Why MAINLY?

Startup spirit meets big law experience
We are young and agile ourselves – we understand your pace and your pain points. No 9-to-5 thinking, but flexible response to your timelines.

At the same time, we bring experience from renowned big law firms, where we have advised companies of all sizes – from Series A funding rounds to DAX corporations. This combination helps us give you the best advice both legally and economically.
Business-first instead of naysayers
Other lawyers explain to you why something doesn't work. We find ways how it works.
Our goal is to enable your business, not to slow it down. We never lose sight of legal security – but it serves your business success, not the other way around.
Digital natives with tech understanding
We speak your language: APIs, cloud services, AI integration, SaaS models.
We understand the technical fundamentals and can develop legal solutions that fit your tech architecture.
Startup-friendly cost structures
We know what it's like to watch the budget.

That's why we offer flexible pricing models:
- Fixed prices for defined projects
- Budget caps / fixed price ceiling for planning security
- Subscription from small monthly contributions to fixed work quotas as external legal department
Fast response times without corporate overhead
When it's urgent, we're there. For cyber incidents or regulatory inquiries, we respond in hours, not days.

No endless approval loops, no bloated hierarchies.
