The Integration Partner Playbook: How One AI Agency Built a €30K/Month Business Without Sales

An AI automation agency reveals how they built a profitable business by partnering with software companies – achieving 100% conversion rates and 80% profit margins without a sales team.
The Integration Partner Model
While most AI agencies struggle with lead generation and sales, AI Union found a unique arbitrage: becoming the official integration partner for emerging AI software companies. The model is elegantly simple – software companies sell integration packages, and AI Union handles the technical implementation.
| Traditional Agency Model | Integration Partner Model |
|---|---|
| High CAC via ads/content | Zero customer acquisition cost |
| 10-50% conversion rates | 100% conversion rate |
| Complex custom projects | Standardized offerings |
| Heavy sales burden | Sales handled by partner |
The Technical Implementation
AI Union productized their services into two tiers:
- Basic Setup (€1,000): 8 hours of configuration, basic prompting, and calendar integration
- API Integration (€2,000): 16 hours of development connecting voice AI to client systems via custom middleware and automation
The team leverages AI-powered workflow automation to streamline delivery, including using Firefly AI transcripts to auto-generate initial voice agent prompts.
Partner Selection Strategy
The ideal software partner has three key characteristics:
- Complex enough product to require expertise (unlike Calendly)
- Small enough team (10-15 people) to benefit from outsourcing
- Strong market presence but limited internal implementation resources
Scaling Through Systems
AI Union built robust systems to scale efficiently:
- Standardized onboarding forms and scoping processes
- Shared CRM dashboard for project tracking
- Weekly alignment calls with software partners
- Comprehensive training documentation for new developers
This systematization enabled them to grow without founder involvement, as highlighted in recent analysis of AI entrepreneurship costs.
The SaaS Evolution
The high volume of integration projects (150+ in 4 months) revealed patterns in client needs, particularly around outbound calling automation. This led to the development of SalesFrank, a productized version of their most common integration patterns.
