Instinct’s $250M leads the stack

Six core company packages near $825M cleared before the 08:45 AM PT cutoff on Aug. 27, after labeling REGENT’s debt half and Socure’s primary-plus-tender mix.

Instinct raised a $250M Series B at a $2.5B valuation, co-led by Index Ventures and Benchmark. The new check brings total funding for Spear Street Technology’s personal AI assistant to $350M. The product remains in private beta. 1

REGENT Craft closed a $240M Series B package split evenly between equity and debt. Mare Liberum and AE Ventures co-led; Erebor Bank supplied the debt half. DCVC, Founders Fund, Lockheed Martin Ventures, and Japan Airlines joined. Total capital raised sits near $340M across equity and debt as the company scales Seaglider manufacturing in Rhode Island. 23

Quaise Energy finished an $180M Series B equity close, including $35M from Nabors Industries and a drilling framework agreement. Prelude Ventures led the July first close with JERA and Idemitsu Kosan. Total funding reaches $280M for Project Obsidian. 4

Socure announced a $156M strategic growth package at a $5.2B valuation led by Summit Partners, mixing primary capital with an employee tender. Goldman Sachs Alternatives, Wells Fargo, and Docusign participated. Socure is also buying agentic fraud platform Fravity. Q2 ARR stood at $364M. 56

Two more confirmed rounds filled the stack: Cyclic Materials raised a $75M strategic growth financing led by accounts advised by T. Rowe Price, taking total equity to $237M; Deep Cogito closed a $43M Series A led by TQ Ventures, with Benchmark, Nexus, Atreides, South Park Commons, and Zscaler participating, and total funding above $56M. 78

Also in the window, outside the $825M core: Helcim closed a C$53M Series C at a C$250M valuation led by BDC’s Growth Venture Fund, and CivilGrid raised a $26M Series A led by Spark Capital. 910

Within this sample, the largest new equity check bought a consumer AI agent still in private beta, while the next tier funded seaglider manufacturing, superhot geothermal drilling, identity-and-fraud infrastructure, rare-earth recovery, and model post-training. Stage labels and financing structure still matter more than a headline total when the reader moves from triage to diligence.
