Black and white portrait of Nathan.

In 2015, a visionary journey in the crypto markets began, led by a former global head of analytics and a partner at a top-tier consulting firm, Nathan Sage. Transitioning to a regulated fund manager, Nathan channeled his deep analytical acumen into algorithmic trading.

For a period of 3 years, we swiftly positioned ourselves at the forefront of the industry. By investing in cutting-edge technology and recruiting top industry talent, we enhanced our trading capabilities significantly.

In 2019, we disrupted the market norms by offering our institutional-grade algorithms to the general public. Our algorithms quickly reached customers in 75 countries in just 6 weeks and saw our trading volumes increase to excess of $1 billion daily.

Along this journey, we encountered significant hurdles for our own business. Our model relied on costly and often unreliable brokerage services that were inhibiting our ability to trade. This challenge catalysed our bold move to establish our own digital brokerage.

We’ve worked hard to develop our robust technology infrastructure and forged close-knit direct partnerships with the industry’s strongest market makers and clearing houses to manage borrowing, and execute both long and short positions in the crypto markets.

To 2023, we’ve handled billions in trades, offering reliable, low latency, minimal slippage and deep liquidity services to our network of clients. This has not only enhanced our operational efficiency but also significantly reduced costs that has granted us greater control over pricing for our clients.

Today, our integrated network of top-tier liquidity providers, lenders, settlement services, banks, and custodial solutions addresses the myriad challenges faced by digital asset market professionals. By offering the best prices, a broad selection of liquidity options, and comprehensive trading services through a single account, we provide our clients with unparalleled advantages in the cryptocurrency arena.

Capital Optimisation
Inside the Operating System.

Credit, margin, and yield deployed safely and efficiently across one unified balance.

Sage Capital Management was created to solve a structural failure in financial infrastructure.

Traditional frameworks force institutions to pre-fund multiple venues, lock collateral in isolated accounts and operate within disconnected margin systems. This restricts capital, slows execution and limits opportunity.

Sage replaces this with a unified capital engine powered by a network of institutional balance-sheet partners. Clients sign one capital agreement with Sage; behind the scenes, our system automatically routes credit in microseconds to the optimal capital provider for each trade.

This architecture gives institutions elastic capital capacity that expands during volatility and opportunity, instead of being constrained by a single provider.

Unified Portfolio Margin Across The Sage Network

Sage provides portfolio-level collateral management across all trading routed through the Sage network. Clients can hold assets centrally in fiat or digital form, and the combined portfolio value is available as margin for all supported products.

A single collateral pool across spot, derivatives, options and structured products

Real-time collateral valuation
Portfolio-level visibility of exposure and margin usage
Reduced pre-funding and more efficient capital deployment
Ring-fenced asset controls

Material capital efficiency while avoiding the risks of cross-margining between unrelated positions.

The Capital Network

A Network of Institutional Balance Sheets

Most prime brokers and lenders rely on their own balance sheet. Sage does not. Our capital engine sources liquidity from a distributed network of institutional balance sheets, ensuring that credit remains available when markets move.

This is capital as infrastructure, not a fixed pool of leverage.

Institutional Credit & Financing

Sage provides regulated, transparent and fully collateralised access to capital across the trading lifecycle. All credit is secured against assets held within the Sage network.

Over-collateralised financing based on portfolio value
Fiat liquidity borrowing secured by digital assets or fiat balances
Digital-asset secured credit
Structured financing aligned to institutional portfolios

Sage does not offer unsecured credit or uncollateralised lines. All capital is delivered through a risk-managed, collateral-backed framework that supports institutional-grade transparency and capital efficiency.

Real-time Risk and Collateral Management

The Sage capital engine continuously evaluates positions, collateral levels, exposures and liquidity conditions across all Sage-routed activity.

Institutions gain:

Real-time portfolio-level risk visibility
Automated thresholds and alerts
Transparent liquidation mechanics
Instant P&L and collateral updates
Integrated reporting across trading and financing

Risk becomes a single source of truth, not a fragmented patchwork across venues.

Capital that Expands With Opportunity

In fast-moving markets, capital constraints kill performance. Sage’s federated capital model provides capital elasticity. This means:

Credit remains available when other providers pull back during volatility
Your opportunity is not limited by a single balance sheet or risk appetite
You avoid delays associated with manual capital requests
You never need to split collateral across multiple platforms
