AthenaHQ

Low Procurement Risk · Strong Fit
Estimated Floor (5 Seats · Starter)From $295 / mo ($3,540 / yr floor)Published base floor: Free plan · $295/mo · Enterprise plan.Fits within $800/mo cap (37% of ceiling at base floor)

Walk-Away Rule: Walk away if you require transparent self-serve monthly billing or your budget ceiling is under $1,000/mo (Petra Labs requires sales-gated custom quoting).

Negotiation Lever: Demand a 30- to 60-day paid pilot opt-out clause in the Petra Labs order form before signing a 12-month enterprise commitment.
