This is a new segment called Startup Toolkit designed to share tools that can help you to improve many different parts of your business. Some of them are brand new, some existed for a while.

Some of these tools were shared within our internal slack channel for exchanging new tools. Kudos to B24 team for keep finding new ones (especially to the most active Mateusz Czech).
