What investors look for in today’s Series A market

The market for Series A—defined as an early-stage venture capital financing round—has undergone a structural shift. According to Thomas Krane, a managing director at the venture capital firm Insight Partners, fewer funding rounds are occurring, but the size of the deals has increased. This environment places a premium on long-term viability over initial momentum, meaning that while fewer startups are successfully raising capital, those that do are securing larger sums. Katie Stanton, an investor at the venture capital firm Moxxie Ventures, observed that “It has never been easier to start a company, and it has never been harder to build something that is defensible.” While starting a business has become highly accessible, establishing a defensible market position remains a significant hurdle for early-stage founders.

This shift means that not all businesses are suited for traditional venture funding. Krane cautioned that most companies should not pursue venture-scale growth, which refers to growth potential suitable for venture capital investment. Specifically, Krane noted that founders should avoid taking hundreds of millions of dollars in capital if they are not pursuing venture-scale growth. He explained that taking this capital is only worthwhile if founders believe they can build a very large business, highlighting the misalignment that occurs when standard businesses take on the high-growth expectations of venture capital firms.

To secure a Series A round in this selective environment, founders must prove their operational execution. Stanton emphasized that startups must demonstrate that they can repeatedly sell and grow in expanding markets. Beyond these commercial metrics, investors still look for intrinsic founder qualities to navigate long-term challenges. Sangeen Zeb, an investor at the venture capital firm GV, noted that passion is still the most important quality in a founder, identifying it as a critical indicator of long-term success. This suggests that even as metrics become more stringent, the human element remains central to investment decisions.

Why it matters

As the AI boom reshapes the venture landscape, Series A fundraising has become more selective; founders must now prioritize defensibility and clear growth metrics over simple startup creation.
