about us

At Solid, we’re building AI video agents — autonomous video creation systems that can analyze, understand, and generate videos that perform.

Video is the dominant language of the internet, yet producing high-performing content remains slow, manual, and expensive. Marketers are sitting on terabytes of footage, but few insights and no scalable way to turn that data into performance. We’re fixing that — by teaching AI to see, hear, and learn what makes a video work.

We’ve already onboarded leading consumer brands like Refurbed, Maniko, Holy Energy, and Dr. Wolff Group. We’re backed by Lucid Capital, Angel Invest, and operators behind Europe’s top creative tech and AI ventures. Our goal: reach €100M ARR with a small, elite engineering core — and make creative performance programmable.

Our founders, **Patrick** and Chris, have spent years building at the intersection of AI, product, and growth. Chris previously led robotics and computer vision systems at Google, while Patrick scaled creative performance operations across top AI apps & SaaS before founding Solid.

But this is not “just” a generative AI company. Building autonomous creative systems means tackling unsolved, frontier problems:

• How do you encode a brand’s visual and narrative DNA into a multimodal model?
• How do you train systems that learn from real-world ad performance at scale?
• How do you generate content that looks human-made — but is entirely AI-orchestrated?
• How do you combine human creativity and machine intelligence into one continuous loop?

These are new challenges — problems that didn’t exist before multimodal AI. There are no playbooks. We’re building the next layer of creative intelligence from first principles.

We’re a small, hybrid team based in Berlin with hubs in Cologne and Vienna, proving that world-class AI companies can be built in Europe 🇪🇺 We believe this decade belongs to teams who combine deep product intuition with technical execution — and we’re here to build one of those companies.

your impact

Help us ship faster by building across product and AI — the workflows, tools, and prototypes that turn real customer pain into reliable product capabilities.

As a Founder Associate, AI / Full-Stack, you’ll work at the intersection of CTO / ML / Engineering: close to core architecture decisions, close to model + agent workflows, and close to the product surfaces customers touch every day.
