Don't default to a 50/50 split on day one. Instead, agree to formally discuss equity only after reaching a predefined milestone, like $10,000 in revenue. This allows you to base the split on demonstrated contribution and commitment, avoiding the resentment from premature, misaligned agreements.

Don't give away half your company to a "business person" who handles administrative tasks. A non-technical co-founder must possess and execute on the most valuable skills in a SaaS business: sales and marketing. Otherwise, they don't deserve co-founder level equity.

When an experienced founder starts a new venture based on their own vision, the equity split doesn't need to be 50/50. By framing it as 'my deal,' the primary founder can retain a supermajority (e.g., 80%) while giving a technical co-founder a smaller but still meaningful stake.

Don't call someone joining your two-year-old, revenue-generating startup a "co-founder." They are a business partner joining a de-risked asset. Their equity stake should be far from 50/50, reflecting the significant value and progress you've already built, such as achieving initial product-market fit and revenue.

The founder's partnership allowed him to build a company without shouldering the initial financial risk. This "halfsies on risk" structure meant he never had true control or ownership, ultimately capping his upside and leaving him with nothing. To get the full reward, you must take the full risk.

A business transitions from a founder-dependent "practice" to a scalable "enterprise" only when the founder shares wealth and recognition. Failing to provide equity and public credit prevents attracting and retaining the talent needed for growth, as top performers will leave to become owners themselves.

The founder's number one piece of advice is to get the co-founder relationship right. While you can pivot ideas, raise more funding, or change markets, replacing a co-founder is incredibly difficult. A strong, complementary founding team is the foundation for overcoming all other startup challenges.

When you need to fill a major operational gap, hire for the role (e.g., a COO) before immediately seeking a co-founder and splitting equity. This allows you to "date before you marry"—assessing a candidate's impact and fit as an employee before committing to them as a long-term partner.

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.
