About us
Software engineers with firsthand e-commerce experience.
We’re Flyweight, a software startup from Mannheim, Germany. We build AI that understands your products, helps your customers and takes work off your team’s hands. We like making software that earns its place in your working day.
We know e-commerce from running our own brand and online store. Today, we bring that experience to the software and automation we build for brands on Shopify.
Our focus: development over sales
We skipped the separate sales team. You have one dedicated contact on our team with hands-on software development experience.
How it started: three developers, one shared passion.
Marc, Matthias and Christian met more than 13 years ago while studying business informatics alongside their jobs. They shared a love of building software and a curiosity about how much easier it could make everyday work.
Alongside careers in finance and at BASF, they spent their spare time on their own projects. There was plenty of enthusiasm and learning, but little financial success at first. In 2018, they founded Flyweight with a clear idea: build a data-driven e-commerce business, automate as much as possible and turn it into their full-time work.
2018 to 2021
Monte Stivo: firsthand experience in e-commerce.
With their brand Monte Stivo, Flyweight’s founders sold more than 100,000 children’s binoculars and reached around €3 million in annual revenue. They built the business alongside their jobs and studies, making automation central to the operation from the start.
Running their own online store gave them a practical understanding of everyday e-commerce work and where good software can make a real difference.
The founders sold Monte Stivo in mid-2021. The sale allowed them to focus fully on their longstanding passion: building software and automating processes. Their experience running an e-commerce business became the foundation for Flyweight AI.
From the founders’ Shopify store to Flyweight AI.
Before the sale in 2021
Their own store as the starting point.
Inspired by Christian’s master’s thesis, the founders began experimenting with graph databases before selling Monte Stivo. Their own Shopify store was the first data source they connected. The goal was to link data in a way that made its relationships useful in everyday work.
2022 and 2023
ChatGPT sparks a new idea.
The founders initially developed a central system to connect business data. The technology was promising, but demand remained limited. The arrival of ChatGPT inspired a new approach: combining the language capabilities of large language models with the connected knowledge in the graph. That idea became Flyweight AI.
Early 2025
Flyweight AI goes live.
After around three years of development, Flyweight AI launched in early 2025 as a solution built specifically for Shopify. Its Knowledge Graph makes a brand’s knowledge available to the AI, helping it answer more accurately and understand how things connect. It also provides the foundation for AI agents that handle tasks across the store and connected systems. Since launch, more than 800 brands on Shopify have chosen Flyweight.
How we work with you
Talk directly with an engineer, starting with your demo.
At Flyweight, advice and development go together. From the first call, you can discuss your questions with someone who knows the technology: what’s possible, which integrations you need and how we could put it all together.
Products that need explaining? An ERP integration? A process that takes up too much time? Those are the things we enjoy working on. We listen, ask questions and work out what makes sense for your business.
Your dedicated contact stays with you through setup and ongoing improvements. They know your goals and help turn the plan you agree on into a working solution.
What could we make easier for you?
Show us your brand and tell us what you’re working through. Let’s see where AI could help.
