The numbers behind a startup are a language of their own. We help you read it.
sunmarirs explains startup economics in plain terms — funding rounds, unit economics, burn rate, growth models and the decisions that separate viable companies from good ideas. No pitch, no products for sale, only clear explanations.
Economics, explained the way a founder actually needs it
Every article on sunmarirs is written to be understood without a finance background, while staying precise enough to be useful once the spreadsheets come out.
Funding & Capital Structure
How pre-seed through Series rounds work, what dilution really means, and how term sheets shape ownership over time.
Unit Economics
Customer acquisition cost, lifetime value, contribution margin — the ratios that tell you whether growth is healthy or borrowed.
Growth & Runway
Burn multiples, runway planning and the trade-offs between growing fast and growing sustainably.
Economics education, without the sales pitch
Founders are often taught the language of startups by the same people who benefit from them raising money quickly. sunmarirs was built as a neutral, independent reference: no courses to buy, no advisory retainers, no affiliate incentives — just structured, well-sourced explanations of how the underlying economics actually work.
We publish and periodically revise plain-language guides, glossaries and worked examples, aimed at founders, students and early employees who want to understand the mechanics before they are in the room where the decision gets made.

Structured reading paths, not paywalled courses
Rather than selling a curriculum, we organise our material into reading paths you can follow in any order — from first-principles definitions to more advanced modelling concepts.
