[Marketing agency vs In-house team](https://potentpositioning.com/compare/agency-vs-in-house-marketing-team): A marketing agency is right when you need senior strategic capability without the cost of senior hires, or when you need specialist execution your in-house team can't credibly deliver. An in-house team is right when marketing is core to your daily operation and you can hire above market median. Most B2B businesses under £10m revenue use a hybrid: lean in-house plus an agency for strategy and execution.
[Boutique agency vs Network agency](https://potentpositioning.com/compare/boutique-vs-network-agency): Boutique agencies are right for B2B businesses under £50m revenue who want senior delivery and direct founder access. Network agencies are right for enterprises that need global rollouts, multi-market campaigns, or category-specific specialisms only large agencies hold.
[Specialist agency vs Full-service agency](https://potentpositioning.com/compare/specialist-vs-full-service-agency): Specialist agencies (SEO-only, paid-only, content-only) are right when positioning and brand are sorted and you need depth in one channel. Full-service agencies are right when you need coordinated brand, website and demand work — usually for B2B businesses building or rebuilding their marketing engine.
