The spread engine

Six mechanisms. One unstoppable loop.

Virality is a system, not a feature. Remove any one piece and momentum stalls. Audit each mechanism to see where the loop needs work now.

Hook

Win the first few seconds

Create a curiosity gap or immediate payoff before anyone has committed to learning the product.

Wordle — one puzzle, one minute, done.

Loop

Make use create distribution

Put sharing inside the core action, so each successful use introduces the product to someone new.

Calendly — every invite link markets the tool.

Incentive

Give both sides a reason

Replace vague goodwill with a mutual reward for the person sharing and the person joining.

Dropbox — free storage for both sides.

Low friction

Reduce ten taps to one

Remove walls, copying, and explanations that quietly destroy referral follow-through.

Venmo — a payment request needs zero explanation.

Trigger

Create the return cue

Use a recurring need, habit, or timely notification before the loop loses momentum.

Duolingo — the streak notification, daily.

Network effect

Turn growth into a moat

Design the product so every new participant improves the experience for everyone already there.

TikTok — more creators and viewers sharpen discovery.

Your decision system

Move from instinct to a sharper next experiment.

Each Growth Orbit playbook gives you a clear assessment, practical prompts, and a focused way to redesign the part of your loop that needs attention.
