Kazimi Raises €2.2M to Fight Bots in Mobile Marketing
Berlin-based cybersecurity startup Kazimi has raised €2.2 million in an oversubscribed pre-seed round to scale technology that helps mobile app developers distinguish real users from bots. Market One Capital led the round, with participation from IBB Ventures and mobile/tech executives including Petri Hyökyranta, Janne Peltola, and Erik Massmann. Kazimi uses privacy-preserving cryptographic proofs to verify first-party signals generated inside apps, aiming to improve analytics, marketing measurement, and AI training data while staying compliant with data protection rules. The company cites Cloudflare data showing bot traffic exceeded human traffic in 2026, and AppsFlyer reporting bots remain a major fraud source in mobile channels. Kazimi targets apps relying on paid acquisition, with clients in mobile gaming, rewards, and fintech. The founders previously built security and fraud-detection systems at Adjust before its acquisition by AppLovin. The funding will support scaling and expansion into the global mobile advertising market.
Early-stage funding for bot-detection technology addresses a growing mobile ad fraud challenge, protecting first-party data integrity for analytics and AI, but the round is small and niche.

Meta, Walmart, Sierra launch personal agent protocol
Meta and Sierra, led by chairman Bret Taylor, have announced the Personal Agent Protocol (PAP) for AI-agent interactions with businesses, with initial partners including Walmart, Shopify, Stripe, Genesys, Rocket, and Instinct. PAP defines three access levels (guest, read-only, and write access) built on OAuth and places businesses in charge of vouching for consumer AI agents, differentiating it from rival designs by Visa, Mastercard, and AI platforms. The protocol aims to control customer data and liability in agentic commerce, with future implications for agentic payments. However, PAP is still in early stages: no specification, license, or governing body exists, and payments are not yet supported. Version 0.1 is expected this month, with payments and fine-grained permissions planned later. Notably, Amazon, Google, and OpenAI are absent, reflecting Meta's competitive positioning, especially after Amazon blocked Meta's Muse agent. The protocol competes with OpenAI's Agentic Commerce Protocol and Google's Universal Commerce Protocol.
TypeSafe's Jev Decision Model Explained for Product Managers
The article introduces Jev, a decision model from TypeSafe AI, released in September 2026. Unlike LLMs, Jev returns a decision with a probability based on input text and a question, supporting operations like Noul (yes/no), Choice (one of many options), and Score (rating). It processes up to 32K tokens, with free output tokens and input at $0.042 per million tokens. The author tested it against other models, finding it cost-effective and accurate. Jev is integrated into AskOne for moderation, with rules encoded in prompts to handle abuse and prompt injection. The article notes Cloudflare released similar models (Clef) on October 1, and provides guidance for PMs on quick wins, evaluation, and setup templates.
OpenAI Enhances ChatGPT Ads with Image Formats and Measurement
OpenAI is expanding its ChatGPT advertising offering with a new visual ad format that uses image carousels, initially appearing during image generation. The ads are clearly labeled and separate from content, and the rollout begins in October 2026 for US users and select advertisers, with plans to reach over 60 markets. ChatGPT now surpasses 1.2 billion weekly users, making it the largest AI-based consumer platform. Early results show strong performance, such as WeightWatchers' 15.3% lower cost per acquisition and high new-visitor rates for brands like Dose and Portland Leather. However, a TrafficGuard study reveals that ad clicks are 3.6 times more likely to come from datacenters or proxies compared to Google Ads, with invalid click rates ranging from 0.1% to 34%, indicating early ad fraud challenges. Advertisers are encouraged to verify performance independently.
