Alleria AI, Inc. builds AI products and infrastructure that help businesses turn communication into actionable business intelligence. Our product ecosystem includes PriorityEngine, an inbox intelligence platform for businesses, and BSOS, an OEM Business Communication Intelligence API designed for software platforms, AI agents and business workflows. BSOS transforms email, messages, tickets, forms, documents and other business communication into structured intelligence including business signals, understanding, context, classification, business facts, business impact, attention, priority, recommended action and explainability. We also operate the Alleria Partner Channel, an invitation-only commercial ecosystem for technology consultancies, agencies, integrators, implementation partners and other B2B technology organizations that want to introduce PriorityEngine or integrate BSOS into relevant customer solutions. Partners retain their own customer relationships while gaining access to recurring commission opportunities on eligible attributed customer revenue.

Alleria AI, Inc. is a Delaware corporation serving customers and technology partners internationally.

Firecrawl is the easiest way to turn the web into data AI agents can use. One API call converts any URL into clean, LLM-ready markdown or structured data - the boring-hard problem everyone building with LLMs eventually hits, solved. We hit 8 figures in ARR in year one and more than doubled it in year two. We have 150k+ GitHub stars, and developers, agents, and category-defining AI companies build on us every day. Growth like this is rare, and we're just getting started. We're a small team punching far above our weight. Everyone here owns a real piece of the product and company, end to end, and runs it themselves - no hiding behind process or headcount. This is a place for people who want to work at the frontier: an AI company building the infrastructure other AI companies run on, not one bolting AI onto an existing product. We move fast, go deep, and are building the tools superintelligence will rely on to gather data from the web.

Scrydex is building the developer infrastructure layer for trading card games. We provide APIs, datasets, and computer vision tools that help marketplaces, inventory systems, mobile apps, retailers, and collectors work with trading card data at scale. Developers use Scrydex to search cards, identify cards from images, access pricing and metadata, manage collections, and build TCG-powered products without spending years maintaining card databases themselves. The hard problems we solve involve data normalization, large-scale card cataloging, image recognition, pricing aggregation, and maintaining accurate information across dozens of games, languages, printings, variants, and regions. Trading card data is fragmented, constantly changing, and often inconsistent across sources. We build the infrastructure that turns that complexity into a simple API experience for developers. Today Scrydex powers applications used by collectors, stores, marketplaces, and software teams around the world.

GateOfAI is a bilingual platform and talent network designed to bridge the gap between technical AI builders and real-world commercial demand. The Problem: Traditional freelance platforms are saturated with noise, making it difficult for enterprise clients to identify engineers capable of shipping production-grade agentic workflows, RAG systems, and custom automation. Concurrently, developers lack structured distribution to monetize ready-made AI tools and micro-SaaS. What We Do: 1. Tool Monetization: Empower engineers to publish and sell AI workflows, APIs, and tools directly via subscription models. 2. Verified Enterprise Matching: Connect vetted builders to bespoke business contracts and custom client pipelines. 3. Automated Evaluation: Streamline onboarding through focused, on-demand technical AI screening to eliminate recruiter friction. We operate globally with a remote-first team, supporting both English and Arabic AI development ecosystems.
