Lessons from building in the open: what worked, what didn't, what I'd do differently. They land here first, then in the newsletter.

  • An agentic OS is the layer that lets AI agents work for you across many runs, not one chat: shared context and memory, tools with limited permissions, a schedule, isolation from untrusted input, and a log you can audit. In 2026 the term names three different things: Microsoft's plan for Windows, vendor platforms that coordinate business agents, and setups people build around a coding agent.

  • Generative engine optimization (GEO) software, in the form most tool lists recommend, asks AI assistants your buyers' questions every day and records whether your brand appears in the answers. For a solo business in September 2026, I would choose between three entry plans by the engines you need: HubSpot AEO at $50 a month, Otterly.AI Lite at $29 and Peec AI Starter at $95.

  • GoPerfect is an AI recruiting platform: you describe a role, it searches what it says are 800M+ profiles, scores each candidate from 1 to 5 with written reasons, and sends outreach by email, LinkedIn or SMS. Its plans are quoted on request, require a one-year commitment and are sized for two recruiters or more, so a founder filling one role should compare it with tools that publish their prices.

  • A good New York Instagram caption says what is in the photo, then adds one detail only you noticed. "Brooklyn Bridge at 7 a.m., before the crowds" tells people more than "concrete jungle". Below are 30 captions sorted by the kind of photo you took, ready to copy. After them come the three checks before you post: first line, place name, five hashtags at most.

  • An AI marketing newsletter is a recurring email that explains what changed in AI and how to use it in marketing work. For a solo marketer in September 2026, four deserve a trial: This Week in AI for weekly news, Almost Timely for long how-to essays, Growth Memo for AI search, and The AI Marketing Newsletter for daily news. Start with two: one for news, one for method.

  • An AI marketing agency is a marketing firm that builds its offer around AI, as the tool it works with or the channel it targets. The label covers three different purchases: done-for-you marketing where AI speeds up the staff, automations built to keep running in your accounts, and work to get your business cited in ChatGPT or Google's AI answers. Ask what you keep if you stop paying to see which one is on offer.

  • ManyChat and Chatfuel both automate Instagram, Facebook and WhatsApp conversations, but they bill for different things. ManyChat charges by Active Contacts, the distinct people who interact in a billing month: 25 free, then paid tiers up to 7,500. Chatfuel charges a flat $20 a month with unlimited contacts and caps AI usage instead. Your comment volume and your channels decide which costs less.

A pivot is often just the polite word we use with investors when the first company is dead and we have decided to build another one. And that is fine. Not because failure is noble, but because luck needs exposure: every market you enter, every product you ship and every channel you test is one more surface where something unexpected can land.
