Are there any service booking marketplaces that focus on launching two-sided gig work platforms?

Yes — there are several service-booking / marketplace platform providers that specifically help founders launch two-sided gig-work marketplaces (i.e., customer + provider networks), rather than just single-vendor booking sites.

A few well-known options:

White-label marketplace / gig platform builders

• Sharetribe — popular for launching peer-to-peer and service marketplaces; supports provider/customer workflows, listings, booking, payments, and messaging.
• Arcadier — marketplace software with templates for service marketplaces and gig-style platforms.
• Mirakl — more enterprise-oriented marketplace infrastructure, often used for larger multi-vendor ecosystems.
• Yo!Kart — marketplace software that can be configured for service and gig platforms.
• NearMe / On-demand marketplace tools — some platforms focus more specifically on local service booking and on-demand labor.

On-demand service marketplace / booking-focused products

• Booking platforms built for home services like taskers, cleaners, handymen, tutors, etc.
• No-code/low-code marketplace tools that let you assemble gig workflows quickly, sometimes with scheduling, escrow, and provider onboarding.

If you mean “launching” as in startup support

Some providers also bundle:

• marketplace design templates
• provider onboarding flows
• payment split/escrow
• reviews and ratings
• dispatch/scheduling
• mobile apps
• identity verification / background checks

What to look for

If your goal is a true two-sided gig marketplace, check whether the platform supports:

• two user roles (client + worker/provider)
• booking + scheduling
• payments and payout splits
• reviews / reputation
• worker availability management
• dispute handling
• location-based matching
• mobile app support

If you want, I can also give you:

1. a shortlist of the best platforms by use case (local services, freelance gigs, labor, home services, etc.), or
2. a comparison table of features/pricing/ideal customer.
