Dear Fusemachines Family,

The moment we have all been waiting for is finally here!

I am so pleased to share that Fusemachines Inc. is planning to be publicly traded soon when we complete a business combination with a special purpose acquisition company. Not only that, we expect to be listed on NASDAQ – one of the most coveted stock exchanges in the world! For a company that has been carrying the torch of Democratizing AI – since the time when AI was just a novelty – to be making history by being the first-ever company of Nepalese origin to be listed on NASDAQ will be nothing short of surreal.

So, congratulations to each and every one of you who has been part of this 11-year journey with us. Your dedication and drive has always been the guiding force for me and the leadership team. Without your hard work, patience, and innovative thinking, this momentous milestone wouldn’t have been possible.

Now, what’s next from here?

As you know, for the past several months, Fusemachines’ leadership team has been laying the foundations to ensure we are on track to deliver best-in-class AI solutions, develop products that will shape the future of enterprise AI, and training programs that will yield an elite pool of data and AI talent.

With our plans to become a publicly traded company, it becomes more critical than ever to stay laser focused on the goals because becoming a public company comes with more than just pride and enthusiasm. It comes with the responsibility of constantly delivering to an even bigger pool of stakeholders. Once we become public, we’ll have the eyes of the world on us and performance across the board will be key. Everything from our financial performance to corporate governance will be of interest to our stakeholders. Meeting every single target and checking off every single OKR will be imperative. This will be particularly true for the months leading up to the actual NASDAQ listing, which we expect to occur in or around the second quarter of this year.

Becoming public also means that we will have access to additional sources of capital and we want to be able to leverage that for explosive yet strategic growth and expansion. Our evolution will not only be in size but also in what we have to offer to the market. As I mentioned in the recent Townhall, we are emerging as an Enterprise AI Products and Solutions company. This means everyone’s collective efforts will be needed to turn our dreams of AI Studio, AI Engines, and a stellar team of domain and industry experts into hard reality.

Needless to say, during this growth stage, we cannot lose sight of our culture of camaraderie and the spirit of Democratizing AI. As we expand to new markets, we will continue to stay true to the fabric of our mission and values and continue our AI Education program in underserved communities around the world, especially in Nepal.

On the individual front, we want to ensure that you continue to take pride in your performance. For this, we will have your reviews and imminent appraisals directly linked to your performance. Additionally, as you know, depending on your years of engagement with Fusemachines, we have handed out stock options to some employees. Regarding how the public listing affects your specific shares, the finance and HR teams will be hosting short sessions for those interested over the next few days. Stay tuned!

For now, it’s a moment of joy and celebration. So, please feel free to step away from your laptops to take in this victorious moment. Share our great news with your friends and family, and continue to take pride in yourselves and in the organization, today and always. Then, let’s gear up for what will be two of the most important quarters in the history of Fusemachines.

Once again, many congratulations to all of us!

Best,

Founder & CEO, Sameer Maskey, PhD
