When do you choose which?
Choose an AI agency if you:
- Are an SME or growing business (without a large internal AI team)
- Want results within 2 months
- Don't have an internal tech team (or don't want to burden it)
- Want to integrate AI with existing software
- Want proven solutions, not experiments
- Want to keep costs predictable
Consider building in-house if you:
- Are a large organisation with your own tech team
- Want to build an internal AI team
- Have 10+ developers available
- See AI as a core competency
- Find 6-12 months time-to-market acceptable
- Have budget for €150,000+/year

Frequently asked questions
When do I choose an AI agency like UnifyAI?
When you want quick results without building an internal AI team. An AI agency delivers working solutions in 6-8 weeks, including integration with your existing software. Ideal for SMEs and growing businesses that want to deploy AI without a large upfront investment in personnel.
When is building in-house better?
When you have a large internal tech team (10+ developers), want to develop AI as a core competency, and are prepared to invest 6-12 months for first results. This is especially relevant for tech companies or organisations with 500+ employees.
What does it cost to build AI yourself vs. engaging an agency?
Building in-house: €150,000-€500,000+ per year (salary AI engineer + tooling + cloud + trial-and-error). AI agency: €1,000-€40,000+ per project depending on scope, plus €50-€200+/agent/month hosting. For most SMEs, an agency is 5-10x more cost-effective.
Can I switch from agency to in-house later?
Yes. With UnifyAI you get full ownership of the solution. We document everything and transfer knowledge if you want to build an internal team later. Many clients start with an agency and bring specific parts in-house after 1-2 years.
