How do I select a B2B marketing agency?

How do you choose a vertical-specialist B2B marketing agency for tech and fintech?

Choose a vertical-specialist B2B marketing agency by validating pipeline impact in 3-5 same-vertical case studies with CRM opportunity reporting. Require proof of marketing-sourced pipeline and win-rate changes across 6-18 month buying cycles, not just MQL volume. For B2B fintech like payments infrastructure or regtech, demand anonymized opportunity data that shows stage progression through committee-driven decisions involving security, finance, and IT. If they can't explain your competitive landscape in plain English or show opportunity movement, walk away, you need vertical fluency in the questions they ask, not logos on their slides.
