Apr 900:45:43Tap to summarizeThis week’s guest is Ayal Yogev, co-founder and CEO of Anjuna Security, who has experienced both sides of the startup journey: scaling quickly during the boom years and then making the incredibly difficult decision to lay off a significant portion of his team when the market shifted.

Diverse teams start with diverse VCs with Leah Solivan, Taskrabbit
Apr 200:46:51Tap to summarizeIf one thing has become clear this season, finding the right talent for your team isn’t as easy as picking from a pile of resumes This week’s guest is Leah Solivan, the founder of Taskrabbit and now an early-stage investor who has seen that the power to change a homogenous startup exosystem comes from empowering diverse VCs to fund underrepresented founders who will hire the hidden tech talent.

Why hiring the weirdos works with Isaiah Granet, Bland
Mar 2600:50:01Tap to summarizeIf one thing has become clear this season, it’s that there is no formula to building the perfect team. But no one breaks the mold quite like this week’s guest, Isaiah Granet, the co-founder and CEO of Bland. The voice AI startup has been growing at a breakneck speed but the founding team has taken their time to prioritize passion over pedigree and find their team members in places many might not think to look. In this episode, Isabelle Johannessen and Isaiah Granet unpack a radically different approach to hiring that prioritizes aligned work ethic, curiosity, and flexibility rather than resumes and connections. So far, that approach has worked for Bland. The scrappy team has gone from pre-seed to series B in less than a year. They discuss: How to identify “hidden gem” talent in unexpected places The role of cold inbound and unconventional sourcing When to hire ahead of need and when not to How hiring philosophy shapes company culture at scale Apply to Startup Battlefield: We are looking for early-stage companies that have an MVP.

How to fight with your co-founder with Ian Schmidt, Trimergence
Mar 1900:48:35Tap to summarizeEvery founding team is a mix of personalities, communication styles, and strengths. That can be a superpower or cause founders to butt heads. Without a clear framework for navigating conflict, even the strongest teams can fall apart before they really get started. This week on Build Mode, Isabelle Johannessen sits down with Ian Schmidt, strategic advisor at Trimergence, to unpack the “personal operating system” behind every founder. As a coach, consultant, and occasionally a bouncer, Ian helps teams build the self-awareness and relational tools they need to scale without unnecessary friction. They discuss: Why founders should invest in coaching before conflict escalates How to repair after conflict goes sideways The importance of understanding your own triggers as a leader How to create space for the self-work that actually saves time long-term Following last week’s episode on family co-founders, this conversation expands those lessons into practical tools any founding team can use.

Building a lean team before raising big with David Park, Narada
Mar 500:38:13Tap to summarizeThis week on Build Mode, we’re joined by David Park, co-founder and CEO of Narada, an enterprise AI agent platform spun out of UC Berkeley AI Lab research. Narada uses large action models to automate complex, multi-step workflows across enterprise systems. After previously co-founding and exiting Coverity, Park is now building his second company with a different playbook: Stay lean, talk to customers, and don’t raise before you’re ready. In this episode, he shares why Narada spent a year making nearly 1,000 customer calls before raising institutional capital, how the company reached 99.99% reliability in production environments, and why he believes too much funding too early can derail even the strongest teams. Park also reflects on his experience as a Startup Battlefield Top 20 company and the lessons he’s carried from his first exit into building Narada. He breaks down: Why customers won’t tell you your “baby is ugly” — but their wallets will How Narada achieves enterprise-grade AI reliability Why raising money before product-market fit can be dangerous The discipline of building a lean, “mean building machine” When to scale your go-to-market team (and when not to) Why founders must stick to their values, even under pressure Lessons from Startup Battlefield and building in public Apply to Startup Battlefield: We are looking for early-stage companies that have an MVP.
