Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (3)

estimate_409a_valueread-onlyGives an indicative range for the fair market value per share of a US private company's common stock, as a planning estimate before a formal 409A valuation (for example, to anticipate an option strike price). Uses an option pricing model backsolve when there is a priced round in the last 12 months; otherwise a rolled-forward round, a sector revenue multiple, or an asset-based approach, depending on the inputs. Applies Finnerty and Chaffe marketability discounts. Inputs are numbers from the cap table and financials; no company or personal names are needed. Limitations: treats all preferred as non-participating and pari passu with 1:1 conversion, and does not model SAFEs or convertible notes. The result is not a 409A valuation.
estimate_emi_share_valueread-onlyGives an indicative range for the market value per ordinary share of a UK private company, as a planning estimate before agreeing an EMI valuation with HMRC (for example, to anticipate an EMI option exercise price). Uses the same methods as the 409A estimate, in pounds sterling: an option pricing model backsolve for a priced round in the last 12 months, otherwise a rolled-forward round, a sector revenue multiple, or an asset-based approach. Inputs are numbers from the shareholder register and accounts; no company or personal names are needed. Limitations: treats all preference shares as non-participating and pari passu, and does not model convertible instruments. The result is not an HMRC-agreed valuation.
get_formal_valuation_inforead-onlyLists the documents and typical steps for a formal US 409A valuation or UK EMI valuation, with contact details for Codon Valuation Advisors, the firm that provides this connector. Use when the user asks what a formal valuation requires or how to obtain one.
