Fiber AI

High Deal-Risk · Constraint Mismatch
Estimated Floor (5 Seats · Growth)$900 / mo ($10,800 / yr on Growth)Stepped to Growth ($900/mo) for 5-seat team capacity (entry tier starts at $300/mo).Exceeds your $800/mo cap by +$100/mo
  • Budget Ceiling Breached ($900/mo vs. $800/mo cap): At 5 seats, Fiber AI's verified entry floor (From $300/mo) exceeds your $800/mo budget before add-ons or overages.
  • Published Self-Serve Entry Floor: Fiber AI publishes a transparent entry point (From $300/mo) for initial validation before committing.
  • Tier Fit for 5-Seat Scale: Growth ($900/mo): For high-growth teams optimizing outreach at scale.
  • Primary Operational Bottleneck: Credit consumption volatility: Automated multi-step agent runs execute cascading API queries that can rapidly exhaust monthly credit allocations during broad exploratory prospecting passes.

Walk-Away Rule: Walk away if your team is at early validation stage with a <$250/mo tool budget (Fiber AI starts at From $300/mo before seat or usage expansion).

Negotiation Lever: Negotiate price-lock protection on additional seats and overage credits above the From $300/mo entry tier.

Firmable

Low Procurement Risk · Strong Fit
Estimated Floor (5 Seats · Teams)$75 / mo ($900 / yr on Teams)Stepped to Teams ($75/mo) for 5-seat team capacity (entry tier starts at $55/mo).Fits within $800/mo cap (9% of ceiling at base floor)
  • Published Self-Serve Entry Floor: Firmable publishes a transparent entry point (From $55/mo) for initial validation before committing.
  • Tier Fit for 5-Seat Scale: Teams ($75/mo): Perfect for small teams looking to scale up their growth
  • Primary Operational Bottleneck: Regional Data Skew: While registry coverage is dense across Australia, Canada, and the United States, coverage degrades significantly in non-English emerging markets where public corporate filings lack standardized machine-readable interfaces.

Walk-Away Rule: Walk away if your workflow requires uncapped enterprise volume on the From $55/mo entry plan without upgrading tiers.

Negotiation Lever: Validate exact quota thresholds (seats, credits, or API calls) included in Firmable's From $55/mo tier before converting from monthly to annual billing.
