FAQ
Marketplace platform questions
Common questions about launching on Poseidon—timelines, payments, models, and what ships out of the box.
How long does it take to launch a marketplace on Poseidon?
Most teams launch in months, not years. Directory and lead-routing models can go live faster; full multi-vendor checkout with seller onboarding and split payouts follows a crawl-walk-run plan scoped to your category, compliance, and payment setup.
What payment providers does Poseidon support?
Poseidon connects to Adyen, Stripe Connect, Braintree, and additional processors through an extensible payment layer—configured for split payouts, platform fees, FBO structures, and marketplace disbursements at enterprise scale.
What marketplace models does Poseidon support?
Six models on one platform blueprint: directory listings, consumer marketplaces, B2B procurement, service matching, booking and reservations, and digital goods with entitlements—so you match supply and demand the way your category actually works.
What marketplace features are included out of the box?
Auctions, request-for-quote and offer workflows, competitive bidding, vendor management, seller onboarding with KYC and catalog ingestion, and payouts with platform fees and chargeback handling—without hacking commissions in spreadsheets.
Do I have to replace my current commerce system?
No. While Poseidon is a commerce platform, it can function as a standalone marketplace vendor management, order management, and commission management system.
Is Poseidon headless?
Yes. Poseidon is API-first and event-driven—compose your own frontends, prompt custom operator dashboards when you need them, and embed marketplace rails into your existing identity, data, and tooling without another monolithic admin UI.
What is Poseidon?
Poseidon is Trident’s marketplace platform—AI-native infrastructure at the intersection of commerce, fintech, and logistics. It powers discovery, negotiation, onboarding, checkout, and payouts for multi-sided marketplaces.
