Northbridge Strategy produces 20–30 research memos monthly for PE and corporate clients. Associates burned half a day on search, skim, and synthesis before writing.
Pipeline

Research question
→ Planner: 4-8 sub-queries
→ Tavily per sub-query (top 5)
→ Fetch top 3 pages per sub-query
→ Haiku: rank source relevance
→ Sonnet: cited briefing + Limits section
→ Associate verification (required)
→ Notion export
Quality gates
- Minimum 8 unique source URLs
- No claim without inline citation
- Limits section lists uncovered angles
- Partner review before client send

Takeaway
Research automation works when citations are mandatory and humans verify before client delivery. Speed without sources is liability in consulting. Blueprint: workflow guide.
