Pricing breakdown
Iternal
The RFP product (Waypoint, grounded by Blockify) has no published price; it starts with a scoping call and pilot. Other Iternal products publish prices, such as AirgapAI Chat at $697 one-time per seat and AI Academy training at $199/year, but neither is an RFP tool.
Sweetspot
No public pricing: the pricing page routes to a demo booking. At its August 2024 seed round Sweetspot quoted $720/yr for search and $3,600/yr for the full suite, so treat those figures as historical.
