Mezmo review and pricing

Observability pipelines plus log search; LogDNA rebrand pivoted toward routing.

By Mezmo, Inc. (formerly LogDNA) · Founded 2015 · Mountain View, CA · private

Mezmo (formerly LogDNA, rebranded in 2022) raised an $80M Series D in 2021 and has pivoted from a pure log search product toward observability pipelines: ingest control, masking, reduction, routing, and destination management before logs land in any storage. The repositioning is genuinely useful for buyers wrestling with Datadog log bills, because Mezmo can sit upstream and reduce volume by 40-70% with field-level controls before the expensive ingest fee starts. The trade-offs are that the original log search product has received less roadmap attention since the rebrand, the documentation reflects two product eras, and the integrated UX is less polished than it was at the LogDNA peak.
