Inside of a $10M+ company that generates leads without cold email or ads! ⬇️ We all use the same methods for lead gen: ❌ Cold emails ❌ LinkedIn DMs ❌ Paid ads This $10M+ company did the opposite. They used Handwritten letters + memes + automation + PAS framework. 🔹 Step 1: Build an intent list using lemlist Clay, PhantomBuster and Evaboot (funding, hiring, news). 🔹 Step 2: Send automated handwritten notes (Handwrytten + Audience.co + Make) 🔹 Step 3: Follow up with a meme using Smartlead & second handwritten note (5-7 days later). 🔹 Step 4: Email sequence using PAS framework (Problem → Agitation → Solution). Email 1: Pattern interrupt Email 2: Pain point + meme Email 3: Solution + workflow They have a closing rate of 60% pretty high than average!

Outbound stack for different maturity stages 👇 LEVEL 1: POC Stage Keep your stack lean and don’t overcomplicate. You don’t have processes and you’re probably the only one selling. Use a lean stack: - Enrich your TAM from 75+ sources (Clay) - Enrich contact info (Fullenrich/Prospeo.io) - Send emails (Smartlead/Instantly.ai) - Leverage warm intros (Sales nav/Referly) → Best suited if you have a big TAM and/or getting started LEVEL 2: Growing Stage Once you start getting traction from 1 or 2 acquisition channel(s), start prioritizing your accounts based on signals rather than industry-based criteria. You can start to : - Streamline your gtm orchestration (Cargo) - Identify website visitors (Koala/Leadfeeder) - Find companies hiring your ICP (Datachimp) - Find similar companies (Ocean.io) - Multichannels campaigns (lemlist) - Prioritize 2-3 signals (Hiring, site visitors, ...) → Best suited for SaaS between 1M to €10M ARR LEVEL 3: Scaling Stage When you’ve created clear sales playbooks and designed systems to scale your sales motion. You can start to: - Track multiple signals (Common Room/Pocus) - Leverage partnerships (introw.io/Crossbeam) - Run person-based ads (Userled/Influ2) - Use Gifts Delivery (Alyce by Sendoso) - Experiment with 2-3 signals per quarter → Best suited for SaaS with an hybrid motion → Or companies with a TAM <10,000 companies
