Build Versus Partner: The Strategic Decision
Agencies entering experiential marketing face fundamental decisions about technical capability development. Building internal teams provides control, IP ownership, and margin capture but requires substantial investment and ongoing overhead. Partnering with specialized technical vendors offers flexibility and reduced fixed costs but creates dependency and margin sharing. Neither approach universally dominates—optimal strategy depends on agency size, experiential revenue volumes, growth trajectory, and strategic positioning.
Build-in-house makes sense when: experiential work represents 40%+ of agency revenue justifying specialized resources, projects require frequent small technical tasks inefficient to outsource, IP ownership and proprietary capabilities provide competitive differentiation, and talent acquisition/retention proves feasible in agency location. Partner-first approaches suit: agencies with occasional experiential projects insufficient to maintain full-time resources, rapidly growing experiential practices requiring flexible capacity scaling, and situations where technical talent acquisition proves challenging or expensive.
Hardware and Software Investment Requirements
Essential hardware for AR/VR development includes: high-performance development workstations (£2,000-£4,000 each), iOS and Android test device portfolios covering capability range (£3,000-£8,000 comprehensive sets), VR headsets for development and testing (£400-£1,200 per headset), and specialized equipment for specific applications (360° cameras for VR content, green screens for compositing, motion capture depending on requirements).
Software licensing costs include:
- Development tools: Unity Pro licenses (£1,800 annually per developer), Adobe Creative Cloud for asset creation (£650 annually per user), 3D modeling software like Blender (free) or Cinema 4D (£700+ annually)
- Platform tools: Apple Developer Program (£99 annually), Google Play Developer (£25 one-time), specialized AR/VR SDKs (pricing varies)
- Project management: Collaboration tools (£10-£30 per user monthly), version control systems (free to £20 per user monthly), testing platforms (£50-£300 monthly)
- Third-party services: Cloud hosting (£50-£500+ monthly depending on scale), analytics platforms (£0-£200 monthly), asset libraries and stock content
A small agency building minimal internal capability might invest £15,000-£25,000 initial hardware/software with £5,000-£10,000 annual recurring costs. Mid-size agencies with dedicated experiential teams typically invest £40,000-£80,000 initially with £15,000-£30,000 annual recurring expenses for three-person technical team.
Talent Acquisition and Skill Development Paths
Technical talent for experiential work remains scarce and expensive. Market rates for experienced AR/VR developers range £45,000-£80,000 annually in UK regions, with London commanding 20-30% premiums. 3D artists and technical designers command £35,000-£60,000, while junior developers start £28,000-£40,000.
Talent acquisition strategies include: hiring experienced specialists for immediate capability (expensive but reduces time-to-productivity), developing junior talent through training programs (cheaper but requires mentorship investment and patience), converting existing agency developers through upskilling (leverages institutional knowledge but requires capability gaps filling), and hybrid models combining senior hires with junior development and external partners for capacity overflow.
Skill development paths for existing teams include: online courses and certifications in Unity, AR frameworks, and 3D development (£500-£2,000 per person), conference attendance and networking (£1,000-£3,000 per event including travel), dedicated learning time allocation (20% time for skill development common in tech companies), and mentorship or consulting relationships with external experts providing guidance (£150-£300 per hour typical).

Utilization Rates and ROI Calculations
Internal technical resources must maintain sufficient utilization justifying employment costs. Target billable utilization rates typically range 60-75% for technical staff (lower than account management due to training, internal projects, and tool development time). Below 50% utilization, partnership models typically prove more economical than employment.
ROI calculation should compare: Total cost of ownership for internal team (salaries, benefits, equipment, software, training, overhead allocation) against equivalent external partner costs at projected volume. Example scenario: Mid-level developer costs agency £65,000 annually (£45,000 salary + £20,000 benefits/overhead/equipment). At 65% utilization, developer delivers approximately 1,200 billable hours annually. If agency bills technical work at £80-£120 per hour and pays partners £50-£70 per hour, internal development becomes economically attractive above £100,000-£150,000 annual technical revenue.
Project Management Tools and Testing Infrastructure
Effective experiential delivery requires appropriate tooling beyond development environments. Essential project management infrastructure includes: task tracking systems (Jira, Asana, Monday.com) coordinating development and creative workflows, version control (Git, GitHub, GitLab) managing code and asset versions, documentation platforms (Notion, Confluence) capturing decisions and technical specifications, and communication tools (Slack, Teams) facilitating collaboration.
Testing infrastructure proves critical for quality: device testing labs with diverse hardware covering customer device range, automated testing frameworks catching regressions and compatibility issues, beta testing programs providing pre-launch user feedback, and analytics implementation enabling post-launch monitoring and optimization.
Capability Maturity Models and Growth Frameworks
Level 1 (Partner-Dependent): Agency lacks internal technical resources, relies entirely on partners for delivery. Appropriate for agencies with occasional experiential projects or just entering space. Investment: £5,000-£15,000 annually in tools/learning. Staff: Account managers with basic technical literacy.
Level 2 (Hybrid Model): Agency maintains single technical generalist managing partners and handling simple implementations. Suitable for £200,000-£500,000 annual experiential revenue. Investment: £30,000-£50,000 (salary + equipment). Staff: 1 technical developer/producer plus partner relationships.
Level 3 (Core Team): Dedicated 2-3 person technical team handling majority of work with occasional specialized partner support. Appropriate for £500,000-£1,500,000 experiential revenue. Investment: £150,000-£250,000 annually. Staff: Lead developer, junior developer, 3D artist/technical designer.
Level 4 (Full Capability): Comprehensive 5-8 person technical department with specialized roles and minimal external dependency. Suits agencies with £1,500,000+ experiential revenue as major service line. Investment: £400,000-£700,000+ annually. Staff: Technical director, senior and junior developers, 3D artists, QA specialists.
Progression between levels should follow revenue validation—avoid building capacity ahead of demand. Most agencies benefit from 6-12 month lag between revenue achievement and capability investment, ensuring experiential practice sustainability before fixed cost commitments. Mature agencies often maintain Level 3 capabilities with strategic partner relationships providing Level 4 capacity flexibility without permanent overhead—optimal balance for many mid-market agencies.
