This week’s momentum reflects a renewed investor focus on defensible, data-driven models and advanced technologies poised for commercialization.

Top Industries of the Week:

Biotechnology ($890.06M)

Biotechnology companies led the charge this week, raising a significant $890.06 million across six deals. This impressive total was heavily influenced by Neuralink’s colossal $650 million Series E round in California, underscoring the strong interest in neurotechnology. Other notable biotech fundings included GRIN Therapeutics’ $140 million Series D in New York and Vima Therapeutics’ $60 million Series A in Massachusetts, showcasing diverse areas of innovation within the sector. Vivodyne also contributed with a $40 million Series A in California.

Analytics ($420M)

The Analytics sector secured the second-highest funding this week, with $420 million distributed across two companies. ClickHouse’s substantial $350 million Series C round in California and Hex Technologies’ $70 million Series C, also in California, demonstrate a robust appetite for data insights and analytical solutions.

Artificial Intelligence (AI) ($328.97M)

Artificial Intelligence (AI) continued its strong funding momentum, attracting $328.97 million across 24 deals, the highest deal count of any industry. Snorkel AI’s $100 million Series D and Prepared’s $80 million Series C, both based in California and New York respectively, highlight significant growth-stage investments. Early-stage AI companies also saw considerable activity, with Chalk ($50 million Series A, California), Pallet ($27 million Series B, California), and Creatify AI ($15.5 million Series A, California) securing notable rounds. The broad distribution of AI deals across various funding stages signals a vibrant and expanding ecosystem.

Software ($109.83M)

The Software industry garnered $109.83 million in funding across ten deals. Empathy’s $72 million Series C in New York and Superblocks’ $23 million Series A, also in New York, were the largest rounds in this sector. This consistent funding reflects the ongoing demand for innovative software solutions across various applications.

Funding Stage Analysis:

Funding stages ranged from small seed rounds to huge late-stage deals:

Series E ($650M)

Series E funding was the single largest contributor to this week’s total, with one deal alone accounting for $650 million. This high-value round indicates that substantial capital is being deployed into highly developed companies that are likely market leaders or are on the cusp of major milestones, such as an IPO or significant expansion. It signifies a belief in their established business models and future growth potential.

Series C ($645.60M)

Series C rounds collectively secured a remarkable $645.60 million across seven deals. This stage is crucial for companies that have achieved product-market fit and are ready to scale their operations significantly. The healthy amount raised in this stage suggests a robust pipeline of growth-stage companies attracting substantial follow-on investments to expand their market reach, develop new products, or explore new geographies.

Series A ($361M)

Series A financings demonstrated consistent activity, bringing in $361 million across 12 deals. This stage is vital for startups transitioning from initial product development to building out their teams and establishing a solid market presence. The consistent investment at Series A indicates that a good number of promising ventures are successfully navigating the early stages of growth and are being positioned for further scaling.

Seed ($133.40M)

Seed rounds were the most numerous this week, with 53 deals, but they collectively raised a more modest $133.40 million. This high deal count, despite smaller individual check sizes, is a strong indicator of a thriving entrepreneurial environment. It reflects a widespread willingness to make early bets on new ideas and innovative teams, feeding the broader startup ecosystem with a constant influx of nascent companies.

The past week saw US startups secure $2.19 billion in funding, with a clear pattern across stages. While early-stage investments (Seed and Pre-Seed) were abundant, comprising 66 deals and $160.39 million, the bulk of the capital flowed into later-stage rounds. Series E, with one deal, dominated at $650 million, and Series C, with seven deals, brought in $645.60 million. Combined, these two stages accounted for nearly 59% of all funding despite representing only 8 deals. This indicates a dual investment strategy: fostering a broad base of new ventures while heavily capitalizing on proven, growth-stage companies.
