Descript

There is a certain kind of product insight that, once you hear it, makes you wonder how the entire industry missed it for so long. Andrew Mason had his while building Detour — an audio tour app that Bose eventually acquired in 2017. He was constantly working with spoken audio, constantly fighting audio editing tools built for music producers, constantly frustrated that fixing a mistake in a recording meant hunting for the exact waveform instead of just... fixing the words.

The insight: audio is just a transcript with sound attached. Edit the transcript, and the audio edits itself. He built Descript around that idea in 2017. Video followed. Underlord — Descript's AI co-editor — followed that. And then, in mid-2025, Andrew stepped back to Executive Chairman, handed the CEO seat to Laura Burkhauser, and watched the company he'd built hit $55M ARR growing 75% year-over-year.

How the Editing Actually Works

Import any video or audio into Descript and you get three things immediately: a transcript, a timeline, and a canvas. From that point, the product inverts every assumption traditional editing makes.

• Delete words from the transcript → those words disappear from the video
• Highlight a sentence and hit "remove filler words" → every "um," "uh," and repeated phrase across the entire recording vanishes in seconds
• Don't like how you look? Eye Contact corrects your gaze to face the camera directly even if you were reading from a script
• Bad room acoustics? Studio Sound applies broadcast-quality noise removal with one click
• Flubbed a line after recording? Regenerate rewrites the audio in your own voice cloned voice without re-recording

These are not features bolted onto a conventional timeline editor. They are what Descript is built around. The conventional editing tools — razor cuts, waveform manipulation, J-cuts — are available, but nobody who uses Descript regularly reaches for them first.

Underlord: The AI Director in the Room

Underlord is Descript's AI co-editor, and it is ambitious in a way that most editing tools are not. It doesn't just help you clean up a recording — it helps you figure out what the recording should be. Give it a 90-minute interview, and Underlord can identify the best 10 minutes, write a YouTube description, generate timestamped chapters, create three social clips with captions, and draft a show notes blog post. All before you've made a single manual cut.

The September 2025 relaunch restructured Underlord around an AI credits model — a single pool that covers every AI action, from a Studio Sound enhancement (10 credits/use) to a full video translation with dubbing (15 credits/minute). The goal: replace 17 different feature-specific limits with one flexible budget. The Creator plan's 800 monthly credits handles most weekly creators without hitting the ceiling. Top-up packs let power users buy more credits without upgrading their entire plan.

Descript Rooms: Remote Recording Done Right

In 2023, Descript acquired SquadCast — the remote recording platform used by professional podcasters for its separate audio/video track recording and studio-quality output. That technology became Descript Rooms: a remote recording studio built directly into Descript that records each participant on separate tracks, up to 4K resolution, with local recording that uploads in the background so dropped connections don't ruin the session. The result is a single tool that covers the entire production workflow: schedule and record → transcribe and edit → enhance and package → publish and distribute.

The Business Reality

$55M ARR. 75% year-over-year growth accelerating. $101M raised with OpenAI leading the $50M Series C at a $550M valuation — alongside a16z, Spark Capital (whose GP Nabeel Hyatt has been a Descript board member and champion since the earliest rounds), and Redpoint Ventures. Individual investors include Casey Neistat, Tobi Lütke (Shopify), Naval Ravikant, Shishir Mehrotra (Coda/Superhuman), Lenny Rachitsky, and Rahul Vohra (Superhuman) — a roster that reads like a who's-who of people who understand what it means to build a product that makes creators genuinely better at their craft.
