Want to track the biggest startup funding deals in 2024 with our curated list of US company venture deals valued at over $100 million? Check out the Crunchbase Megadeals board.

This is a weekly feature that provides an overview of the top 10 funding rounds announced in the U.S. of the week. You can find the biggest funding rounds from last week here.

This week definitely saw a drop in big rounds, with only three deals crossing the $100 million mark. Healthcare product and medical device makers did well, however. Perhaps announcements are slowing down as summer comes to a close, but this week definitely seemed to lack the big money that so many deals have brought this year.

1. Kiteworks, $456 million, cybersecurity: Investors once again appear to be interested in cybersecurity. A week after Abnormal Security closed a $250 million Series D that valued the startup at $5.1 billion, secure content company Kiteworks raised a $456 million round from Insight Partners (which also participated in Abnormal’s round) and Sixth Street. The San Mateo, California-based company called the new round “growth capital,” but also said it was a “partial liquidity event,” meaning some investors were able to cash out. While the company did not provide a valuation, it did say it was a minority investment, meaning its valuation is north of $1 billion. Kiteworks’ platform allows customers to share sensitive data with other trusted parties through communication channels like email and file sharing. In 2020, the company raised $120 million in a funding round led by Bregal Sagemount. Kiteworks was founded in 1999 and has raised $592 million. The company was formerly known as Accellion and suffered a major data breach in 2021.

2. Halda Therapeutics, USD 126 million, biotechnology: The big biotech round of the week came from New Haven, Connecticut-based Halda Therapeutics, a biotech startup developing therapies for prostate cancer and breast cancer that received a $126 million Series B extension from investors including Deep Track Capital and RA Capital Management. Halda was founded in 2018 and has raised $202 million to date, according to the company.

3. HistoSonics, $102 million, Healthcare: We usually talk a lot about biotech in this column, but this week was a good week for healthcare and medical technology companies like HistoSonics. The Minneapolis company raised $102 million in a Series D led by Alpha Wave Ventures. The startup’s Edison Histotripsy System uses ultrasound to create a “bubble cloud” designed to specifically destroy and liquefy liver tumors. The company, founded in 2009, has raised nearly $329 million, according to Crunchbase.

4. Neptune Medical, $97 million, medical device: As we said, a good week for medical device makers, as Neptune Medical also managed to raise a lot of money. The Burlingame, California-based medical device maker secured $97 million in Series D funding. The company said Olympus and Sonder Capital were significant participants in that round. Neptune Medical focuses on using robots to combat gastrointestinal diseases. According to Crunchbase, this is the first announced funding amount for the company, founded in 2016.
