  The legal mistakes that can sink your startup before series A with Kristina Subbotina, Lexsy 07.08.2026 41min

  Setting up a sound legal foundation could be what saves a startup down the line. A missing founder vesting agreement, an unclear IP agreement, or a messy cap table can derail fundraising, spark co-founder disputes, or even kill an otherwise promising company before it has a chance to scale. In this episode of Build Mode, host Isabelle Johannesen sits down with Kristina Subbotinai, founder and CEO of Lesxy and former startup attorney at Cooley, to break down the legal fundamentals every founder needs to get right. Kristina shares the four non-negotiable legal decisions every startup should make from day one, what investors actually look for during due diligence, how founders should think about negotiating control versus valuation, and why leverage is the key to getting better fundraising terms. She also shares real stories from the front lines of startup law, from co-founder breakups and investor negotiations to a founder who tried using ChatGPT to draft a merger agreement. They get into: The four legal mistakes that can make a startup unfundable How founder vesting, IP assignment, Delaware incorporation, and 83(b) elections protect your company What VCs actually look for during due diligence and how to avoid common red flags How founders should negotiate valuation, board control, and investor rights Why leverage comes from building a great business—not signing better term sheets The wildest legal horror stories Kristina has seen, including a startup acquisition gone completely off the rails Subscribe to Build Mode on⁠ Apple Podcasts⁠, ⁠Spotify⁠, or⁠ wherever you like to listen⁠.

  Why SeatGeek walked away from going public with Jack Groetzinger 30.07.2026 26min

  SeatGeek didn't become one of the biggest names in ticketing by following the playbook. It started as a simple ticket search engine on the TechCrunch 50 stage (now known as TechCrunch Battlefield) and took on the industry’s massive incumbents by expanding its vision, surviving industry-defining challenges, and convincing investors that even a monopoly could be disrupted. In this episode of Build Mode, host and Startup Battlefield lead Isabelle Johannesen sits down with Jack Groetzinger, co-founder and CEO of SeatGeek, to unpack the company's 17-year journey from startup to industry leader. Jack shares how SeatGeek raised nearly $400 million in venture capital, why he believes founders should think about expanding rather than pivoting, what it was like fundraising during the COVID-19 shutdown of live events, and why the company ultimately walked away from its planned SPAC. He also explains how founders can convince investors to back them against an entrenched incumbent, why your first hires define your company's future, and how AI is reshaping the future of live entertainment and ticketing. They get into: Why SeatGeek chose to compete with Ticketmaster and how investors evaluated that opportunity How SeatGeek survived COVID and closed its hardest fundraising round during the pandemic Why passionate customers can become your best fundraising asset The hiring mistakes Jack wishes he could undo and why your first employees shape company culture How AI is transforming ticketing, live entertainment, and the fan experience Jack Groetzinger's advice for founders building companies that challenge established incumbents Subscribe to Build Mode on⁠ Apple Podcasts⁠, ⁠Spotify⁠, or⁠ wherever you like to listen⁠.

  Nvidia's Sydney Sykes on Winning Corporate Venture Capital Deals 23.07.2026 43min

In this episode of Build Mode, host and Startup Battlefield lead Isabelle Johannesen sits down with Sydney Sykes, who leads global venture capital alliances and partnerships at Nvidia, to unpack how startups break into the Nvidia ecosystem and what a corporate venture capital partnership actually looks like once they're in.

  Diverse teams start with diverse VCs with Leah Solivan, Taskrabbit 02.04.2026 46min

  If 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. From bootstrapping TaskRabbit on credit cards to scaling it into one of the defining companies of the gig economy, Leah learned firsthand that the hardest part of building a company isn’t the product, it’s selecting the right people to build it. In this episode, Isabelle Johannessen and Leah unpack what it really takes to build diverse teams from day one and why most companies get it wrong by waiting too long. They also explore how the lack of diversity in venture capital directly shapes who gets funded, and ultimately, who gets hired. They discuss: How to build diverse teams intentionally from the very beginning Why the “easy path” in hiring leads to less diverse outcomes The connection between diverse VCs and diverse companies How to hire for culture and values over credentials Apply to Startup Battlefield: We are looking for early-stage companies that have an MVP.

  If 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 19.03.2026 48min

  Every 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.

First up is Hala Jalwan and Alessio Tresanti, the married co-founders of AI agent for procurement focusing on autonomous sourcing, Rivio.
