co-Founder (& CTO) Linkspan

Achmea Impact Ventures invests in digital startups that make an impact in health, work, finance, and sustainability. From our Venture Studio, we build new companies from scratch together with founders, providing funding, hands-on expertise, and the strong network of Achmea. Linkspan is one of those ventures.

Annually, there are more than 1.5 million ambulance trips in the Netherlands. Over 300,000 of these are for planned, non-urgent transport.

Scheduling these trips requires coordination between the requester and a dispatch center operator. This takes a lot of time, while the dispatch center is under pressure. Staff is scarce, workload and turnover are high, and many systems are outdated or have limited interoperability.

Linkspan is building an AI agent that independently goes through this intake with the requester and prepares the request. The operator maintains control and gives the final approval, but no longer has to conduct the entire conversation.

This agent is our starting point.

Through voice, AI, and integrations, we continue to build our ambition to make the dispatch center smarter, better connected, and future-proof. We take routine work off people's hands, enable systems to work together better, and free up scarce capacity for the calls where human judgment is most urgently needed.

The current team consists of founder Lauren Vierhoven and two part-time developers. Linkspan is being built with support from Achmea Impact Ventures.

We are working towards the go-live of our first AI agent. We are refining the agent's flow, building the necessary integrations, and testing with dispatch center operators.

Linkspan has a concrete first product, commitment from a customer, and traction in the market.

With the go-live, Linkspan will enter a new phase. The focus shifts from developing and testing to responsible production deployment, monitoring, and structural continuous development.

There is no better moment to join as a co-founding CTO.

The AI agent becomes part of an operational process within ambulance care.

• Voice, AI, telephony, integrations, and human assessment must connect reliably.

• Safety, privacy, reliability, and digital sovereignty carry heavy weight.

• Continuity is essential.

• Strict requirements apply to the way data is processed.

Today, Linkspan runs on TypeScript and Node.js, with an Express backend, a server-rendered UI, and SQLite with Drizzle. We use OpenRouter for LLMs and Twilio for voice and telephony.

We manage the server infrastructure ourselves with NixOS, Docker, Dokku, and nginx.

You join as CTO and full partner co-founder alongside Lauren.

Lauren focuses on customers, partners, and market development. He is strong at connecting parties, creating support, and translating customer feedback into opportunities for Linkspan. You complement that with technical depth, product focus, and sharp decision-making.

This is a strategic, but explicitly hands-on role. During the first six months, you are expected to spend approximately 80% of your time building yourself and 20% on architecture, product choices, and technical direction.

Your first assignment is concrete. You will prepare the AI agent for production, complete the necessary integrations, and ensure that the product can be reliably monitored, maintained, and continuously developed.

You will work closely with the developers and take technical leadership within the team.

The current stack is the starting point, not a fixed framework. You will receive the mandate to revise fundamental technical choices when reliability, safety, digital sovereignty, scalability, or the product direction demand it.

You will be technically ultimately responsible for:

• Architecture and infrastructure

• AI, voice, and telephony technology

• Integrations with operational systems

• Security, privacy, and digital sovereignty

• Monitoring, maintenance, and structural stability

• The design of the development process

• The technical leadership of the team

What we build after the go-live is intentionally still open. There are many possibilities, and that is precisely why sharp choices are required. Together with Lauren, you will determine what Linkspan focuses on next.

You will help build:

• The product and technology roadmap

• The setup of testable experiments

• The weighing of technical possibilities against customer value and scalability

• Conversations with customers and partners where technical considerations are decisive

At the end of the first six months:

• The AI agent runs reliably in production.

• The system independently handles the intake for non-urgent ambulance transport.

• The system functions consistently and verifiably.

• The AI agent is linked to the required external systems.

• The AI agent complies with applicable laws and regulations and with customer requirements regarding privacy, security, and digital sovereignty.

• Monitoring, maintenance, and continuous development are designed so that the product continues to function reliably even after the initial go-live.

• A technically substantiated roadmap exists for the next phase of Linkspan.

How you design that technically and strategically, you will determine together with Lauren.

• A true CTO and co-founder role, including equity in Linkspan

• Joining a startup with a concrete first product, commitment from a customer, and traction in the market

• Practical and financial backing from Achmea Impact Ventures

• Direct collaboration with organizations within ambulance care

• Direct influence on technology, product, and the company

• The combination of building yourself, technical leadership, and product strategy

• The mandate to redesign the technical architecture where necessary

• Equity plus hourly rate

• You have previously held technical ultimate responsibility within an early-stage startup and combined building yourself with architecture, product, and priority choices.

• You write production code yourself at a senior level.

• You have previously brought an LLM-driven product to production.

• You have experience with technical architecture and complex integrations.

• You can take responsibility for infrastructure and deployment yourself and make conscious choices about what you manage yourself and what you outsource.

• You know what privacy, security, and reliability mean for architecture and execution.

• You can provide technical direction to other developers.

• You can zoom out, set priorities, and stop work when it provides insufficient value.

• You think in hypotheses, experiments, and measurable results.

• You explain technical considerations clearly to customers and non-technical stakeholders.

Experience with healthcare technology, privacy-sensitive infrastructure, or another business-critical environment is a plus.

You are not just looking for a technical building assignment or management position. You are looking for co-ownership and want to bear responsibility for what Linkspan builds and becomes.
