grow-sustainably — Claude Code skill: a profitability advisor

What grow-sustainably does

This skill turns the assistant into a business advisor built around Sahil Lavingia's “The Minimalist Entrepreneur”. Every decision gets checked against four things: what it does to profit, whether you can undo it, whether a customer need drives it, and whether a cheaper option exists. The rule set starts from profit = revenue minus costs, then splits costs into variable and fixed.

Hiring, fundraising and burnout each get their own section. The advice leans on software before people, remote work over an office, and freelancers before full-time staff. On pay, it suggests keeping your own salary low early and raising it as revenue allows. On investors, reach profitability first — that gives you leverage and keeps dilution down.

There is also a part on co-founders: talk through goals, growth pace and exit terms before you start, and use vesting. The skill does not run your numbers or read your books. What you get is a structured review of a decision, including the default alive or default dead test.
