Local Experience Marketplace for City Insiders & Travelers

Problem and target customer

Why this exists

Customer problem

Locals offering unique city experiences and travelers seeking them rely on scattered tools, manual messaging, and spreadsheets to coordinate bookings, payments, and scheduling—creating friction on both sides of the transaction.

Who pays

Independent local hosts and small experience operators who need a listing-and-booking channel without building custom software, plus travelers looking for authentic city activities.

Business model

Two-sided marketplace connecting local hosts with travelers through curated experience listings and instant booking.

Editorial note

This marketplace narrows the scope to one transaction: a local host lists a city experience with bookable time slots, and a traveler discovers, pays for, and confirms that experience. The MVP deliberately excludes reviews, in-app messaging, and AI-generated content to ship the booking loop first.

The visual identity follows a warm coral and off-white palette with oversized typography and asymmetric card layouts featuring city photography placeholders, giving each listing an editorial feel that distinguishes it from generic listing platforms.

Product goal

Who it serves and what it must change

Target user: Local hosts listing city experiences and travelers booking those experiences
Problem: Booking a local city experience requires manual coordination across messaging, spreadsheets, and separate payment tools with no shared source of truth for availability.
Measurable outcome: A guest can search, book, pay for, and receive confirmation on a local experience in under five minutes, and the host sees the booking on their dashboard automatically.

Core entity outline

Entities and business rules

Experience

A local host's listing describing a city activity

Fields: title, description, city, meeting_location, price_per_person, capacity, host_id, status
Relations: belongs to Host, has many TimeSlots, has many Bookings

TimeSlot

A bookable window for an experience with a specific date, start time, and capacity

Fields: experience_id, start_datetime, end_datetime, max_capacity, booked_capacity, status
Relations: belongs to Experience, has many Bookings

Booking

A guest's reservation for a specific time slot with payment and party size

Fields: time_slot_id, guest_id, party_size, total_price, payment_status, status, created_at
Relations: belongs to TimeSlot, belongs to Guest

Host

A local user who creates and manages experience listings

Fields: name, email, bio, payout_account_id, subscription_status
Relations: has many Experiences

Guest

A traveler who searches and books experiences

Fields: name, email, payment_method_id
Relations: has many Bookings

Business rules

A time slot cannot accept bookings when booked_capacity equals max_capacity
Booking total_price equals price_per_person multiplied by party_size
A booking cannot be created for a past time slot
Cancelling a confirmed booking increments the time slot's available capacity back
Only the experience's host or the booking's guest can cancel a booking

Architecture and data flow

Components, integrations, and controls

Marketplace API

Handles listing CRUD, search queries, booking creation, and availability updates

Payment Service

Processes guest checkout, holds funds, and issues payouts to hosts and refunds for cancellations

Notification Service

Sends booking confirmation and cancellation emails to host and guest

Calendar Sync

Creates calendar events for confirmed bookings on host and guest calendars

Integrations

Stripe for payment processing, payouts, and refunds
Transactional email provider for booking notifications
Calendar API for syncing confirmed bookings to host and guest calendars
Google Maps API for rendering meeting point locations

Data flow

Guest selects a time slot and submits booking → API creates a pending Booking and calls Stripe for payment
Stripe confirms payment → API updates Booking to confirmed, decrements TimeSlot capacity, and fires a webhook to Make
Make receives webhook → sends confirmation emails and creates calendar events for both parties
Cancellation request → API updates Booking to cancelled, issues Stripe refund, increments TimeSlot capacity, and fires cancellation webhook

Failure handling

If payment fails, the booking remains in pending state and the time slot capacity is not decremented
If the email service is unavailable, the booking is still confirmed and a retry queue resends the notification
If the calendar sync fails, the booking confirmation proceeds and the calendar event is retried asynchronously

Security

Payment tokens never touch the database; Stripe handles card data via client-side SDK
Host payout account IDs are stored securely and never exposed to guests
API endpoints require authentication for dashboard and booking management actions

Rate limits

Search API limited to 60 requests per minute per IP to prevent scraping
Booking creation limited to 5 per minute per guest to prevent slot hoarding

Deliverables and acceptance

Definition of done for the MVP

Deliverables

Deployed marketplace web app with discovery, detail, checkout, and dual dashboard screens
Relational database with Experience, TimeSlot, Booking, Host, and Guest tables
Stripe integration for checkout, payouts, and refunds
Make scenario for email notifications and calendar sync on booking events
Host and guest dashboards reflecting real-time booking status

Acceptance criteria

A host can create an experience with all required fields and publish at least one time slot that appears in guest search results
A guest can search experiences by city and date and see only slots with available capacity
Completing checkout processes payment via Stripe, confirms the booking, and sends email to both host and guest within two minutes
Host and guest dashboards display the booking with correct status and party size matching the checkout submission
Cancelling a confirmed booking issues a refund through Stripe and restores the time slot's available capacity

Recommended stack

Enough technology for the first version

Frontend

Lovable

Rapid build of the coral-and-off-white marketplace UI with search, listing detail, and dual dashboard screens.

Backend and database

Railway

Hosts the relational database for experiences, bookings, and slots plus the API layer for payment and email webhooks.

Automation glue

Make

Bounded integration for sending confirmation emails and syncing calendar events after a booking webhook fires.

Payments

Stripe

Handles guest checkout, host payouts, and refund flows for cancelled bookings.

Maps

Google Maps API

Renders meeting point locations on experience detail pages and search results.

Why this is sufficient

Lovable builds the visual marketplace front-end quickly with the specified warm editorial design. Railway provides durable storage for listings, slots, and bookings with a reliable API for payment webhooks. Make handles the bounded glue of email dispatch and calendar sync without becoming core logic. Stripe and Google Maps are proven external dependencies the source explicitly requires.
