2024, Year in Review
The year AI infrastructure went from category to platform, agentic AI hit early production, and incumbents executed historically large M&A.
2024 was the year AI infrastructure stopped being a category and started being a platform layer. The companies shipping picks-and-shovels (Modal, Groq, Together, Fireworks, Replicate) consolidated revenue and engineering talent at unprecedented rates. The frontier-lab cohort hit clear commercial differentiation, Anthropic's safety-first product moat, OpenAI's GPT-4o multimodal expansion, Mistral's open-weight European bet. Meanwhile incumbents made historically large M&A bets: Cisco's $28B Splunk acquisition closed, IBM announced its $6.4B HashiCorp deal, and Google announced (and walked back, then re-announced) Wiz at $32B.

AI infrastructure: from category to platform
AI infrastructure companies moved from competing with each other to consolidating their layer of the stack. Modal, Groq, Together AI, Fireworks AI, and Replicate each shipped major product updates targeting different inference niches, specialist hardware (Groq's LPU), serverless GPU (Modal), aggregated runtime (Together), per-token APIs (Fireworks), and open-weight serving (Replicate). The engineering signal pattern was distinctive: heavy contributor influx tied to GPU-region rollouts and inference-API expansion, often arriving 6-12 weeks before public announcements.
Agentic AI hits early production
Framework adoption matured in 2024, LangChain, LangGraph, and emerging entrants (CrewAI, Letta, Mastra) shipped production-ready primitives. The MCP (Model Context Protocol) shipped from Anthropic and was adopted by Cursor, Claude Desktop, and the broader agent-tooling ecosystem. Agent frameworks shifted from research toy to production infrastructure as Claude Code launched, Cursor crossed $200M ARR, and Lovable demonstrated end-to-end agentic web development.
Historically large M&A
Cisco closed Splunk ($28B) in March, the largest cybersecurity acquisition ever. IBM announced HashiCorp ($6.4B), closing pending regulatory review. Google announced Wiz ($32B), by far the largest acquisition in Google's history. Databricks closed MosaicML ($1.3B) earlier and announced Tabular ($1B) in mid-2024, consolidating the open-source lakehouse layer.
Open-weight models become commercial
Mistral shipped Mistral Large and Mixtral checkpoints under increasingly-commercial licenses. Hugging Face's commercial ecosystem (Inference Endpoints, Enterprise Hub) accelerated. Cohere's enterprise RAG approach matured. The open-weight versus closed-API frontier no longer looked like a binary choice, by end of 2024, every major cloud provider hosted multiple open-weight model families as first-party inference endpoints.
Engineering-signal pattern shifts
The clearest signal pattern of 2024: heavy Rust adoption across the database, edge-runtime, and inference-server categories. Repos that shifted from Go or C++ to Rust during 2024 (especially in the data and infrastructure layers) showed a distinctive contributor-influx pattern as the broader Rust community migrated toward those projects. Repos that DIDN'T shift to Rust often showed flat or declining contributor counts.

Emergent trends to follow
What's likely to define 2025
2025 will be defined by agent infrastructure consolidating to a smaller set of frameworks, durable workflow primitives (Temporal-class semantics) becoming a baseline expectation, and the first wave of AI-acquisition unwinds (companies bought during the 2023-2024 hype-cycle that didn't integrate cleanly). Watch for IBM's HashiCorp close to complete, and for Google's Wiz integration to begin reshaping the cloud security competitive landscape.
