- Write outreach messages that actually get replies, meetings, and deals.
- Eventually, build and lead your own lead gen team.

- 5+ years of B2B lead gen experience (ideally in Web3, SaaS, AI, or digital product agencies).
- Confident written English (B2+).
- Real experience on Upwork — show us what worked!

- Proactive mindset. You don’t wait for tasks — you move first.
Bonus points if:
- You’ve built or used a personal lead gen system.
- You’ve worked at an agency or studio and understand how they sell.
- You’ve used tools like Apollo, LinkedIn helper, Zapier, Notion CRM, etc.
- You’re curious about Web3, crypto, AI — even if you’re not an expert yet.

- Fully remote setup with flexible hours.
- Competitive fixed salary + KPI bonus + % from deals.
- Work on cutting-edge projects with global clients (mostly from the US, Canada, EU).
- Work closely with the CEO and C-Level team
