Marketplace startups face a problem that single-sided products often do not: a user can finish onboarding and still find no suitable person, provider or opportunity on the other side. Registration numbers may grow while the marketplace delivers little practical value.
Effective marketplace engagement starts with supply quality, accurate availability, user preferences and the actions that indicate a real connection. Marketing messages help when they bring somebody closer to a relevant match, booking or application—not when they substitute noise for missing supply.
What makes marketplace engagement different?
A marketplace serves at least two groups whose needs must align. Examples include workers and employers, service providers and customers, or independent professionals and organizations. Each side has a different activation journey.
For a provider, useful activation may mean completing a trustworthy profile and receiving a qualified inquiry. For a customer, it may be receiving an appropriate response or successfully arranging a booking. Those events should be tracked separately.
An empty search result is a product and supply problem before it is a messaging problem. Repeatedly urging a user to return does not create a good match if the underlying marketplace has no relevant options.
Build minimum useful supply before inviting demand
Identify the first city, segment or category where your team can reliably deliver useful results. A startup serving every location with thin supply may disappoint more users than one providing a strong experience in a smaller area.
Define what a complete provider listing requires: current availability, an accurate offering, clear service area and trustworthy contact or booking instructions. Keep data refreshed and remove stale opportunities.
If a user cannot find a result, offer an honest waitlist, an alert for a future matching opportunity or a narrower alternative. Do not fabricate activity or pretend a provider has agreed to respond.
Use intent and behavior to guide the next step
Ask for only the preferences needed to discover something meaningful: location at a suitable privacy level, category, timing or intended outcome. Explain why each is useful and allow people to adjust it.
Trigger communications from genuine events. A saved search can notify a user when a relevant opportunity appears. A provider might receive an inquiry that fits their declared availability. After a completed match, request feedback about the experience.
Suppress notifications after an opportunity closes, a request is fulfilled or the user opts out. A notification should never disclose sensitive contact details or precise location without appropriate permission.
Published Braze case studies: Hosco and Hamperapp
Braze reports that Hosco, a hospitality recruitment platform, used action-aware onboarding and re-engagement to encourage completed profiles, relevant job applications and continued activity. The lesson for a startup marketplace is to treat meaningful interactions as the goal, rather than sending the same encouragement to everybody.
Braze also describes how Hamperapp, an on-demand services business, needed to move customers from registration to their first order and then develop repeat activity. Its published case focuses on lifecycle messaging across channels as the service expanded.

Design a match-to-outcome workflow
A simple journey can have four steps: request created, relevant options available, connection initiated, and outcome confirmed. Each event should be supported by real product data and a clear owner for unresolved issues.
When a user asks about a provider, make contact expectations transparent. Do not say 'confirmed' when the request is merely submitted. If a booking expires or a match fails, give a clear next step.
An AI assistant can help explain listing details and accepted procedures when grounded in approved records. It should not invent a provider's availability, suitability or response.
Metrics that matter for a two-sided startup
Track qualified supply per active segment, search-result usefulness, time to first relevant option, inquiry acceptance, completed bookings or applications, and repeat successful interactions. Monitor negative signals like unmatched requests and stale listings.
Separate marketplace liquidity metrics from messaging engagement. A strong email open rate cannot compensate for a poor completion rate. Likewise, a reminder may generate a visit without delivering a match.
Use holdouts or phased tests where practical to estimate the incremental effect of notifications. Above all, review marketplace operations and relevance—not just campaign statistics.
Two-sided marketplace activation: measure real liquidity
Quick answer: Marketplace engagement is successful when two sides find a useful match and progress toward a completed transaction, booking or collaboration. Total signups alone can hide an empty marketplace.
- Define the useful supply available by category, location and time before attracting more demand.
- For each new buyer or requester, show relevant available options and explain missing supply honestly.
- Track intent-to-match, match-to-contact, contact-to-outcome and the median time between each stage.
- Notify providers and requesters only about genuinely relevant opportunities and stop alerts after a match closes.
Practical example and measurement template
Illustrative example, not a Scarvion customer result: Illustrative example: a service marketplace might count a completed, mutually confirmed booking as its first-value event. A message introducing a provider who is unavailable does not count as successful activation.
What to measure: Track active supply, active demand, eligible matches, response latency, confirmed outcomes, repeat use and unmatched requests. Report these by local market because aggregate growth can conceal poor liquidity in individual cities.

Frequently asked questions
What is marketplace startup activation?
It is the first meaningful marketplace outcome, such as a qualified inquiry, accepted connection, booking or application, rather than a completed signup alone.
How should a marketplace notify users about opportunities?
Send relevant, permission-based notifications tied to verified availability, declared interests and meaningful events, with clear suppression when opportunities close.
Can automation solve a marketplace supply problem?
No. Automation can make existing opportunities easier to discover, but it cannot replace reliable supply, truthful listings and responsive participants.
