AI Agents for Construction Firms: Bids, Safety, Tracking

An AI agent that calls five APIs holds five sets of credentials that an attacker can steal. That's not a hypothetical risk. The 2024 IBM Cost of a Data Breach Report found that stolen or compromised credentials…
AI Agent Performance Tuning: Cut Latency and Token Waste
Your AI agent works. It answers questions, calls tools, returns useful output. But it takes eight seconds to respond, and your token bill keeps climbing. Sound familiar? Performance tuning is the difference between…
AI Agent Cost Attribution: Track Spend by Agent, Task, and Team
Your company runs 15 agents across four departments. The LLM bill arrives as a single line item. Finance asks: "Who spent what?" You don't have an answer. That gap between aggregate spend and per-team accountability…

How to Validate an AI Agent Idea Before You Build
Most builders skip validation. They pick an agent idea on Saturday, build for 40 hours over two weekends, publish to a marketplace, and watch it sit at zero runs. According to CB Insights' 2024 post-mortem analysis…

AI Agent Unit Economics for Builders (2026)
Builders keep asking the same question: is this agent actually worth shipping? Most answers floating around treat AI agents like SaaS products with seat counts and CACs. They are not. An agent is a piece of software…
AI Agent Marketplace Splits Compared (2026)
Most builders look at a marketplace headline split, 70/30, 80/20, 95/5, and stop reading. That's the expensive mistake. The percentage is the smallest variable in the equation. What matters is everything sitting…

Most teams don't need another tool to build an AI agent. They need an agent that already works. According to McKinsey's State of AI 2025 survey, 88% of organizations now report regularly using AI in at least one…
