Interim AI tech lead for your organisation.

An experienced technical leader who guides your AI initiative from strategy to production. Available as interim, fractional or project lead: pragmatic, vendor-independent and backed by a team.

Strategy & roadmapLLM architectureTeam buildingAI governance

A tech lead for AI is not a traditional CTO.

The role calls for someone who can design LLM architecture, justify vendor choices, lead an AI team and also perform hands-on senior code review. At the same time, they sit in the boardroom to bring your CFO, CISO and legal team on board with a roadmap that is both ambitious and achievable.

That combination is scarce in the Dutch market. Internal recruitment often takes several months before a suitable permanent AI tech lead is in place, and during that time your AI initiative falls behind. An interim AI tech lead bridges that gap, or fills the role on a structural fractional basis.

We provide this role from Appfront: senior engineering experience combined with AI-specific expertise in LLM gateways, RAG pipelines, evaluation frameworks and the associated governance. Not a staffing model with a loose freelancer, but a tech lead backed by a team of AI engineers and architects.

The role also differs fundamentally from a data science lead. Today's AI initiatives rarely revolve around training models yourself. They revolve around skilfully orchestrating LLM APIs, context and retrieval engineering, evaluation loops that safeguard quality, and infrastructure that is production-ready. Senior software architecture therefore now weighs more heavily than classic ML experience. An interim AI tech lead with us deliberately combines those two worlds.

Four engagements in which we fill the role.

The right format depends on your situation: whether you are temporarily replacing a departing lead, building something new from scratch, or want expertise on a fractional basis. In the first conversation we determine which variant fits.

Interim · ongoing engagement

Classic interim position

You bridge the period between a departing or yet-to-be-recruited permanent AI tech lead. Our interim takes over the full role: roadmap oversight, team leadership, vendor management and the stakeholder line with the board and the business. At the end, a clean handover to your new permanent lead.

Fractional CTO-AI · part-time, ongoing

Fractional AI tech lead

For scale-ups and mid-sized enterprises that need seniority in AI but do not yet have the volume for a full-time AI tech lead. A fixed one or two days per week, on an ongoing basis. Architecture decisions, hiring input, board participation and governance oversight: everything a full-time AI tech lead does, on a part-time basis.

Discovery + handover · short engagement

Discovery + handover

You want to recruit a permanent AI lead in the short term, but currently lack the seniority to set the right roadmap and architectural foundations. We run a short engagement in which we deliver the strategy, use-case prioritisation and initial platform architecture, then hand these over to the new permanent lead.

Project lead · scope-specific

Project lead for an AI platform

You have a concrete AI platform project that needs to move from pilot to production, such as a RAG system for your knowledge base, an agent flow for customer support, or an LLM gateway for your internal tooling. We provide a tech lead who designs, builds and delivers the project, with our AI engineers beneath them.

What an interim AI tech lead does for you in practice.

The role goes well beyond that of a conventional engineering manager. An AI programme calls for people who can carry strategy, architecture and governance at the same time. Our interim tech leads cover all of these dimensions.

If you would first like to set the direction before filling the leadership role, see our AI strategy offering.

  • Strategy and roadmapUse case prioritisation based on business impact and feasibility. Quarterly roadmap with clear owners, milestones and go/no-go moments.
  • Architecture and platformDesign of your LLM gateway, RAG infrastructure, evaluation suites, prompt management and observability layer. Vendor-neutral, with no lock-in.
  • Team building and recruitmentInterim recruitment of AI and ML engineers, profile development, technical interviews, and onboarding of new hires.
  • Hands-on senior workArchitect-level coding, code reviews on critical pull requests, and prompt engineering reviews. No junior-level coding, but personal ownership of the critical decision points.
  • Governance and complianceMapping to the AI Act, overlap with GDPR and DORA where relevant, ISO 27001 framework, audit trail requirements and data classification for LLM inputs.
  • Vendor managementNegotiating and evaluating contracts with Anthropic, OpenAI, Azure OpenAI, AWS Bedrock and Google Vertex. Multi-provider strategy where it makes sense.
  • Stakeholder managementConnecting the board, CFO, CISO, legal and the business. Explaining AI in plain language to the non-technical layers of your organisation.
  • Knowledge transferStructured handover to your internal tech lead or permanent successor. Documentation, decision logs and a clean project status.

