Most software companies improve workflows.
We want to reinvent an industry.
Aizy is one of Europe’s fastest-growing AI software companies, combining artificial intelligence, automation and human expertise to deliver measurable business outcomes for customers.
In little over a year, we have grown to more than 500 customers, multiple millions in annual recurring revenue and a rapidly expanding international customer base.
Today, we are entering the next phase.
Our ambition is not to build another marketing platform.
Our ambition is to build the global category leader in AI-powered performance marketing.
A platform so intelligent, automated and effective that there simply is no better alternative.
To help us achieve that goal, we are looking for an exceptional Chief Technology Officer.
This is not a traditional CTO role.
This is a company-building role.
We are looking for a highly technical leader with a co-founder mindset. Someone who has built large-scale SaaS platforms, understands how world-class software companies are created and is willing to stay hands-on while building the future of Aizy.
You will work directly with founders Stefan Nuijten and Michiel Mol to define the long-term technology vision, accelerate product development and build a platform capable of serving customers worldwide.
You will become one of the most influential people within the company and play a critical role in shaping our future.
500+ active customers
Multi-million ARR business
International growth trajectory
Proprietary AI software platform
Backed by successful technology entrepreneurs and investors including Michiel Mol and Gijs Nagel
Ambition to become the global leader in AI-powered performance marketing
We believe the future belongs to software, not service businesses.
The companies that win the next decade will not be the companies with the most employees.
They will be the companies with the best technology.
Backend: .NET, Python
Frontend: SvelteKit, Angular
AI: Claude, OpenAI, LLMs, AI Agents and orchestration frameworks
Infrastructure: Cloud-native, scalable multi-tenant architecture

You will inherit a proven platform with real customers, real scale and a rapidly evolving AI-first product roadmap. As CTO, you will play a key role in shaping the future architecture, engineering standards and technology strategy that will support our next phase of growth.
You will lead the development of:
Autonomous AI-driven advertising systems
Multi-channel campaign optimization engines
Agentic AI workflows
Large-scale marketing intelligence infrastructure
Enterprise-grade SaaS architecture
International multi-tenant platform capabilities
Advanced forecasting, recommendation and decision engines
Future AI-native products that redefine how businesses acquire customers

Previous founder or co-founder experience
Within the next few years:
Aizy becomes a software-first organization
AI becomes our strongest competitive advantage
Product development velocity increases dramatically
Engineering becomes a world-class function
The platform scales globally
Aizy establishes itself as one of the leading AI software companies in Europe and beyond
Very few opportunities exist where you can:
Join after product-market fit
Join after significant revenue traction
Help shape a category-defining company
Work directly with experienced founders and investors
Build a globally scalable AI platform from an already proven foundation
This is not a role for someone who wants to maintain systems.
This is a role for someone who wants to build something exceptional.
Someone who believes technology can fundamentally change an industry.
Someone who wants to help create a company capable of reaching €100M+ ARR and becoming the global benchmark in AI-powered performance marketing.
