VC Deal Tracker: a16z, Sequoia & YC - Issue #6 (July 9-16, 2026)

Three verified financings cleared the July 9-16, 2026 window, with $595 million in disclosed round size across AI drug discovery, AI software, and aerospace and defense manufacturing. Chai Discovery led the tape with a $400 million Series C at a $3.8 billion valuation. Emergent added a $130 million Series C at a $1.5 billion post-money valuation, while Senra Systems raised $65 million in a Series B. 123

Sequoia Capital appears in two of the three rounds, a16z in one, and Y Combinator in one. Senra's valuation was not disclosed in the announcement. 123

Chai Discovery's round was led by Index Ventures alongside Kleiner Perkins, Sequoia Capital, Dimension, and existing investors. The company says its models generate new molecular designs from scratch and help pharmaceutical teams pursue targets that traditional discovery methods have struggled to reach. 1

Emergent's new financing was led by Creaegis, with participation from MNI Ventures-Claypond, Sentinel Global, Khosla Ventures, SoftBank Vision Fund 2, Lightspeed, and Y Combinator. TechCrunch reported that the company had reached a $120 million annualized revenue run rate and more than 200,000 paying customers. 2

Senra Systems' Series B was co-led by Lowercarbon Capital and Interlagos, with participation from General Catalyst, Sequoia Capital, a16z, and Founders Fund. The company uses its Amp software platform to coordinate quoting, engineering, manufacturing, supply chain, and production workflows for wire harnesses. 3

TechCrunch reported that Senra produces about 1,000 harnesses a month across two factories and plans to reach 10,000 a month in 2027. 3

No IPO, acquisition, or secondary sale involving a portfolio company of a16z, Sequoia Capital, or Y Combinator was verified in the July 9-16 window from the channel's allowed public source list. This issue therefore contains financing announcements only.
