The Fourth Effect’s 2026 Summit Highlights the Rise of Startup Governance

Technology has a capital problem. Not a shortage of capital. A shortage of access to the people who decide where capital flows. That distinction matters.

The Fourth Effect’s planned 2026 annual summit in New York City, expected to mark the organization's fourth annual summit, arrives at a moment when artificial intelligence is accelerating business decisions, startup ecosystems are recalibrating power structures, and experienced operators are increasingly building portfolio careers through advisory work, board service, and angel investing. The event is being organized by The Fourth Effect, the AI-powered board marketplace founded by Breen Sullivan and Katrin de Haën. While details for the 2026 summit have not yet been publicly released, the gathering represents the latest chapter in a broader effort to connect founders, investors, executives, and advisors through structured governance relationships.

For startup founders, investors, operators, and governance leaders, the significance extends far beyond another industry event. The summit reflects a growing shift toward governance infrastructure as a competitive advantage and highlights why sophisticated operators are paying closer attention to board composition, advisory networks, and leadership ecosystems before the next market cycle fully arrives.

About The Fourth Effect

The Fourth Effect was founded in New York City in 2019 by Breen Sullivan and Katrin de Haën after identifying a persistent gap in how advisory opportunities, board seats, and investment access were distributed throughout the startup ecosystem. The company operates as an AI-powered board marketplace connecting startups with advisors, board directors, executives, and investors. Its mission centers on expanding access to leadership opportunities while helping companies build stronger governance structures.

Today, the platform spans more than 40 countries and 445 cities, bringing together more than 15,000 members, 900+ startups, 2,700+ board-ready executives, and 300+ angels, LPs, and GPs. Those numbers tell part of the story. The more interesting story is what happens when governance stops being treated as an administrative function and starts being viewed as growth infrastructure.

Why This Matters

For years, startup culture celebrated speed above all else. Raise faster. Hire faster. Scale faster. Governance often arrived later, usually after a problem surfaced. That equation is changing.

Artificial intelligence is influencing hiring decisions, risk assessment, product development, compliance workflows, and capital allocation. As technology becomes more powerful, the people overseeing those decisions become more important. AI governance is rapidly becoming a board-level issue rather than a technical issue. Directors and advisors are increasingly being asked to evaluate not only growth opportunities but also accountability, risk exposure, and long-term decision frameworks. Boards and advisory networks are no longer peripheral assets. They increasingly function as strategic operating systems, and The Fourth Effect sits directly at that intersection.

Market Context

Another force driving interest in governance infrastructure is the emergence of what many operators describe as the advisory economy. Experienced executives are no longer following a single-company career path. Many are building portfolios of advisory roles, board positions, angel investments, and fractional leadership engagements.

According to OECD workforce research, as many as 50% of professionals could participate in some form of advisory or portfolio work by 2030. That shift changes how expertise moves through the economy. Knowledge becomes more distributed. Influence becomes more networked. Relationships become more valuable than organizational charts. The Fourth Effect’s board marketplace was built around that reality long before it became a mainstream conversation.

Why New York Matters Right Now

New York continues to emerge as one of the most influential startup, venture capital, fintech, and AI ecosystems in the world. That matters because governance conversations rarely happen in isolation. They happen where capital, talent, operators, and institutions intersect.

For The Fourth Effect, New York provides a natural backdrop for discussions around board leadership, startup governance, advisory networks, and capital access. The city remains one of the few places where founders, investors, enterprise leaders, and emerging technology operators regularly collide in meaningful density. The broader ecosystem continues to be supported by organizations such as the New York City Economic Development Corporation, helping cement the city’s position as a global innovation hub.

Why The Fourth Effect Summit Stands Out

Technology conferences often compete on scale. Bigger stages. Bigger crowds. Bigger sponsorship packages. The Fourth Effect has historically taken a different approach. Previous summits have emphasized curated participation rather than mass attendance. Prior events brought together founders, investors, executives, governance leaders, legal professionals, and operators in intentionally smaller settings designed to facilitate meaningful introductions.

The result is less conference theater and more strategic interaction. That distinction matters because relationships built around governance, investment opportunities, and board leadership rarely emerge from crowded expo halls. They tend to emerge from focused conversations among people who can actually make decisions. The platform reports more than 2,000 board and investment matches facilitated across its ecosystem, highlighting the practical outcomes that can emerge from those connections.

The Operators Behind the Event

Breen Sullivan brings a background spanning legal leadership, startup operations, and executive management. Before launching The Fourth Effect, Sullivan served in senior legal and executive roles across venture-backed and high-growth technology companies.

Katrin de Haën contributes deep experience in entrepreneurship, product development, investing, and ecosystem building. Through her work as an entrepreneur and investor, she has consistently focused on expanding access to capital and opportunity. Together, they built a platform designed around a simple observation: talent is often abundant, but access is not. That observation remains remarkably relevant in today's startup environment.

What This Signals

For years, conversations centered on founders, funding rounds, and product launches. Increasingly, attention is moving toward governance, decision-making, and network infrastructure. Who advises companies. Who sits on boards. Who gains access to investors. Who influences strategy. Those questions are becoming more consequential as AI reshapes industries and startup ecosystems mature.

The Fourth Effect's planned 2026 summit is not simply a gathering. It is a signal that startup governance, board marketplaces, and advisory networks are moving closer to the center of company-building strategy. Sophisticated operators are paying attention because they understand a fundamental truth about modern technology markets: access compounds.
