What Larch Networks does
Larch Networks is a privately-held Israeli systems-engineering company founded in 2009 and headquartered in Rosh Ha'ayin, with R&D centers including one in Kyiv, Ukraine. The company provides tailor-made network hardware and software development for hi-tech customers, specializing in open-networking technologies — most prominently SONiC (Software for Open Networking in the Cloud) and Marvell-based silicon platforms (AC3, AC5, AC5X, PN3, Ironman, Falcon, Aldrin, Teralynx). Larch is a Certified Marvell Partner with access to Marvell's ROS source code and also delivers Hardened SONiC NOS, the OpenROS extensible architecture, and a FastBoot custom NOS with sub-30-second boot time. The product portfolio spans industrial switches (DIN-rail and rack-mounted, -40 to +71°C, PoE+), data-center switches (10G through 800G, including Aldrin/Falcon/Teralynx/X2 lines), campus/access switches, network packet brokers (Orama X25N and Orama X400 at 400G), OpenLAN/TIP OLS-compliant switches, and Ironman-based network switch modules for Industry 4.0 and IoT.
The company serves telecom operators, data-center and cloud providers, enterprises, and industrial customers (aerospace, mining, rail, utilities, intelligent transportation), with named case-study experience across Fortune-500 ICT, mining operators, telecom operators, and aerospace/defense — most customer identities remain confidential. Revenue is generated through a mix of finished-hardware sales (including CKD/SKD kits and private-label/OEM arrangements), professional services for custom hardware and embedded software development, SONiC/SAI hardening and porting, Marvell systems consulting, and hardware production localization. The go-to-market combines direct enterprise sales, an Added Value Reseller (AVR) program, distribution via AVNET Silica, and technology partnerships with Marvell, IP Infusion, Dorado Software, PANTHEON.tech, Xsight Labs, Network Critical, Teledyne LeCroy, and Pegatron; the company also joined the SONiC Foundation under the Linux Foundation in August 2025. Larch is founder-controlled (CEO Alexander Cheskis, Co-Founder Inna Cheskis) with no institutional capital disclosed, an engineering-heavy workforce (90% engineers), a reported 50% year-over-year revenue increase, and 100+ clients served worldwide.
