Brandon Charleson

Brandon Charleson built Instantly's official n8n integration, MCP server, and CLI. He's also one of the hosts of Instantly's YouTube channel, and the founder of Top of Funnel.

Top of Funnel builds and runs cold outbound systems end to end. It starts with deliverability: domains, mailbox provisioning, DNS and SPF/DKIM/DMARC, warmup, inbox placement testing, and continuous monitoring. Inbox placement decides whether anything above it works. Then the data layer: multi-source scraping, waterfall enrichment across providers, ICP scoring, and buying-signal detection that identifies which accounts are actually in market. Then execution: Instantly campaigns wired into n8n workflows and custom AI agents that run the loop without a human babysitting it.

The part most outbound agencies can't do is the layer underneath. Top of Funnel builds enterprise agentic systems: production AI agents, MCP servers, custom CRMs, and the data infrastructure they run on. All of it deploys inside the client's own environment. You own the domains, the inboxes, the database, and the agents. Nothing gets rented back to you.

That work spans small business through mid-market and enterprise, across industries, and into the public sector, including engineering delivery for the United States Air Force under federal data-handling constraints. Brandon was recognized by Forbes in its Top 100 in 2023. Top of Funnel is veteran-owned and certified across Instantly, Clay, n8n, and HeyReach.

Recent results: a seven-day Instantly campaign that sent 16,000 emails at a 2.9% reply rate and produced 86 qualified opportunities. An enterprise n8n deployment running 3,692 production executions at a 0.7% failure rate, saving 61 hours of manual work in a single week.

Brandon teaches this work publicly. On Instantly's YouTube channel he hosts walkthroughs on cold email infrastructure, AI agents, MCP servers, n8n, and lead generation at scale. On his own channel, @brandoncharleson, he's published more than 100 tutorials on enrichment and outbound automation.

Top of Funnel works with B2B teams ready to run outbound as a system rather than a campaign. If that's you, the booking link goes directly to Brandon.
