Product Positioning & Context

AI Executive Synthesis
A solution to prevent code changes from silently breaking previously agreed-upon decisions, acting as an automated guardrail for team agreements before merge.
Mo addresses a critical operational friction point in software development: the divergence between team decisions made in communication platforms (Slack) and subsequent code implementations in GitHub PRs. By storing approved decisions and flagging conflicts in PR diffs, Mo acts as an automated guardrail, preventing regressions and ensuring adherence to agreed-upon specifications. This directly improves code quality, reduces post-deployment issues, and streamlines QA processes by catching discrepancies pre-merge. For B2B SaaS, this tool enhances developer productivity, reduces technical debt, and strengthens compliance with internal standards, particularly in agencies or larger teams where communication breakdowns can lead to costly errors. It automates a crucial aspect of governance in agile development workflows.
Built this after a recurring frustration at our agency: the team would agree on something in Slack ("only admins can export users"), someone would open a PR two weeks later that quietly broke it, and nobody caught it until QA or after deploy.Mo watches a Slack channel for decisions. When someone tags @mo to approve something, it stores it. When a PR opens, Mo checks the diff against the approved decisions and flags conflicts before merge.It doesn't review code quality. It only cares whether the code matches what the team actually agreed to.Would love feedback, especially from anyone who's been burned by this exact problem.Try it here: https://hey-mo.io

I was looking for something kind of like this. We wanted to gate release PRs on approval from people in the company that don’t use GitHub.
