The quest to create artificial intelligence as efficient as the human brain is one of computing's most fascinating challenges. While today's AI systems consume megawatts of power in massive data centers, your brain accomplishes far more complex tasks on roughly 20 watts—about the same as a dim light bulb. This efficiency gap is what FemtoSense is determined to close.

In this illuminating conversation with Sam from FemtoSense, we dive into the journey of this Stanford spin-off that's revolutionizing edge AI with neuromorphic-inspired computing. The company's very name speaks to their mission—"femto" references the femtojoule, the incredibly tiny amount of energy required for a single neuron in your brain to communicate with another. Their goal? Create AI systems that approach this remarkable biological efficiency.

What makes FemtoSense's approach unique is how they've evolved from pure academic research to commercial viability. Rather than pursuing neuromorphic computing in its purest form, they've distilled its key efficiency principles—sparse computing and spatial locality—into manufacturable, reliable systems. This pragmatic approach is already bearing fruit in consumer wearables like AI-powered hearing aids that maintain 24-hour battery life while delivering sophisticated audio processing, and in smart home devices that offer on-device intelligence without cloud dependence. For battery-powered devices, their technology extends runtime dramatically; for plugged-in devices, it slashes costs by reducing silicon footprint.

As Sam puts it, "Efficiency is the new currency." The principles that make FemtoSense's technology possible aren't tied to any specific market or modality—they represent fundamental improvements in how computing can be done. With global operations spanning the US, Asia, and Europe, and active participation in industry groups like the Edge AI Foundation, FemtoSense isn't just building more efficient chips; they're helping shape a future where AI can be everywhere without consuming the planet's resources.
