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.

Are you trying to run a hybrid sales motion, but Stripe is limiting your ability to bill your custom contracts? Most of us start on Stripe because it’s the default for self-serve. But as soon as you move into Founder-Led Sales, you hit a wall. When an enterprise customer asks for a ramp-up period, tiered usage, or a custom quarterly billing schedule, Stripe’s standard checkout breaks. You end up with "Billing Debt" - a mess of manual invoices, spreadsheets to track renewals, and "hacked" subscriptions that will eventually require a painful migration. We built Veles to be the sales-led billing layer for Stripe. It’s the flexible "Deal Desk" that lets you sell exactly how your customer wants to buy, without the manual overhead. The Problems We Solve (So You Don't Have To): ✅ Complex Pricing & Logic: Whether it’s usage-based, flat-fee hybrids, or "draw-down" credits, if you can dream up the pricing logic, Veles can bill it through your Stripe account. ✅ Custom Deal Structures: Close deals with custom ramp-ups or non-standard terms without manually editing Stripe objects. ✅ Deal Desk & Approvals: Set guardrails so your first sales hires can’t go rogue on pricing. Build a repeatable approval workflow for every contract. ✅ Presentation Flexibility: Your quotes should look as professional as your product. Veles generates quotes as Web Portals, Slides, Docs, or PDFs—all while staying perfectly synced to your backend. The YC Offer: I want to make sure no YC founder is held back by their billing infrastructure. Current Batch (W26): Veles is 100% Free for your entire founder-led sales phase. Focus on hitting PMF and closing your first 20-50 deals; we’ll handle the "Deal-to-Cash" automation. YC Alumni: 50% off the Growth Plan for one year. Scale your sales team and automate your revenue operations without the "Enterprise CPQ" price tag. Stop forcing your custom enterprise deals into rigid billing templates. Sell what the customer wants, and let Veles keep your Stripe account clean. I’d love to hear from anyone currently fighting with Stripe’s "manual invoice" button. What’s the weirdest contract structure a customer has asked you for lately?

We are Alguna, building a modern platform that helps B2B companies price deals, send quotes, bill customers, and collect payments - all in one place. Our mission is to create the most efficient revenue engine for B2B SaaS. Today, many companies run these processes with spreadsheets and a patchwork of separate tools. That leads to slow approvals, manual work, mistakes, and missed revenue—especially as pricing gets more complex. Alguna replaces that mess by connecting the entire flow from **quote to cash**: what sales sells becomes what finance bills, automatically. We help teams automate invoicing, handle usage-based or custom pricing, and reduce back-and-forth between sales, finance, and engineering. The result: growth-stage startups and enterprises can close deals faster, bill accurately, and scale revenue operations without adding headcount or building internal systems.

CatchAll by NewsCatcher is a recall-first web search API built for queries where the results are spread across hundreds or thousands of pages on the web. Instead of returning the top ranked links like traditional search engines, CatchAll retrieves a large candidate set from the web, validates which pages actually match the query, and extracts structured records of real-world events. Developers and data teams use CatchAll to answer “long-list” questions such as tracking regulatory actions, funding rounds, product launches, corporate expansions, or cybersecurity incidents. The output is not just links but clean, deduplicated datasets that can power AI agents, monitoring systems, analytics pipelines, and market intelligence workflows. CatchAll runs on the data infrastructure developed by NewsCatcher, which continuously indexes millions of articles and public web pages across a global network of sources.

Tailor is the headless ERP that gives fast-growing retail brands a composable, API-first platform to run operations with speed, flexibility, and control. 🧱 Legacy ERP is too rigid: Systems like NetSuite and SAP take months (or years) to implement and break with every change. Tailor is modular, headless, and easy to adapt. 🧩 Point solutions don’t scale: Tools like inventory or order management software solve one problem, but can’t talk to each other or keep up with growth. 📊 Spreadsheets are everywhere: From demand planning to purchase orders, even $100M+ brands still rely on Excel. Tailor replaces duct-taped workflows with ops modules you can tweak, combine, or scale ⚡️ Complex workflows need custom logic: Whether it's multi-location inventory, DTC + B2B orders, or light manufacturing (like kitting or lot tracking), Tailor supports flexible automations out of the box. 👟 Operators can move faster: Launch backend modules in minutes, not months. Tailor's low-code tools let teams build, automate, and adapt without waiting on engineering or implementation agencies. Built for composable retail: - Headless backend with GraphQL APIs - 50+ integrations (Shopify, QuickBooks, 3PLs, etc.) - Custom automations via Pipelines, Functions, and Event Triggers - State machines for approvals and multi-step workflows - AI features like OCR and vector search built in Tailor is already powering operations at fast-growing omnichannel brands and modern manufacturers.
