Shaun Thresher built his own AI powered second brain, using Claude Code, to run his marketing and copywriting work end to end. In this episode, Shaun walks through how he moved from bouncing between two separate AI chat windows to a single centralised system that reads his voice, his clients' details and his workflows before it writes a word.
He explains why one well briefed agent with multiple skills beats a pile of specialised agents, how he trains AI to score new content against his best performing posts so it stops sounding repetitive, and how he uses AI to dig up prospect lists most competitors never find, including one built from a public FDA compliance database. Whether you're just starting to explore Claude or ChatGPT, or you're ready to build a proper system around your marketing operation, this conversation is full of practical, hard won lessons.
Guest Introduction
Shaun Thresher is a copywriter turned AI systems builder who spent eight years at Agora Financial, a top US direct-response shop, before becoming CMO of online assets at a publicly-traded company and later CEO of one of its e-commerce brands. He now runs BioRevGrowth, building AI powered "second brain" systems for marketers, and since January 2025 has led marketing and technical operations for a US-based long COVID doctor.
Key Topics
- Moving from copying and pasting between ChatGPT and Claude to a single centralised second brain, built and stored in GitHub
- The difference between agents, skills and workflows, and why Shaun now favours one well briefed content agent with multiple skills over many separate agents
- How Shaun sources prospect lists from public databases, including an FDA compliance database, instead of relying solely on paid tools like Clay
- Building a "digital fingerprint" from a client's best performing content so AI generated posts match their voice and tone
- Scoring new content against a curated pool of top performing past content to avoid repetitive, generic AI output ("AI slop")
- Why Claude Code offers more flexibility than a standard chat interface, including API and MCP connections into tools like Google Ads and Meta Ads
- Common pitfalls: memory systems that quietly stop working, and installing unfamiliar agents without understanding how they operate
- Advice for marketers starting out: pick one problem to solve, invest in a higher tier AI plan, and find a community for support

APAC's B2B Growth Podcast
APAC's B2B Growth Podcast (formerly Growth Colony) is a bi-weekly interview show unpacking trends, busting myths and delivering insights B2B marketing and sales leaders across Asia-Pacific can put to work today.
Each episode, host Shahin Hoda sits down with a marketing leader, sales leader, founder or operator who has a real point of view, not a generic take.
Guests bring specific stories from inside their own companies: what worked, what failed and what they'd do differently.
We cover what's actually driving B2B growth in the region: account-based marketing built for APAC rather than adapted from a US or UK playbook, sales and marketing alignment, and founder and operator commentary from people doing the work, not just talking about it.
If you're a B2B marketing or sales leader in Australia, New Zealand, Singapore or anywhere else in Asia-Pacific trying to build pipeline from strategic accounts, this show is for you.
Hosted by Shahin Hoda, founder of xGrowth. xGrowth is an account-based marketing and go-to-market agency helping global B2B technology companies improve customer acquisition, build qualified pipeline and win strategic accounts across APAC.
The agency works with regional sales and marketing teams to identify priority accounts, develop coordinated campaigns and turn commercial opportunities into measurable growth.
