Why B2C Personalisation Models Fail in B2B
B2C personalisation is fundamentally individual — one consumer, one set of preferences, one purchase decision. The data model, the decisioning logic, and the measurement framework are all built around individual behaviour. When B2B organisations adopt B2C personalisation approaches, they encounter a fundamental structural mismatch: the B2B buying decision is not made by an individual; it is made by a committee of four to ten stakeholders with different roles, different priorities, and different information needs.
A personalisation system designed for individual decisioning will optimise for the wrong unit of analysis in a B2B context. Showing the right content to the economic buyer does not matter if the technical evaluator and the end user have not been addressed. Account-level intent — the aggregate signal across all stakeholders — is more predictive of purchasing behaviour than any individual signal.
The Account-Role Content Matrix
B2B personalisation requires two dimensions of content targeting: the account dimension (which company, at what stage in the account journey, with what intent signals) and the role dimension (which stakeholder within the account, with what role-specific information needs). The intersection of these two dimensions — account context and role context — defines the appropriate content for each stakeholder interaction.
The account-role content matrix maps content components to both dimensions. A product capability overview for an enterprise financial services account at evaluation stage differs from the same capability overview for a mid-market technology account at awareness stage — and both differ from the version of the same content appropriate for a technical evaluator versus an economic buyer in the same account.
Key Takeaways
1. B2C personalisation models fail in B2B because they optimise for the individual when the relevant unit of analysis is the buying committee and the account.
2. B2B personalisation requires the account-role matrix — content targeted at the intersection of account context (stage, industry, intent) and role context (function, seniority, information need).
3. B2B personalisation measurement must account for the long sales cycle — attribution models designed for immediate conversion undercount the value of early-stage content that influences buying committee formation.
