Government Software

By Harj Taggar

Government processes are notoriously outdated, but the opportunity to modernize them is enormous. Palantir’s $125 billion valuation proves the market's potential. With AI capable of automating tasks like form-filling and document review, there’s a massive opportunity to cut government spending and improve efficiency. Imagine a world where a trip to the DMV is no longer a hassle.

While breaking into this space is challenging, the rewards for both builders and society are immense.

Public Safety Technology

By Garry Tan

Safety is a fundamental right, and technology can enhance it dramatically. Startups like Flock Safety are already solving 10% of crimes in the U.S., and tools like Abel Police free up officers for real police work.

Opportunities for builders include:

  • Advanced Computer Vision: Detect safety risks while maintaining privacy.

  • Emergency Response Enhancements: Improve coordination and speed.

  • Community Safety Tools: Strengthen neighborhoods through technology.

  • Law Enforcement Efficiency: Optimize operations for fairness and accuracy.

If you have ideas in this space, the potential to make a real difference is enormous.

Manufacture in the USA

By Jared Friedman

The resurgence of American manufacturing isn’t just about economics—it’s about reclaiming a global leadership position. Advances in robotics and machine learning have reduced labor costs, making it feasible to bring production back home.

Startups like Gecko Robotics and Astranis prove it’s possible to build world-class manufacturing companies right here in the U.S. If you’re ready to follow in Tesla’s footsteps, this is your moment.

Stablecoins 2.0

By Brad Flora and Harj Taggar
