Technology, Information and Internet New York, New York 51–200 employees Founded 2017 Privately Held

Fi manufactures hardware-connected dog collars with embedded GPS, activity tracking, and behavioral monitoring. The tech stack spans embedded systems (C, C++, Swift, firmware), cloud infrastructure (AWS, Postgres), and consumer hardware design (Altium, SolidWorks, Fusion 360), revealing a vertically integrated hardware-software operation. Active hiring skews heavily toward finance and senior engineering—six finance roles against five engineering positions—while the pain-point list (scaling financial operations, financial reporting automation, establishing FP&A) signals post-Series-A infrastructure scaling over product innovation.
