Chain Reactions Live #0002: WhatsApp's New CEO, Google's A24 investment, Cursor Acquisition

Chain Reactions is the live marketing talk show from Myosin — built by operators, for operators — breaking down the marketing happening all around you with people who actually run growth.Today, Arnav is joined by the two OGs of the show, Blake and Polina, for a 90-minute run-through of the stories the Silicon Valley echo chamber is losing its mind over, a live tool teardown, a debate, and a game that exposes how many ads you consume without realizing it.What we get into:- Kunal Shah taking the WhatsApp global CEO seat — CRED, UPI, and whether messaging apps actually become the payment layer in markets like India, China, and parts of Europe- SpaceX's IPO, the 5% float, and xAI/Grok acquiring Cursor for $60B in stock — a customer-and-talent grab more than an IDE play- Why local models became the whole conversation overnight: token economics, Anthropic's pricing shift, and what the Fable/Mythos restrictions mean for anyone building on frontier models- Google's $75M move into A24, AI in filmmaking, and the creative-tooling debate (Tron, Toy Story, and the "press a button to make AI disappear" crowd)- Markdown — Polina walks through the content automation system behind her UFC prediction tool: trusted-source scraping, virality scoring, Telegram alerts, and Fal.ai image generation with a human always in the loop- Hot Button — should performance marketing report to the CFO or the CMO? A "cordial" debate that turns into a real argument about attribution, LTV, and who owns the risk- Adaholic — guess the brand and category from the ad clip. Polina runs away with it, seven wins deep.CHAPTERS00:00 Intro — welcome back, Blake & Polina01:16 Watercooler: Kunal Shah → WhatsApp global CEO (CRED, UPI, WeChat-ification)09:32 SpaceX IPO + xAI/Grok acquires Cursor for $60B20:07 The local models moment, token economics & Anthropic pricing30:19 Google's $75M into A24 + AI in film and creative38:08 Markdown: Polina's UFC content automation teardown54:32 Hot Button: should performance marketing report to CFO or CMO?1:11:16 Adaholic: name that ad#ChainReactions #GrowthMarketing #AIMarketing #GTM #PerformanceMarketing #MarketingPodcast #Myosin #MarketingStrategy #LocalModels #VibeMarketing #CMO #SpaceX #Grok #B2BMarketing #MarketingNews #GrowthMarketing #AIMarketing
