When to choose Gravitas.io vs Hotelblock AI (and when to walk away)

Gravitas.io
High Deal-Risk · Constraint Mismatch- Opaque Enterprise Quoting vs. SMB/Mid-Market Budget: Gravitas.io does not disclose a public self-serve floor (Custom / enterprise pricing). Buyers with a $800/mo cap face high sales-qualification friction.
