Paygent is the monetization and cost-tracking infrastructure platform built for AI-native businesses. Unlike legacy billing tools that only track revenue, Paygent gives AI companies real-time visibility into margins, infrastructure costs, and profitability per customer and per agent workflow. AI companies today operate across fragmented LLM providers, APIs, and cloud infrastructure, making it difficult to understand true unit economics. Teams often scale usage without realizing margins are shrinking. Paygent solves this by unifying real-time AI infrastructure cost attribution and automated billing into one platform. It tracks every LLM call, API request, and compute event tied to agent workflows, enabling customer-level gross profit visibility, automated billing, predictive pricing simulation, and cost alerts to prevent runaway agent loops. Built for AI startups, voice AI platforms, and autonomous agent teams, Paygent offers native SDKs for Node.js, Python, and Go.

Gladia is a speech-to-text platform built for production, turning raw audio into structured outputs that power real workflows like meeting summaries, CRM enrichment, contact center QA, and real-time voice assistants. With support for 99+ languages and the ability to handle messy real-world audio—overlapping speakers, accents, code-switching, domain-specific terminology—Gladia is designed for the complexity of actual conversations, not clean studio recordings.

Mercury Edit 2 is part of Inception Labs’ Mercury family of AI models, designed to perform high-speed reasoning, coding, and editing tasks using a fundamentally different architecture from traditional large language models. It builds on Mercury 2, a diffusion-based reasoning model that generates and refines entire outputs in parallel rather than producing text token by token, enabling significantly faster performance and more responsive editing workflows. Instead of acting like a sequential “typewriter,” the system behaves more like an editor, starting with a rough draft and iteratively improving it across multiple tokens at once, which allows for real-time interaction and rapid iteration in tasks such as code editing, content generation, and agent-based workflows. This architecture delivers throughput of up to around 1,000 tokens per second, making it several times faster than conventional models while maintaining competitive reasoning quality across benchmarks.

Hindsight is an agent memory system built to create smarter AI agents that learn over time instead of starting every conversation from zero. Most agent memory systems focus on recalling conversation history, but Hindsight is focused on making agents learn, not just remember. It gives AI agents persistent long-term memory using biomimetic data structures, helping them retain facts, recall relevant context, and reflect on experience as part of reasoning. Hindsight is designed for agents that need to understand who a user is, what has been discussed, what preferences have emerged, what decisions were made, and how behavior should adapt across sessions. It provides three core operations: retain, recall, and reflect. Retain stores new information, recall retrieves the right memories when needed, and reflect helps agents synthesize observations, form mental models, and learn from prior interactions.

AI Workers are autonomous agents built for your business; specialized AI workers that act like real coworkers, not chatbots you prompt. They come with their own professional profile, email, phone number, Slack and Teams presence, initiative, and the ability to work 24/7 without waiting to be asked. Instead of telling them exactly how to complete every step, you set the goal, and they build the workflow, whether that means daily reports, weekly follow-ups, CRM updates, client communication, research, content, finance tasks, HR coordination, design work, development support, or other recurring business operations. It includes specialized AI Workers across marketing, development, design, HR, finance, and other business functions, with each worker designed around a clear role and practical use cases. AI Workers can connect to more than 3,000 tools, including Slack, Microsoft Teams, Gmail, Notion, HubSpot, Salesforce, and other business apps.

Inworld TTS is a state-of-the-art text-to-speech platform designed to deliver ultra-realistic, context-aware speech synthesis and precise voice-cloning capabilities at a radically accessible price. The flagship model, TTS-1, is optimized for real-time applications and supports low-latency streaming (first audio chunk in ≈200 ms) as well as multiple languages (including English, Spanish, French, Korean, Chinese, and more). Developers can use instant zero-shot voice cloning (5-15 seconds of audio) or professional fine-tuned cloning, add voice-tags for emotion, style, and non-verbal sounds, and switch languages while preserving voice identity. The larger TTS-1-Max model (in preview) offers even more expressive speech and multilingual strength. The platform supports both API and portal access, streaming or batch mode, and is designed for everything from interactive voice agents and gaming characters to branded audio experiences.

Operata is an AI-powered CX observability platform built exclusively for cloud contact centers that continuously collects and correlates real-time data from every call, agent environment, network, CCaaS and AI interaction to provide end-to-end visibility into customer and agent experience so teams can understand not just what happened but why it happened and act on it quickly; its features include a unified CX Insights Graph that harmonizes technical, operational and experience signals, CX Copilot and Agent Copilot assistants powered by Tenor AI for natural language querying and on-the-fly recommendations, Customer Journey Trace to visualize complete interaction sequences across multiple platforms, pre-built playbooks and interactive dashboards for proactive insights, readiness testing and assurance tools to benchmark performance, seamless integrations with 50+ CX and voice systems, and an MCP Server to feed observability data into enterprise AI stacks.

Prompt optimization, automated voice testing, monitoring, and more. Test your AI voice agent against 1000s of simulated users in minutes. AI voice agents are hard to get right. A small change in prompts, function call definitions or model providers can cause large changes in LLM outputs. We're the only end-to-end platform that supports you from development to production. You can store, manage, version, and keep your prompts synced with voice infra providers from Hamming. This is 1000x more efficient than testing your voice agents by hand. Use our prompt playground to test LLM outputs on a dataset of inputs. Our LLM judges the quality of generated outputs. Save 80% of manual prompt engineering effort. Go beyond passive monitoring. We actively track and score how users are using your AI app in production and flag cases that need your attention using LLM judges. Easily convert calls and traces into test cases and add them to your golden dataset.
