Excelfore & the Car That Updates Itself
The Fremont software company most drivers have never heard of - quietly moving over-the-air updates and diagnostics through more than 17 million vehicles.
The Fremont software company most drivers have never heard of - quietly moving over-the-air updates and diagnostics through more than 17 million vehicles.
A modern car carries more code than a fighter jet and more small computers than most offices. The hard part is not building those systems - it is updating them safely, over the air, for a decade, while pulling diagnostics back out. Excelfore Corporation spent years solving exactly that unglamorous problem, and its answer is a platform called eSync.
eSync is a two-way street. It carries software updates into a vehicle - down to individual electronic control units - and it carries diagnostics and data back up to the cloud. Around that core, Excelfore builds in-vehicle networking stacks (Automotive Ethernet and Time-Sensitive Networking), a data-aggregation platform called eDatX with edge and generative AI, and a framework for activating and monetizing features after a car is sold.
The company's own tagline is plain about the job: SDVconnect - the power to connect the software-defined vehicle. It is infrastructure, not a consumer brand. When your car improves itself overnight, there is a real chance the update crossed an Excelfore pipeline before it ever appeared on your dashboard.
Enabling automakers to excel in an increasingly connected, software-driven world.
Full-vehicle over-the-air update platform delivering secure, bi-directional updates and diagnostics to any ECU or edge device, with delta compression to shrink data payloads.
Since ~2015Smart data-aggregation platform that collects, normalizes and analyzes in-vehicle and fleet data, with edge-AI and generative-AI for diagnostics and prediction.
Since ~2020Automotive Ethernet and TSN/AVB middleware - Excelfore fielded one of the first Avnu-certified Ethernet AVB stacks for automotive.
Since ~2013Framework for dynamically deploying, activating and monetizing vehicle features after the point of sale, turning updates into recurring revenue.
Since ~2021Real-time remote vehicle health monitoring and predictive maintenance built directly on the eSync data pipeline.
Since ~2018Co-founded industry association standardizing OTA and edge-device data connectivity - so the whole industry can interoperate, not just Excelfore.
Since ~2018Shrinath and Shrikant Acharya did this once before.
In the 1990s the brothers co-founded MARGI Systems, which pioneered the delivery of infotainment headunits and in-vehicle networking. MARGI was acquired by Harman - now part of Samsung. They could have stopped there. Instead they looked at the modern vehicle, saw dozens of computers that could not talk to the cloud, and started again.
Shrinath, the CEO, sets strategy and builds the automotive partnerships. Shrikant, the CTO, drives the technology roadmap. Between them sits roughly 25 years of continuous work on automotive networking - the kind of domain depth that is very hard for a newer entrant to fake.
Excelfore is a business-to-business company. Its customers are automotive OEMs and Tier-1 suppliers, and it sells through platform licensing, per-vehicle or per-device fees, and engineering integration work. Features-on-demand and data-monetization tooling add a recurring, lifecycle-based layer on top - revenue that keeps flowing after the car is on the road.
Reported adopters span the industry's range. FAW and JMC (for Ford and JMC vehicles in China) deployed eSync for OTA. In 2025, Hero MotoCorp - the world's largest maker of motorcycles and scooters - put eSync on next-generation two-wheelers now riding through more than ten Indian cities, using an integration with AWS IoT Core.
SDVconnect: the power to connect the software-defined vehicle.
Plenty of companies do over-the-air updates - Sibros, Aurora Labs, Airbiquity, HARMAN, and OEM in-house teams among them. Excelfore's distinguishing move was strategic: it built a strong product and then helped create the eSync Alliance so the whole industry could adopt a common standard. Owning a standard tends to outlast owning a single product.
The second differentiator is breadth. Excelfore does not stop at pushing updates. It sits across the in-vehicle network, the OTA pipeline, the data-aggregation layer, and the monetization framework - one vendor for the connective tissue rather than four. That depth traces directly back to the founders' decades in automotive networking.
Automotive suppliers Molex and HELLA Ventures both invested - a bet placed by the exact companies whose customers keep asking for OTA.
Integrations with AWS, Microsoft Azure (MCVP) and Google Cloud mean Excelfore rides whichever cloud an OEM already uses.
