PROPRIETARY INTELLIGENCE

The Frontier Index™

Our proprietary scoring methodology built for frontier tech — the only index that weights government traction, defense contracts, and geopolitical positioning.

🎯 Frontier Index™ Methodology (v3.0)

Purpose-built for defense, space, energy, and deep tech. Unlike generic startup scores, we weight what actually matters in frontier markets:

25% Capital Momentum

Funding velocity, round size vs. sector median, investor quality tier, time since last raise

25% Government Traction

DoD/DoE contracts, SBIR/STTR awards, security clearances, prime contractor relationships

20% Technical Moat

TRL advancement rate, patent portfolio, ITAR/export control advantages, deep tech barriers

15% Operator DNA

Founder clearance level, defense/gov experience, technical depth, mafia network strength

15% Strategic Alignment

NDAA relevance, allied nation partnerships, critical supply chain position, regulatory tailwinds

👑 90+ Elite 🔥 80-89 Exceptional ⚡ 70-79 Strong 📈 60-69 Emerging

Scores updated weekly. Each assessment includes documented evidence, prior period comparison, and trend analysis.