When an interim AI tech lead is the right fit.

Five situations in which we typically fill this role. If you recognise your organisation here, the conversation is likely to be worthwhile.

Scale-up without a senior

You want to take on AI without a senior AI engineer

The ambition is there, and so is the budget, but the seniority is missing. You want to avoid making the mistake of starting with juniors without anyone to provide direction. Our interim sets up the platform and builds the team beneath it.

Enterprise bridging

Your previous AI tech lead has left

You are caught between a departed lead and a permanent hire yet to be recruited. Nobody is keeping an eye on the roadmap, vendor contracts are rolling on, and the team is losing momentum. We fill the gap until your new permanent lead is on board.

Pilot to production

The AI pilot works, but production has stalled

You have a proof of concept running in a Jupyter notebook or as a prototype on a single machine. Production requires observability, evaluation suites, security and SRE practices, work that a data scientist cannot carry alone.

Strategy plus execution

You want AI strategy at board level

A fractional AI CTO who joins your board meetings, substantiates AI investments for investors or the parent company, and at the same time oversees delivery. Strategy decks that also translate into practice.

Consultancy with an AI component

Your consultancy engagements need AI depth

You are an advisory firm running client engagements with an AI component, and you want to hire a senior tech lead on a secondment basis for the technical side without overburdening your own team.

Compliance pressure

You need to make the AI Act and GDPR operational

The regulator or your legal team is sounding the alarm. You need someone who can map the AI Act onto your use cases, establish the overlap with GDPR and DORA, and design governance processes that remain workable for your team.

Strategic reassessment

You are uncertain about your current AI direction

The roadmap you set some time ago now feels outdated, vendor choices are being questioned, or the first results are falling short of expectations. An external senior tech lead can look at the decisions with fresh eyes and re-establish the scope on a sound footing.

Investor pressure

Your investors are asking about AI positioning

For scale-ups, AI is playing an increasingly prominent role in investor questions. A fractional AI tech lead can take part in due diligence conversations, provide technical substantiation during funding rounds, and support the AI claims in your pitch with realistic roadmaps.

What sets our positioning apart.

There are several ways to temporarily fill an AI leadership role. Below is how we position ourselves relative to the usual alternatives.

Vs staffing agency

Leadership and builders in one

A conventional staffing agency supplies individual engineers, not tech leadership. We combine both: a senior AI tech lead with operational authority, supported by builders they can call on directly wherever needed.

Vs freelance CTO

Team backing and continuity

A freelance CTO is an individual with no back-up. Our tech leads are employees or long-term partners of Appfront. If someone becomes unavailable, we have a successor with the same expertise. Knowledge stays within the firm, not just with one person.

Vs enterprise consultancy

Pragmatic and mid-market focused

Firms such as Accenture, Capgemini, Deloitte and EY have strong AI practices, but they are generally built for enterprise budgets and large programmes. For scale-ups and mid-sized enterprises, that is overkill. We work more pragmatically and with a mid-market focus.

Vs in-house recruitment

Available within weeks

Recruiting a senior AI tech lead in-house is structurally slow: scarce supply, high salaries and lengthy hiring cycles. We are available as soon as we have made a match, often within a few weeks of the first introduction.

How an engagement works.

1

Introduction

A conversation in which we understand where you stand: what your AI ambitions are, what team you have, what compliance pressures apply, and what form of leadership fits best at this moment. Not a sales pitch, but advisory.

2

Matching and intake

We connect you with one of our senior tech leads. Before starting, there is a thorough intake: culture, codebase status, stakeholder landscape and the main challenges at the outset. Concrete scope and goals are set down on paper.

3

First sprints

The interim lead starts with a rapid assessment of the team, codebase and governance, and within a few weeks delivers a status report and a sharpened roadmap. They then continue to work alongside you as tech lead.

4

Ongoing involvement

Weekly check-ins with you or your board, monthly roadmap reviews, and continuous operational leadership of your AI team. Our other AI engineers and architects are available for specific deep-dives where useful.

5

Handover

At the end, a structured handover to your new permanent lead or internal successor. Decision logs, architecture documentation, vendor contracts, and an ongoing roadmap that can be executed immediately.

