Hello and welcome to another
SPACInsider podcast, where we bring an independent eye in interviewing the targets of SPAC transactions and their SPAC partners. Agentic AI is here and working in a number of industries, but the question of which model can win is increasingly
defined by who has the data to back it up. I’m Nick Clayton, and this week, I speak with Anindya Datta, CEO of Mobilewalla, and Bala Padmakumar, CEO and Chairman of SPACSphere Acquisition Corp. The two announced a $250 million combination
in June. Anindya explains how Mobilewalla’s long tail of data forms the backbone of its own AI offerings, and how it has innovated internally to give it an edge. Bala gets into why he sees Mobilewalla as standing above the noise in the AI
space and how SPACSphere concluded it was ready for the public markets. Take a listen.
And so, Anindya, Mobilewalla was founded in 2012. I imagine so
much has changed in the time in between. Do you have a quick version of the story of how Mobilewalla has changed, and how it’s modified its approach and solving problems for clients with all that technological change over that time?
Anindya Datta
Yes, super interesting questions, and
takes me back in time. So to understand how Mobilewalla started, I’ll take you back to my background. I started my career as a practicing computer scientist, as a sort of young faculty member at Georgia Tech, in computer science.
And my computer science work and research was in AI. When I started my career in the late 90s, early 2000s, AI was not sexy at all. In fact, listeners who
were in the same boat as me would empathize with me that people would make fun of AI — other computer science groups would say that nothing is ever going to come of AI, you guys are gonna build toy systems forever. That situation has now
changed.
My work was always at the intersection of AI and data — the impact of data on AI. And to tell you how Mobilewalla started, let me just
give this sort of preamble: all AI is basically, regardless of what flavor of AI — these days we talk of generative AI, which is really a tiny, tiny part of AI — all AI, machine learning, neural networks, any flavor, is basically a
marriage between a technique and data. You have a technique, you have an algorithm, and you train it on some data, and this data is really a manifestation of some period of history — rainfall in Georgia, or mango production in the Philippines,
or whatever. You take this data that manifests history over a period of time, and you apply this technique or algorithm on it, and what it does is that it finds patterns in the data that repeat. And then once it has found those, it basically looks
for those patterns in ongoing stuff, and it predicts, like, next year mango production is going to be good or bad, or next week how much rainfall is going to be there in Atlanta. All AI, all prediction, at a very abstract level, is a marriage
between algorithm and data.
My work was focused on, sort of, the interrelationship between these two. When you build an AI model, you build it by
applying an algorithm on data and what are the relative impacts of data and algorithm on that model — which is more important. In the field of AI for 40 years, every practitioner, every researcher chased the algorithm, because it was believed
that better algorithms are going to lead to better predictions — the reason that predictions were not good was thought to be that the techniques being applied were not powerful. And you’ll see that one of my theses was that perhaps that
was not the case. Perhaps data is more important than what we believed.
