How AI Compressed Time: 3 Years of Market Shifts & Opportunity

Key Insights

• AI compresses development cycles: new models release every 41 days, companies reach $100M revenue in record time
• Venture funding language is obsolete: seed rounds now range from $1M to $500M, reflecting company maturity faster than traditional stages
• Inference is the dominant market: specialized infrastructure (video, batch, local, agentic, real-time) is fragmenting like databases did a decade ago
• Open-source and local models are becoming enterprise-grade: frontier capabilities now run on laptops within quarters
• Agents are revolutionizing security, operations, and back-office work: enabling attack from inside rather than requiring full system replacement

How AI Reshaped Venture Capital Language

Three years ago, Theory Ventures launched with the thesis that AI would fundamentally reshape software development, sales, deployment, and operations. Today, the venture capital lexicon itself has transformed.

Traditional funding stages—Seed, Series A, Series B—no longer describe company maturity. Instead, they reflect the financial products companies seek. Seed rounds now range from $1M to $500M, a massive compression driven by AI acceleration, ecosystem support, and the promise of generational-scale businesses built faster than ever before.

Three years ago, a seed-stage company was typically a small team with a product concept and early signs of product-market fit. Today, some seed rounds exceed the size of historical IPOs—compressed time enables companies to mature earlier than software companies did in previous generations.

Inference Emerges as the Dominant Market

When Theory launched, most AI conversations centered on frontier models competing as the "airlines of the era." The conversation has shifted dramatically: inference is now the dominant market.

Market segmentation reflects evolved workloads and buyer preferences. Very few companies can afford state-of-the-art AI for everyone, creating specialized infrastructure categories: video, batch, local, agentic, and real-time workloads each require different optimization. Companies like Sail Research are building systems that operationalize intelligence—serving it cheaply, routing it intelligently, and specializing around specific use cases.

Databases followed this exact path a decade ago, fragmenting into OLTP, OLAP, vector databases, and streaming systems. Inference infrastructure is now specializing the same way, with new category leaders emerging across the stack.

Open-Source and Local Models Go Enterprise

The gap between closed-source frontier models and open-source alternatives has compressed dramatically. We've reached the "iPhone 15 moment" of AI: many models are now good enough for most work.

Running models locally reduces cost, improves latency, increases control, and minimizes data governance concerns. Enterprises are adopting local and open-source models for sensitive workloads, with frontier capabilities reaching consumer hardware within quarters. Tools like Ollama bring this capability to millions of developers, shifting what once required hyperscaler infrastructure to run on a laptop.

AI Transforms Security, Operations, and Back-Office Work

The attack surface is exploding. MCP servers, skills, plugins, and coding agents introduce new entry points faster than security teams can review them. Defenses must respond to compressed response times—from months to minutes.

Simultaneously, agents are rewriting operations and back-office work. ERP and back-office systems have resisted change for decades due to unglamorous work, messy data, and enormous switching costs. Agents invert this economics by reading documents, reconciling records, and executing workflows from inside existing systems—no rip-and-replace required.

The Real Story: Founders Built It

Theory's three-year journey mirrors the ecosystem's transformation. The firm scaled from a handful of people with a thesis to thirteen team members—engineers, researchers, and investors working directly with the AI systems they back.

A small, deeply technical team now analyzes 2x the investment opportunities with the same leverage AI enables for founders: agents map markets, pipelines surface companies months before they raise, and research infrastructure lets a small team cover ground of a firm several times its size.

Conclusion

In three years, AI compressed decades of company-building into quarters and rewrote enterprise software expectations. Venture capital language evolved, inference emerged as the dominant market, and open-source models reached enterprise grade. The founders building these companies are just getting started—the next three years will make these shifts look slow.
