Referral Loop

The best channel is users inviting users — especially for connection products where value grows with network size. Referral fails when the invite is spammy or the incentive feels like a pyramid scheme.

Chains from [[growth-strategy]] (ICP, north-star metric) and [[community-engagement]] (engaged users refer more). Complements [[email-nurture]] (referral prompts in sequences) and [[social-distribution]] (share assets).

Use referral-loop checklist alongside this process.

When to Use

• Network/product value increases with more users (developer-connection, communities)
• NPS or satisfaction high but organic invites low
• Launching invite-only or waitlist with referral priority
• Adding "invite a friend" to activation flow

Skip when: product isn't shareable, no clear invite moment, or core experience broken (fix product first).

Process

1. Find the natural invite moment

Best triggers — user just got value:

Never ask on sign-up screen before first value.

2. Design the loop

User gets value → Prompt to share → Easy share mechanism → Friend lands → Friend activates

              (reward optional)

Components:

• Share link — unique referral URL per user (?ref=username)
• Share copy — pre-written message user can edit (X, LinkedIn, email, copy link)
• Landing — friend sees referrer context ("Alex invited you")
• Tracking — attribute sign-up to referrer
• Reward (optional) — both sides benefit; keep ethical and simple

3. Incentive design (developer products)

Prefer access and status over cash for dev audiences.

4. Anti-abuse

• Cap rewards per month
• Require referred user to activate (not just sign up) before reward
• Block self-referrals and disposable emails
• Manual review if spike detected

5. Launch and measure

K > 0.15 is meaningful for early products; K > 1.0 is exceptional.

6. Promote the loop

• In-app prompt at invite moment
• Email Day 7 in [[email-nurture]] sequence
• Community showcase of top referrers ([[community-engagement]])
• Social template for [[social-distribution]]

Common Rationalizations

• "Referral widget on homepage is enough" — Homepage visitors haven't experienced value yet.
• "Cash will make it viral" — Attracts fraud; devs prefer access/status.
• "No reward needed" — Small mutual benefit increases share rate 2x without feeling salesy.

Red Flags

• Ask to refer before first success
• Referral link broken or not tracked
• Reward on sign-up only — bots inflate numbers
• No referrer context on friend's landing page
• Pyramid-style multi-level rewards

Verification

• Invite moment identified (post-value, not pre-value)
• Share link, copy, landing page, tracking designed
• Incentive chosen with abuse caps
• Activation required before reward pays out
• Metrics dashboard or spreadsheet template ready
• In-app + email promotion planned
