Software systems for early‑stage companies.

FIG. 2 shows the v1 data ingest pipeline we built for GridIQ. GridIQ makes sensors 30 that mount on utility poles and watch power distribution lines 24 for faults. Power flows into the line from one end 22. When a fault 26 strikes, every sensor sends what it saw over a cellular uplink 32 to a broker 34. A sensor that saw fault current sits between the power source and the fault. A sensor that saw none sits past it. So each report that comes in narrows the span 28 where the fault can be. A stream 36 carries the readings on to a time-series store 38, which keeps them for analysis.

FIG. 3 shows a phone 44 counting stock on a shelf 40. The phone’s camera sees a field of view 46. Computer vision on the phone finds each product 42 in that view and adds it to that product’s count 48. Fall Guy engineers built this for Nomad Go, first as staff on the Nomad Go team and then with Patrick as CTO. It runs in more than 11,000 retail locations.

FIG. 4 shows Verantel 50, our own AI intake interviewer for law firms, now in private beta. Each person 56 who contacts a firm talks with Verantel on their own computer, in plain words and in their own language. Verantel asks one question at a time 52, and each answer shapes the next one: when an answer is vague or a point is missing, Verantel asks the follow-up. It stops when nothing is left unclear and hands the firm a thorough report 54, one for every person who comes 58. A firm can run it on its own server. Verantel is not a lawyer and gives no legal advice.

FIG. 5 shows augmented reality on a phone 60. The phone finds the top 64 of a real table 62 and stands a virtual figure 66 on it. The figure is drawn in phantom lines because it is not really there. On the phone’s screen it stands on the table, and it stays in place as the phone moves. From 2015 to 2022, Fall Guy engineers were embedded in the 5G lab at Verizon and Envrmnt. There they built a wide range of experimental AR and VR projects and apps.

FIG. 6 shows a shopper finding one item 76 in a large store 70 with the 3D indoor map engine we wrote for Point Inside. The phone 78 draws the store in 3D, aisles 72 and all, and plots the route 74 to the item. Target, Lowe’s, and Meijer used the engine in their store apps. One code base ran on both iOS and Android.

FIG. 7 shows Moai, the open-source game engine Patrick built as founding CTO of Zipline Games. A game written once on Moai runs on a phone 80, a tablet 82, and a desktop computer 84. Each one runs the same game 86, framed to fit its own screen. Moai was downloaded tens of millions of times. It ran Broken Age by Double Fine, Crimson: Steam Pirates by Harebrained Schemes, Eastward by Pixpil, and Elevate, Apple’s 2014 App of the Year.
