AI is no longer a party trick. Used well, it does a lot of what elite consultants do: structure ambiguous problems, analyze data fast, pressure‑test options, and turn findings into decisions people can act on. Below is a practical, research‑backed playbook for 2025—centered on the 10 workstreams in the image (SWOT, growth levers, 30‑60‑90, revenue model, churn, KPI blueprint, pricing, GTM, value prop, pivots)—with the prompts, tools, and metrics that make an AI “associate” genuinely valuable. A few facts for context. The latest State of AI research finds generative AI could add $2.6–$4.4T in annual value across functions, with adoption now mainstream among large companies, not just tech firms (McKinsey). 2025 strategy work increasingly […]

Based on the rankings Claude Opus 4.1 consistently outperforms competitors when people test it without knowing which model they’re using. Claude Opus 4.1 is a highly capable AI model across multiple use cases, though it’s worth setting expectations properly – this isn’t a revolutionary breakthrough that changes […]
