Product Lessons from KiwiCo: Scaling Physical Products, Toddler Feedback, and Manager Training

Sunlit makerspace classroom with a 'study box' spilling wooden gears and components onto a worktable, beside a toy robot and laptop; design diagrams and cogs fill the glass wall behind.

I sat down with Sandra Oh Lin, founder and CEO of KiwiCo, which creates hands-on learning kits for children. After executive roles at PayPal and eBay, she started KiwiCo over ten years ago to give her own kids more hands-on projects to exercise their creativity — a spark that led to entrepreneurship. Today, KiwiCo has expanded to include 8 different lines of crates that are shipped out monthly. As a product creator, I was eager to unpack how she turned a personal need into a scalable, beloved physical product line.

We dug into the thornier challenges of building physical products and her biggest aha moments as a first-time founder. She described creating the first KiwiCo crate — from the product development process to spinning up a supply chain and shipping department. We discussed how KiwiCo approaches new product lines, particularly in the last year when KiwiCo demand skyrocketed. She also shared how the team gathers quality consumer feedback when your customer is often a toddler — an audience that demands observational research, short feedback loops, and thoughtful proxies through parents and caregivers.

From a product discovery perspective, I found KiwiCo’s approach refreshingly pragmatic: iterative prototyping, tight learning cycles, and early validation that inform product roadmapping and sprint planning. When demand surges, operational excellence becomes a product feature — and Sandra’s experience reinforced that product-market fit lessons don’t end at the moment of traction; they expand into forecasting, inventory strategy, and resilience across partners. The throughline is an outcomes-over-output mindset that keeps the team anchored on value delivered to families rather than feature velocity.

We then shifted to culture — the often overlooked engine behind durable execution. Sandra is a strong believer in manager training for everyone, from folks that manage just one person to executives that have been managing for decades. She outlined the specific management training modules they leverage at KiwiCo and made the case for having everyone at the company fill out a motivations spreadsheet. For leaders navigating the IC to manager transition, these guardrails accelerate consistency, empathy, and decision quality across teams.

Finally, we explored how she creates a feedback-rich environment for herself as a CEO. I appreciated the intentionality — structured forums, explicit invitations for critique, and clear norms that make feedback safer and more actionable. Whether you’re shipping crates or software, the lesson holds: sustained product management leadership depends on mechanisms that convert diverse signals into aligned action. If you’re building physical products or scaling a product organization, these practices offer a blueprint for learning faster, de-risking complexity, and keeping customers — even the tiniest ones — at the center.
