Apr 2025 Pulse

Apr 2025 in brief.

The count rose to 15 while the floor stayed at ≥$1.14B — no event above True Anomaly’s $260M Series C (Accel), which itself included debt. Space & Launch was the busiest domain with four: True Anomaly’s Jackal spacecraft for space security, Apex Space’s $200M Series C for productized satellite buses (Point72, 8VC, with explicit Golden Dome framing), MDA Space’s $193M all-cash purchase of SatixFy for satcom chipsets, and Aetherflux’s $50M Series A for space-based solar power. SandboxAQ added roughly $150M to its Series E. Kodiak Robotics announced its SPAC combination with more than $110M of committed financing, partly on Army ground-autonomy work, and Karman bought Metal Technology Inc. for $90M for refractory alloys used in strategic missile programs. Three of the five acquisitions were undisclosed: Fisica’s Space Vector add-on, Avem Partners’ purchase of FMI Aerostructures out of Chapter 11, and UVision’s Trim Robotics. Munich’s ARX Robotics ($35.2M Series A) led a small European contingent.

April is the tape at its most granular: many sub-$50M checks into ground autonomy, GPS-denied navigation (Theseus), machine identity (Corsha), logistics AI (Gallatin) and isotope enrichment (Hexium). The Apex and True Anomaly rounds are the first Golden Dome-framed financings in the archive; both companies raise again within twelve months, at $200M and $650M. The FMI Aerostructures purchase is a reminder that distressed aerostructures suppliers are still changing hands at the bottom of the industrial base.

Activity vs each domain’s own baseline.

Each cell is the number of publicly announced deals in that domain and month. Color compares the month with that domain’s own average over the months shown — not a scale shared across domains — so a dark cell in a small domain means “busy for that domain”, not “large in dollars”. Domains with fewer than 12 events in the window are shown in gray without color. Absolute totals across all 24 months are on the archive home.

The archive begins in Sep 2024, so this issue shows 8 of the usual 12 baseline months; averages use the months shown.

No domain moved outside its normal range.

No domain yet has enough history for a percentage callout. We flag a domain only when its last three months differ from the prior three by 30% or more and it has at least 36 events in the trailing 12 months. Smaller samples stay as raw counts on the heat map; we never quote month-over-month percentages.

A full section (narrative and table) for any domain with five or more events this month; a compact list otherwise. Each event has one primary domain: the market the money is buying.

Method & coverage

Public sources only · Issue window = first public announcement in Apr 2025 · 15 announced or closed events (F 9 · M 5 · P 1) · Disclosed floor ≥$1.14B across 12 of 15 (20% undisclosed) · Closings of deals first announced in an earlier month are not counted again here · Capital-supply items are sidebar-only and excluded from domain statistics · Heat-map colors use each domain’s own trailing-12-month baseline.
