When it comes to salary it's low and increment is negligible - Mitarbeiter (anonym) bei Codebox: Mitarbeiterbewertung

Salaries that the company offers are reminiscent of the skill sets an individual possesses. There are no upper limits to the salary you can get at Codebox and we have been very generous with salary hikes with employees who have exhibited the capability and the skills to command that salary. With that being said, I fail to understand why you accepted the salary offer and joined Codebox though the salary was less ?
