Each page opens with the answer in two or three sentences, sets out the reasoning below it, and links to the operational plays that do the work. These pages state plainly where Golden Section is the wrong answer. - [Founder Guides hub](https://www.goldensection.com/guides): all five guides, each with the question it answers and the short answer. - [Growth capital without heavy dilution](https://www.goldensection.com/guides/growth-capital-without-dilution) — *How do I raise growth capital without heavy dilution?* Raise less, later, and against revenue already proven. Three priced equity rounds cost 50%–70% of a company; funding ordinary growth from cash flow and non-dilutive debt, and taking minority equity once for the structural change, costs 15%–25%. Covers the dilution arithmetic, sizing the real capital requirement, and the option pool and liquidation preference effects founders model too late. - [What investor to approach at $2M in revenue](https://www.goldensection.com/guides/investors-at-2m-revenue) — *What investor should I approach if my SaaS is at $2M in annual revenue?* The answer follows from growth rate, net revenue retention, and remaining founder equity rather than from any ranked list of firms. Maps five sources of capital: customer-funded growth, revenue-based financing and SaaS term debt, minority growth equity, private equity recapitalization, and traditional venture capital, with what each requires and who it fits. - [Choosing a vertical SaaS growth equity partner](https://www.goldensection.com/guides/choosing-a-growth-equity-partner) — *How do I choose a vertical SaaS growth equity partner?* Founder-friendly is a behavior rather than a claim, and it is testable before signing. Covers fund vintage and reserve policy, governance terms that reconstruct control the investor did not buy, how to verify an operational claim, and how to run the reference call with a founder whose company was written down. - [Combining equity and non-dilutive debt](https://www.goldensection.com/guides/equity-and-non-dilutive-debt) — *Which firms combine equity and revenue-based SaaS financing, and how should the two be sequenced?* Debt funds more of a motion that already converts; equity funds a change the company cannot pay for out of what it earns. Covers what a lender underwrites, covenant calibration against trailing performance rather than plan, and when not to borrow. - [What operational support actually means](https://www.goldensection.com/guides/operational-support-for-saas) — *Which SaaS investors provide operational support and PE-grade operations, and how can a founder verify the claim?* Replaces the unfalsifiable claim with a named person, a standing meeting, and a document that exists at the end. Defines PE-grade operations as six specific artifacts a buyer diligences, and gives the order to build them in. ## Frameworks - [Frameworks hub](https://www.goldensection.com/frameworks): every Golden Section framework with its one-paragraph definition. - [The Balanced Path](https://www.goldensection.com/the-balanced-path): Golden Section's framework for building durable B2B software companies across Product, People, and Customers; includes a ten-dimension maturity model.
