3Si has several investment vehicles in order to provide early-stage startups with access to capital. From venture debt, convertible notes, lines of credit (LOC) to equity financing, 3Si is here to handle the hurdle of finding capital.


Venture debt, venture lending or venture leasing is a type of debt financing provided to companies to fund working capital or capital expenses, such as purchasing equipment.  Unlike traditional bank lending, venture debt is available to startups and growth companies that do not have positive cash flow or significant assets to use as collateral.  Venture debt providers combine their loans with warrants or rights to purchase equity, to compensate for the higher risk of default.



A convertible note is an investment vehicle often used by seed investors investing in startups who wish to delay establishing a valuation for that startup until a later round of funding or milestone. Convertible notes are structured as loans with the intention of converting to equity.



A line of credit (LOC) is an arrangement between our funders and your startup that establishes a maximum loan balance that our funders will permit the startup to maintain.

Your startup can draw down on the line of credit at any time, as long the company does not exceed the maximum set in the agreement set forth by our funders.


The advantage of a line of credit over a regular loan is that interest is not usually charged on the part of the line of credit that is unused, and your startup can draw on the line of credit at any time that the company needs to.



Equity financing is the method of raising capital by selling company stock to investors. In return for the investment, the shareholders receive ownership interests in the company.
