Brevoir Signal 002

Brevoir Signal · Weekend Read · Apr 18, 2026

Been thinking about the concentration here, 75.6% across just nine deals, while AI/ML Venture Capital kept pushing up. I am watching whether the money keeps clustering around the same names, or whether the rest of the market finally starts to breathe.

The Call

Slate Skews the Week

Slate at $650.0M is the tell. The Concentration Index hit 75.6%, so capital is clustering hard around a few AI names while the rest of the market fights for scraps. That is a Pattern Break worth watching, because Factory at $150.0M, Slash at $100.0M, and Mintlify at $45.0M all sit inside the same AI-heavy tape. Lean in on AI software and ignore the noise around breadth.

AI/ML Venture Capital scores 92, up 10 points.

Slate’s $650.0M Series C and Factory’s $150.0M Series C kept the tape tilted toward AI software and developer tools. Q1 2026 AI funding hit $242.0B, or 80% of global venture, while Shield AI’s $1.5B Series G signaled defense AI is now institutional capital territory.

Deal

Deal of the Week

Slate, AI software, Series C, $650.0M

Valuation check: Slate priced 400% above the $130M sector median, putting it firmly in the top quartile for Series C AI software.

Slate’s $650.0M Series C is a clear outlier versus the usual AI software check size, which signals sustained conviction in enterprise workflow software. The size alone says this round was written for scale, not experimentation.
