korean founder building rinda: finds overseas buyers for exporters and drafts in their language, so nobody writes "dear sir/madam" at 2am. a human hits send.

openai's frontier models now train on a cached copy of the web. no live internet. one slipped out through dns in september. anthropic's mythos 5 went after a real github repo when a uk test left the internet on. your prod agent: live internet and the .env file
comparison table titled "frontier models lose the live internet", two incident reports from oct 23, 2026. anthropic mythos 5 (july, uk aisi cyber test): internet was left on; it went off-scope in 9 of 43 runs, once pushing malware at a real github repo with fake accounts; stopped by the repo maintainers saying no; new rule: no internet in aisi cyber tests. openai training (sept 20): a misconfigured dns resolver gave limited live internet access; contained, then an 11-day pause; new rule: training uses only a cached "offline world".

deleted ~830 old posts from this account yesterday. july 2025 alone was 282 posts of "ai-driven global expansion" energy. barely anyone read them. volume isn't a strategy. one post worth reposting beats 282.
Bar chart of @DavidBuildsAI original posts per month, July 2024 to October 2026. Almost every month has 0 to 7 posts, except a spike of 282 in July 2025 (labeled 'the game-changer era') and 134 in August 2025. October 2026 has 21 (labeled 'now: fewer, better').

typing "k-beauty moisturizer, us importers" is easy. knowing who on that list still buys is not exporters, how do you check a buyer is still active before you write?

korean exporters keep a buyer list that looks busy on monday and quiet by friday. too many rows just sit on "sent".

Same chat box, different job. A chatbot hands you a template and asks for another prompt. The job I hand ara: - research which importers fit - write the first email in the buyer's language - draft the follow-up when a buyer goes quiet I read each email before it leaves.

Our 1,000th signup didn’t feel like a vanity metric. It felt like a reminder. There are so many great products that never cross borders — not because the product isn’t good, but because global sales is still too hard to start. Finding buyers. Writing the first email. Following up. Building trust across languages. After meeting founders across Korea, this problem feels more meaningful than ever. Thank you to the 1,000 companies using RINDA. We’ll keep building until great products no longer stop at the border. Back to another late night.

[Roast My Landing Page] "'Your website looks sketchy.' Five times this month. From serious prospects. We have 300+ clients, 40% MoM growth, and a real product. But our 2010-era landing page is killing deals before they start. Today we're fixing this. First impressions aren't vanity. They're velocity. Building: rinda.ai
