Episode Spotlight ✨: Investment Banker Turned Founder of Billion Dollar Fintech - Stash.
In this episode of the Startup Leap podcast, we speak to Ed Robinson, Co-Founder of Stash—a fintech platform empowering over 6 million customers and disrupting the traditional investing space.
Ed shares how Stash built customer trust in a regulated space, managed co-founder dynamics and raised initial funding. Plus, he talks about being featured as Apple’s App of the Day back in 2014—Yvonne even recalls seeing Stash go viral on Instagram in 2015 (back when "viral" wasn’t even a thing!) and Maria talks about the intricacies of building the MVP of a regulated fintech (licensing and partnerships) given her time building a digital bank.
If you're a founder looking to build in the fintech space, this episode is packed with practical insights to help you grow and scale your startup.
In this episode, we cover:
Key takeaways:
💡 Product to Market, Fast: From idea to beta in just 4 months. Ed's north star was speed, building a waitlist, the MVP, partnering with regulated partners and growth hacking to keeping momentum. Quick execution was key.
🎯 Milestones and Capital: Ed emphasises the importance of setting clear milestones and ensuring you have capital and runway before scaling up. It’s all about timing and preparation.
🔄 Iterate to Unlock Growth: Stash’s growth didn’t happen overnight. By continuously refining their onboarding process — like adding a “remind me later” feature to the app to skip high touch KYC requirements till users have to —they boosted conversions and solved metric challenges.
