Software Development Brooklyn, New York 201–500 employees Founded 2017 Privately Held

Fundraise Up operates a donation platform for nonprofits, built on Node.js + React + TypeScript + Kafka + ClickHouse, with Stripe and PayPal payment rails and Salesforce/HubSpot for donor management. The company is scaling aggressively—accelerating hiring across product and engineering with a heavy leadership focus (34 leads, 2 VPs)—while adopting NetSuite and moving off QuickBooks. Active pain points (page load times, conversion optimization, global payment support, tech debt) and project list (A/B testing infrastructure, data marts, dynamic widgets) reveal a company transitioning from feature-driven toward optimization and platform maturity.
