes self-sustaining.
The concept: escape velocity. Below a certain content or user density, the loop feels dead. Empty galleries. Sparse forums. Nobody contributes because nobody sees contributions. Above that density, the loop feels alive. Enough content to browse, enough activity to inspire creation, enough users for the network to feel real.
How to estimate it for your product:
→ Template/content platforms: how many pieces does a new visitor need to see before they feel inspired to create their own? Probably 50-100. Seed that many.
→ Community platforms: how many daily active contributors make a forum feel alive? Probably 20-30. Recruit them manually.
→ Marketplace platforms: how many listings make the catalog feel “real”? Varies, but thin catalogs with obvious gaps kill trust instantly.
Seed ruthlessly. Manufacture the initial density by hand. Then watch for the moment when organic contributions start outpacing your seeds. That’s escape velocity. That’s when you can stop pushing and start steering.
When loops break
Every loop has a decay function. Understanding it matters as much as understanding the growth.
Invite loops decay through saturation. Everyone who should be on Slack already is. The invite loop within that org is done. Growth continues only by reaching new organizations. The loop shifts from individual invites to organizational adoption, completely different motion.
Artifact loops decay through brand removal. Typeform Pro lets you remove “Powered by.” Webflow Pro removes the badge. ClickFunnels premium hides the footer. Every upgrade that removes the branding reduces the loop’s K-factor. You’re trading distribution for revenue. Sometimes that’s the right trade. But know you’re making it, and model the impact.
Identity loops decay through novelty fatigue. First year of Spotify Wrapped was magic. By year five, engagement declines. Duolingo streaks lose bragging power once everyone has one. The shareable moment needs to evolve. Spotify addresses this by changing the format annually, adding new data points, making it more personalized each year. Standing still is dying.
Loops aren’t perpetual motion machines. They require maintenance, evolution, reinvention. The companies that treat their loop as set-and-forget eventually watch it stall. The ones investing in evolution continuously, updating creation tools, adding shareable formats, deepening creator economics, sustain it for years.
Measuring your loop
Can’t improve what you can’t measure. Each loop type has specific metrics:
Invite loops: → Invite rate: what % of users invite someone? → Invite conversion: what % of invitees become active? → Time-to-invite: how quickly after signup does a user bring someone in?
Artifact loops: → Share rate: what % of users create an output a non-user sees? → Artifact-to-signup: what % of artifact viewers become users? → “Powered by” impressions: how many non-users see your brand through outputs? → Brand search lift: Typeform’s loop manifested as Google searches, not click-throughs. Track branded search volume as a loop health metric.
Identity loops: → Milestone share rate: what % of users share an achievement? → View-to-signup: what % of viewers sign up? → Moment frequency: how often does the product generate something worth sharing?
Universal: → Viral coefficient (K): invites sent × conversion rate. K > 1 = exponential. Most products land 0.1-0.5, which still meaningfully reduces CAC. → Cycle time: how long between user joining and generating next user. A product with K of 0.9 and 2-day cycle time outgrows K of 1.2 and 30-day cycle time. Speed matters as much as coefficient.
One thing most teams miss: Typeform’s insight about untrackable virality. Not all loop effects show up in attribution dashboards. If your branded search volume is climbing but you can’t trace it to specific referrals, your artifact loop might be working through brand awareness rather than measurable clicks. Track it anyway.
The bolted-on trap
Most founders don’t have a natural loop in their product. So they try adding one. Share buttons. “Invite a friend, get a free month.” Pop-ups asking users to tweet.
Almost never works. Forced virality feels like spam because it IS spam. The user does the math: “this company cares more about me spreading the product than about me using it.” That calculation, even subconscious, erodes trust.
The test: if removing the incentive kills the sharing, you don’t have a loop. You have a bribe. Real loops survive without incentives because sharing is a natural byproduct of usage.
And honestly, not every product has a distribution loop. Most don’t. That’s fine. A great product with paid acquisition is a perfectly good business. Better to build that honestly than to bolt on fake virality that annoys users and doesn’t compound.
The products that grow through their users do so because the growth is exhaust from genuine utility. Notion didn’t ask for TikToks. Typeform didn’t ask people to notice the footer. Spotify didn’t ask anyone to post their Wrapped. Users did these things because the product gave them something worth showing off, sharing, or using in a way that naturally reached non-users.
The best distribution loop is one users would run even if you didn’t have a growth team. Your job isn’t to manufacture virality. It’s to build something where usage naturally generates exposure. And then make that exposure as frictionless as possible.
