Definition
A Customer Advisory Board (CAB) is a formal group of strategic customers who meet regularly to provide product feedback, validate roadmap priorities, and share market perspective. Unlike ad hoc customer interviews or NPS surveys, a CAB provides structured, ongoing input from customers who represent your target segments and have deep enough usage to offer informed opinions.
A typical CAB has 8-15 members, meets quarterly (with ad hoc calls between meetings), and includes a mix of roles -- usually the executive sponsor, the power user or admin, or both. Members serve 1-2 year terms with staggered rotation so you maintain continuity while bringing in new voices. Salesforce, HubSpot, and Pendo all run CABs as a core input to their product planning process.
The CAB is not a user group, a beta program, or a support escalation path. It's a strategic relationship where customers give candid feedback in exchange for influence and access. The best CABs operate as a two-way partnership: you share roadmap direction and early concepts, they share market trends, competitive intel, and honest assessment of your product's gaps.
Why It Matters for Product Managers
PMs often struggle with the quality-versus-quantity tradeoff in customer research. Surveys give you scale but shallow data. Individual interviews give depth but small samples. A CAB offers something in between: deep, contextualized feedback from customers who understand your product well enough to give nuanced input, delivered on a regular cadence.
Pendo's product team credits their CAB with catching a major prioritization mistake early. The PM team planned to invest a quarter in building advanced analytics dashboards, but CAB members consistently said they'd rather have better in-app guidance tools. That feedback redirected $500K+ in engineering investment toward what became one of Pendo's core differentiators.
CABs also reduce the "loudest voice" problem in customer research. Without a structured advisory group, product decisions get skewed by whichever customer happens to have the CEO's ear or the biggest contract. A CAB gives you a representative panel that counterbalances individual requests with group perspective.
Beyond product input, CABs generate side benefits: customer advocates who willingly write case studies, reference calls for prospects, and beta testers who give thorough feedback because they have a relationship with your team.

Customer development is the broader research practice that a CAB supports -- the CAB provides a standing panel for ongoing discovery. Qualitative research techniques (interviewing, contextual inquiry) should inform how you facilitate CAB discussions. Your persona definitions help you recruit a representative CAB that covers your key user and buyer types.
