Role-specific agent products have displaced general-purpose systems in professional workflows. Finance led adoption (Dexter at 10K stars; structured data enables clear evaluation), spawning open-source replacements like AutoHedge. Personal agents manage threads and worktrees; tax planning saves $1k–$20K per user; bookkeeping saves 6–8 hours. Glenberry (GTM agent) sources leads, manages CRM in plain Google Sheets, transcribes sales calls, automates follow-ups, and builds dashboards—replacing multi-tool stacks. Vercel's internal agent (@v) operates daily across finance, comms, docs, marketing, and analytics with exponentially growing interactions, demonstrating dogfooding shapes commercial products. Monaco's beta cohort of several hundred hypergrowth startups reported average +16 percentage point month-over-month revenue growth increase (vendor-reported, unverified) and tripled average monthly meeting volume. Cross-tool context ingestion surfaces cross-cutting insights unavailable in siloed platforms. Within a year, GTM teams will shift from manual tool-switching to agent-orchestrated workflows, positioning AI-driven sales tooling as competitive differentiator.
