RemieDog founder Paul Vizzio was quoted $15,000 for a die-cast tool by his general suppliers. By finding a factory that specialized in small, niche die-cast components, he reduced the tooling cost to just $700, making the project financially viable.

Founder Paul Vizzio initially optimized a CNC-machined part from $45 to $25. To hit a consumer price point, he redesigned it for die casting and found a specialized supplier, dropping the cost to ~$2.50. This enabled a viable business model.

When sourcing manufacturers, Paul Vizzio prioritizes those who offer design feedback and work collaboratively. He finds this relationship is more valuable than securing the absolute lowest price, as it leads to a better, more manufacturable final product.

For early R&D, don't waste time designing custom components in CAD. Instead, buy existing products, tear them apart, and reuse their mechanisms. A simple tape measure can serve as a constant force spring, saving hours or days of design work and getting to a proof-of-concept faster.

Instead of trying to invent everything in-house, HOKA's founders understood that in the footwear industry, the true innovators are often the materials suppliers. They leveraged deep relationships to convince foam manufacturers to create a new, softer material that hadn't been done before.

Coop strategically sacrificed short-term profit by paying up to $5 per pound for foam when the industry standard was $0.50. This decision, enabled by running a lean team, allowed them to create a demonstrably better product. The investment in quality built brand equity and paid off as they scaled.

Figure designs nearly every component of its robots in-house, from motors to batteries. This extreme vertical integration, though costly upfront, prevents being at the mercy of third-party vendor timelines, code problems, or supply chain issues, enabling faster iteration and deeper system control.

Paranoid about quality control with their first Alibaba supplier, Unbound Merino's founders flew to the factory for the initial production run. This seemingly inefficient act of being physically present built a strong personal relationship that became their primary safeguard for quality.

Building custom components for early-stage prototypes is slow and expensive. A faster, more cost-effective approach is to buy existing commercial products that contain similar components, then scavenge those parts for your prototype. This enables rapid concept validation without investing in custom design and manufacturing.
