As a founder, you lack time for constant pair programming. Your first engineering hire must be temperamentally suited to working alone. Screen specifically for individuals who excel in autonomous environments, not just those who are accustomed to constant team collaboration.

Claiming to be a perfectionist sounds noble, but it's a trap. Since perfection is unattainable, it provides a permanent excuse for not finishing your work. Professionals focus on quality, which simply means meeting the pre-defined specifications for the project.

Aspiring founders should resist starting a company until they've experienced multiple full project cycles, from messy conception to messy deployment. This repetition builds an invaluable intuition for timelines, processes, and what 'good' looks like, a crucial foundation for setting credible goals and leading a team.

Early-stage startups thrive on rapid iteration. Seek hires who can 'get shit done at an incredible clip' and make decisions at '100 miles per hour,' even if some are wrong. These individuals, often 'rough around the edges,' are more valuable than candidates with perfect paper pedigrees from large tech companies.

The ideal early startup employee has an extreme bias for action and high agency. They identify problems and execute solutions without needing approvals, and they aren't afraid to fail. This contrasts sharply with candidates from structured environments like consulting, who are often more calculated and risk-averse.

Spacium prioritizes hiring engineers who are obsessed with the mission and embrace a demanding work ethic, not just those with the best technical skills. This focus on a specific mindset is crucial for maintaining the speed and lean culture required for ambitious deep tech ventures.

When hiring your first developer, make prior experience at a small company (e.g., sub-50 employees) a mandatory criterion. The mindset, processes, and pace are so different from a large corporation that the cultural shock and re-training effort are too costly for a lean startup.

To scale a high-performing product team, hire individuals who exhibit the same level of ownership and love for the product as the original founders. This means prioritizing a blend of deep curiosity, leadership potential, and an unwavering commitment to execution over a simple skills checklist.

Working as a developer reveals the spectrum between sloppy work and over-engineered "gold plating." Learning to judge the appropriate level of quality based on context (e.g., five internal users vs. 10,000 public users) is a vital skill for founders operating with finite time and resources.
