When a startup shows the potential for considerable growth, it may gain the attention of venture capitalists. VCs may be investment banks, wealthy individuals, or other firms looking to earn a high return on investment by supporting an early-stage company.

Entrepreneurs seeking VC funding must first find a source of venture capital and submit a proposal, including a business plan demonstrating the growth potential of the company. If a VC agrees to invest in the company, an agreement is made where the funds are provided in exchange for an equity stake in the company.

Along with the equity, the VC will typically take an active role in company affairs such as providing advisory service. Additional funding may be provided at a further date. The VC exits the company some years later, either by cashing out their equity or taking a share of the proceeds when the company is sold or acquired.

This article explores the different kinds of VC investments available to entrepreneurs. We also look at some VC firms that cater to Connecticut businesses.

Note: VCs typically limit their investments to specific endeavors and only finance a fraction of the requests they receive. If your business is not a good fit for VC funding, you can learn about other financing options here.


There are four stages of startup funding. Entrepreneurs can begin making a pitch for financing before they even begin operations, collect funding to develop their idea and expand their offerings, and ultimately choose to go public. 

Pre-Seed Funding

In this stage, an entrepreneur must convince investors that they have a profitable business idea and that they, along with any partners or team members, are well-situated to develop it. This is the riskiest stage for investors, as the business has not been developed and an entrepreneur will lack the performance data, financial information, or other metrics to help make their case.

Entrepreneurs often seek pre-seed funding not only from VCs, but also from angel investors, family members, and friends.

Seed Funding

After raising pre-seed funding, entrepreneurs continue fundraising efforts to support market testing, product developments, and other efforts to prepare products for sale or get services ready for marketing.

At this stage, investors will be looking at the company’s operations to see how well it can solve a need and reach a market. Naturally, there is still a considerable risk at this point, as the business may not be gaining traction. Ideally, seed funding will accompany the development of a client base, sales growth, or other signs that revenues are growing and the company’s offerings are finding customers.

Series Funding

Series funding involves several tiers of funding for startups to raise more money and increase their valuation. While the company remains private, each series provides further assurance that the business is generating consistent revenues and seeing growing demand. At this point, the risk is significantly reduced and the company will become more attractive to private equity firms and investment bankers.

Initial Public Offering

A company can choose to go public through an initial public offering once it becomes large and stable enough. A successful IPO will be profitable for investors and further bolster a company’s reputation.

Investors can exit the company through an IPO as well as a sale, merger, or acquisition. Entrepreneurs that can make it this far in the process often have several investors with a stake in their company, which reduces their own equity share but also yields a higher return due to the business’s greater value.
