Chert vs Gravitas.io: TCO & constraint stress test
Test how both tools behave under your team size, monthly budget ceiling, CRM ecosystem, and governance guardrails.
Chert
High Deal-Risk · Constraint Mismatch- Opaque Enterprise Quoting vs. SMB/Mid-Market Budget: Chert 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: Commercial pricing is available on request through tailored enterprise sales quotes based on organizational scale and seats.
- Primary Operational Bottleneck: Ecosystem Platform Lock-In: Delivery is fundamentally constrained to recipients active on Apple devices, necessitating separate fallbacks for Android-based enterprise contacts.
Walk-Away Rule: Walk away if you require transparent self-serve monthly billing or your budget ceiling is under $1,000/mo (Chert requires sales-gated custom quoting).
Negotiation Lever: Demand a 30- to 60-day paid pilot opt-out clause in the Chert order form before signing a 12-month enterprise commitment.

- Sales-Gated Contract Terms: Gravitas.io operates under a tailored enterprise procurement model without publicly listed baseline tiers. Commercial pricing is available on request through tailored enterprise sales quotes based on organizational scale, outbound volume parameters, and target market complexity.
- Primary Operational Bottleneck: Throughput Scaling Bottlenecks: Because the platform couples programmatic execution with senior-level human oversight for nuanced positioning, outbound cadence volume cannot scale arbitrarily fast like fully headless mass-messaging tools.
