What CTGT does

CTGT is an applied AI research laboratory fundamentally solving the alignment and reliability bottleneck for enterprise AI. For enterprises, especially highly regulated industries, deploying Generative AI is historically a compromise between capability and catastrophic risk. Standard enterprise approaches, such as RAG, fine-tuning, and prompt engineering, operate at the wrong abstraction layer. They are inherently probabilistic, carry massive engineering overhead, and fail to deliver the mathematical certainty required by the Fortune 500. We focus on the science of representation engineering and have productized mechanistic interpretability. By opening the "black box" of neural networks, CTGT has developed a proprietary architecture that intervenes directly at the model's representation layer. We convert complex corporate SOPs, SEC/FINRA regulations, and strict editorial rulebooks into machine-readable "Policy as Code," enforcing deterministic constraints and defensible audit trails without requiring expensive model retraining. The result is a step-function breakthrough in enterprise AI economics and capability. Our fundamental architecture allows organizations to run secure, self-hosted open-source models that mathematically match the reasoning and performance of frontier models. Benchmarks from our enterprise deployments demonstrate a 96.5% prevention of hallucinations, up to a 3.3× accuracy multiplier in complex domain-specific tasks, and an 80-90% reduction in human-in-the-loop manual review. Backed by an $8M seed round from Gradient Ventures (Google), General Catalyst, and Y Combinator, CTGT is currently deployed with Fortune 500 companies, including Tier-1 financial institutions and global media conglomerates, giving them the deterministic control necessary to deploy enterprise AI with zero margin for error.

The deterministic layer for frontier intelligence

What is your company going to make? Please describe your product and what it does or will do.

We build a proprietary AI architecture that turns enterprise policies, regulations, and SOPs into machine-readable code enforcing deterministic constraints at the model's representation layer. This makes deploying generative AI reliable and auditable for highly regulated industries without retraining models.

Where do you live now, and where would the company be based after YC?

We live and work in San Francisco, and the company will remain based here after YC.

Explain your decision regarding location.

San Francisco lets us recruit top AI and engineering talent and stay close to early Fortune 500 customers in finance and media. It's the natural hub for enterprise AI infrastructure companies like ours.

Frequently Asked Questions

Is this the real CTGT YC application?

No. Y Combinator keeps submitted applications private. This is a reconstruction: the real YC form questions, answered from CTGT's public data (launch notes, founder backgrounds, product description). It shows how a company like CTGT would present itself to YC, not the text they submitted.
