Crunchbase’s latest U.S. seed funding figures offer compelling evidence that this perception is not merely anecdotal; it reflects a tangible shift in the market dynamics. The data reveals a significant bifurcation in seed trends, where the market is splitting into distinct segments with vastly different investment patterns. For instance, deal counts and the aggregate amounts invested in the pre-seed and regular seed funding range bands—specifically those encompassing deals from $200,000 to under $5 million—have experienced a notable decline, dropping roughly 20% year over year. While Crunchbase acknowledges that these proportions typically improve slightly over time as smaller seed rounds are progressively added to their database, the initial downturn indicates a clear trend. In stark contrast, the mid-tier band, covering investments from $5 million to under $10 million, demonstrated remarkable stability, remaining on par with the previous year’s activity.

However, the most striking growth within the U.S. seed funding landscape in 2025, according to Crunchbase data, was observed exclusively in the upper echelons of larger and outlier seed rounds—those deals valued at $10 million and above. This trend underscores a pivotal shift, where significant capital is increasingly flowing into a smaller number of highly promising, or perceived highly promising, early-stage ventures. Katie Stanton, the insightful founder of the seed fund Moxxie Ventures, succinctly captured the essence of this bifurcated market dynamic. "You’re either an AI elite team that is growing really fast and you’re going to raise a ton of capital at Series A from one of the big firms — or you’re everybody else," she articulated, highlighting the stark divide between a privileged few and the majority of startups. This sentiment reflects a market driven by a powerful "flight to quality" and an intense focus on emerging technological frontiers, particularly artificial intelligence.

In response to this rapidly evolving market, Moxxie Ventures, under Stanton’s leadership, has proactively recalibrated its investment strategy. Her fund has committed a greater proportion of its capital—between 60% and 70%—to primary investments, a significant increase from the 50% allocated in previous funds. This strategic pivot is driven by a desire for "more shots on goal," indicating a recognition that in a more competitive and capital-intensive environment, a broader portfolio of early-stage bets might be necessary to identify and back future winners. Furthermore, Moxxie Ventures has shifted its focus to identifying founders at an even earlier stage, often before they have achieved clear product-market fit. This proactive approach suggests a move towards higher-conviction, earlier-stage bets, where the potential for disruption and growth is perceived to be immense, justifying the increased risk associated with pre-product-market fit investments.

Delving deeper into seed deal counts, the data reveals a fundamental reshaping of the early-stage investment landscape. While the majority of seed-stage deal counts still occur for rounds valued at $5 million and under, the percentage represented by these smaller deals has steadily declined over time. In 2018, these rounds accounted for a substantial 93% of all seed deals. By 2025, this figure had dropped significantly to 75%, indicating a clear trend away from numerous small investments. Conversely, larger and outlier seed rounds, specifically those of $10 million and above, have seen a marked increase in their share of the total deal count. These high-value rounds climbed from a mere 2% in 2018 to a noteworthy 9% in 2025. This means that approximately one in ten seed deals exceeding $200,000 in 2025 was a substantial investment of $10 million or more, totaling around 360 such deals. This shift signifies a growing concentration of early-stage capital into fewer, albeit larger, investment opportunities, reflecting heightened investor confidence and potentially higher entry valuations for these select companies.

The aggregate seed amounts further underscore this dramatic reorientation of capital allocation. U.S. seed funding reached an impressive total of $19.4 billion in 2025, according to Crunchbase data. This robust total, however, was not evenly distributed across all deal sizes. Instead, it was predominantly driven by large deals, with seed deals of $10 million and over accounting for a staggering 51% of the total funding in 2025, a substantial jump from the one-third they represented in 2024. This concentration is vividly illustrated by the largest seed round of 2025: a colossal $2 billion investment in Mira Murati’s Thinking Machines Lab, a figure that dwarfs typical seed investments and highlights the extraordinary capital being poured into perceived game-changing ventures, especially in the AI sector.

Analyzing the evolution of funding distribution between 2018 and 2025, the trend becomes even more pronounced. Seed rounds in the $200,000 to $5 million range, which once constituted a dominant 70% of all seed funding amounts, plummeted to just 26% by 2025. This precipitous decline demonstrates a significant contraction in the capital available for traditionally sized early-stage ventures. Simultaneously, seed rounds of $5 million and above have steadily gained ground since 2021, maintaining elevated levels in stark contrast to the funding patterns observed in 2020 and earlier. The most significant surge in amounts in 2025 was witnessed in the outlier seed rounds—those deals valued at $50 million and above—which experienced an astronomical increase of over 300%. Even the "larger" seed rounds, ranging from $10 million to $50 million, saw a healthy gain of 20%. These figures paint a clear picture of a seed market increasingly skewed towards substantial capital injections, particularly at the very high end, indicating a "winner-take-all" or "winner-take-most" mentality among investors.

In conclusion, Crunchbase data unequivocally demonstrates that seed funding has by no means stalled; rather, it has undergone a profound transformation. The emergence of artificial intelligence as a dominant technological frontier is fundamentally reshaping seed investment. Multistage venture capital firms and even mid-tier funds are increasingly backing promising companies earlier in their lifecycle and at significantly higher valuations. This phenomenon is often driven by factors such as the esteemed pedigree of the founding team or the impressive early traction demonstrated by the company, especially within the high-growth AI sector. The consequence of this shift is evident in the remarkable increase in larger seed rounds in 2025, with more than 20 outlier deals exceeding $50 million and over 300 deals falling within the $10 million to $50 million range.

This dynamic environment is compelling seed fund managers to adapt their strategies, mirroring the shifts seen at Moxxie Ventures. The market demands flexibility and an understanding of the evolving landscape. Katie Stanton’s astute observation, "It has never been so easy to build a product, and it’s never been so hard to build a business," encapsulates the paradox of the modern startup ecosystem. While technological tools and resources have democratized product development, the challenges of achieving sustainable growth, scaling efficiently, and securing follow-on funding in a highly competitive market remain formidable. Despite the trend towards larger rounds, Stanton also emphasizes the enduring necessity for smaller companies to emerge and for specialized smaller VCs to cater to these diverse constituencies. This highlights the ongoing need for nuanced investment approaches that can identify and nurture innovation across the entire spectrum of early-stage ventures, ensuring that the next breakthrough company, regardless of its initial funding size, still has a pathway to success. The seed market, while more competitive and top-heavy than ever, continues to be a vital crucible for innovation, albeit one that now demands a more strategic and discerning approach from all participants.
