That requires sitting in their shoes, really knowing their environment, their goals, and the pressures they face.

When AI Meets Legal feat. Eleanor Lightbody, CEO of Luminance
Is it possible to build and scale AI tooling for one of the world’s most risk-averse industries while instilling trust in your users?

Throughout their conversation, Francois and Eleanor highlight different strategies for building user trust.

Some are simple: if your models can’t deliver an answer with confidence, let the human know so they can verify.You’ll also hear Eleanor discuss how her team uses AI across the business, why speed is a competitive advantage, and what it means to lead a global company outside Silicon Valley.Whether you’re building AI in a high-stakes domain or leading transformation in a legacy industry, this episode offers practical insights on trust, innovation, and scaling with purpose.—Guest BioEleanor is CEO of Luminance.

Then we figure out what the human should do. The speed advantage is massive. Not just for delivery, but for getting the feedback loop faster, and that is gonna set you up for success. Speed has always been important, but in this new era that everyone’s operating in, I would say it’s probably one of the most important things.” – Eleanor Lightbody—Time Stamps 00:00 Episode Start01:23 What is Luminance?02:34 Why specialized AI is primed for legal teams07:20 The largest roadblocks to widespread adoption09:52 How do you measure success?11:56 Building confidence across your organization14:50 Staying ahead of the curve18:06 Eleanor's journey to Luminance22:12 Optimize for learning24:07 Leading globally26:56 Advice for aspiring CEOs31:15 Eleanor's "Oh Sh*t Moment"—LinksConnect with Eleanor Lightbody on LinkedInCheck out LuminanceConnect with Francois Ajenstat on LinkedInCheck out Amplitude Hosted by Simplecast, an AdsWizz company.

Crafting an Iconic Legacy Brand with Telstra's CMO Brent Smart
Today on Next Gen Builders, Francois welcomes Brent Smart, the CMO at Australian Telco giant, Telstra. Their conversation focuses on the power of brand as Brent has been the leading charge behind Telstra’s new brand platform. Throughout the episode, Brent argues for connecting your marketing efforts to the real world. When trying to evaluate how Telstra appeared to consumers, his team ran surveys asking Australians to draw, not write, what they thought of the organization. Similarly, he consistently advocates for running live experiments to validate your approaches in real time. The episode also explores how Brent aligns teams around a unified brand vision with tools created in house, such as “Telstra’s Creative Dial,” to help measure and guide creative output. He stresses the value of a distinct brand voice and explains why starting with a small, focused team helps nurture new ideas.Drawing on his transition from agency life to leading Telstra’s marketing, Brent offers a fresh perspective on keeping creativity alive in a corporate setting. His commitment to hands-on idea generation and real-world testing over pre-market research makes this episode essential for anyone seeking meaningful brand transformation.—Guest BioA leading global marketer and a passionate speaker on creativity, brand and culture, Brent Smart is Chief Marketing Officer of Australia's second most valuable brand, Telstra.Previously, Brent spent five years as CMO of Australian insurance giant IAG, where his work on NRMA Insurance took it from 36th strongest brand in Australia to 5th, winning 3 Gold effectiveness awards and the coveted Grand Effie in 2021.

When the brand is strong, the performance marketing actually works better. We've seen our short term ROIs actually go up, not go down. The brand doesn't just help with this quarter's numbers, it helps with next quarter’s and beyond. And once you give it time to start building, you can start showing that not just the brand metrics are healthy, also our short term performance metrics are healthy. But you need time. It's not gonna show in the first quarter. You gotta wait.” – Brent Smart—Time Stamps 00:00 Episode Start2:00 The power of brand05:10 Evaluating your brand08:35 Finding your brand voice12:10 Building conviction within your organization15:05 Start experimenting in the real world17:40 Leading by doing19:45 Taxi or Bus Meeting22:00 What does a good pitch feel like?27:35 Discipline liberates creativity30:00 Can you teach taste?34:20 Brent's journey to CMO—LinksConnect with Brent Smart on LinkedInCheck out TelstraConnect with Francois Ajenstat on LinkedInCheck out Amplitude Hosted by Simplecast, an AdsWizz company.

