Frequently Asked Questions
What is a marketing agency?
Full-service brand growth, strategy, and channel mix. On Inflowave, every listed marketing agency is manually verified - we check platform partnerships (Meta / TikTok), real case studies with numbers, and active Inflowave usage before listing.
How much does a marketing agency cost in 2026?
Boutique (1-5 people): $1,500-$4,000/mo. Mid-size (10-30 people): $4,000-$15,000/mo. Specialist marketing boutiques in high-ticket niches can charge $25,000+. Performance / revenue-share billing is increasingly common - confirm the model before signing.
How do I choose the right marketing agency?
Filter on three things: (1) a platform partnership badge (Meta Business Partner, TikTok Marketing Partner); (2) specific, numeric case studies rather than "we grew their brand"; (3) specialization match - pick an agency where marketing is a primary specialty, not one of twelve bundled services. Every agency below shows verified metrics and case studies.
