A company called Morello has just raised $41 million from index and a 16Z to solve one of a video's biggest problems, and that is not having sound effects, background music, or audio in the background of AI generated video clips. Today on the podcast, we'll be diving into the state of AI video generators and what this company, Morello plans on doing with their $41 million in this seed round that they have just raised, who gave it to them, what the and where the market goes in the future. Before we get into all of that, if you want to try all of the AI models I talk about on the show, make sure to go over to AI box AI. There's over 40 different AI models from OpenAI to Gemini to Claude to Grok to 11 labs, 40 other ones. And instead of paying subscriptions to all of these different companies, you can pay $20 a month and get access to all of it in one place without having to switch tabs, have multiple subscriptions. I hope this saves you a ton of time. You can also compare models side by side. Computer, go check it out at AI Box AI. All right, let's get into the show. This is an interesting company, and I also think that it's an interesting problem. And while I'm not saying that Morello is, you know, going to be completely struggling as a company, they do have a lot of headwinds. So they have just raised $41 million. This is their seed round. It was led by A16Z and Index Ventures, so obviously they're getting a lot of VC funding that's going into it. Earlier this year, this is a company that was based in Berlin, but they just released SFX v1 1. So essentially, this is an AI model that it watches a video, you upload to it, and then it's gonna add synced sound effects to the model. To be honest, I think this is something that's really impressive, but the headwinds we'll be facing are from Google and a lot of other AI labs that are already including sound effects into their videos that are being generated now. This wasn't the case when this company first started out, but today that is the case. So the new money that they've raised, they said it's gonna help them to against Google and other people. They. They've been in stealth mode for a very long time, and when they were in stealth mode, they didn't have a ton of resources. There was a bunch of other companies. Sony, Tencent, they released video to sound effect models. Also Kwei Shu, who is owned by cling AI out of China and 11 labs. They've all released models that do the same thing. And so while Morello is different from them because it's a lot narrower of a focus, a lot of those other companies, they're, they're doing more of like the sound and the audio and, and right now Morel or Morello is just focused on the sound effects. So I saw a demo video where it's like a girl walking in, you know, the snow and you can kind of hear like the wind blowing around her and the crunching of the snow under her feet. And so, and it was, you know, it lined up with her footsteps in the video so you could hear the crunch of the snow as her feet made a step. And to be honest, it was like, this is, this is a great tool. This is a great value add. I see this as being very valuable, but the question is, is this not going to be something that a lot of these other video generators have baked in? Now I think the argument for Morello really succeeding is if AI companies can't figure out how to do that and they use the API of Morello and just plug it straight in if the video companies do that. But I, I tend to think that they are, they're going to get there. According to the CEO, they expect their startup to double or triple their headcount. Right now they have a team of only 10 people. So raising $40 million with a team of 10 is very impressive. Their CEO is CJ Simon Gabriel and they've been working on this out of Berlin. As I mentioned, all of the new hires are going to support their R and D. They also have product and go to market strategies that they're working on. And they've recently published their models on F AI and also replicate and they expect the API usage to drive most of the revenue in the short term. So this isn't something that they're expecting users to go and use a lot of. They're really expecting companies that are interfacing with AI video generators to kind of plug these two things together. And now I will, like I know earlier I said I expect a lot of AI video generating companies do this themselves, but in the meantime, I mean, you have to like, I think I have to give them their flowers in a sense that there are a lot of video generators that don't have sound and video editing platforms I think can make really great use of this. In addition, I think, you know, a lot of people will say that Google is going to basically beat them Because Google can already do this. They have the sound effects and the video combined and in kind of the, the Gemini Google generators, video generators that are out right now. But I think there is a lot of use case if you can imagine built into something like Adobe Premiere where maybe you have, you know, footage that was shot, maybe there just is no sound. Maybe you grabbed copyright free footage off online that didn't have any audio to it and you want to add something after the fact, right? You don't want to go and like kind of regenerate a whole video for the clip that you have. You just want to add sound or change the sound in it. And so I think that there's a lot of, or maybe you know, your microphone is off or your microphone is bad on your camera, whatever. I think there's a lot of cases