Ora Computing Raises €3.5M for AI Model Compression
Austrian startup Ora Computing has raised €3.5 million in a seed round led by Constructor Capital and Greencode Ventures, with XISTA Science Ventures remaining as a founding investor. Ora develops software that compresses and optimizes AI foundation models, targeting high inference costs and oversize models for edge deployments. According to the company, its approach shrinks models by up to 80 percent and speeds them up by a factor of four, with accuracy loss between zero and five percent. The founders, Stefan Sack and Raimel Medina, are quantum computing researchers from ISTA. Ora left stealth in late 2025 and has validated its solution with automotive and edge-silicon players. The fresh capital will go toward team growth, expanding compression capabilities to frontier models, and launching a commercial product for cloud inference providers and edge AI deployments.
Seed funding for AI model compression addresses inference cost challenges in the AI infrastructure space, but has limited direct impact on the AdTech/MarTech ecosystem at this stage.

OpenAI Expert: Optimize Token Efficiency for AI Agents
In an interview with t3n, Maximilian Hudlberger, Applied AI Engineer at OpenAI, explains that despite decreasing token prices, companies' AI costs can rise significantly, especially with the increasing use of AI agents. He argues that the true measure of cost-effectiveness is not the price per token, but rather the number of tasks completed with a given budget. Unnecessary costs often arise from using the most powerful model for every task, when simpler models would suffice. Businesses should therefore think in terms of completed tasks and optimize their model selection for economic efficiency. The article highlights that the growing deployment of AI agents in enterprise workflows is driving up token consumption, making cost management a critical business factor.
Microsoft Unveils Hybrid Intelligence, Open-Weight AI, RTX Hardware
Microsoft is repositioning Windows as a platform for 'hybrid intelligence,' enabling AI agents to run locally on PCs or in the cloud. The company announced the general availability of Microsoft Execution Containers (MXC), which sandbox agent execution and control access to files and networks, with support from Codex, GitHub Copilot, OpenClaw, and others. New AI models, including Microsoft's MAI Code 1.1 Flash, Nvidia's Nemotron, and DeepSeek V4 Flash, will run locally on RTX Spark devices, including the Surface Laptop Ultra (available for pre-order at $2,599). Copilot is gaining access to local files and system actions on Copilot+ PCs, rolling out in the coming months. Microsoft is diversifying its AI partnerships beyond OpenAI, building its own models, and aiming to regain trust after past missteps by emphasizing security and on-device processing.
Dan Ives: AI buildout only in 3rd inning, top 5 plays
Veteran technology analyst Dan Ives of Yorkville Ives initiated coverage on nearly 50 tech companies, expressing a 'very bullish' stance on the AI sector. Ives believes the AI buildout is only in the '3rd inning of a 9-inning game' and that investors underestimate the $4 trillion spending wave over the next few years. His top five equity plays are Nvidia, Microsoft, Palantir, Apple, and CrowdStrike. Ives highlights the expansion of agentic AI, which increases the attack surface and drives cybersecurity budgets from 5% to 10% of IT budgets within three years. He also sees demand broadening for AI infrastructure beyond hyperscalers to sovereign AI programs and neoclouds. Lesser-known picks include cloud equipment provider Boost Run and autonomous delivery company Serve Robotics, with significant upside projections.
