Attio

Low Procurement Risk · Strong Fit

Estimated Floor (5 Seats · Entry / Starter)$220 / mo ($2,640 / yr floor)Exact seat math: 5 seats × $44/seat/mo on Entry / Starter ($44–$99/seat/mo). Upgrading to Growth / Professional ($99/seat/mo) equals $495/mo ($5,940/yr).Fits within $800/mo cap (28% of ceiling at base floor)

Linear Per-Seat Scaling (5 Seats × $44/seat/mo): Base license scales linearly with operator headcount ($220/mo for 5 seats on Entry / Starter).
Primary Operational Bottleneck: API Ingestion Limits: High-volume external API syncing faces throughput throttling during bulk backfills, delaying historical message indexing across substantial legacy inboxes.