where you have footage and you want to add, you want to add audio to it. And so I think it's probably less of like a creator by creator using their platform for it explicitly. But I think they're right the API usage. So having their software plugged into other software will be a good solution for this. They said that they're investing in building out their workspace for creators. They have something called the Morello Studio which is going to eventually support kind of like a full professional use software studio. So I think this is interesting. I also think plugging it into other products is a really good way to go. So as they're preparing to scale right now, they're also anticipating concerns around training data that have been difficult for a lot of other AI generated companies. According to Georgia Stevenson, who led Index's investment into this company, they base their model on public and purchase sound libraries and their signing revenue sharing partnerships that are giving money back to artists who have rights to some of those, some of those sound effects. So you know, they'll go and they're pay for them and then they're, they have some sort of royalty program. So you know, I think this is a good way to go. It's definitely something that's tricky with a lot of these AI generated tools right now. I think that, you know, people are concerned they're going to displace musicians or sound designers. They currently have a freemium model that has a like and also a 20amonth plan. And so they said that they're mostly targeted amateurs and prosumers that are wanting to unmute their AI generated videos. But I think you could also see a pretty great use case for regular videos getting these sound effects as well. When Their CEO was asked about where they kind of stand in the market. There's a funny quote where he said, George Lucas said that sound is 50% of a movie going experience. It's not an overstatement. If anything, it's an understatement. You can take exactly the same image and the sound will shape a completely, completely different ambiance depending on the sound and the music that you put in there. So he has a co founder as well who's named Florian Wenzel. They're both AI researchers and they're also musicians. So they said that AI music generation is on their roadmap, but I think they are seeing more pull from the sound effects. They obviously are more integrated there. I think part of that is because less researching is happening there than in other fields. And so they, their company stands out. They said, quote, it's easier to build a real moat here and then capitalize on it. So I think this could pay off for Morello. Their valuation has increased very significantly since they did their pre seed round that was led by Atlantic which is based in Berlin as well. They also have some participation and in this new fund that are this new round that was just raised so total they've raised $44 million which is, you know, pretty fantastic for, for the whole company. They are also backed by some angels who give them a bunch of credibility. They have the Mistral CEO which is Arthur Mensch and also the hugging faces chief science officer Thomas Wolf. They also have the foul AI co founder Burke Gur, a bunch of other people. So the team is obviously trying to work quickly. We know that these AI generated videos are not going to probably mute forever and so I think they want to get their technology as advanced as quickly as possible. Google Gemini has their video generator that now incorporates soundtracks which is powered by DeepMind's VO 3.1 audio to our video to audio model. So if anything I think that they know time is of the absence and they're trying to really quickly move on this on this technology.

Host: The Last Invention is AI
This episode delves into Morello, a Berlin-based AI startup that just closed a $41 million seed round led by A16Z and Index Ventures. The company aims to address a major shortfall in today’s AI-generated video: the lack of synchronized sound effects, background music, or audio tracks. The discussion covers Morello's unique approach, its competition, the broader AI video landscape, technical and ethical challenges, and the implications for creators and the future of AI-powered media.
Host, on funding and challenge:
"Raising $40 million with a team of 10 is very impressive." [05:06]
Georgia Stevenson, Index Ventures:
"They base their model on public and purchase sound libraries and their signing revenue sharing partnerships … giving money back to artists who have rights to some of those sound effects." [11:41]
CJ Simon Gabriel, CEO, on sound’s impact:
"You can take exactly the same image and the sound will shape a completely, completely different ambiance depending on the sound and the music." [13:10]
The podcast maintains a conversational and analytical tone, blending accessible explanations with industry insights. The host balances optimism for Morello’s approach with skepticism about long-term defensibility, recurring to the practical realities of the AI startup environment.
Morello’s emergence and sizeable seed round highlight the intensifying race to master the “audio layer” of AI-generated video. With major incumbents building sound into their own tools, Morello’s API approach, creator-focused studio, and artist-friendly licensing could grant them a competitive edge—if they move faster and focus sharper than the tech giants. The episode underscores the growing importance of audio in AI video and hints at the next frontiers in creative AI.
