Verticalized Expert Network
Build a niche expert network focused on a single industry vertical (e.g., marketing, real estate, automotive, AI) to compete against generalist platforms like GLG and AlphaSights.

GLG, AlphaSights, and similar expert network platforms are massive businesses (some with 9-figure EBITDA) that connect investors and consultants with subject matter experts across all industries. The speaker argues these generalist platforms are ripe for vertical disruption — a focused network that only serves one domain (e.g., marketing, healthcare, real estate, automotive, AI) can credibly out-compete generalists in that niche by having deeper, more curated expert rosters and domain-specific credibility.
The speaker's own company, Ox Insights, is a real-world example of this thesis — a marketing-specific research firm serving private equity. Additional monetization can come from recording and transcribing expert calls, then making them searchable in a proprietary database after a 90-day delay (a model used by a company called Tusk that was later acquired). Vertical differentiation also creates a natural sales pitch: 'We only do marketing, so we're better at marketing experts than the generalists.'

03 THE VERDICT
Tegus proved the transcript database model works and sold for a significant multiple. GLG and AlphaSights have demonstrated nine-figure EBITDA is achievable. The vertical niche angle is underexplored and creates a clear, defensible positioning. The biggest challenge is bootstrapping both sides of the marketplace simultaneously, but starting with a single tight vertical and a warm network makes this highly executable for the right founder.
