Propeller

• 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.

Propeller engagements appear to start with an opportunity/discovery phase to understand the client’s business, users, stakeholders and goals, then move into planning, wireframing/design, build or migration work, and ongoing management with regular meetings and reporting. Clients consistently describe a collaborative process where Propeller acts like an extension of the team, handles delivery internally, and continues optimization/support after launch.

1. 1

   Run discovery and opportunity analysis

   Propeller begins by understanding the client’s business, target audience, competitors, pain points, and success criteria. Reviewers describe many early meetings to learn the brand and requirements, while Propeller’s own service pages describe discovery sessions and initial analysis before strategy is set.

2. 2

   Agree scope, objectives, and rollout plan

   After discovery, Propeller agrees the scope of work and refines plans with stakeholders around business objectives. Clients describe a defined project and roll-out plan, sometimes starting with one template or workstream first, and Propeller is said to provide timelines, steps, team responsibilities, and points of contact.

3. 3

   Create wireframes, templates, and strategic recommendations

   Once direction is set, Propeller moves into wireframing and design, often taking the lead on design structure while incorporating client input, content, and brand context. Reviews also mention competitor analysis, template redevelopment, UX thinking, and planning store or site architecture as part of this phase.

4. 4

   Build, migrate, and integrate the solution

   Propeller then carries out the implementation work internally, such as website development, replatforming, API redevelopment, headless CMS migration, Shopify Plus builds, CRM or marketing integrations, and technical SEO improvements. Clients describe Propeller as handling development delivery while bringing required functionality to life in the backend and frontend.

5. 5

   Review, tweak, and approve deliverables

   Before and around launch, clients review outputs and request adjustments where needed. Review evidence suggests Propeller is responsive to change requests, incorporates tweaks, and in some projects delivered work with only minimal revisions needed from the client side.

6. 6

   Manage launch and day-to-day delivery

   During execution and rollout, Propeller maintains close communication through regular informal contact, management meetings, and active project management against timelines and gantt charts. Clients repeatedly describe the team as timely, communicative, flexible, and functioning as an extension of the internal marketing team.

7. 7

   Report performance and continue optimisation

   After launch, Propeller continues with reporting, support, and optimisation rather than ending at handoff. Reviewers mention monthly reporting and quarterly strategy meetings, while Propeller’s own pages describe bespoke dashboards, analytics reviews, and ongoing optimisation to refine performance over time.
