AI Implementation Comparison

Build vs Buy: In-House AI Team vs Implementation Partner

Should you hire AI engineers and build internally, or partner with specialists? Here's how to decide.

Quick Answer

Build in-house if AI is your core product and you need continuous iteration. Partner with specialists if AI enhances your operations but isn't your primary business—you'll get to production faster and avoid the overhead of recruiting scarce talent.

True Cost Comparison

Building In-House (Year 1)

  • Senior ML Engineer (1)€90-150K
  • Data Engineer (1)€70-110K
  • Recruiting costs (20% salary)€30-50K
  • Infrastructure & tooling€20-40K
  • Ramp-up time (3-6 months)Opportunity cost
  • Total Year 1€210-350K+

Implementation Partner (Typical Project)

  • AI Audit & roadmap2-4 weeks
  • Implementation6-12 weeks
  • Training & handoverIncluded
  • Time to production8-16 weeks total
  • InvestmentCustom-scoped

When to Build In-House

AI is your product.

If you're building an AI-powered product for customers, the capability needs to be core to your organization.

You need continuous iteration.

Daily model updates, constant experimentation, and tight integration with product development favor in-house teams.

You have 18+ months runway.

Building a team takes time. Expect 6+ months before meaningful output, 12+ months before the team is fully effective.

When to Partner with Specialists

AI improves operations, not your product.

If you're using AI to automate internal processes, improve customer service, or enhance decision-making, you don't need a permanent team.

You need results in weeks, not years.

Partners bring proven patterns and skip the learning curve. What takes a new team 6 months might take specialists 6 weeks.

AI talent is hard to find in your market.

Competition for ML engineers is fierce. A partner sidesteps the recruiting challenge entirely.

You want to reduce risk.

Partners have delivered similar projects before. They know what works and what doesn't. You benefit from their pattern recognition.

The Hybrid Approach

Many companies start with a partner to get initial AI systems into production, then build internal capability over time. This approach:

  • • Delivers quick wins while you recruit
  • • Provides a working reference implementation for new hires
  • • Reduces risk of bad early decisions
  • • Lets you validate AI ROI before committing to headcount

The Bottom Line

For most mid-market companies, partnering with AI specialists delivers faster results at lower risk. Building in-house makes sense when AI is your core business, not when it's enhancing operations. The hybrid approach—partner first, build later—often offers the best of both worlds.
