300Brains

A multinational and
multiskilled software house

Perfect communication, dynamic work and a proactive attitude are what we value the most in 300Brains.

We are the opposite of sluggish, centralized IT companies which speak babble to you in the language of robots.
Let’s talk

Our IT Rapid Reaction Forces give you:

Instant feedback and quick
quotation of a project
instead of
“We need more details, please send us the complete documentation of the project”
Short decision-making path
and efficient communication
instead of
„I need to talk to my manager to
give you some feedback.
A wide range
of technologies used
See the scope
instead of
„Let me check if we have sufficient human resources to perform that.”
Agile software
development
See how we work
instead of
“Waterfall methodology based on the linear progression of the project”
Experience in multinational IT
projects for renowned companies
See references
instead of
„Yeah, we used to be a subcontractor in a project for a foreign client.”

Despite several challenges and a very aggressive project schedule, the team worked well together and took extraordinary steps to complete the project on-time. The project team also provided superb hyper-support during the go-live period to minimize as much as possible the impact to our user community for eDealing during the upgrade.We value 300 Brains as a reliable technology and business partner.
