Propeller Pricing & Cost

• Pricing model: Primarily custom-quoted agency engagements: per-project for website/design/development work, ongoing monthly retainer for digital marketing/performance services, and at least one named always-on growth retainer product (Gravity AI).
• Starting price: $25,000 minimum project budget
• Typical range: $25,000 - $50,000 per project
• Billing: Custom quote; project-based for builds and redesigns, monthly retainer for ongoing marketing/performance work. Propeller’s own site also describes Gravity AI as "one retainer" / an "always-on growth retainer."
• Contract terms: Propeller states its AI Search solution starts with an initial six-month programme, followed by a tailored retainer. No general agency-wide contract term was found.

I found concrete public pricing signals, but they are mostly directory-style figures rather than a full official rate card on Propeller’s own site. DesignRush lists Propeller UK with a minimal budget of $25,000-$50,000 and an average hourly rate of $149/hr; Onelittleweb separately lists a $10,000+ minimum project cost, but because the most coherent published unit is project budget, the range above uses the DesignRush project-budget band. On Propeller’s own website, pricing is custom and quote-led: their Shopify page says engagements may be hourly or fixed-price and mentions maintenance packages/retainers, while Gravity AI is explicitly described as a single ongoing retainer and their AI Search offering explicitly starts with a six-month programme before moving to a tailored retainer.
