The Fourth Effect is the platform for the advisory economy. Half of all professionals will work across multiple companies by 2030 — as advisors, board members, and fractional executives. It's already happening, and there's no system for any of it. We built it. For startups, it's how you find the right people, structure the relationship properly, and manage your advisory bench over time. For professionals, it's how you build a portfolio career with real structure, real equity, and a reputation that compounds. Powered by a global community of 20,000+ founders, executives, advisors, board directors, and investors across 60+ countries. New platform launches late June 2026.
