Question 1

How long does it take to hire an AI engineer in Europe?

Accepted Answer

3-6 months to hire, then 1-3 months ramp-up. From decision to first working AI system: 6-12 months minimum. Realistically, 3-6 months from job posting to hired candidate, often longer for senior profiles. After that, factor in 1-3 months of onboarding and ramp-up before genuinely productive output. From decision to first working AI system, you are typically looking at 6-12 months at minimum.

Question 2

What does an in-house AI engineer cost in Western Europe?

Accepted Answer

Base salary €70K-€100K+. All-in cost (salary + social contributions + benefits + equipment) is €90K-€150K+ per person per year. Base salaries for AI engineers in Western Europe range from €70,000 to €100,000+ depending on seniority and location. Total employment cost including employer social contributions, benefits, and equipment is typically 1.3x to 1.5x base salary, putting the all-in cost at €90,000 to €150,000+ per year per person.

Question 3

When does building an in-house AI team actually make sense?

Accepted Answer

When AI is a core product function, you need continuous full-time development, and your revenue is $100M+. Below that scale, the economics strongly favor outsourcing. When AI is a core component of your product or revenue model, when you need continuous full-time AI development rather than episodic projects, and when your revenue scale at $100M+ can absorb the overhead of a full technical team. At that scale and with those continuous needs, the long-term economics of an internal team can be justified.

Question 4

Can Nexum work alongside an existing internal tech team?

Accepted Answer

Yes, and this is common. Nexum handles specialized AI implementation while your internal team manages existing infrastructure. Nexum can train your team and structure a full handoff when the time is right. Yes, and this is common. Many clients have a small internal IT team that handles existing infrastructure while Nexum handles specialized AI implementation they do not have the expertise for. Nexum can train your internal team, document everything, and eventually hand off ongoing optimization if that becomes the right structure.

Question 5

What happens after Nexum delivers the system?

Accepted Answer

Ongoing support is built into the engagement. Systems are documented, your team is trained, and Nexum continues optimizing. If you want to bring things fully in-house later, the handoff is structured to make that possible. Ongoing support is built into Nexum's engagement model. You are not left with a black box that no one understands. Systems are documented, your team is trained on how to use and monitor them, and Nexum provides continued optimization. If at some point you want to bring things fully in-house, Nexum structures the handoff to make that possible.

Question 6

Is outsourcing AI to Nexum better than hiring in-house for SMBs?

Accepted Answer

Yes, for SMBs ($5M-$50M). Hiring takes 6-12 months and costs €90K-€150K+/year per person. Nexum delivers a full AI team in weeks at a fraction of that cost. For SMBs in the $5M-$50M range, yes. Building an in-house AI team is the wrong allocation of capital and time at that scale. The hiring process takes 6-12 months minimum, the cost is €90,000-€150,000+ per person annually, and one or two engineers cannot cover the breadth of modern AI capabilities a business actually needs. Nexum gives those businesses access to a full team of specialists starting immediately, at a fraction of the annual cost.

Question 7

What is the risk of a bad AI hire vs outsourcing?

Accepted Answer

A mis-hire at the AI engineer level typically costs €150K-€250K total including lost salary, recruitment fees, severance, and delayed implementation. Outsourcing eliminates this risk. A mis-hire at the AI engineer level costs 6-12 months of salary plus recruitment fees, severance, and the opportunity cost of delayed implementation. That is €100,000-€200,000 in direct cost before accounting for the time lost. Outsourcing to Nexum eliminates hiring risk entirely: if the engagement is not delivering, the contract structure allows for adjustment without the legal and financial overhead of an employment termination.

Question 8

How many AI specialists does Nexum provide vs a single hire?

Accepted Answer

A single hire covers 1-2 specializations. Nexum brings a full team across 5+ domains: workflow automation, LLM integration, customer service AI, voice agents, and self-hosted AI. A single in-house AI hire covers 1-2 specializations deeply. Nexum brings a team covering workflow automation, LLM integration, customer service AI, voice agents, and self-hosted AI: breadth that would require 3-4 specialized hires to replicate internally, at a cost of €360,000-€600,000+ per year.
