Data Source Maintenance
APIs change. Rate limits shift. Job board structures update. FDA endpoints get versioned. The 25+ data source integrations need occasional fixing - maybe 2-3 times per quarter. This is the #1 reason clients shouldn't self-host unless they have engineering capacity.
Filter & ICP Tuning
Company lists change - acquisitions, name changes, new entrants. The 80+ non-ICP exclusion list and 150+ target list need quarterly refreshes. Signal relevance shifts as PM's product strategy evolves.
Model & Prompt Tuning
LLM models update. Prompt strategies that worked last quarter may need adjustment. Research agent quality degrades without periodic prompt refinement. Template improvements as we learn what reps actually use.
Infrastructure Costs
Cloud server (~$50/mo), API keys (Brave Search, OpenRouter/Sonar, FDA, SEC), LLM inference ($2-5/day for automated scans, $0.50-2.00 per deep dive report). Total: $100-250/month for a single client's agent stack.
