Graded B on resilience. In Vannus's assessment it depends on a single upstream model with no disclosed alternative — resilient — owns model IP or routes across providers.
Since implementing Claude Sonnet 3.5 as the default model for their agents, Lindy has achieved 10x customer growth.
Vannus grades Lindy.ai against nine dimensions of trust — data sovereignty, training privacy, compliance posture, operational resilience, exit portability, and more. The heaviest criterion asks whether the tool builds its own AI or resells someone else's model; where the vendor discloses it, the grade cites the vendor's own documentation. No paid placements — scoring is walled off from affiliate revenue. See the methodology →
