RECAP: Builder Sessions: HubSpot Edition - Sales Teams Building Custom Tools
Yesterdary, we hosted another Builder Sessions livestream—this time featuring the HubSpot Connector and some incredible demos from real builders in the Replit community.
If you missed it, here’s everything you need.
What We Covered
The theme of the stream was simple: everybody is a builder now—including salespeople.
We opened with a conversation about how AI has democratized software development, then dove into three live demos from people actually using the HubSpot Connector in their work.
Featured Guests & Demos
Brandon Smith - Director of Revenue Operations & AI Strategy at QuotaPath
Brandon showed off his Mock Deal Data Generator, a tool that creates realistic HubSpot demo environments in minutes. Instead of spending hours manually entering fake data for testing and training, his team can now spin up complete demo environments with one click.

Andrew Verrilli - GTM Team at Replit
Andrew demoed CSV Octopus, his custom data enrichment tool that replaces enterprise solutions costing $50K+/year. It pulls contacts from HubSpot, enriches them via the Apollo API, and syncs everything back—all with a custom UI that fits his exact workflow.
Jacob Fernow - SDR Team Lead at Replit
Jacob built an AI Sales Training Simulator in under 2 hours. It lets SDRs practice cold calls and discovery calls with AI-powered buyer personas. The best part? It gives real-time feedback and scores their performance.
Community Highlights
One of the best parts of this stream was seeing what the community is building. Some standout stories from the chat:
J E shared that they canceled a $60K/year enterprise software subscription and replaced it with a custom tool built on Replit. It’s been running in production for over 6 months.
James Walsh runs a finance company and has built “a full staff platform that each department now runs on.” His AI Training Call Simulator helps new hires practice real scenarios before touching live leads.
The chat was buzzing with people sharing what they’re building, asking technical questions about multi-tenant architecture, and helping each other solve problems in real-time.
