The startup company Grit has developed an AI developer assistant named Grit, which simplifies the software maintenance process by automatically analyzing, tracking, and suggesting updates and improvements. This assistant has secured $7 million in funding, and its founder, Morgante Pell, aims to alleviate the burden on developers through automated maintenance. Grit's open beta version is now live, with plans to cover all major programming languages. This tool is suitable for modernizing old codebases and can save significant time for later-stage tech companies and fintech firms.
