​The Revenue Engine Hackathon: Paris Edition 🇫🇷

​October 27th • Morning Panoramas - 36 rue Vivienne, 75002 Paris • 30 Slots Available

​Build your Revenue Engine in 1 day.

​Most startups spend months building their GTM setup. You’ll build yours in a single day.

​Join our hands-on GTM hackathon for early-stage startups to design, build, and launch a scalable revenue engine from the ground up.

Exclusive for HubSpot for Startup members. Join here!

​What to expect?

​✓ An application-only cohort
Join 30 high-potential startups, which will be selected based on stage, growth plans and GTM challenges. VC-Backed Startups. Over $2M in funding with a sales team already in place and growing.

​✓ A Revenue Engine built for your business
Work on what your team will actually use tomorrow—using your data, your ICP, your team, and your processes. This is not a shared demo.

​✓ GTM experts in your corner
Get hands-on support from GTM and product experts at HubSpot, lemlist, and OpenAI throughout the entire build day.
In partnership with Make the Grade, Kano Group & Kokoro AI.

​What you'll build

​In one day, you’ll launch a working GTM engine — and leave equipped with the tools you need to manage and evolve it for years to come.

​CRM & Revenue Ops — HubSpot
CRM setup, pipeline architecture, revenue operations and reporting dashboards — built on your data, not a sandbox.

​AI Agents & GTM Intelligence — OpenAI
Research agents, ICP qualification, lead scoring and custom GPT workflows plugged into your actual go-to-market motion.

​Data Enrichment & Prospecting — Clay
Build a sample of target accounts and contacts from your ICP, enriched with verified contact details, buying signals and custom data points uncovered by OpenAI-powered research agents. Work with Clay through Codex/CLI or MCP, then sync your enriched data back to HubSpot.

​Multichannel Outbound — Lemlist
Campaign design, sequencing and personalisation at scale. Your first outbound campaign goes live before you leave the room.
