Our Tech Stack
The Grand Central Product Suite
The Grand Central product suite focuses on four main areas:
Data and aggregation
Payments
Origination and distribution
Portfolio monitoring
Grand Central Warehouse
Purpose
GCWarehouse is the foundational product within the GCSuite. It allows investment firms to quickly ingest a very broad variety of very granular borrower data, at scale, in a cost-effective way. This data can be easily extracted and moved onto any blockchain, using the off-the-shelf analytical tools developed by the Untapped Global Data Team. It is the core weapon in the arsenal needed to open new markets and remove blockers of new opportunities.
How it works
There is no combination of off-the-shelf technology that checks all three of these boxes: granularity of data, speed, and cost. As the complexity of the data increases, the risk of facing bottlenecks and runaway costs increases. GCWarehouse is designed to preempt these common threats. The product is powered by proprietary layers of technology or adaptations of existing ones, which ensures flexibility and speed during ingestion into a standardized, yet flexible and extensible data model, facilitating aggregation at portfolio level. Currently, the ingestion of each new source takes on average 48 hours.

Why it is different
GCWarehouse delivers unmatched scale, speed, and flexibility eliminating the need for sudden team expansion or costly tech overhauls when onboarding new borrowers, markets, or portfolios. Its modular architecture future-proofs infrastructure by adapting seamlessly to evolving business models and growth objectives.
Unlike conventional systems that rely on manual APIs, reactive data checks, and static dashboards, GCWarehouse employs a multi-modal plug-in framework (API, Database, and S3 integrations) with proactive data validation and dynamic analytics capabilities. This ensures real-time visibility, operational continuity, and intelligent scalability across all data pipelines turning integration from a bottleneck into a strategic advantage.
Grand Central Wallet
Purpose
GCWallet’s goal is seamless, 2-way connection between global investors and end borrowers, no matter how complex and fragmented the markets they operate in. In one direction, it facilitates capital allocation; in the other direction, it de-risks investments by drastically reducing the risk of end borrowers defaulting on their obligations.
How it works
GCWallet consists of a network of electronic payment streams, both within the fiat and crypto worlds. This allows global investors to get exposure to new opportunities in untapped markets without anything more complex than a USDc wallet or bank account. It removes multiple layers of operational complexity that would otherwise be required to invest in new markets.
Why it is different
GCWallet covers the distance at an unmatched speed: from the most vanilla tools, such as a USD bank account, all the way to new opportunities in the most difficult-to-reach markets.
Grand Central Underwriting & Syndication
Purpose
This is the main consumer of the on-chain data produced by GCWarehouse, on the pre-trade side of the workflow. It consists of two main blocks:
An underwriting engine computing a variety of proprietary metrics, including Risk Score;
A syndication engine which helps originators with pitching and marketing the unique insights produced by the GCWarehouse data.
How it works
It consists of layers of proprietary methodology—part of which is based directly on Untapped Global’s own direct experience as an originator and investor—applied to the data captured. It helps originators interpret and extract value from data and generates executable insights at both the due diligence and allocation level.
Why it is different
GC Underwriting & Syndication isn’t just a tech solution — it’s a practitioner-built platform that blends real-world experience with powerful infrastructure, built for professionals navigating the complexities of embedded finance in frontier markets.
Grand Central Monitoring & Analytics
Purpose
This is where the post-trade components of the GCSuite live. Their purposes include real-time monitoring of underlying assets as well as forecasting and benchmarking, which can be used by both originators and investors.
How it works
A set of analytics powered by real-time on-chain data, allowing risk managers to set alerts on their deals using a system of traffic lights. This drastically reduces the resources needed to monitor the portfolio and at the same time improves credit and investment outcomes. For investors, it provides real-time transparency on the performance.
Why it is different
Granularity, speed and traceability of data are the key differentiators. The data covers both the operational aspects of the RWAs and the payments that the asset users are generating. These are collected in near-real time and moved on chain to ensure total and instant transparency.
