With over two decades of experience bridging technology and business, Johan Wadenholt Vrethem focused on harnessing AI to transform how organizations operate and engage with their customers. After leading critical digital initiatives and client engagements in the banking and finance sectors at CGI, Johan co-founded Voxo to drive innovation in conversational analytics and event technology.
Today, through Voxo Insights and Voxo Event, they are delivering real-time, AI-powered understanding of customer interactions and event discussions—empowering teams to act on data in ways they never thought possible.
Tell us about your company.
Voxo is an AI event content partner. We capture everything spoken on stage: keynotes, panels, and roundtables, and turn it into structured, branded, shareable content within minutes of a session ending.
We started in Stockholm in 2016, initially in conversational analytics for financial advisory and customer service. That product taught us what it actually takes to build reliable speech AI in demanding real-world environments, with accuracy requirements, speaker variations, and real-time latency.
The pivot to events came from a clear market signal. We summarized all stage sessions at Techarena 2024, Scandinavia’s largest tech conference. The demand afterward was immediate, and we decided to launch this as an event-specific product.
Today, we work with enterprise customers globally. Partners include event tech platforms such as RainFocus and Amego, and customers such as HubSpot, GitHub, and Intuit.
What problems are you solving?
Events are among the most information-dense environments in the world, and almost all of that intelligence evaporates the moment a session ends. A speaker walks off stage after 45 minutes and without a summary, the insights are effectively gone. Our summaries are live minutes after the speakers walk off the stage, with key takeaways that are branded and ready-to-post on social media.
On the production side, creating post-event content from hundreds of sessions takes marketing teams weeks. By then, the audience has moved on. Our customers tell us that for them to create what Voxo delivers in a day would have taken their teams months.
For attendees, the service adds more value to the event experience. It’s impossible to be in three sessions at once. With Voxo, they get a summary of every session they missed, available immediately. At The AI Summit New York, that meant 25,000 summary downloads across roughly 200 sessions. The content doesn’t expire; it can be used for future marketing efforts to promote next year’s event.
What application areas are your strongest?
Enterprise conferences and large-scale industry summits. Multi-day, multi-track events with demanding quality standards and marketing teams that need to move fast. We’re also about to launch a self-service SaaS platform for events as well, that’ll make it easier for smaller organizations and enterprise organizers to utilize the whole event agenda in their content schedule during and after the event.
What keeps your customers up at night?
Accuracy. Publishing something inaccurate for a global event brand is a real risk. One wrong summary published with the wrong company name or speaker could be damaging. That’s why we built a human-in-the-loop review into the workflow. We train our event specialists to review quickly so we don’t lose the speed advantage.
Other than that, it’s quality. We have to maintain quality across 200 sessions simultaneously, with sometimes imperfect audio, accented speakers, and no time to redo anything. That’s what we’re built for.
And beyond that, there’s the ROI question. Events are expensive. Sponsorships are expensive. So our customers need to show that their event is actually creating value for stakeholders. We measure every summary download and can connect it to the personal data from the event apps, so the sponsors get more visibility and also tangible ROI.
What does the competitive landscape look like and how do you differentiate?
There are a lot of transcription tools out there like Otter and Fireflies, and now a wave of AI tools built for events. But what’s different about our offer is that we’re not just another tool that generates summaries. We’ve focused on the layer around it, how content is actually captured, structured, branded and quality-checked. Because that’s the hard part at scale, event marketers know this better than anyone else.
Capturing and creating content at a multi-stage event is a massive undertaking, and we’re adding a layer of valuable content that benefits everyone from organizers and speakers, to attendees.
We’ve also seen on-demand viewing increase by up to 400% when summaries create that initial interest, so it feeds into the already existing event content structure as well.
What new features and technology are you working on?
We’re focusing on deepening the personalization for attendees. Right now, we deliver session summaries to everyone equally. The next step is understanding who the attendee is (their role, their interests, what they attended) and surfacing content most relevant to them. This is a feature we’re delivering for the first time in June with an enterprise client.
Within the year, we will release a fully customizable content lab with new formats, more interactive content, and deep integrations into social media platforms. Earlier this year, we released AI Podcasts that are created on-the-fly during the event, and we’re also experimenting with motion graphics and automated video creation to be released soon!
The self-service platform will be a major release from us, enabling the vast majority of the market to use the same tools we provide to our enterprise clients today to medium and smaller companies as well.
How do customers normally engage with your company?
Event organizers or enterprise marketing teams often find us through a recommendation or from attending an event we’ve summarized. If it’s through an event, then they’ve experienced the attendee side of the summaries and usually pretty intrigued right off the bat.
Or it’s through event platform partnerships like RainFocus or Amego. The organizer is already using their platform; they see Voxo as a partner, and the integration is smooth sailing from there.
The best salespeople are our existing happy customers, which is something we’re really proud of since we’re a new technology application in the event industry. So far, more than 90% of our clients from 2025 have signed up for the services again for this year.
