The Edge Has Shifted | Matt Reustle on How the Best Investors Use AI
TL;DR
Matt Reustle explains how AI evolved from basic search tools to agentic research assistants capable of automating due diligence and monitoring workflows, allowing investors to leverage technology for junior-level tasks while maintaining human decision-making at the core.
🧠 The AI Inflection: From Toy to Tool 3 insights
Deep research models changed the game
The inflection point arrived in late 2024 and early 2025 with deep research models that function more like agents than traditional LLMs, moving beyond social experiments to professional-grade tools.
LLMs are calculators, agents are analysts
Basic LLMs operate like interns performing single Google searches, while agentic workflows use reasoning to deliver multi-step analysis resembling junior analyst output rather than intern-level summaries.
Premium tiers unlock reasoning capabilities
Free-tier models provide surface-level answers, but premium agentic tiers understand context and deliver synthesized research that investors can actually use for professional decisions.
⚡ Agentic Workflows: Practical Applications 3 insights
Automated cross-sector monitoring
Investors can set up recurring monitors to track specific commentary across unrelated sectors, such as logistics mentions in CPG earnings calls, delivering synthesized alerts without manual transcript review.
Instant due diligence acceleration
Deep research capabilities eliminate the need for outdated sellside primers by generating comprehensive company summaries and thematic research almost instantly.
KPI tracking and position monitoring
Systems can automate quarterly recaps of key data points across entire portfolios, replacing the manual work of earnings-season transcript reviews previously done late into the night.
🚀 Implementation Strategy 3 insights
Journal your process first
Before adopting tools, document your current research workflow to identify specific friction points where AI can provide immediate leverage rather than applying generic solutions.
Progressive adoption path
Start with premium LLM tiers for communication and basic research, then graduate to specialized investment-specific tools for monitoring and thematic screening.
Compliance remains critical
While scraping capabilities exist, investors must navigate legal restrictions and API requirements when setting up automated data collection systems.
Bottom Line
Treat AI as a leverage tool that handles junior-level research and monitoring tasks, freeing you to focus on high-conviction decision-making and relationship-building that algorithms cannot replicate.
