What is Siren?

What does Siren do?

Siren is an incentive program builder. It runs as a WordPress plugin, or as Siren Cloud, hosted for you. Most people find it while searching for an affiliate plugin, but Siren handles far more than traditional affiliate programs. You define the rules for how people earn rewards, and Siren tracks the activity, calculates what’s owed, and manages payouts. On Plus and Pro, Siren can also send payouts for you through Stripe or PayPal.

What kinds of programs can you build?

Most people come to Siren for a standard affiliate program: pay a commission when a partner drives a sale. That’s the most common shape, and Siren does it well. But the same engine handles a lot more. Course platforms use Siren to pay instructors a share of the revenue their courses generate. Marketplaces like Etsy-style art and print-on-demand sites pay vendors royalties whenever their products sell. SaaS companies run partner programs that pay recurring commissions to resellers and integration partners. And plenty of businesses use Siren internally, running sales team SPIFs and per-sale bonuses for their own employees.

The common thread is pay for performance, not hours.

Siren can also pay people in ways a plain affiliate plugin can’t. On Essentials and up, you can pay rewards in store credit or points that collaborators spend at your WooCommerce, Easy Digital Downloads, or LifterLMS checkout, and give products owners who earn when they sell. On Plus and Pro, you can link a customer to a collaborator for life, so the collaborator earns on that customer’s later purchases with no new click or coupon. Whatever you build, you can start from a recipe instead of a blank program.

How does Siren track and pay collaborators?

Siren is built around a handful of core concepts that connect to form a complete incentive system: programs, collaborators, engagements, conversions, obligations, and distributors. For a full walkthrough of how they fit together, see the User Guide concepts.

How are reward amounts calculated?

Siren supports percentage-based, fixed-per-transaction, and fixed-per-product rewards, and the right choice depends on what you’re incentivizing. See Choosing an Incentive Structure for help picking one.

Which plugins does Siren work with?

Siren works with WooCommerce, Easy Digital Downloads, NorthCommerce, LifterLMS, LearnDash, Gravity Forms, and Ninja Forms. Each integration plugs the same core system into a different commerce or engagement platform, so your programs behave consistently regardless of which plugin runs the storefront. See the integration feature matrix for what each integration supports. Siren Cloud records sales from Stripe, Shopify, or a WordPress site connected through the Siren Cloud Connector.
