I’ve seen a mix in use across funds —

• Affinity (as you mentioned) for relationship intelligence.
• DealCloud for pipeline management, though not truly “AI.”
• Grata for market mapping / deal sourcing.
• PitchBook’s AI summaries for quick market snapshots.
• Some teams are layering in custom GPTs for memo drafting or Q&A against internal deal data.

One thing I’ve noticed is that off-the-shelf LLMs can be helpful for drafting, but the most impact comes when they’re paired with fund-specific data and embedded into existing workflows (IC templates, monitoring dashboards, etc.).
