Interesting Facts & Summary
The Age of R&D Dominance
In the 2026 startup ecosystem, 'Deep Tech' has emerged as the absolute core. Unlike mature enterprises, these startups reinvest nearly all their revenue back into the lab.
- Biotech remains the champion of high-burn rates, as early-stage clinical trials and gene editing generate little revenue, leading to exceptionally high ratios.
- Quantum Computing and Nuclear Fusion often show ratios exceeding 100% of revenue, as their 'revenue' is largely grants or pre-orders, while R&D costs are immense.
- AI Safety and Ethics has entered the top 10 for the first time, reflecting the global market's urgent need for AI compliance.
