Unbound Merino's founders reject the common wisdom that business and friendship don't mix. They argue it's an advantage because you start with baked-in trust and value alignment, making it easier and more enjoyable to navigate the inevitable challenges of building a company.

Non-technical founders can attract technical co-founders by first building a manual, non-scalable version of their product. This creates a user base of passionate early adopters who are mission-aligned. The ideal co-founder is often among these first users, as they have already demonstrated belief in the solution.

Spend significant time debating and mapping out a project's feasibility with a trusted group before starting to build. This internal stress-test is crucial for de-risking massive undertakings by ensuring there's a clear, plausible path to the end goal.

Technical competence is the easiest part of a technical co-founder to evaluate. The real risks lie in misaligned goals (lifestyle vs. unicorn), personality clashes, and incompatible work styles. Prioritize assessing these crucial "human" factors first.

To launch new products and compete with agile startups, embed a small "incubation seller" team directly within the technology organization. This model ensures tight alignment between product, engineering, and the first revenue-generating efforts, mirroring the cross-functional approach of an early-stage company.

The founders credit their successful partnership to an equal commitment to hard work. By dividing responsibilities and working independently before collaborating ('divide and conquer'), they ensure an even playing field and avoid the common pitfalls of co-founder burnout or resentment that often ruin business friendships.

A rising tide lifts all boats. The true test of a founder partnership emerges during downturns. Diligence should focus on teasing out traits like adaptability, humility, and accountability, which predict how a founder will react when plans inevitably go awry.

During its long, pre-revenue build, Runway couldn't rely on constant market feedback. Instead, they depended on the founder's "taste"—defined as knowing what's good without external validation. This internal conviction is crucial for ambitious products that aren't a "random walk" of testing.

Incubating a company with a proven internal employee who develops an idea, like Every did with Good Start Labs, is a superior model. It bypasses the adverse selection problem inherent in recruiting external founders for pre-formed ideas, as the founder's capabilities and commitment are already known quantities.
