1. Ask Clarifying Questions
Before jumping into ideation, I’d clarify the scope and constraints.
Are we focusing on individuals hosting personal events (birthdays, house parties) or corporate event organizers?
Lets focus on personal events.
Is this for in-person gatherings, virtual events, or hybrid experiences?
Lets focus on in-person gatherings.
Are we focusing on small casual gatherings (10–50 guests) or large-scale events (100+ people)?
Its upto you to decide.
Should we handle only planning or also execution (bookings, vendors, payments)?
Its upto you to decide.
Is this a consumer platform (self-service) or marketplace connecting hosts to vendors?
Its upto you to decide.
Is the goal monetization (commissions, subscriptions) or engagement (community growth)?
Its upto you to decide.
2. Define the Goal
It’s mission is to make hosting social gatherings effortless by providing an all-in-one digital platform that helps users plan, organize, and enjoy parties seamlessly.
The key metric determining the success of this mission at the adoption phase post launch is user engagement, measured by the number of events created per user, RSVP participation rate, and repeat event creation. Higher engagement reflects stronger trust and adoption among hosts and guests.
This product competes with tools like Evite, Eventbrite, and WhatsApp, but differentiates itself through its integrated experience — combining planning, vendor discovery, and budgeting in one place.
Greater engagement creates a flywheel effect: more events attract more guests, who become future hosts, drawing in more vendors and driving sustained platform growth and revenue.
3. Define User Segments
Following are the list of user segments,
Casual Hosts: Individuals planning small gatherings (birthdays, dinners, house parties).
Frequent Event Planners: People who host or organize events regularly (community organizers, influencers).
Corporate Event Managers: Teams arranging office events or offsites.
Vendors/Service Providers: Caterers, DJs, decorators looking for business visibility.
Focus Segment for MVP in Adoption phase:
Casual Hosts (Individuals 25–40 years old) — They plan 3–5 events per year but find coordination (guests, food, vendors) stressful. They rely on WhatsApp, Google Sheets, and mental notes today — a fragmented and inefficient workflow.
4. List and Prioritize Pain Points
Following are the list of pain points for the Casual Hosts:
Hosts often struggle with guest coordination, as managing RSVPs, last-minute cancellations, and dietary preferences is largely manual and confusing.
Finding reliable vendors such as caterers, DJs, or decorators within a set budget is equally challenging and time-consuming.
There is also a lack of a simple way to track expenses or split costs among co-hosts, making budget management cumbersome.
Hosts face communication overload due to endless WhatsApp threads for updates, invites, and logistics.
Post-event memories like photos and videos are scattered across chats and drives, making it difficult to relive or share the experience in one place.
Top 3 Pain Points to Solve First:
Guest coordination, Vendor discovery, and Communication overload.
