Blend Labs (BLND) concentration risks

Blend Labs' revenue base is concentrated among a relatively small set of large customers. In 2025, 25 customers each generating more than $1 million in annual revenue represented 75% of total revenue — a high-share dependency, meaning a large majority of revenue rests on a few dozen relationships rather than a broad, diversified customer base. Within that group, the top five customers alone accounted for 39% of revenue — a medium-share dependency, meaning a meaningful portion of the already-concentrated 75% sits with just five buyers. Both exposures share the same character: dependency on the continuity and expansion of specific customer relationships rather than a structural feature of Blend's business model. Because the top-five figure is nested inside the broader 25-customer figure, the two numbers describe the same underlying concentration at different levels of granularity rather than two separate risks — a loss of even one or two of the top five customers would ripple through both metrics simultaneously. For a company at Blend's stage, this level of customer dependency is the type of exposure most capable of moving the verdict quickly, since retention or expansion decisions by a small number of named-tier customers carry disproportionate influence over the top line relative to a more diversified peer.
