Orum review and pricing

AI parallel dialer leader with consistently 4x+ meeting-set rate over single-line dialers.

By Orum · Founded 2019 · San Francisco, CA · private

Orum launched 2019 (founder Jason Dorfman) and closed a $45M Series B Apr 2022 led by Tiger Global. The platform pioneered the modern parallel-dialer category: AI-driven prospect prioritization plus simultaneous calling of 3-8 leads, maximizing meeting-set rate per SDR-hour. Wins on parallel-dialing depth, modern UX, and PLG SDR-team adoption. Loses on enterprise contact-center coverage (parallel dialing is regulated differently in some jurisdictions) and brand mindshare in traditional inside-sales procurement defaults.

Best for

B2B SDR teams (50-2000 SDRs) running outbound prospecting at scale.
