Problem

Your Marketplace Has Traffic. It Doesn’t Have Retention.

Marketplaces live and die on liquidity. But most are haemorrhaging value after acquisition:

New users sign up but never complete their first transaction your activation flow isn’t doing enough

Supply-side engagement drops off after onboarding, and you have no lifecycle strategy to keep sellers, hosts, or providers active

Demand-side users transact once and disappear there’s no post-transaction journey to drive repeat behaviour

Your lifecycle campaigns treat both sides of the marketplace the same, ignoring fundamentally different motivations and triggers

Transaction data, user behaviour, and engagement signals sit in silos so personalisation is impossible at scale

  • Do you build separate lifecycle strategies for supply and demand sides?

    Yes. Marketplace retention requires distinct strategies for each side. We design separate journey maps, segmentation models, and campaign flows for buyers and sellers (or guests and hosts, passengers and drivers, etc.) each optimized for the behaviours and motivations unique to that side.

  • What marketplace models have you worked with?

    We’ve worked with booking platforms, job placement marketplaces, ecommerce marketplaces, and service platforms. Whether your marketplace is B2C, B2B, or peer-to-peer, we design lifecycle strategies that drive activation and repeat transactions on both sides.

  • How do you handle the complexity of marketplace user journeys?

    We map every journey stage for both sides from sign-up to first transaction to repeat engagement then architect the event tracking, segmentation, and automation logic to trigger the right message at the right moment. AI helps us identify drop-off points and revenue gaps that manual analysis misses.

  • Can you help with payment drop-off and transaction completion?

    Absolutely. We build behaviour-triggered flows that recover abandoned transactions — payment reminders, progress nudges, and incentive-based re-engagement personalised by user stage and transaction type. This is often one of the fastest revenue wins for marketplace clients.

  • What platforms do you work with for marketplace lifecycle?

    We’re platform-agnostic Braze, Customer.io, MoEngage, CleverTap, Klaviyo, and more. We choose the stack that fits your marketplace’s complexity, volume, and cross-channel requirements.

  • How quickly can we see results?

    Most marketplace brands see measurable improvements within 30–90 days. Activation flows, transaction recovery sequences, and re-engagement campaigns deliver quick wins. Our 30-day money-back guarantee means you can judge the impact risk-free.
