The AI-powered live conversation platform that deletes the busywork of outbound calling - so sales reps spend their day talking to humans, not voicemail.
The best-performing channel in B2B sales is still a phone call. The worst part of a sales rep's day is making them. Somewhere in that contradiction sits Orum, an Austin-based software company that has spent years engineering away the dead air between dials.
Orum builds an AI-powered live conversation platform. At its core is a dialer that does the tedious work a human rep would otherwise grind through: it dials numbers, listens for what happens, and filters out the voicemails, dead lines, invalid numbers, and automated phone trees. Only when a real person says "hello" does it connect the rep. The rep, in other words, gets handed the one thing that matters - a live human - and skips everything else.
The company frames its own value in almost philosophical terms. "We built Orum at the moment a human conversation begins," founder Jason Dorfman has said. "That's where the signal is." Everything before that moment is noise the software is designed to absorb.
Around the dialer, Orum has assembled a broader stack: a virtual "salesfloor" that recreates the buzz of an in-office bullpen for remote teams, live call listening for managers, and - since 2025 - a full AI coaching and enablement suite. The pitch has grown from "dial faster" to "get an entire revenue team better at the job."

Orum sells to the people who live on the phone: sales development reps, account executives, and the revenue leaders who manage them. Named customers include Workato and QTS, and more than 1,200 revenue teams run on the platform - from startups to enterprises.
Legacy auto-dialers were slow, expensive, and clunky. A rep could burn an hour punching in numbers and sitting through ringing just to reach a single live conversation. The channel worked; the workflow didn't.
Orum's AI detects live answers versus voicemails, navigates phone trees, and skips bad numbers - dialing multiple lines at once. Reps report connect-rate lifts of up to 400% and far more conversations per hour.
New SDRs take months to get productive. Orum's coaching suite - scorecards, live visibility, AI roleplay - is built to shrink that window and make coaching continuous rather than occasional.
Distributed teams lost the buzz of a physical salesfloor. Orum's virtual salesfloor lets reps dial side by side and lets managers listen in live, rebuilding team momentum online.
A platform that starts at the dial and now stretches across the whole revenue org.
The flagship. Automates outbound calling - human-vs-voicemail detection, phone-tree navigation, bad-number filtering, and multi-line dialing - so reps only connect on live answers.
A virtual sales floor that recreates in-office energy for remote teams, with live call listening and monitoring so managers can coach in the moment.
AI Scorecards grade every call automatically, AI Notes capture context, live visibility surfaces meetings, and AI roleplay lets reps practice against real customer scenarios.
Native connections to Salesforce, HubSpot, Outreach, Salesloft, Apollo, Gong, and ZoomInfo - logging activity, syncing data, and surfacing contact context on every call.
The AI dialer category has gotten crowded - Nooks, Koncert, PhoneBurner, Kixie, PowerDialer.ai and legacy auto-dialers all compete for the same reps. Orum's most durable edge isn't a single feature; it's the data underneath. Its AI is trained on more than a billion real sales calls, an asset newer, AI-native rivals are still working to accumulate.
The philosophical difference matters too. Where much of sales AI aims to replace the rep, Orum's stated bet is to augment the human - clear the noise, surface the person, then get out of the way. "AI should do more than assist from the sidelines," Dorfman argues. "It should enable, empower, and evolve with your team."
Orum runs a classic B2B SaaS model: seat-based software sold to sales development, inside sales, and revenue teams. Buyers pay for outcomes they can measure - higher connect rates, more meetings booked, and shorter ramp time for new reps. Third-party estimates put annual revenue around $36M.
The company sits inside the broader sales engagement and revenue-technology market, adjacent to sequencing tools like Outreach and Salesloft and conversation-intelligence platforms like Gong. Rather than compete head-on with all of them, Orum integrates - positioning the dialer and coaching layer as the live-conversation engine on top of the existing stack.
Its expertise is narrow and deep: the physics of a phone call. Detecting a human in the first half-second, deciding how many lines to dial, routing the connection instantly, and mining the resulting audio for coaching signal. That focus - and the billion-call dataset it produced - is the foundation everything else is built on.
Founder-market fit runs through the whole story. Jason Dorfman was the first sales hire at data-management company Rubrik, where he built the SDR, inside sales, and corporate sales organizations. Orum began as the tool he wished he'd had - a side project that was generating real revenue before it ever raised outside money.
More than $50M raised, with a Series B that reportedly valued the company at roughly triple its prior round.
| Round | Amount | Date | Lead / Investors |
|---|---|---|---|
| Seed | ~$8M | 2020 | Unusual Ventures |
| Series A | $25M | Aug 2021 | Craft Ventures, Unusual Ventures |
| Series B | $22M | Nov 2022 | Tribe Capital, Craft Ventures, Unusual Ventures |

Dorfman was Rubrik's first sales hire and built its SDR and inside sales orgs before founding Orum.
Orum was generating real ARR as a side project before it ever took outside funding.
