GoMarble

Low Procurement Risk · Strong Fit

Estimated Floor (5 Seats · Growth / Professional)$139 / mo ($1,668 / yr on Growth / Professional)Stepped to Growth / Professional ($139/mo) for 5-seat team capacity (entry tier starts at $25/mo).Fits within $800/mo cap (17% of ceiling at base floor)

Published Self-Serve Entry Floor: GoMarble publishes a transparent entry point (From $25/mo) for initial validation before committing.
Tier Fit for 5-Seat Scale: Growth / Professional ($139/mo): Verified $139/mo tier from vendor pricing schedule.
Primary Operational Bottleneck: Creative Generation Boundaries: The autonomous agent specializes in budget allocation and performance diagnosis, lacking native asset rendering tools for generating net-new ad copy or visuals.

Walk-Away Rule: Walk away if your workflow requires uncapped enterprise volume on the From $25/mo entry plan without upgrading tiers.

Negotiation Lever: Validate exact quota thresholds (seats, credits, or API calls) included in GoMarble's From $25/mo tier before converting from monthly to annual billing.

Gravity

High Deal-Risk · Constraint Mismatch

Estimated Floor (5 Seats · Enterprise / Custom)Custom Quote (Custom / enterprise pricing)Vendor does not publish a self-serve USD floor on its pricing page; requires sales qualification.Sales-gated pricing vs. $800/mo cap (High quote risk)

Opaque Enterprise Quoting vs. SMB/Mid-Market Budget: Gravity does not disclose a public self-serve floor (Custom / enterprise pricing). Buyers with a $800/mo cap face high sales-qualification friction.
Sales-Gated Contract Terms: Gravity provides custom enterprise licensing structured around organizational scale and user seats.
Primary Operational Bottleneck: Schema Mapping Brittleness: Complex, heavily customized Salesforce or HubSpot object schemas require extensive field-level mapping, creating operational fragility during upstream property changes.

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

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