Expert network market hits USD 3B in 2025, fragmentation accelerates

The global expert network industry reached roughly USD 3 billion in 2025, according to Inex One CEO Max Friberg's annual market overview published in early February. The headline number matters less than what sits underneath it: the industry has refused to consolidate, the legacy operators are losing margin, and a fourth generation of regional and sector specialists keeps showing up.

That last point is the one to sit with. The consensus call five years ago was that GLG, Guidepoint, Third Bridge, and AlphaSense (post-Tegus) would absorb the long tail. They haven't.

What the source reports

Friberg's framing splits the industry into four generations of players, with regional leaders carving out share from the legacy operators. The two pressures he identifies on the incumbents are specific:

First, expert fatigue. Lower barriers to entry mean more networks chasing the same expert pool with the same questions. Experts get pinged repeatedly on near-identical requests; clients get pitched near-identical rosters. Margin erodes on both sides of the marketplace.

Second, marketplace efficiency. Platforms that aggregate networks (Inex One among them) let clients route requests to whichever provider performs best on a given vertical. That structurally rewards specialists and punishes the volume-driven generalist model that built the industry.

The combination, per the Inex One write-up, is an industry that's more fragmented in 2025 than it was in 2020, with new firms launching every year around specific regions or sectors.

How to read the USD 3B figure

Market sizing for expert networks is unaudited and varies by what's counted. The number includes call revenue, transcript and library products, and increasingly survey and custom-research lines for the larger players. It does not have a regulatory backstop the way audit fees or asset-management AUM do. Take the USD 3 billion as a directionally useful Inex One estimate rather than a SEC-filed disclosure.

The more durable signal is the structural claim: fragmentation, not consolidation. That's testable against observable behavior, new entrants by year, regional network launches, vertical-specialist funding rounds, and the read holds.

Caveat on the source

Inex One operates a marketplace that benefits commercially when buyers route through aggregators rather than directly to incumbents. That doesn't make the analysis wrong, the fragmentation thesis is observable independently, but readers should weight the framing accordingly. The most useful pieces of the post are the structural observations on expert fatigue and marketplace efficiency. The most self-interested piece is the closing pitch on infrastructure for the next phase.

Treat this the way you'd treat a sell-side note from a broker with skin in the game: read the data, discount the conclusion by the author's position, and form your own view.

What to ask next

For anyone covering or selling into this space, the questions Friberg's piece surfaces but doesn't fully answer:

• What share of total industry call volume now flows through marketplace platforms versus direct-to-network procurement?
• Which sector or regional specialists are growing fastest, and at what margin profile relative to the generalists?
• How are the top-five networks responding on pricing, are they discounting to defend volume, or holding price and accepting share loss?
• Where does AI-assisted expert discovery end and human-curated network value begin in 2026?

Those are the questions a research analyst should put to operators on both sides of the table over the next two quarters.
