Your expertise is an asset.
Treat it like one.
The Fourth Effect is where experienced professionals build portfolio careers on their own terms. Discover advisory opportunities, formalize your engagements, track your equity, and manage every relationship in one place.
Launching Summer 2026
The advisory economy is here. Are you in it?
The OECD estimates that by 2030, half of all professionals will participate in some form of advisory or portfolio work. Executives, operators, investors, and domain experts are increasingly lending their expertise to multiple companies, not just one.
But right now, the experience of being an advisor is fragmented. Opportunities come through personal networks. Terms are negotiated ad hoc. Equity is promised but rarely tracked. There is no single place to manage your advisory career.
Until now.
What The Fourth Effect Does
DISCOVER
Get matched with startups looking for exactly what you bring. Our matching engine goes beyond titles and keywords to connect you with companies at the right stage, in the right sector, with the right needs.
FORMALIZE
Every engagement is backed by a proper agreement with clear terms: your role, your compensation, your vesting schedule, your IP protections. Whether you are starting a new relationship or cleaning up an existing one that has been running on a handshake.
MANAGE
Track all your advisory engagements, equity positions, milestones, and renewals in one place. See your full portfolio career at a glance, not scattered across email threads and spreadsheets.
Already Advising?
Let's get it in writing.
If you are already advising startups without a formal agreement, you are not alone. Most advisory relationships start informally and stay that way. But that means no clarity on equity, no IP protection, and no written record of the value you are providing.
The Fourth Effect lets you initiate the cleanup from your side. Bring your existing engagements onto the platform, define the terms, and get everything formalized without waiting for the founder to take the first step.
The new platform launches this summer.
