​The Revenue Engine Hackathon: Madrid Edition 🇪🇸

​November 5th • Venue in central Madrid, announced shortly • 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 Startups members. Join here!

​What to expect?

​✓ An application-only cohort
Join 30 high-potential startups, selected based on stage, growth plans and GTM challenges. VC-backed startups in the Madrid area, pre-Series B, with over $1M in funding and 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 and lemlist throughout the entire build day.

​✓ An engine you keep
You leave with a working setup running on your own data, not a slide deck.

​What you'll build

​In one day, you’ll launch a working GTM engine, and be 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—on your data, not a sandbox.

​Data Enrichment & List Building with Clay
ICP definition, account and contact sourcing, waterfall enrichment and signal tracking. You'll leave with a qualified target list built from your real ICP.

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

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