Four years ago, we got introduced to Arturo, the CEO of Mnemo Inc., and their idea for reinventing the old apartment callbox. What started as a simple tablet that called tenants on their phone, has grown into Whoo.ai, an AI-powered assistant used in buildings, offices, and even public transport.

Here’s a look back at that journey and how it’s been for us at Raskenlund as a long-term technological partner.

Four years ago, on October 22nd, I was introduced to Arturo, the CEO of Mnemo Inc., through a mutual connection, Rob (a then-customer) who told me we might have something in common.

He was right.

At that time, Mnemo had a product called Whoo.ai, an intelligent replacement for the old call boxes in apartment buildings. Instead of hoping the tenant was at home to buzz someone in, Whoo used a tablet that could reach the tenant through an app or a phone call. It was simple, logical, and at the MVP stage, with around a hundred installations already live.

From the first conversations it was clear that Arturo had vision. He didn’t just think about solving building access. He was rethinking how people interact. And from our side at Raskenlund, with years of experience in video-calling systems and full-stack development, we saw the potential to help Whoo.ai with the next steps.

When we first got involved, the product worked; but like most MVPs, it needed additional security, scalability, and architectural consistency. Our first step was to make the platform more robust and systematic across its different components.

Over time, the concept evolved beyond access management. Arturo saw the opportunity that combining Access Management with Virtual Assistance could open up new possibilities. And that AI would be in the center of that.

Today, Whoo.ai is used not only by property managers but also in offices, public transport, and event spaces. It can help office visitors find the right person, guide football fans to their seats, or assist tourists in navigating public transport in their own language.

In four years, from a callbox replacement to a full-fledged AI-powered assistant – what a journey!

In 2023, Mnemo and Raskenlund formalized our collaboration through a long-term partnership. From the start we had assigned Lars, one of our senior solution architects, as dedicated contact to bridge technical strategy and business goals.

Over the past four years, Raskenlund has contributed architecture, full-stack development, integrations (including payment systems and data lakes), and acted as technical advisors to the Whoo.ai team. Together, we’ve implemented everything from multi-provider video-calling (WebRTC, SIP, VoIP) to building an MCP server that connects AI logic with real-time user interaction.

Our team already had deep experience in building complex systems, but every long-term partnership teaches you something.

With Whoo.ai, we refined how we distinguish between POC, MVP, and Enterprise-grade solutions – technically and strategically. We’ve strengthened our understanding of consistency, reliability, and scalability at multiple levels.

Most importantly, we built mutual trust. Arturo trusted our competence; we trusted his vision. That balance between product vision and technical execution is what makes a partnership last.

Today, Whoo.ai is a truly international and multicultural team – with people across Latin America, the U.S., and Europe – continuing to expand the vision.

As for Raskenlund, we’re staying on as a technology partner, continuing to grow together – not necessarily in size, but in competence and practical experience.

We’re exploring how AI can be used meaningfully, not just as a buzzword or an LLM wrapper, but as a core enabler of smarter, human-centered experiences.

Four years in, and excited for what’s next!
