03/03/25 • 26 min

While American AI startups are dominating the headlines, one Japanese company has begun rolling out "AI employees" to famously cautious Japanese enterprise customers. Today we talk with Shota Nakagawa the CEO of Caster and discuss their model of human-AI collaboration, why Japan is positioned to lead real-world AI deployment, and the big steps needed for Japan to catch up with the West. It's a great conversation, and I think you'll enjoy it. Show Notes Caster’s new model for gig-workers Why almost 90% of Caster's workforce are women How remote work is evolving differently in Japan than in the US Can remote work really revitalise rural Japan? Why Caster uses full time staff rather than gig workers How AI employees could be the solution to Japan’s labor shortage How Caster makes extensive use of AI in their workflow today What is responsoble for the low level of trust that Japanese have in AI and how to fix it Which tasks AI agents will take over and which they will never do Links from our Guest Everything you ever wanted to know about Caster Follow Caster on X @caster_jp Friend Caster on Facebook Friend Shota on Facebook Follow him on X @nakasy000 Leave a comment Errata Caster's percentage of female employees is about 87% not 95%. Caster was founded in Tokyo, later moved to Miyazaki, and then moved back to Tokyo after the IPO Transcript Welcome to Disrupting Japan, Straight Talk from Japan's most innovative founders and VCs. I'm Tim Romero, and thanks for joining me. While American CEOs are competing to see how quickly they can leverage AI to replace both full-time employees and gig workers alike, one Japanese company is taking a different approach and they're already rolling out their AI workforce. Today we sit down with Shota Nakagawa, founder and CEO of Caster. Now, Caster is a remarkably progressive and innovative Japanese company. They were a strong and vocal advocate of remote work years before the pandemic hit, and even after their IPO, their 800 person workforce remains fully remote with our corporate headquarters located in a shared office space in Tokyo. Caster has now begun rolling out its AI workforce, and they're taking a very Japanese approach. Rather than leveraging a collection of flexible gig workers or freelancers, Caster continues to build a long-term full-time workforce who is co-developing and already working alongside their AI employees. If history is any guide, Caster’s thinking today might tell us what the Japanese market will be thinking 10 years from now. Shota and I talk about the long-term AI trends in Japan, how Caster solve the problem of corporate, Japan's deep skepticism about AI and whether or not AI can really provide a solution to the economic problems associated with Japan's declining population. But, you know, Shota tells that story much better than I can. So, let's get right to the interview. Interview Tim: So, I'm sitting here with Shota Nakagawa, the founder and CEO of Caster, who is creator of an outsourcing platform and a relentless advocate of remote work. So thanks for sitting down with me. Shota: Thank you very much. Tim: So, I explained very briefly what Caster did in the intro, but I think you can explain it much better than I can. So, what does Caster do? Why is it unique? Shota: People are all work remote every day, every day. Tim: So, the entire company is remote. Shota: Yeah, yeah. All people. Tim: That's pretty unusual. And we're here today actually sitting in a share office space to have this conversation. Well, actually let's talk about that in detail later. But first, let's talk a little more about Caster. So, what do you do for your customers? Shota: BPO, business process outsourcing, client about SMB small business, want back office service. Tim: So, what kind of back office services, is it like recruiting, accounting? Shota: Many types. Tim: So,

I'm Tim Romero, and thanks for joining me. I didn't really realize what this episode was about until I finished the editing. Oh, don't worry. I'll be introducing you to an innovative founder in just a minute, and we'll dive deep into their business and their market. But this episode is really about stereotypes, how much truth they really have and why they stay with us, and what we can do to change both the perceptions and the realities that underlie them. Today we sit down with Kunio Hara, co-founder and CEO of Beatrust, a startup that's focused on getting Japanese enterprises to break from their hierarchical structures and let their employees collaborate. Listeners who have spent time in Japan know that this is not an easy task, but as we explore this subject, it becomes clear that both the reality and the solutions are not as straightforward as the stereotype suggest. We also explore the stereotype of the young Rebel startup founder, and man that is a pervasive one. In 2007, a 22-year-old, Mark Zuckerberg famously declared that quote, young people are just smarter. Paul Graham explained in 2013 that investors tend to be skeptical of any founder who is over 32 years old. However, if you take the time to look at the real world results, the data actually show that older founders are much more likely to have a large value exit than younger founders. Kunio started Beatrust in his late fifties, and we talk about the positives and the negatives associated with that. But, you know, Kunio tells that story much better than I can. So let's get right to the interview. Interview Tim: So, I'm sitting here with Kunio Hara, the co-founder and CEO of Beatrust, who is modernizing corporate collaboration and culture in Japan. So, thanks for sitting down with me. Kunio: Yeah, thank you, Tim. Long time no see. Tim: Yeah, it has been a while since you're at Google. So Beatrust is focused on helping employees collaborate. This is important. Everyone agrees it's important. But it's hard. So what is Beatrust doing differently in this space? Kunio: We call our service talent collaboration tools because we try to define the new space and compare with other HR tech, especially talent management. What we do is mainly to help large organizations drive and facilitate more autonomous collaboration like cross functions. Tim: Okay. Yeah, that's challenging and in a bit, I want to dive deep into exactly how you do that. But before that, tell me about your customers. So, who's using Beatrust? Kunio: Obviously, large enterprise customers. They want to transform the culture to more innovative oriented,
