Startup Multiply Launches AI-Driven Real-Time Advertising Platform
Multiply, a B2B-focused media agency startup, exited stealth and announced a $9.5 million seed round led by Mayfield with participation from Sorenson Capital and several industry executives. The 13-person company, led by CEO and co-founder Matt Jayson, offers proprietary AI-powered “self-learning” ads that generate multiple creative variations using real-time signals, CRM and sales-call data, and human review. Multiply currently runs campaigns on LinkedIn and Google Ads and plans to expand to Meta, Reddit and chatbot placements; Jayson said the company has been in talks with OpenAI to introduce ads on ChatGPT. The platform continuously tests audience, messaging and creative iterations via autonomous optimization agents while keeping humans in the approval loop.
Seed funding for a small AI-driven agency indicates early-market innovation in dynamic creative and B2B ad personalization, with potential relevance if the product scales or integrates into major channels (e.g., chatbots).

OpenAI Rolls Out Ad Manager, Expands Ads Push
OpenAI has launched an ad manager it began testing in March, currently available to a limited set of advertisers for real-time performance tracking and optimization. The company recently lowered its minimum buy-in for the ads pilot to $50,000 (from roughly $200k–$250k), while reportedly keeping a $60 CPM. Code snippets reviewed by trade outlets suggest OpenAI plans click- and conversion-based campaigns within ChatGPT. OpenAI projects ad revenue could exceed $100 billion by 2030, a target analysts say requires convincing brands to shift large portions of budgets and delivering results that outperform search and social. The newsletter also covers unrelated industry items: a Google-search booking scam involving a third-party reseller, YouTube price increases for Premium tiers, platform and product notes from Intuit and Meta, and several senior hires.
Meta unveils AI ad tools and Creator Marketing Hub
At Cannes Lions Meta announced a suite of AI-driven advertising features for advertisers, agencies and creators. Key updates include a Shared Space to link creative and media workflows (limited test), Brand Memory to keep AI-generated creatives on-brand, an agency integration being tested with WPP Open, and a new Meta Creator Marketing Hub that merges the Creator Marketplace and Partnership Ads Hub while adding Facebook creators to a pool that already includes 5+ million Instagram creators. Meta also expanded automatic language translation and voiceover support in Ads Manager and introduced workflows for creative approval (in test). Meta cited a company analysis of one million campaigns — using a UC Berkeley test framework — claiming a 25% higher ROAS in 2026 versus 2022. Meta Business Agents now support over one million businesses.
OpenAI quietly launches self-serve ads manager
OpenAI has launched a pilot ads manager that gives a small group of advertisers self-serve access to monitor and optimize campaigns in real time. The interface is described as serviceable and similar in layout to Google Ads. OpenAI recently lowered the pilot minimum spend to $50,000 (from roughly $200k–$250k) and is charging a reported $60 CPM; the pilot has been extended beyond its original end date and may be further prolonged. The move complements hires (David Dugan) and partnerships with ad tech firms such as Criteo and Smartly as OpenAI builds its own ad stack. OpenAI has signaled rapid revenue scaling—Reuters reported a $100 million annualized run rate early in the test—and external estimates (The Information) project a large long‑term ad opportunity. OpenAI did not respond to requests for comment.
