    From Zero to $1M ARR in 30 Days & Solo. Using Just AI - Ben Broca, Founder of Polsia | Episode #43

    What does it actually take to build a company in 2026? According to Ben Broca, not much more than a laptop, a stack of AI tools, and the willingness to trust the technology further than most founders are comfortable with. Ben is the founder of Polsia, an AI platform that builds and runs companies autonomously. You give it an idea and a team of AI agents handles the product, the marketing, the support, the competitive analysis, and the daily prioritization. All of it. Ben hit $1M ARR in his first month, tripled to $3M ARR within two months, and now has over 3,000 companies running on the platform. He did it without a single full time employee. In this episode, Charlie, Conor, and Mallory sit down with Ben to unpack how he got here, what he learned building under Travis Kalanick at CloudKitchens, and why he believes most founders are dramatically underestimating what AI can already do. What we cover: How Ben built Polsia in two months after nearly a year of building products he was not inspired by The Travis Kalanick lesson on hiring that shaped how Ben runs Polsia today Why Ben used an AI agent to field investor emails and built a live data room as a fundraising stunt How Polsia monetizes with a flat monthly fee plus a 20% revenue share on what companies earn Why Ben thinks AGI is already here and what that means for how builders should be thinking about their teams The moment Claude told him "six days, ship it" and became his most effective co-founder What Polsia looks like in two years and why Ben wants to democratize access to the American dream at scale Also in this episode: Charlie and Conor cover the Matthew Gallagher and Medvi story, the solo founder who built a GLP-1 telehealth company to $401M in revenue in its first year with $20,000 and a stack of AI tools, and what it means for the one person company era that Sam Altman predicted and Dario Amodei said would arrive in 2026. If you are building solo, thinking about building solo, or just trying to understand how far AI has actually come as an operating layer for real businesses, this one is for you.

In this episode, Charlie Hernandez, Conor Douglas, and Mallory Loar sit down with Grace to unpack how she actually builds things: communities, audiences, brands, and a life on her own terms.

    Copy Our AI Marketing Stacks | Episode #43

    No guest this week -- just Charlie, Connor, and Mallory getting into the weeds on the exact tools and workflows powering their agencies, their products, and this podcast. If you're an AI founder or indie hacker trying to figure out how to actually do marketing without a full team, this one's for you. What we cover: Connor's AI Content Flywheel -- Connor built a full content generation system using Claude Code and Railway that ingests your brand guidelines, competitor data, Ahrefs keywords, and voice/tone rules, then produces SEO-optimized blogs, email campaigns, and social posts -- automatically pushing drafts to Webflow and Mailchimp. He walks through how it works, what it took to build, and what's still in progress. Charlie's Claude Cowork + Slack Automation -- Charlie wired up Claude Cowork to a dedicated Slack channel so branded content drops in automatically every morning and afternoon -- complete with sourced images, overlaid pull quotes, and the BGL logo ready to post. He also shares how he's using project-level context to have Claude help build out Campaign Pilots, and why agent orchestration finally "clicked" for him. Mallory's Agency Workflow -- Six months into running her marketing agency and fully booked her calendar, Mallory breaks down how she uses Granola to capture discovery calls, NotebookLM to surface ICP patterns from research, and Claude to generate scopes of work, positioning docs, and launch playbooks -- all while keeping the human touch her clients actually hire her for. The bigger conversation -- Where does AI earn its place in brand, community, and creative work? And where does human judgment still win? This week's AI news: A vibe-coded app (Moltbook) sold to Meta in 42 days -- built without writing a single line of codeOpenAI drops GPT-5.4 with a 1 million token context window, re-entering the agentic coding raceSweden is being called the new Silicon Valhalla -- and Lovable's $400M ARR story is leading the chargeComing up next week: Grace Ling, founder of Design Buddies -- one of the largest design communities in the world with over 100,000 members.

    SEO and Content Marketing in the AI Era with Brendan Hufford | Episode #42

    What does it actually take to grow a SaaS company through content marketing when AI is reshaping search as we know it? In this episode, Charlie sits down with Brendan Hufford, head of marketing at Grow Sprints, to dig into the strategies that actually move the needle and the ones that don't. Brendan's path to marketing is anything but typical. A former teacher turned web designer turned SEO consultant, he now helps SaaS companies escape what he calls "checkbox marketing," the trap of going through the motions without a real strategy behind them. His framework centers on three pillars: discoverability, relationship, and viral loops. The conversation gets into the current state of SEO in an AI-driven world. Brendan is refreshingly direct: organic traffic is down across the board, but the audience that does show up is more targeted than ever. His answer is to stop chasing top-of-funnel volume and start investing in down-funnel content that speaks to people who are actually ready to buy. For early-stage companies wondering where to start, Brendan's advice might surprise you. Skip traditional SEO for now and focus on partnerships and customer-driven content first. He also shares his own marketing tech stack, including how he uses Claude and other AI tools, and why the key to winning with AI is what he calls "winning like stupid," meaning just actually implementing the tools while everyone else debates them. Whether you're building your first content strategy or rethinking an existing one, this episode is packed with practical, honest takes from someone who's been in the trenches.
