LinkedIn says don't treat leads as finish in B2B
At LinkedIn's B2Believe event in its new Empire State Building space, executives and practitioners called for a shift from lead-centric B2B marketing to a 'full journey' approach that links signals, targeting, creative, full journey, and measurement. Jae Oh, senior director of product management, revealed that fewer than 10% of upper-funnel audiences make it into bottom-funnel campaigns, urging marketers to connect awareness with demand capture. Research from LinkedIn's B2B Institute with eMarketer showed 77% of marketers say they no longer target individuals, yet only 31% have a playbook for activating audiences down the funnel. Practitioners from Canva, SAP, Mastercard, and others shared examples of aligning marketing and sales on common signals. LinkedIn also outlined a product roadmap focused on cost-per-opportunity targeting, multi-format campaigns, agentic workflows, and incrementality forecasting.
State of Tech Industry 2026: AI Coding Agents Transform Software Engineering
The article, based on a keynote by Gergely Orosz at the LDX3 conference, presents a comprehensive analysis of the tech industry in late 2026. Key trends include the widespread shift to AI coding agents, with most engineers no longer writing code by hand and running 5-10 agents in parallel. Agent-authored PRs on GitHub now exceed human-authored ones, and AI-generated code is leading to a 'golden age' of migrations. The IDE is fading, replaced by CLI-first and agentic environments. Code reviews have become 'theatrical' due to overwhelming volume, and AI-only reviews are rising. Teams are smaller, engineering specializations are blurring, and there is a trend of CTOs resigning to build. Challenges include quality degradation, increased context switching, and infrastructure shortages (GPU, memory, CPU). The article also covers the rise of 'agentic software factories' and custom agent harnesses at major companies, alongside a trend of moving to open AI models to reduce costs.
Treasure AI Launches Personalization Studio, New Pricing Model
Treasure AI announced Personalization Studio, a marketer-facing UI for building and managing real-time website personalization campaigns. The tool leverages the company's unified customer data and real-time decisioning, part of its Agentic Experience Platform (AEP). Personalization Studio aims to reduce marketers' dependence on technical teams by enabling campaign setup in about 10 minutes. The announcement was made at the Agentic World 2026 conference. Concurrently, Treasure AI introduced an engagement-based pricing model for email, tying costs to customer actions such as clicks rather than message volume. This move reflects a broader industry trend among martech vendors adapting pricing to AI-driven capabilities. Chief Product Officer Rafa Flores highlighted the bet on click-through rates, underscoring confidence in the platform's intelligence.
