Professional startup valuation — 5 methods, one dashboard
A production-grade web app for evaluating early-stage startups using five professional valuation methodologies. Built for venture capital and private equity analysis, with an intuitive interface that lets you compare methods side-by-side, visualize results, and export valuations instantly.
VentureVal implements five industry-standard methodologies used by VC/PE firms:
Pre-revenue valuation framework assigning value to five critical success factors:
- Sound Idea — Commercial potential of the concept
- Prototype — Reduction of technology risk
- Quality Management — Strength of the founding team
- Strategic Relationships — Market risk mitigation
- Product Rollout/Sales — Production and sales execution
Best for: Idea to prototype stage companies with no revenue.
Comparative approach adjusting regional median valuations based on six weighted factors:
- Management Team (25%)
- Size of Opportunity (20%)
- Technology/Product (18%)
- Competition/Marketing (25% combined)
- Financing/Exit Strategy (20% combined)
Best for: Pre-revenue startups in established markets with comparable deals.
Systematic risk assessment across twelve categories, adjusting a base valuation by -$500K to +$500K per factor:
- Management, Stage, Legislation, Manufacturing
- Sales/Marketing, Funding, Competition, Technology
- Litigation, International, Reputation, Exit Potential
Best for: Comprehensive risk-adjusted valuations at any stage.
Terminal value approach calculating maximum pre-money valuation based on:
- Projected exit value (revenue × industry multiple)
- Target return on investment (ROI)
- Years to liquidity event
Best for: Growth-stage companies with predictable revenue trajectories.
Market-based valuation using multiples from similar deals:
- Revenue multiples from comparable companies
- Stage, sector, and geography adjustments
- Median and range analysis
Best for: Companies in sectors with recent comparable financing activity.

VentureVal was developed as part of MBA 664: Venture Capital & Private Equity coursework at BYU's Marriott School of Business. While built for academic purposes, the implementation follows production software engineering standards:
- Type-safe architecture with comprehensive TypeScript interfaces
- Component-driven design for maintainability and reusability
- Professional UI/UX matching industry tools like PitchBook and Crunchbase
- Real-world methodologies used by top-tier VC/PE firms
The project demonstrates practical application of financial theory while showcasing modern web development capabilities. All valuation formulas are based on industry-standard frameworks taught in MBA finance curricula.
Learning Outcomes:
- Implementation of multiple valuation methodologies
- Data visualization for financial analysis
- Full-stack web application architecture
- Professional-grade software delivery
