About Us
Afori is completely changing the way of work in one of the world’s largest industries - insurance.
We’re an AI-first company with a vision to enable the insurance industry to embrace an agentic world. Afori is an AI platform built specifically for insurance brokers, designed to automate back-office tasks starting with the inbox. The Afori AI understands insurance processes, transforms unstructured communications into structured workflows, and frees brokers to focus on customer relationships and growth. Seamlessly integrated into Outlook, Afori is pragmatic, service-driven, and built with and for brokers. All while fostering a culture of radical candor, high performance, and relentless problem-solving for our customers, while having a lot of fun🙂
In just a few months, we have been able to launch a first beta product, raise a 12x oversubscribed €4m seed round from General Catalyst (early investors in Airbnb, Stripe, Mistral) and high profile angels. We are an experienced founder team with deep sector understanding, as well as deep understanding of how to scale a startup, having built Insurtech unicorn wefox (peak valuation of €4.5bn) before. You will get the opportunity to join a fast-scaling startup as one of the first employees and significantly shape the future of the company and the insurance industry.
Our Core Values:
🎯 Customer Centricity: We iterate with high velocity until we solve the core problems of our customers.
✨ Simplicity: We love simple solutions.
🛡️ Honesty: We live radical candor and psychological safety.
🔧 Hands-On Approach: We take ownership and deliver.
🏆 Dream Team: We play to win! And we always win together and we lose together.
✅ Solutions: Don’t worry, there is always a solution.

- Problem-Solving: Tackle complex challenges in data integration, workflow automation, and system reliability.
- Culture & Collaboration: Champion “radical candor” in code reviews and team discussions to elevate technical quality.
- Customer Alignment: Work business to ensure engineering efforts directly address customer pain points (Customer Centricity in action).
