vibe-coding your CRM is the most tempting bad idea in B2B right now.
we fell for it.
here's what failed after 2 weeks: 👇
a couple weeks ago, Claude built us a custom CRM in a weekend. contact records, pipeline stages, deal tracking — it worked and we felt smart. until we didn't.
3 things we didn't think about:
1/ nobody owns the maintenance. every time something breaks — a routing rule, a sequence trigger, a field mapping — it falls on an engineer. your marketing and sales team can't fix it. it just sits broken until someone with context has time.
2/ it kills your GTM hiring velocity. sales reps and marketers already know HubSpot or Salesforce. onboarding them onto a custom tool nobody's heard of adds friction you really don't need when you're trying to move fast.
3/ your other GTM tools won't play nicely with it. Apollo, Clay, LinkedIn, your email tools — they all have native HubSpot and Salesforce integrations. connecting them to a vibe-coded CRM means more custom work, more maintenance, more things breaking silently.
established CRMs feel like overkill at 2 reps. but the migration you're avoiding now costs 3x more at 10 reps than it does today.
two weeks in, I got tired of sales candidates asking about our homegrown CRM during interviews. so we went back to HubSpot.
hubspot wins again 🤷♂️