Today on Next Gen Builders, Francois speaks with Edik Mitelman, SVP & General Manager of AppsFlyer Privacy Cloud, the trusted open platform for ecosystem collaboration and innovation with a clear mission: Enhancing end-users experience, while preserving their privacy.Their conversation covers the challenges and strategies for building a startup within a larger organization, and why you would even do it in the first place. Edik highlights how a smaller, resource-limited team can align themselves much closer with their users, ensuring each line of code they produce serves a clear purpose. Francois & Edik also touch on the role Product Managers should be serving within organizations and how they compare and contrast across various company sizes. One glaring similarity in Edik’s mind? The importance of maintaining a beginner’s mindset. In his words “ experience is important…but we as product managers must assume that we don't know and we need to test our hypotheses.”Finally, Edik shares his thoughts around risk and failure. He stresses that more organizations should be comfortable with potential failure in order to foster an environment full of experimentation. Through each iteration, your team will gain learned experiences that will lay the groundwork for your next big success.—AppsFlyer Update Since we recorded this episode, the journey Edik discusses of building what's essentially a startup within AppsFlyer is bearing fruit, with AppsFlyer's Data Collaboration Platform being used across several industries -- including quick commerce, consumer packaged goods, and financial services. The results for early adopters are impressive: marketing campaigns for brands using the product have seen up to 400% return on their ad spend and significant performance uplifts for their businesses. The partnerships embody what we talked about regarding the advantages of building a startup within an established company — leveraging AppsFlyer's resources, credibility and relationships while maintaining the innovative spirit and customer focus that drives true product-market fit. It's a real-world example of transforming concept into practice, process into product, and experience into measurable success.—Guest BioEdik Mitelman is the General Manager of Privacy Cloud at AppsFlyer, an ecosystem collaboration and innovation environment which preserves end-user privacy. Edik is an experienced executive with previous leadership roles at Autodesk, Wochit, and Conduit. He also runs the Venture Creation and Product Innovation program as part of the GMBA at Reichman University.—Guest Quote ”As product managers, we must do what customers need. So if you sold it and you don't care anymore, you will never care for that customer any longer, until maybe the renewal time comes up. I want my PMs to constantly worry about their customers, and to constantly deliver value throughout the year. So that people use our products more and more.” – Edik Mitelman—Time Stamps 00:00 Episode Start01:45 When Edik left engineering for product03:50 Maintaining a beginner's mindset05:20 How the role of product varies between organizations08:25 Building multiple startups within a single orga nization10:15 Edik's work on AppsFlyer Privacy Cloud13:45 The advantages that come from a startup mentality17:05 Measuring success20:55 Ensuring your team is rowing together 24:40 Failure breeds success 32:45 Are GMs for everyone?—LinksConnect with Edik MitelmanCheck out AppsFlyerCheck out the AppsFlyer Privacy CloudConnect with Francois Ajenstat on LinkedInCheck out Amplitude Hosted by Simplecast, an AdsWizz company.

High-Growth Communities with Carlos Gonzalez de Villaumbrosia, Founder & CEO of Product School
Welcome to Season 02 of Next Gen Builders! Today, Francois sits down with fellow podcast host Carlos Gonzalez de Villaumbrosia, Founder & CEO of Product School, the global leader in Product Management training. Their conversation covers how Carlos scaled Product School from the ground up, why community building has been a key factor in his success, and what truly makes a great product leader. Carlos founded Product School in 2014 with a vision of democratizing access to education and has since grown the community to over 2M members. He reflects upon what ingredients have led to the organization’s success alongside what he may have done differently if given the opportunity again. Ultimately though, Product School is proof that community matters regardless of the business you are in.Additionally, Francois and Carlos talk about The Product Podcast and how impactful it has been in tandem with Product School. With over 260 interviews featuring product executives from brands such as Nike, the NBA, Duolingo, and Amplitude, Carlos has had the opportunity to truly understand the makeup of a great product leader. So right after tuning into Next Gen Builders, check out The Product Podcast!—Guest BioCarlos Gonzalez de Villaumbrosia is an entrepreneur with over 15 years of experience building global companies and digital products.He founded Product School in 2014, which is the global leader in product training with a community of over two million members. All of Product School's instructors are real-world Product Leaders working at top Silicon Valley companies including Google, Meta, Netflix, Airbnb, Uber, and Amazon. Prior to Product School, he founded Floqq, the largest online education marketplace in Spanish and Portuguese at the time. Floqq joined the 500 Startups and Startup Chile accelerator programs.Additionally, Carlos co-authored the Amazon bestseller The Product Book, and has participated as a speaker in more than 1,000 events, conferences, and classes around the world. Outside of work, he loves skiing and playing tennis.—Guest Quote" Community is a term that is now being overused and sometimes misunderstood as, ‘Oh, let's just start giving something away with an expectation of getting something in return.’ And I think that kind of defeats the definition of a community. True, you as a business need to have a business model to keep the lights on and grow, but building a community to me is a strategy, it's not a tactic. To me that meant I'm going to build something for the long term. I have a mission which is helping people build better products and democratize access to education in ways that some of the people that actually benefit from the community might never be able to pay economically. And I'm okay with that. And so it starts from that mindset, without obviously forgetting about the business model. That is how I think of community, as a strategy.” – Carlos Gonzalez de Villaumbrosia—Time Stamps 00:00 Episode Start01:45 What is Product School?04:00 How Carlos was able to scale 08:05 Lessons learned along the way10:55 Creating & measuring meaningful communities14:30 The Product Podcast18:00 What makes a great product leader21:10 Transforming with AI effectively26:20 Overcoming doubts and hesitations29:40 Carlos' advice for others leaning into innovations 33:20 Maintaining flexibility throughout a transformation34:50 What Product School is focused on in 2025—LinksConnect with Carlos Gonzalez de Villaumbrosia on LinkedInCheck out Product SchoolWatch The Product PodcastConnect with Francois Ajenstat on LinkedInCheck out Amplitude Hosted by Simplecast, an AdsWizz company.
