Krisp snags $5M A round as demand grows for its voice-isolating algorithm – TechCrunch


Krisp’s smart noise suppression tech, which silences ambient sounds and isolates your voice for calls, arrived just in time. The company got out in front of the global shift to virtual presence, turning early niche traction into real customers and attracting a shiny new $5 million Series A funding round to expand and diversify its timely offering.

We first met Krisp back in 2018 when it emerged from UC Berkeley’s Skydeck accelerator. The company was an early one in the big surge of AI startups, but with a straightforward use case and obviously effective tech it was hard to be skeptical about.

Krisp applies a machine learning system to audio in real time that has been trained on what is and isn’t the human voice. What isn’t a voice gets carefully removed even during speech, and what remains sounds clearer. That’s pretty much it! There’s very little latency (15 milliseconds is the claim) and a modest computational overhead, meaning it can work on practically any device, especially ones with AI acceleration units like most modern smartphones.

The company began by offering its standalone software for free, with a paid tier that removed time limits. It also shipped integrated into popular social chat app Discord. But the real business is, unsurprisingly, in enterprise.

“Early on our revenue was all pro, but in December we started onboarding enterprises. COVID has really accelerated that plan,” explained Davit Baghdasaryan, co-founder and CEO of Krisp. “In March, our biggest customer was a large tech company with 2,000 employees — and they bought 2,000 licenses, because everyone is remote. Gradually enterprise is taking over, because we’re signing up banks, call centers and so on. But we think Krisp will still be consumer-first, because everyone needs that, right?”

Now even more large companies have signed on, including one call center with some 40,000 employees. Baghdasaryan says the company went from 0 to 600 paying enterprises, and $0 to $4 million annual recurring revenue, in a single year, which probably makes the investment — by Storm Ventures, Sierra Ventures, TechNexus and Hive Ventures — look like a pretty safe one.

It’s a big win for the Krisp team, which is split between the U.S. and Armenia, where the company was founded, and a validation of a global approach to staffing — world-class talent isn’t just to be found in California, New York, Berlin and other tech centers, but in smaller countries that don’t have the benefit of local hype and investment infrastructure.

Funding is another story, of course, but having raised money the company is now working to expand its products and team. Krisp’s next move is essentially to monitor and present the metadata of conversation.

“The next iteration will tell you not just about noise, but give you real time feedback on how you are performing as a speaker,” Baghdasaryan explained. Not in the toastmasters sense, exactly, but haven’t you ever wondered about how much you actually spoke during some call, or whether you interrupted or were interrupted by others, and so on?

“Speaking is a skill that people can improve. Think Grammar.ly for voice and video,” Baghdasaryan ventured. “It’s going to be subtle about how it gives that feedback to you. When someone is speaking they may not necessarily want to see that. But over time we’ll analyze what you say, give you hints about vocabulary, how to improve your speaking abilities.”

Since architecturally Krisp is privy to all audio going in and out, it can fairly easily collect this data. But don’t worry — like the company’s other products, this will be entirely private and on-device. No cloud required.

“We’re very opinionated here: Ours is a company that never sends data to its servers,” said Baghdasaryan. “We’re never exposed to it. We take extra steps to create and optimize our tech so the audio never leaves the device.”

That should be reassuring for privacy wonks who are suspicious of sending all their conversations through a third party to  be analyzed. But after all, the type of advice Krisp is considering can be done without really “understanding” what is said, which also limits its scope. It won’t be coaching you into a modern Cicero, but it might help you speak more consistently or let you know when you’re taking up too much time.

For the immediate future, though, Krisp is still focused on improving its noise-suppression software, which you can download for free here.
