Launch a contest.
Keep the audience.

Giveaways get attention. ContestOS turns that attention into contacts, referrals and repeat customers — with the drawing done fairly and on the record.

Free to build. You only pay when you publish.

The whole campaign, not just the entry form

Create

A guided wizard sets the prize, dates, eligibility and entry form with smart defaults.

Capture

Entrants become contacts with separate email and SMS consent, recorded and auditable.

Multiply

Every entrant gets a referral link. Verified referrals earn bonus entries automatically.

Draw

Freeze the pool, pick the winner server-side, then reveal it with a celebration.

Every contest leaves you with an asset: the contacts.

Contacts and entries stay separate, consent is tracked per channel, and non-winners become your next campaign.
