Replaced delayed CSV workflows with realtime fundraiser + donation visibility

This case covers a web application that moved fundraiser operations from delayed, donation-only CSV snapshots to realtime creation and donation signals integrated with Meta APIs.

Challenge

  • Prior workflow depended on manually downloaded CSV files that were at least 48 hours delayed.
  • Teams could only see fundraisers after donations appeared, missing newly created but not-yet-donated pages.
  • The lag degraded outreach speed and reduced the ability to guide fundraisers effectively.

Implementation

  • Built an Express + Svelte + MongoDB app for event participants to create fundraisers in one click.
  • Integrated Meta APIs so fundraiser creation events were captured at source instead of inferred later.
  • Surfaced donation activity in realtime, enabling chat and success teams to operate with current context.

Outcomes

  • Eliminated 48-hour baseline delay in fundraiser discovery and donation context.
  • Enabled operations across millions of users and tens of millions of donation data points.
  • Improved decision quality across sales, customer success, and analytics functions.
