Airscale
Stands out: Unused credits roll over while you stay subscribed, with unlimited users, an MCP server, and a public API.
Watch out: Airscale has no native contact database; credits pay for lookups across partner providers. A verified email costs 2 credits, and mobiles cost more.
Not the right fit for
- Buyers who want one native contact graph, not a marketplace
- Desks that will not watch per-provider credit costs
Bitscale
Stands out: A spreadsheet-style workspace with waterfalls, signals and AI agents, and credits spent only on valid provider results.
Watch out: The jump from Free to Growth at $349/mo is steep. Salesforce sync starts on Booster, and SSO and Snowflake pipelines are Enterprise.
Not the right fit for
- Solo SDRs who need a cheap email finder
- Teams that only need email verification
