## Questions

### What type of companies does Advisory API Systems invest in?

The firm focuses on enterprise software companies that provide API-first infrastructure to the wealth management, asset management, and broader financial services industries. Target subsectors include portfolio management systems, compliance automation platforms, data aggregation middleware, and digital account-opening technology. The firm looks for companies where software replaces manual brokerage and advisory workflows.

### Does Advisory API Systems operate as a traditional venture capital fund?

No, the firm is structured as an asset manager rather than a conventional venture capital fund, though its investment activity spans venture-stage and growth-equity positions. The distinction lies in its continuous capital deployment model and its internal use of portfolio company technology. It does not appear to market discrete fund vehicles with fixed vintage-year timelines to external limited partners in the traditional manner.

### How does the firm source investment opportunities?

The firm's sourcing model is tied to its own operational use of portfolio company technology. By integrating portfolio company APIs into its own investment stack, Advisory API Systems gains operational data and network visibility that inform deal origination. This dogfooding approach creates a proprietary sourcing channel distinct from the intermediary-driven networks typical in growth equity.

### What is the geographic focus of Advisory API Systems?

The firm invests primarily in North America and, to a lesser extent, European markets where regulatory frameworks such as open banking mandate API interoperability. European exposure is concentrated in the United Kingdom and selected EU jurisdictions where financial infrastructure modernization is accelerating.
