Supra Insider

What if the reason you feel like you never have enough time isn’t actually a time problem at all?
In this episode of Supra Insider, Marc Baselga and Ben Erez sit down with Molly Siemers, an executive coach for product leaders who spent over two decades building mission-driven products at companies like Kiva, Change.org, and Blurb before launching her coaching practice, Product Craft Works. Molly opens by naming what she's watching in real time: product leaders are running faster than ever, layoffs are everywhere, and the pressure to adopt AI on top of everything else is creating a new kind of cognitive overload. Coaching, she argues, has never been more necessary, not because people need tactics, but because most people are solving the wrong problem.
They explore the difference between time and capacity, why the best senior leaders seem unflappable, and how personal capacity is something you build, not something you find by rearranging your calendar. Molly walks through the integral coaching methodology she trained in, the threshold practice she gives clients to start tapping into body and emotional intelligence, and the three-step framework she keeps returning to: notice, decide, act. The conversation then turns personal, with Marc and Ben reflecting on agency, identity, and what happens when you look around and realize you’ve built a job you hate, or, on the flip side, a life that actually works.
If you’re a product leader feeling overwhelmed and can’t figure out why, someone navigating a career transition and struggling with identity, or a founder or operator who’s curious whether coaching might actually be worth it, this episode is for you.

What if you could know whether your product change was going to work — before a single real user ever saw it?
In this episode of Supra Insider, Marc Baselga and Ben Erez sit down with Tom Charman, co-founder of Blok, a synthetic user simulation platform that lets product teams test interfaces, onboarding flows, and product changes against AI-powered behavioral personas, not just to predict conversion, but to model second and third order effects like churn, confusion, and long-term retention. Tom opens by naming what’s changed: shipping is faster than ever, but the tools PMs use to decide what to build haven’t kept up. AB tests still take two to three weeks. Traditional user research still skews toward power users. And as personalization gets more complex, getting to statistical significance gets harder. That’s the gap Blok is trying to close.
They explore how Blok’s behavioral personas go beyond demographics to model psychographics, emotional state, and memory, including what happens when a user has a bad first experience and comes back to your product skeptical. Tom walks through the ICP trap that kills retention, why the “show don’t tell” principle protects against confirmation bias, and why he thinks the biggest shift happening in product right now is the move from reactive to proactive, replacing AB tests and feature flags with pre-ship simulation that gets you to directional confidence in 12 minutes instead of three weeks.
If you’re a PM tired of going to battle in product reviews without data to back your intuition, a founder trying to understand how synthetic users actually work and whether they’re worth it before Series A, or a product leader looking to understand how the entire feedback loop from idea to deployment is about to be rebuilt, this episode is for you.

What happens to the PM, the designer, and the engineer when a single person with a great idea can take it all the way to market on their own?
In this episode of Supra Insider, Ben Erez sits down with Tomer Cohen, former Chief Product Officer at LinkedIn, where he spent 14 years and led the company’s product transformation through the AI era. Tomer unpacks the full stack builder mindset - not as a job title, but as a fundamental rethinking of how product development works when the bloated, process-heavy model of the last two decades gets collapsed back down to its original building blocks: idea, build, ship.
They explore how Tomer actually rolled this out at LinkedIn across thousands of people, including replacing the traditional APM program with one where candidates submit a working product instead of a resume, and where the final interview is building something end to end in real time. He breaks down the three archetypes he sees emerging - system builders, full stack builders, and specialists - and what he observed clearly separating top performers from the rest: not their tooling, but their judgment. The conversation closes with a Q&A covering how to navigate interpersonal friction as roles blur, when you actually need a specialist to step in, and what skills will remain stubbornly human no matter what.
If you’re a PM, designer, or engineer trying to understand where your role is actually heading and what to do about it right now, trying to think clearly about how to future-proof your career without falling for hype, or curious how a CPO at one of the biggest tech companies in the world actually tried to operationalize this shift - this episode is for you.

What if the cognitive overhead of constant context-switching, endless meetings, and deciding what to work on next could be offloaded to a system that actually knows how you think?
In this episode of Supra Insider, Marc Baselga and Ben Erez sit down with Michael Leibovich, a business unit leader at Adobe overseeing product, design, support, and business strategy, who spent his paternity leave building something most people only talk about: a fully personalized AI chief of staff, built on Claude Code, powered by nothing more than folders and markdown files.
They explore the architecture behind Michael’s system in detail, from session memory and mental models to a people file that auto-updates from meeting transcripts, a knowledge graph that grows over time, and scheduled tasks for daily meeting metabolization and weekly competitive intel. Michael walks through how he bootstrapped his minimum viable context by extracting from ChatGPT’s memory in under ten minutes, why Obsidian became his visual interface of choice, and the moment he realized this was genuinely worth the investment: getting a suggested answer to “what is the highest leverage thing I should do right now?” in a 30-minute gap between meetings.
If you’re a non-technical operator overwhelmed by AI tooling and unsure where to start, a leader constantly context-switching between teams who struggles to protect time for deep work, or someone building out your own context infrastructure and looking for a real-world playbook, this episode is for you.

What if the reason great talent keeps failing at your company has nothing to do with the talent — and everything to do with the environment you built around them?
In this episode of Supra Insider, Marc Baselga and Ben Erez sit down with Hiten Shah, serial entrepreneur and co-founder of Crazy Egg, who recently had his first-ever job as a PM at Dropbox after selling his company to them. That 15-month experience as an individual contributor — after a lifetime of being the one who owned the environment — completely changed how he thinks about leadership. Hiten unpacks the viral post that kicked off this conversation and introduces a framework most people have never articulated: vibe leads to environment, and environment leads to culture.
They explore what happens when leaders lose ground-level visibility, why escalation is actually healthy in large organizations, and how Hiten’s startup FYI built a concrete interview process to hire specifically for environment fit. The conversation moves through the Toby Lütke / Shopify story, the “nothing changes without fireworks” principle, and why most CEOs are outsourcing environment visibility to the wrong people — before pivoting into Hiten’s current obsession: running OpenClaw bots inside Slack, pair prompting, and how a two-bot thread with 800 messages built an entire product without Hiten touching a line of code.
If you’re a founder who’s started to feel like a prisoner in the company you built, a leader trying to figure out why strong people keep underperforming, or a non-engineer looking to get serious leverage from OpenClaw bots without using Claude Code — this episode is for you.
