The history of Third Bridge
When Third Bridge started out, GLG was dependent on its traditional static network. Experts were recruited proactively, at fairs and from telephone directories. Onboarding an expert was time-consuming and complex. Third Bridge, lacking a database of experts, began recruiting experts directly for live projects. To enable this, they sped up the onboarding of experts with modern tech tools and user-friendly interfaces. This business model’s success was supported by the even faster growth of LinkedIn.
Third Bridge business areas
The company combines a large database with custom recruiting, promoted in two business areas:
Expert calls (formerly branded as Connections), a standard expert network operation with phone calls, surveys, project recruiting, etc. This is the core service offered by Third Bridge, with approximately half of the firm’s staff working in the Connections research team.
Library (formerly branded as Forum), a three-part product, which includes company databases, a transcript library (including hosted expert calls, which were the core feature of Forum previously), and the ability to AI search all this content.
Their product, Library (formerly Forum), has seen rapid growth since it was created in 2015. As of June 2020, approximately 10% of Third Bridge’s employees were working on generating content for the Forum, conducting and transcribing 5000+ expert interviews per year. Clients pay per-seat subscriptions to access Third Bridge’s growing database of call transcripts, which by 2026 covered more than 65,000 companies. Our expert sources mention that it represents ~25% of Third Bridge’s revenues, and the lion’s share of its net profit. In October 2022, Third Bridge started hiring for roles to produce user-generated content. Just like Tegus, Third Bridge will transcribe expert calls done by its users, and post them to its library for others to read. To date, all transcripts have been produced by full-time Third Bridge employees interviewing experts.

Third Bridge partnerships
As many expert networks venture into content, there are two approaches: wide distribution and a walled garden. Third Bridge Library (formerly known as Forum) started as a "walled garden": clients needed a subscription to access the content.
Third Bridge eventually pivoted and optimized for distribution. Today, Third Bridge publishes its content both on Forum and on several "distribution partners", starting with Bloomberg (year unknown).

From 2025, they expanded distribution to multiple other 3rd-party platforms:
June 2025 - Joined a consortium investing in Aiera, where Third Bridge's content will be presented alongside others.
July 2025 - Publishing its content on Portrait Analytics and Hebbia.
Sep 2025 - Added content distribution on Model ML.
Winter 2025-2026 - Added distribution on Anthropic, Finster AI, Samaya AI, and Rogo.
This stands in contrast to the "walled garden" strategy of some networks, such as AlphaSights, Guidepoint, and In Practise, which publish their content exclusively on their proprietary platforms and don't distribute it to 3rd parties. See our deep dive on expert transcript library strategies here.
