Horizon Technology Finance Provides $25 Million Loan Facility to Stellar Cyber

Key Terms

senior credit facility financial

A senior credit facility is a large loan or revolving line of credit that a company borrows from banks or lenders and that has first claim on the company’s cash and assets if the business runs into financial trouble. Think of it as the “first in line” debt with stronger repayment priority and usually stricter rules, so investors watch it because its size, cost and covenants affect a company’s cash flow, risk profile and the value of equity and other creditors.

growth capital financial

Growth capital is funding given to an already-operating company to help it expand—such as opening new locations, boosting production, or launching new products—without buying out current owners. Investors care because it aims to accelerate proven businesses to the next level: it can yield bigger returns than steady, mature companies but carries more risk, like putting fuel on a running car to make it go faster rather than building the car from scratch.

venture lending financial

Venture lending is a type of loan provided to young, privately held companies that have backing from venture capital investors; it supplies cash without forcing an immediate sale of ownership. Think of it like a targeted loan to a growth-stage startup that sits between a traditional bank loan and an equity investment — it matters to investors because it affects a company’s cash runway, dilution, and risk profile, influencing potential returns and the likelihood of future funding or exit outcomes.

managed security service providers technical

Managed security service providers are firms that businesses hire to run and monitor their cybersecurity day-to-day, much like contracting a professional security company to guard a building and watch its alarms. They handle tasks such as threat detection, incident response, and compliance reporting so companies don’t need deep in-house teams. Investors care because using these providers can lower the risk of costly breaches, smooth operating costs, and affect a company’s reputation and regulatory exposure.

security operations platform technical

A security operations platform is software that helps a company detect, investigate and respond to cyber threats across its digital systems, like a central alarm and incident response team for online risks. For investors, it matters because strong security operations reduce the chance of data breaches, downtime and regulatory fines—protecting revenue, reputation and the company’s value much like a good lock and alarm protect a storefront.

AI-native technical

A company or product described as ai-native is built from the ground up around artificial intelligence rather than having AI added on later; its core processes, user experience and decision-making rely on machine learning models and data pipelines. Like a house designed for wheelchair access versus one retrofitted, ai-native firms can move faster, scale more cheaply and offer unique products or cost advantages—information investors use to judge future growth potential and risk exposure to model, data or regulatory failures.

credit facility financial

A credit facility is a flexible loan arrangement that allows a borrower to access funds up to a set limit whenever needed, similar to a company having an overdraft option on a bank account. It matters to investors because it indicates how easily a business can secure cash when required, affecting its ability to manage expenses, invest, or respond to financial challenges.
