The Challenge

The Problem We're Solving

Despite growing social awareness among youth, a significant disconnect exists between the desire to volunteer and the ability to take meaningful action.

60%

Hard to Find Events

Students struggle to find volunteer opportunities aligned with their interests, location, and schedule.

55%

Scattered Information

Event info is fragmented across Instagram, WhatsApp groups, notice boards — no single source of truth.

35%

Lack of Trust

Users distrust authenticity of events found through informal social media channels.

95%

Missed Opportunities

Nearly all respondents reported missing at least one volunteer opportunity due to insufficient information.

💡
The Gap: 80%+ of students use Instagram & WhatsApp for event discovery — but these channels lack filtering, event management, progress tracking, and recognition systems. Dedicated platforms like Unstop aren't localised for Indian university students.

What Sets Us Apart

Our Unique Edge

01

Evidence-Driven Design

Every feature was validated through primary research (20-person survey) and 7 academic papers. Not assumptions — data.

02

Indian University Context

Unlike Unstop or VolunteerMatch, Impactly is built specifically for Indian college students — Hindi support, local categories, and campus-centric events.

03

Complete Ecosystem

Not just event listing — a full social-impact ecosystem with feed, messaging, friendships, gamification, and leaderboard in one app.

04

Real-Time Architecture

Built on Supabase Realtime subscriptions — live notifications, instant messaging, and reactive state updates without polling.

05

Row-Level Security

Every database table has RLS policies. Users can only access their own data. Privacy isn't an afterthought — it's structural.

06

Cross-Platform, Single Codebase

One Flutter codebase runs on Android, iOS, Web, and Windows — consistent premium experience everywhere.
