No need for IT

With Brydge, there's no need for direct device LTE or WiFi connectivity, which thereby eliminates the technical complexity, OpEx and downtime constraints that plague traditional IoT architectures. Finally... no more headaches.

Get started

Rapid sessions

Brydge creates pre-authenticated tokens (think of them as keys) that sit in users' phones. When users interact, there's no cloud communication round-trip necessary, instead the device simply accepts and validates the token to start the session.

Encrypted data security

By default, Brydge's communication shuttle uses encrypted time-bound tokens and distributed data ledgers. Plus, its multi-hop architecture is never directly connected to the cloud, circumventing IoT's most common attack vectors.

"Just started my hardware learning journey and discovered the Brydge IoT Discord community! It's such an amazing space for everyone, from novices to enthusiasts. Can't wait to learn, share, and grow with fellow hardware lovers!"

Ania K.

Founder of Code with Ania

"We used another company first. It was what we thought to be good connectivity, then none of their chargers worked. We invested tens of thousands of dollars in IT infrastructure and the chargers still failed. We then installed [Brydge] and had zero issues, and have since expanded across our portfolio."

What's Brydge?

It is an IoT protocol that enables interactive smart devices powered by token-ledger short range communication to leverage all of the benefits of the cloud, without being directly connected to the cloud. We do this by embedding distributed ledger technology into smartphones and smart devices (via mobile servers) to compute smart functions hyper-locally across multiple nodes, rather than externally dependent on a single point of failure.

How does it work?

It utilizes mobile apps as ‘local-servers’ and ‘mobile hubs’ to operate all critical smart functions without connection to cloud or internet, while  also serving as a communication layer enabling complex operations typically reserved only for directly connected devices via cloud server, like access control, instant configuration updates, payments, and more. Under the hood, the protocol is powered by a proprietary cryptographic token-based protocol and distributed ledger system that's lightweight, crazy fast, and 100% secure.

What type of apps is Brydge best for?

It is built for mobile-first IoT applications that require features like authentication, access control (sharing), configuration updates, event monitoring, OTA updates, and more. In other words, it is an optimal IoT infrastructure solution for consumer, personal, industrial, and marketplace/sharing use cases that include mobile apps and/or need smart device to have authentication, payments, and/or data for the device fleet owner/operator.

What is Brydge NOT best for?

What type of applications is the technology NOT best for? Devices that don’t work with mobile apps and don’t have consumer interactions. Devices that don’t require any of the following smart functions: payment, authentication, diagnostics, OTA.

50x faster connection

WiFi/Cellular – requires a stable internet connection between the IoT device, cloud backend, and mobile phone. This involves roundtrip movement from the phone to the cell booster to antenna to cloud to ISP to router to IoT device and all the way back to just start an interaction.

Brydge – a user arrives at the IoT device with pre-authenticated encrypted tokens (think of them as end-to-end encrypted ‘keys’) already in their phone and refreshed frequently. When they begin an interaction via distributed ledger short-range communication between the phone and IoT device, there is no round-trip communication to the cloud, as the device interacts as a local server and simply accepts and validates the token (key) and starts the interaction. This process is up to 50x faster compared to using traditional WiFi/cellular architecture. This is not only a short-range communication benefit, so much as the value of Brydge and its encrypted tokens that act as a rapid authentication mechanism for devices (regardless of online or offline status).

Self-reliant computing (no cloud dependency, no IT, zero IT upgrades)

WiFi/Cellular/Ethernet – when deploying devices with typical cloud-dependent architecture that relies on these elements, you may have to deploy extra WiFi repeaters or set up your own network for security, as the customer may even require that. This is labor-intensive and requires materials to support, as well as ongoing costs to maintain the network. The same principle applies with ethernet (more costly and more reliable but not bullet-proof) and cellular becomes more expensive with cell boosters if there’s no cell signal or poor connectivity in the area – both the IoT device and the user’s phone require a strong, synchronous connection to make interactions work, while external factors like payment providers, cloud server, bank connection, and telecom provider all need to be connecting at same time.

Brydge – this architecture eliminates the need for any cloud or external dependency for critical smart functions, which eliminates need to communicate to the cloud (no IT infrastructure or upgrades whatsoever) by making leveraging proprietary distributed token-ledger technology as a self-reliant computing layer that turns the mobile smartphones and smart devices into hyper-local computing network. Brydge’s ledger-enabled smartphone mobile app also serves as gateway to the cloud. Brydge can also serve as value-add solution with Wi-Fi/Cellular smart devices to enable 100% uptime for critical smart functions, while enabling additional smart functions. Short-range communication is like a remote turning on a TV, but it can’t authenticate new users, payments, or OTA. It’s Brydge’s proprietary system that unlocks the smart devices to become super-computers as the tokens within app enable payment and price changes, access control and user authentication, and its distributed ledger technology works across all devices to bring data back from these devices for faster processing (no round trip needed). Any user that interacts with the device can do so with zero dependency, while still having the ability to transport data and leverage cloud without reliability issues.

100% uptime

Typical IoT – within the required round trip of information exchange, any broken piece, latency or constraints will lead to downtime during user authentication to start device, payments, reliable data exchange, and health check of a device.

– none of those failure points exist nor does any need for reliable connectivity or external cloud server to make smart devices “smart”. Brydge's ability to turn smart devices into independently-run supercomputers  = no downtime = 100% uptime.

Deployable anywhere

Typical IoT – without Brydge, you need to consider where connectivity is good/reliable and extend networks to areas in which the IoT devices are deployed, or avoid them altogether. This is restrictive and inflexible as some locations may be better from an optics/usability standpoint and/or cost perspective but you are blocked by these chains of connectivity.

– excels in every environment with or without connection to cloud. You can deploy devices faster anywhere you want or need them. Unlock 100% uptime for current connected environments, while expanding faster in all markets.

Cheaper and easier hardware

Lower costs of BLE components.

Lower power usage of BLE (less battery or power constraints so you can make your devices smaller or unlock new spaces).

Lower lead times as it’s easier to rely on the supply chains & intelligence of smartphones (backed by Apple/Samsung) over your own supply chain for the devices and the peripheral gateways needed.

Less risk of hardware redundancy if your technology evolves with smartphones and the apps/backend carriers just as much of the logic.

Reduced operating expenses

Typical IoT – with cellular you have to pay ongoing cellular SIM payments that can be restrictive to specific locations/geographies and result in higher recurring operating expenses. These may go as far as to outweigh the benefits unlocked and/or revenue generated from your smart devices in certain markets. WiFi-enabled solutions are typically limited to indoor environments and require ongoing maintenance to support the IT infrastructure.

– eliminates all the above. There are no operating expenses related to connectivity. This means no need for upgrades, and if you already have IT/WiFi then greater bandwidth/speed for devices’ non-critical smart functions.

Enhanced security

Typical IoT – with the devices directly connected to the cloud, they’re more susceptible to hacks and man-in-the-middle attacks (i.e. the most common IoT attack vectors).

– significantly enhanced security due to the multi-hop nature of the encrypted token and ledger architecture, which is also not directly connected to the cloud, and its inherently encrypted token-based data transmission.

Minimal technical complexity

Typical IoT - 12-18 months development process with 75% of projects failing at the pilot stage because things break.

- deploy in weeks, not months. Brydge makes it simple by completely removing the pieces prone to breaking in traditional IoT applications.
