An independent reference for the economics behind startups
sunmarirs was created to explain how startups actually work financially — not to sell a course, a subscription or an advisory retainer. We are a small, editorially independent project based in Slovakia.
Why we exist
Most explanations of startup economics come attached to something being sold: a bootcamp, a fundraising deck template, a paid newsletter. We wanted a place where the concepts themselves — cap tables, burn rate, runway, unit economics, growth accounting — were explained clearly, sourced honestly, and kept up to date, without a checkout page anywhere in sight.
sunmarirs publishes written guides and reference material only. We do not offer paid courses, consulting, coaching or financial products of any kind, and nothing on this site should be read as an offer of such services.
Principles that guide what we publish
Independent by design
We accept no sponsorships tied to specific startups, funds or financial products, and we do not sell any service through this site.
Sourced and reviewed
Explanations are checked against public financial literature and revised periodically as terminology and market practice evolve.
Written to be understood
We favour plain language and worked examples over jargon, so material is useful to first-time founders and finance professionals alike.
Privacy-respecting
We collect the minimum data needed to operate the site. See our Privacy Policy for the specifics.
