Design effective referral programs and viral loops that drive sustainable growth.
Creates isolated Git worktrees for feature branches with prioritized directory selection, gitignore safety checks, auto project setup for Node/Python/Rust/Go, and baseline verification.
Executes implementation plans in current session by dispatching fresh subagents per independent task, with two-stage reviews: spec compliance then code quality.
Dispatches parallel agents to independently tackle 2+ tasks like separate test failures or subsystems without shared state or dependencies.
Design effective referral programs and viral loops that drive sustainable growth.
Only the referrer gets rewarded.
Best for:
Examples:
Template:
Refer a friend and get [reward].
Share your unique link: [referral_url]
Both referrer and referred user get rewarded.
Best for:
Examples:
Template:
Give [friend_reward], get [referrer_reward].
Share your link and you both win: [referral_url]
Rewards increase with number of successful referrals.
Example tier structure:
| Referrals | Reward |
|---|---|
| 1 | Free month |
| 3 | Exclusive feature unlock |
| 5 | Premium plan for 3 months |
| 10 | Lifetime premium access |
| 25 | Cash payout or swag box |

The viral coefficient (K-factor) determines whether your referral loop is self-sustaining.
K = i * c
Where:
i = number of invites sent per user
c = conversion rate of each invite
If K > 1: viral growth (each user brings more than one new user)
If K < 1: referrals supplement but don't replace other acquisition
Users send an average of 5 invites (i = 5)
15% of invites convert to signups (c = 0.15)
K = 5 * 0.15 = 0.75
With 1,000 initial users:
- Cycle 1: 1,000 * 0.75 = 750 new users
- Cycle 2: 750 * 0.75 = 563 new users
- Cycle 3: 563 * 0.75 = 422 new users
- Total after 10 cycles: ~3,570 additional users from referrals
The speed of the viral loop matters as much as K:
Effective growth = K / cycle_time
A K of 0.5 with a 1-day cycle > K of 0.8 with a 30-day cycle
| Lever | Action |
|---|---|
| Increase invites (i) | Make sharing frictionless, prompt at key moments |
| Increase conversion (c) | Better landing page, stronger incentive, social proof |
| Reduce cycle time | Instant reward delivery, real-time notifications |
Pros: High conversion, personal, trackable Cons: Lower volume, requires email access
Template:
Subject: I thought you'd like [Product] -- here's [reward] to try it
Hey [Name],
I've been using [Product] for [time] and it's been great for [specific benefit].
I wanted to share my referral link so you can get [friend_reward]:
[referral_url]
[Your name]
Pros: High reach, low effort, viral potential Cons: Lower conversion rate, less personal
Platform-specific templates:
Twitter/X:
I just [achievement/milestone] with @Product! If you want to try it,
use my link and we both get [reward]: [referral_url]
LinkedIn:
I've been using [Product] to [professional benefit] and the results
have been impressive: [specific metric].
If you're looking for [solution], here's my referral link
(we both get [reward]): [referral_url]
WhatsApp/SMS:
Hey! I've been using [Product] and really like it. They have a
referral deal -- we both get [reward] if you sign up through my link:
