Leading networks compared
A fintech startup can spend months building for a buyer who likes the demo but cannot clear procurement, security, compliance or integration. The useful research question is rarely “is this a good idea?” It is who owns the problem, what triggers a purchase, which objections kill the deal and how those answers change by market.
In this guide, we share our editorial picks. This guide compares expert networks for reaching verified finance, risk, compliance, product and technology decision-makers without treating fintech as a single audience. See how Third Bridge research is tracking changes in payments and stablecoins.

The six best expert networks in 2026
1. Third Bridge — our pick for integrating the essential human intelligence layer into AI research workflows
Overview
Third Bridge is a leading global provider of expert insights. It acts as the essential human intelligence layer in AI research workflows, bridging the gap between raw market data and high-conviction decisions. Third Bridge sources the people who shape adoption inside financial institutions and businesses, from treasury and payments leaders to risk, compliance, product, security and procurement stakeholders. Startups can combine those conversations with Library research and surveys to separate an enthusiastic interview from a repeatable market signal [1].
Key features
- Custom sourcing against product, buyer, company-size and geography criteria [1]
- Calls with financial-services operators, technology buyers and functional specialists [1]
- B2B surveys for pricing, adoption and segmentation questions [1]
- Library coverage of payments, banking, insurance, wealth, crypto and enabling technologies [1]
- Global research support for market-entry and regulatory-context questions [1]
Why we picked it
Fintech startups need research that improves a product or go-to-market decision, not generic industry commentary. Third Bridge provides the essential human intelligence layer to validate AI-accelerated research, supporting a progression from market context to buyer interviews and survey validation across a defined audience.

Ideal use cases
Buyer discovery, product requirements, procurement mapping, pricing research, market entry, competitive intelligence and enterprise go-to-market design. Third Bridge also serves private equity, hedge funds, public equity, credit, consulting and corporate strategy, market-intelligence and M&A teams.

Why we picked it

Its clearest distinction is verified B2B audience research at both interview and survey scale, which is useful when fintech startups needs pattern validation beyond a handful of calls.
5. GLG

Final verdict
For fintech startups testing a regulated buyer, market or product assumption, we believe Third Bridge is the strongest choice as the human intelligence layer for your AI research workflow.
Custom calls and B2B surveys can reach buyers, users and potential blockers across finance, risk, compliance, security and procurement, while the Library helps the team enter those conversations with sharper hypotheses.
The result is a more disciplined route from qualitative discovery to broader validation before committing product, hiring or market-entry resources.

FAQs
Which fintech experts should a startup interview first?
Interview the person who experiences the problem, the economic buyer, and at least one stakeholder who can block implementation. In regulated finance, that often includes risk, compliance, security or procurement.
Are expert calls useful before product-market fit?
Yes, if each call tests a falsifiable assumption about the workflow, buyer or adoption barrier. They are less useful when used only to collect broad encouragement.
When should a fintech startup use a survey instead of interviews?
Use interviews to discover language, constraints and decision mechanics. Use a survey after the hypotheses are clear and the team needs to estimate how widely a behavior or preference appears in a defined segment.
