With the Light Phone, Kaiwei Tang and Joe Hollier have spent over a decade exploring the value of simplicity in our relationship to technology, partnering along the way with players like Andrew Yang, Kendrick Lamar, and Pete Davidson. Now, with a new flip phone and a growing wave of “attention activists” pushing back against Big Tech, they think the rest of […]

Light co-founder Kaiwei Tang helped create the Motorola Razr, and he's as surprised as anyone that over 20 years later, the flip phone is relevant again.

The funding discussions point to investor interest in applying AI to make breakthroughs in life sciences.

Starliner's certification may be delayed to 2027, 10 years later than Boeing's original schedule.

These clever lights—each one an exemplar of innovation in materials, design, and function—will beautify your home.

Andrew Yang’s 2020 presidential campaign was based on a warning that automation and AI would hollow out the labor market and concentrate wealth in the hands of a few. At the time, ideas like Universal Basic Income felt fringe. Now Dario Amodei, Sam Altman, and Bernie Sanders are all saying versions of the same thing. An entrepreneur at heart, […]

Sandstone's Series A was led by Lightspeed Partners, with participation from Sequoia.

Smart Lighting Protocol Showdown: Zigbee vs Matter vs BLE Mesh (2026) After deploying thousands of Zigbee smart lights through our manufacturing line at nexLAMP, and watching countless customers struggle with protocol selection, I decided to write this practical comparison. The Real Problem "My smart lights keep disconnecting! I think I chose the wrong protocol..." This is the #1 complaint I see on Reddit, Xiaohongshu, and Zhihu. The fix isn't a better router — it's choosing the right protocol from day one. Protocol Deep Dive Zigbee — The Workhorse Frequency : 2.4 GHz (separate from WiFi) Topology : Star + Mesh hybrid Max devices : 200+ per coordinator Latency : 50-200ms Cost/unit : ~$3.5-5.0 (Tuya Zigbee drivers) Why it wins for lighting: Each node is a repeater → self-healing mesh Ultra-low power → years on coin cell for sensors Mature ecosystem → Tuya, Hue, Aqara, Xiaomi all ship Zigbee The catch: You need a Zigbee gateway (~$15-20). This is the only upfront cost. BLE Mesh — The Budget Option Frequency : 2.4 GHz (shared with WiFi/BLE) Topology : Managed flood mesh Max devices : ~50 (practical limit ~30) Latency : 100-500ms (increases with node count) Cost/unit : ~$2.0-3.5 The flooding problem: Every command is broadcast to every node. With N nodes, you get O(N²) message propagation. Past 30 devices, you'll notice visible lag. Good for: Small apartments (≤ 6 lights), budget projects. Matter — The Future Transport : Thread (preferred) or WiFi Topology : Thread mesh (similar to Zigbee) Max devices : 250+ (theoretical) Latency : 30-150ms (Thread), variable (WiFi) Cost/unit : ~$7.0-11.0 (currently higher) Matter's promise is genuine cross-platform control. But in 2026: Pros: Native HomeKit, Alexa, Google Home support Thread mesh is excellent (when it works) IP-based → easier cloud integration Cons: Thread Border Routers aren't ubiquitous yet Advanced lighting features still evolving Premium pricing for early adoption Cost Analysis (20-Fixture Deployment) Protocol Driv
