AI Startups to Watch (Sep 4): Gimlet, Baseten & Rilo
AI startups raised $1.8B in 24 hours: Gimlet Labs hits $3B for chip-agnostic inference, Baseten reaches $13B, and Adobe acquires Rilo.
Five AI startups made moves in the last 24 hours that signal where the infrastructure layer, workflow automation, and physical AI are heading. From a $3B inference startup splitting workloads across chip architectures to Adobe quietly absorbing an Indian agentic-workflow founder, here is what matters today.
Gimlet Labs: $300M at $3B to Unify Chip-Agnostic AI Inference
Gimlet Labs raised a $300 million Series B at a $3 billion valuation, led by Andreessen Horowitz with participation from Arm Holdings and Microsoft's M12 venture arm. The round comes just six months after an $80 million Series A at roughly $400 million, marking one of the fastest valuation jumps in recent AI infrastructure history.
Gimlet builds software that splits AI inference workloads across different chip architectures, including GPUs and custom SRAM silicon. The approach directly attacks GPU scarcity and vendor lock-in by letting companies run models on whatever silicon is available, not just Nvidia hardware. The company is actively collaborating with Arm on compatibility for edge and data center deployments.
Why it matters: AI inference costs are the single biggest bottleneck for scaling production AI systems. A platform that works across architectures could reshape how enterprises budget for compute. If Gimlet delivers on its promise, it threatens Nvidia's dominant position in AI deployment by making chip choice irrelevant.

Adobe Acquires Rilo: Agentic Workflows Go Enterprise
Adobe acquired Rilo, an Indian startup that builds plain-English multi-step marketing workflows powered by AI agents. Rilo was founded in September 2025 by IIT Bombay graduates Dhruv Jaglan and Georgi Boby, and had reached 10,000 users before the acquisition. The company previously raised $1 million from Peak XV Partners, DeVC, and Day Zero.
Adobe absorbed Rilo's six-person engineering team. The acquisition signals Adobe's push into agentic AI for its Creative Cloud and Marketing Cloud products, where multi-step automation has been a gap compared to competitors like Salesforce Agentforce and Google's Vertex AI agents.
Why it matters: This is a classic acqui-hire that gives Adobe immediate agent-workflow capability without building from scratch. For Indian AI startups, it validates that small teams building practical automation tools can attract enterprise acquirers within months of founding. The agentic-workflow space is heating up fast.

Baseten: $1.5B Series F as Inference Scale Hits 1B Calls Daily
Baseten raised a $1.5 billion Series F at a $13 billion valuation (with an $11 billion tranche also reported). The company now processes over 1 billion inference calls per day across 87 clusters spanning 18 cloud providers, making it one of the largest independent inference platforms in the world.
Baseten's growth has been driven by multi-model strategies, where customers deploy different AI models for different tasks to optimize cost and performance. The company is tripling headcount to meet demand, growing 20x year over year.
Why it matters: As AI moves from experimentation to production, the companies that control inference infrastructure become the new cloud providers. Baseten's multi-cloud, multi-model approach gives customers flexibility that single-vendor solutions cannot match. At $13 billion, it is now valued higher than many public SaaS companies.

Peregrine Technologies: $250M for Permission-Aware Data Integration
Peregrine Technologies raised a $250 million Series D at a $6.8 billion valuation. Founded in 2018 by Nick Noone and Ben Rudolph, Peregrine integrates siloed data into permission-aware unified environments for government and enterprise clients. The platform lets organizations consolidate data across disconnected systems while maintaining strict access controls.
The company operates in a market that large defense and enterprise contractors have struggled to crack: connecting legacy data systems without creating security vulnerabilities. Peregrine's permission-aware architecture is designed for environments where data sensitivity varies by user and context.
Why it matters: Government AI adoption is accelerating, but data integration remains the critical blocker. Peregrine's approach solves the plumbing problem that keeps agencies from deploying AI at scale. The $6.8 billion valuation reflects confidence that federal and enterprise spending on AI-ready data infrastructure will grow significantly.

Lyte: Physical AI Gets $165M at $1.6B
Lyte, founded by former Apple engineers, raised $165 million at a $1.6 billion valuation to build physical AI for robotics. The company focuses on bridging the gap between simulation and real-world robotic deployment, targeting manufacturing and logistics applications. Source: Crunchbase
Startup Snapshot
| Startup | What They Do | Latest Round | Valuation | Key Differentiator |
|---|---|---|---|---|
| Gimlet Labs | Chip-agnostic AI inference | $300M Series B | $3B | Splits workloads across GPU + SRAM silicon |
| Baseten | Multi-model inference platform | $1.5B Series F | $13B | 1B+ daily calls, 18 cloud providers |
| Rilo (Adobe) | Plain-English marketing workflows | Acquired | N/A | Agentic multi-step automation |
| Peregrine Technologies | Permission-aware data integration | $250M Series D | $6.8B | Government/enterprise data unification |
| Lyte | Physical AI robotics | $165M | $1.6B | Apple alumni building real-world robotics |
Key Takeaways
The infrastructure layer commands the biggest checks. Gimlet and Baseten together raised $1.8 billion in 24 hours, both targeting inference from different angles. Adobe's Rilo acquisition shows enterprise giants are buying AI workflow capability rather than building it. Peregrine's $6.8 billion valuation proves data integration for regulated environments is a massive opportunity.
