I Built a $600K/Year Agency at 22. Then I...

At 22, David Sinclair-Black built his cold email agency to $600K ARR. Then he destroyed it. He went from music producer to running an agency that made its first $100K within months. He turned down an offer to sell it at the end of 2024, and a year later he was trying to get rid of it for scraps. In this episode of Making Plays we break down how he got his first clients, the offer that grew the agency, why he walked away from it, and how his new agency, Built Different, is built on revenue share instead of retainers. He also walks through the cold email and outbound stack he uses right now. 🎓Join Making Plays free (+ David's 3-page play-by-play): https://makingplays.ai/join 📨This episode is sponsored by InboxKit (cold email infrastructure: Google, Outlook & Azure inboxes in one place): https://www.inboxkit.com/ 📬Newsletter: 👤David Sinclair-Black: LinkedIn / YouTube / Instagram Chapters 0:00 Cold open: the offer he should have taken 0:13 Intro: Making Plays × David Sinclair-Black 0:47 Free playbook: David's 3 plays (Making Plays) 1:14 Music producer at 16 3:23 From music marketing to cold email 5:52 The offer that sold to musicians 8:03 Why the first market was too small 9:30 Your first client is easier than you think 11:38 When to kill a business 13:45 Why start another agency 16:24 Sponsor: InboxKit 17:00 How he made his first $100K 19:29 Built Different: revenue share 23:50 Where the money really is 26:03 The tool stack right now 31:09 3 things to grow every day 34:26 Where to find David Music: original score (Making Plays). #coldemail #leadgeneration #b2bsales -- cold email, cold email agency, lead generation, b2b lead generation, outbound, outbound sales, agency owner, lead gen agency, pay per meeting, revenue share, agency growth, how to get clients, first client, cold email tools, getleads, syncgtm, leadmagic, clay, deliverability, warm calling, sales podcast, b2b podcast, making plays, abbas somji, david sinclair-black, built different, entrepreneur podcast, cold email agency cold email B2B lead generation outbound sales lead gen agency pay per meeting revenue share agency agency growth first $100K cold email tools 2026 waterfall enrichment deliverability warm calling Making Plays Abbas Somji David Sinclair-Black Built Different
