Comparison

AlphaI⁺ vs Kantata

Per-client pricing from $19/mo vs enterprise-grade complexity.

Kantata (formerly Mavenlink) is a powerful enterprise PSA used by large professional services organisations. But with opaque pricing, 10-25 seat minimums, custom contracts typically $25K-$60K/yr, and months-long implementation, it's structurally inaccessible to firms under 50 people. AlphaI+ starts at $19/mo for solo practitioners and stays affordable at every scale.
