Customer Problem
Large-scale BESS operators currently manage high-value assets as "black boxes" due to a lack of electrochemical transparency. Standard monitoring systems rely on imprecise software estimations, often resulting in State of Charge (SoC) errors of up to 20%. At this industrial scale, even minor inaccuracies in state-of-charge management lead to significant financial leakage and stranded capacity. This forces BESS operators to maintain massive, expensive energy safety buffers that underutilize capacity and degrade P&L, while leaving assets vulnerable to undetected safety risks like Thermal Runaway (TR). Business Model
DOYAM employs a hardware-enabled SaaS model specifically tailored for the BESS market, prioritizing tangible customer benefits such as immediate P&L improvement and significant enhancement of asset life. We deploy proprietary analytics & monitoring hardware directly into the storage infrastructure, paired with a recurring software subscription that delivers comprehensive battery intelligence.Technology Description
Our technology combines Online Electrochemical Impedance Spectroscopy (Online-EIS) with AI-driven software to create a comprehensive battery intelligence platform. We measure the "internal fingerprint" of battery cells during active operation, providing laboratory-grade accuracy for SoC, State of Health (SoH), and Remaining Useful Life (RUL). This high-fidelity data allows for unprecedented control over stationary storage assets by building an intelligence layer that does not exist in the market yet.Market Description
The utility-scale BESS market is entering a phase of exponential expansion, propelled by the global integration of renewable energy and the surging power requirements of massive data center infrastructures. As the sector matures, the landscape is shifting from early-stage arbitrage opportunities toward a more competitive and saturated environment where traditional revenue streams are narrowing. This evolution presents a significant challenge for operators: the need to transition from basic oversight to sophisticated analytics & monitoring. The market now demands a deeper level of electrochemical transparency to overcome the "black box" limitations of current assets. For stakeholders, the priority has shifted toward optimizing revenue performance and unlocking additional value from existing capacity, making high-fidelity data the essential requirement for navigating this increasingly complex and margin-sensitive market.USP
Our USP lies in the ability to fundamentally shift the economic profile of BESS operations by unlocking hidden P&L. By reducing State of Charge (SoC) error from the industry standard of 15-20% down to a precision of just 2%, we enable operators to safely minimize excessive energy buffers and maximize usable capacity. This high-fidelity insight directly translates into increased revenue through higher energy throughput and more aggressive participation in grid services without compromising asset integrity. Unlike software-only competitors who rely on secondary estimations and data modeling, our hardware-enabled analytics & monitoring identifies electrochemical anomalies at the source. This provides proactive prevention of Thermal Runaway (TR), extending State of Health (SoH) and Remaining Useful Life (RUL), ensuring that stationary storage assets remain bankable and high-performing throughout their entire lifecycle.
