Rounds
Autonomous shipbuilder Saronic closed a staggering $1.75B Series D, more than doubling its valuation to $9.25B from $4B less than a year ago. Kleiner Perkins led the round, making it the firm's largest defense tech bet. Saronic builds AI-powered unmanned surface vessels for the U.S. Navy, holding a $392M Navy contract. The capital will fund Port Alpha (a next-gen autonomous shipyard) and expand production in Louisiana and Texas to 20+ ships per year by 2027. Founded in 2022 by combat veteran Dino Radoncic. Total raised: $2.6B.
Human performance wearable company Whoop crossed the $10B mark with a $575M Series G at $10.1B valuation. The screenless fitness tracker measures strain, recovery, and sleep through continuous biometric monitoring, serving professional athletes and consumers globally. Founded in 2012 by Harvard undergrad Will Ahmed, Whoop has raised nearly $1B total across eight rounds. The $10B+ valuation makes it one of the most valuable consumer health companies in the world, surpassing Oura and approaching Peloton's peak market cap.
London-based AI platform for debt markets 9fin hit unicorn status with a $170M Series C at $1.3B. The platform provides leveraged finance, private credit, and distressed debt intelligence to institutional investors, law firms, and banks. HarbourVest led with Canada Pension Plan Investment Board (CPP Investments) participating, a rare combination of institutional allocators investing directly into a fintech startup. Founded in 2016 by former leveraged finance professional Steven Hunter. Total raised: $232M.

News & Signals
Q1 2026 shatters all records: $297B invested in startups globally
Crunchbase reported that investors poured $297 billion into approximately 6,000 startups in Q1 2026, up roughly 150% both quarter-over-quarter and year-over-year, marking an all-time high for global venture investment. AI accounted for $239 billion, or 81% of the total. Late-stage funding reached $244 billion (up 203% YoY) across just 582 deals, while early-stage hit $40.6 billion across 1,800 deals. Seed funding totaled $12 billion (up 30% YoY) but deal counts fell 31%. Four of the five largest venture rounds ever were closed in Q1: OpenAI ($120B), Anthropic ($30B), xAI ($20B), and Waymo ($16B) collectively raised $186 billion, or 64% of all global venture investment. The concentration is staggering: four companies captured nearly two-thirds of all startup capital deployed on Earth in three months.
Markets rally on Iran ceasefire hopes: S&P 500 gains 1%, oil drops below $100
Stocks had their best day in weeks after President Trump posted on Truth Social that Iran's president had asked the U.S. for a ceasefire. The S&P 500 rose 1%, the Nasdaq gained 1.6%, and the Dow added 418 points. WTI crude fell to $99.96, dipping below $100 for the first time in days. Brent dropped 2% to $101.89. Iran's foreign ministry called the ceasefire claim 'false and baseless,' but markets chose to price in the optimistic scenario. Trump added that the U.S. would consider the offer 'when the Strait of Hormuz is open, free, and clear,' leaving the standoff unresolved but creating the first meaningful de-escalation signal since February 28.
Saronic joins the defense tech unicorn club at $9.25B
The defense tech sector now has three companies valued above $5B: Anduril ($30.5B), Shield AI ($12.7B), and Saronic ($9.25B). Combined, they have raised over $7.5B in the past 12 months alone. Saronic's growth is particularly striking: from founding in 2022 to $9.25B in four years, driven by a single Navy contract and the thesis that autonomous surface vessels will transform naval warfare. The investor list (Kleiner Perkins, Advent, Bessemer, a16z) represents every category of institutional capital: venture, growth equity, and defense-focused funds. The through-line from Shield AI (pilotless aircraft) to Saronic (crewless ships) is clear: autonomy across every domain of warfare is no longer speculative, it is fundable at scale.
depthfirst: from stealth to $120M in 90 days, the new speed of AI fundraising
depthfirst emerged from stealth on January 14 with a $40M Series A, then closed an $80M Series B less than 90 days later. This cadence, which would have been extraordinary even in 2021, is becoming normalized for AI-native companies that demonstrate rapid enterprise adoption. The company announced its first in-house security model (dfs-mini1) alongside the Series B, signaling that it is building proprietary models rather than wrapping existing LLMs. The Meritech Capital lead at Series B (a firm known for late-stage pre-IPO investments) at such an early company stage suggests they see depthfirst as a potential rapid-scale outcome in AI cybersecurity.
VC Mood on X
The last day of Q1 brought two things VCs desperately needed: a market rally and a ceasefire signal. The S&P gaining 1% after five straight weekly declines felt like oxygen to investors who had spent March watching their public comparables deteriorate. Several GPs noted that the Iran ceasefire rumors, even if denied by Iran's foreign ministry, shifted the narrative from "how bad will it get" to "when does it end." That shift, however tentative, matters for deal-making psychology.
The $297B Q1 number provoked the most debate. The bulls pointed to it as evidence that AI investment is secular, not cyclical: "Four companies raised $186B. The other 5,996 raised $111B. The non-mega-round market is still growing 38% YoY. That is healthy." The bears countered that concentration at this level is a systemic risk: "When four companies account for 64% of all global venture capital, the 'venture capital' label no longer describes what is happening. This is corporate financing for frontier AI labs, not a functioning startup ecosystem."
Saronic's $1.75B close at $9.25B made it the third $1B+ defense tech round in March (after Shield AI's $2B and Anduril's reported new round talks). "March 2026 will be remembered as the month defense tech became big tech," one partner posted. The underlying driver is increasingly clear: the Iran conflict is not just moving markets, it is moving capital allocation. Every dollar of military spending validates the autonomous systems thesis. Saronic building 20 ships per year by 2027 is not a startup metric, it is an industrial production target, and the investors pricing it at $9.25B are making an industrial bet.