Compliance is not an afterthought.

The EU AI Act is in force, GDPR obligations overlap with AI systems, and sector-specific rules such as DORA impose additional responsibilities. An interim AI tech lead needs to understand this landscape, not as a lawyer, but as a technical translator between legal and engineering.

Our leads work with your legal team on a concrete mapping: which use case falls into which risk category under the AI Act, which documentation obligations follow from that, and how to make this operational without paralysing your development team. For broader support on compliance, see also our AI literacy training.

  • AI Act mappingFor each use case, determining which risk category applies (prohibited, high-risk, limited-risk, minimal-risk) and what documentation and human oversight that entails.
  • GDPR overlapDetermining where personal data ends up in your LLM flow, which processor relationships that creates, and which DPIA steps are needed for your AI use cases.
  • DORA where relevantFor financial institutions: an AI platform falls under operational resilience requirements. We align it with your broader DORA implementation without duplicated effort.
  • ISO 27001 contextAligning your AI platform with an existing ISO 27001 organisation without the governance overhead slowing down build pace.
  • Audit trail by designLogging at prompt level, model version, cost and output. Prepared for internal audits and for client questions about responsible AI use.

Frequently asked questions.

What clients typically want to know before we start.

What exactly is an interim AI tech lead?
An experienced technical leader who fills the role of AI tech lead in your organisation on a temporary basis. Someone with a senior engineering background and AI-specific expertise in LLM architecture, governance and team leadership. Not a loose freelancer, but a professional backed by a team of AI engineers and architects.
What is the difference between interim and fractional?
An interim tech lead replaces a departing or not-yet-recruited permanent lead, typically full-time or nearly full-time for a defined period. A fractional AI CTO is an ongoing, part-time arrangement (often a day or two per week) for organisations that want senior leadership but do not yet have the volume for a full-time AI tech lead.
How long does such an engagement typically last?
It varies considerably by situation. An interim bridging role often lasts several months, depending on how quickly permanent recruitment progresses. A discovery and handover engagement is shorter, while a fractional arrangement typically runs over a longer period. In the first phase we discuss a realistic timeframe with you, without committing to hard figures up front.
When is this a better fit than in-house recruitment?
Recruiting a senior AI tech lead in-house almost always takes several months, given the scarce pool of candidates for this role. If you cannot afford to pause your AI initiative during that period, an interim fills the gap. Additionally, for an AI pilot that is just moving towards production, you may not yet know what permanent seniority you need, and a fractional arrangement gives you time to determine that.
What is the difference from an enterprise consultancy?
Firms such as Accenture, Capgemini and the Big Four deliver good work for enterprise budgets, but are generally not the right choice for scale-ups and mid-sized enterprises, as their overhead and methodological weight do not fit. We are more pragmatic, mid-market oriented, and provide an individual tech lead rather than a team of consultants with PowerPoint decks. For the substantive implementation, see our page on enterprise AI implementation.
And how does this compare to a freelance CTO?
A standalone freelance CTO has no team, no retention safety net and no dedicated AI team behind them. Our interim tech leads work from Appfront and can at any time bring in AI engineers, ML engineers or platform engineers from our team for specific deep dives, without you having to recruit or contract those people separately.
What determines the cost of an interim AI tech lead?
The format (interim, fractional, project lead), the weekly time commitment required, the duration of the engagement and the seniority that suits your situation. We discuss this transparently in the first phase, with no surprises afterwards. For concrete figures, we arrange a conversation in which we first clarify your situation and scope.
How does the recruitment of a successor work?
Our interim AI tech lead can take an active part in the hiring process for your permanent successor: building the profile, running technical intake interviews, reviewing take-home assignments, and making the final go/no-go decision. A structured knowledge transfer is standard in every engagement, so your new permanent lead gets up to speed quickly.
Are you vendor-locked?
No. We have no reseller agreements with Anthropic, OpenAI, Microsoft Azure, AWS or Google. This means our vendor choices are based purely on your situation, not on a commercial incentive from a platform partner. Multi-provider strategies are often wiser than strict lock-in. We also regularly build custom LLM integrations where several providers run side by side.
