CTGT logo

CTGT

CTGT safeguards against reputational risk from GenAI across your org

Enterprises are paralyzed by the risks of deploying generative AI. Traditional methods like RAG and fine-tuning are brittle, expensive, and fail to prevent costly hallucinations or guarantee compliance in high-stakes environments. This lack of trust stalls innovation and blocks ROI. CTGT ensures strict, auditable adherence to your policies on the fly. We deliver defensible audit trails and remediate noncompliant model behavior, so outputs become more aligned with company policies over time, combating data and model drift. CTGT is backed by Google's AI fund (Gradient), General Catalyst, and luminaries like Paul Graham. We provide the control and confidence necessary to unlock the full potential of enterprise AI.

CUTR logo

CUTR

The marketplace for wood manufacturing

Look around you - everything you see that was made with wood a designer conceived and then a woodworker has made. Most of the time, something went painfully wrong. 60% of the $1.4T global woodworking market is serviced by small businesses with inefficient, manual processes - Cutr is digitising their workflow. This market is massive, chaotic and surprisingly manual. Woodworkers are mostly offline, hard to find and even harder to vet. They need help with critical back-of-house jobs like quoting and capacity planning. Customers have no idea where to find them and need help asking the right questions & providing the right info to get their job produced correctly. Cutr solves discovery, pricing, payments and workflow for the woodworking market. Our users simply upload a file, accept an instant quote, and get their parts delivered. To make that possible we do the heavy lifting: filechecks, automated quoting, matchmaking, creating job packages, tracking changes & updates, logistics and payments. Cutr saves time, cuts costs and ensures quality with a smooth workflow.
