Overview

A production-grade Python library for startup valuation, implementing every formula from the Startup Valuation textbook by Simon Mak (Valuation in Practice Series, Ascent Partners). Designed for developers, financial analysts, and AI agents who need auditable, structured valuation computations.

Three-layer architecture:

1. Python Library — 14 modules, 80+ typed functions, all returning ValuationResult (value + assumptions + sensitivity)
2. MCP Server — 14 folded tools (80+ formulas) for AI agents via stdio and hosted Streamable HTTP
3. AI-agent skills — 6 skill definitions with workflow guidance for valuation domains

Installation

pip install startup-valuation          # library onlypip install startup-valuation[mcp]     # + MCP serverpip install startup-valuation[dev]     # + pytest, ruff, mypy

Quick Start

Python Library

from startup_valuation.core import scorecard_valuation, vc_method_post_moneyfrom startup_valuation.advanced import black_scholes, scenario_analysisfrom startup_valuation.types import Scenario
# Scorecard Method (pre-revenue startups)result = scorecard_valuation(    average_valuation=1_500_000,    weights=[0.30, 0.25, 0.15, 0.10, 0.10, 0.05, 0.05],    scores=[1.25, 1.50, 1.20, 0.75, 1.00, 0.90, 1.00],)print(f"Scorecard: ${result.value:,.0f}")  # $1,800,000
# Black-Scholes for real options (startup equity)result = black_scholes(    underlying=20_000_000, strike=5_000_000,    risk_free_rate=0.05, volatility=0.40, time_to_maturity=1.0,)print(f"Option value: ${result.value:,.0f}")  # $15,240,000
# Scenario Analysisscenarios = [    Scenario("bull", 0.20, 10_000_000),    Scenario("base", 0.60, 5_000_000),    Scenario("bear", 0.20, 1_000_000),]result = scenario_analysis(scenarios)print(f"Expected value: ${result.value:,.0f}")  # $5,200,000

MCP Server (for AI Agents)

The server exposes 14 tools, each folding a family of formulas behind a method argument — probability, time value, CAPM, core pre-revenue methods, options, comparables, SaaS, marketplaces, fintech, biotech, hardware, international, stakeholder equity, emerging methods, and a triangulated full analysis.

Local (stdio):

pip install "startup-valuation[mcp]"startup-valuation-mcp          # console script installed with the [mcp] extra
**Prompts and resources.** Besides the 14 tools, the server offers three guidedprompts (`value_pre_revenue_startup`, `value_saas_startup`, `model_funding_round`)and a machine-readable method catalog at `startup-valuation://methods`, so agentscan see every method's required parameters before calling a tool.
# or: python -m startup_valuation.mcp# or ephemeral, no clone: uvx --from startup-valuation startup-valuation-mcp

Hosted (Streamable HTTP) — no install, no API key:

https://startup-valuation.simonmak.com/api

OpenCode — add to opencode.json:

"startup-valuation": {  "type": "remote",  "url": "https://startup-valuation.simonmak.com/api",  "timeout": 60000}

Claude Desktop / Cursor — add the HTTP URL https://startup-valuation.simonmak.com/api as an MCP server, or run the stdio entrypoint above.

MCP Registry — published as io.github.simonmak-ascent/startup-valuation (manifest: server.json) and listed on Glama and the Official MCP Registry. The glama.json file holds the Glama maintainer entry.
