Alberto here with your weekend startup news.

Grab your coffee.

Let's talk about the five biggest funding rounds that closed this week — because what VCs bet on tells you where the market is actually moving.

What they do: Workflow orchestration for AI
Led by: Andreessen Horowitz
Why it matters:

Temporal guarantees that software workflows finish — even when systems crash. Think of it as insurance for AI agents and long-running processes.

The company's "durable execution" tech has become critical as enterprises deploy autonomous AI that can't afford to fail halfway through a task. Customers include Snap, Netflix, and Coinbase.

The signal: As AI moves from demos to production, reliability infrastructure becomes more valuable than the AI models themselves.

What they do: Building the ISS's replacement
Led by: Qatar Investment Authority, Type One Ventures
Why it matters:

The International Space Station retires later this decade. Axiom is building its replacement — a modular commercial station for research and tourism.

First modules launch to the ISS in 2026. The round includes both equity and debt, positioning Axiom as the frontrunner in the post-ISS orbital economy.

The signal: Space infrastructure is transitioning from government-funded to commercial. The economics finally work.

What they do: AI video generation
Backed by: General Atlantic, Nvidia, Adobe, AMD, Fidelity
Why it matters:

Runway makes AI that generates video from text prompts. The company is moving beyond short clips into "world models" — AI that understands physics, lighting, and motion.

Participation from Nvidia, Adobe, and AMD signals that AI video is infrastructure, not a feature. Total raised: ~$860M.

The signal: AI video is moving from novelty to production tool. Hollywood, ad agencies, and game studios are building workflows around it.

What they do: Workflow orchestration platform
Led by: Andreessen Horowitz
Why it matters:

Based in Bellevue, WA, Temporal provides "durable execution" that guarantees software workflows complete despite failures. As companies deploy autonomous AI agents and long-running processes, reliability tech becomes essential.

The $5B valuation (up from $1.5B in prior round) shows investors are willing to pay premium multiples for infrastructure that prevents AI from breaking in production.

The signal: The next bottleneck isn't compute or models — it's making sure AI actually works when you deploy it.

What they do: AI agents that design semiconductors
Backed by: Undisclosed (strategic + financial)
Why it matters:

ChipAgents uses AI to automate chip design workflows — helping engineers iterate faster and catch design flaws earlier.

With chip development cycles taking 2-3 years and costing hundreds of millions, any tool that compresses timelines or reduces errors has massive ROI.

The signal: AI is eating its own infrastructure. The chips that run AI are now being designed by AI.

Three patterns jump out:

1. AI Infrastructure > AI Applications

Every deal this week is selling picks and shovels to AI companies. Temporal makes AI reliable. Runway makes AI video production-ready. ChipAgents makes chips faster.

Nobody's funding consumer AI chatbots. Everyone's funding the infrastructure that makes AI deployable at scale.

2. "Physics-Aware AI" Is The New Wave

Runway's shift to "world models" and ChipAgents' focus on semiconductor physics both point to the same trend: AI is moving from pattern recognition to understanding physical constraints.

This unlocks massive markets — video production, chip design, robotics, autonomous vehicles — that require AI to understand how the real world works.

3. Mega-Rounds Are Back (For The Right Companies)

$300M+ rounds used to be rare. This week we saw three.

But notice: These aren't early-stage moonshots. They're late-stage companies with revenue, customers, and proven product-market fit. The bar for mega-rounds is higher than 2021, but capital is flowing again.
