Paid is the first unified monetization engine specifically engineered to solve the complex unit economics of the AI era. In the rapidly evolving landscape of artificial intelligence, the traditional SaaS metrics that once defined success are becoming obsolete. As companies shift away from human-centric "seat-based" licensing toward autonomous agentic workflows, the financial infrastructure supporting these businesses must also evolve. While legacy billing systems are built for static user counts, Paid provides a robust, four-pillar infrastructure designed to turn AI capabilities into sustainable, high-margin revenue streams: 1. Actionable Signals At the core of AI monetization is the ability to interpret massive amounts of raw execution data. Paid provides Task-Level Visibility, transforming opaque system logs into clear, actionable signals. This allows organizations to see exactly what work their agents are performing in real-time, providing the granular data necessary for informed decision-making. 2. Proof of Value The "per-seat" model often relies on guesswork regarding how much a tool is actually being used. Paid replaces this ambiguity with Real-Time ROI. By assigning tangible value to specific agent actions, the platform enables your customers to witness the literal return on their investment as it happens. This transparency builds trust and justifies the transition to consumption-based pricing. 3. Real-Time Margin Intelligence AI infrastructure costs - like token usage and compute - can fluctuate wildly. Paid connects directly to AI APIs to track margins by product, customer, or individual feature. This level of intelligence allows you to stop guessing at delivery costs and start proactively protecting your bottom line from unexpected overhead. 4. Unified Monetization Paid goes beyond simple billing; it is a comprehensive ecosystem. From complex credit management and metering to expert strategic consulting, it is the only platform providing end-to-end solutions. By unifying the entire monetization lifecycle, Paid ensures your AI strategy is not just innovative, but inherently profitable and scalable.
PortaAIM is an inference service delivery platform that combines PortaBilling with an AI gateway to authorize, meter, and settle AI usage in real time. It checks the customer, pricing rules, and balance before a request runs, reserves funds against the worst-case cost, then meters actual usage in tokens, images, audio, tool calls, or other units and releases any unused balance. Pricing, tokens, credits, and bundles are configured without code changes, and resellers are settled within the same system. PortaAIM routes requests to the lowest-cost capable model, offers a white-label customer portal, and runs across multiple sites for continuity. It supports full API and MCP access, and includes guardrail modules for frameworks such as the EU AI Act. Available as perpetual license or pay-as-you-go, self-hosted or hosted by PortaOne — built on 25+ years of real-time billing experience for nearly 500 operators worldwide.
RevGate is the Unit Economics platform for AI agents. It helps AI-native companies price execution and outcomes, not just usage - protecting margins and reducing revenue leakage. With usage-based, outcome-based, and hybrid billing, RevGate tracks agent activity, attributes value, and aligns pricing with performance. Built for autonomous systems, it delivers clear unit economics, cost control, and scalable revenue infrastructure for the agent economy.
RocketFuel Recharge is billing and payments infrastructure for third-party logistics providers. Instead of fronting carrier costs and chasing client invoices thirty days later, a 3PL holds prepaid balances from its brand clients and meters each shipment against that balance in real time. You get paid before the package ships. Money never sits with RocketFuel. When a client funds a balance, the money ACHs directly into the 3PL's bank account. We meter it in software; you keep custody and the float. Recharge Meter — the flagship. Prepaid client balances drawn down as each label prints, with automatic top-ups when a balance falls below threshold. Advanced Rate Markups — a rule engine for what you charge. Cost-plus, margin-based, flat fee, percentage or tiered, configured per customer, carrier, service, warehouse, zone or weight tier. Adjustment Reconciliation — carrier corrections caught at invoice time. DIM bumps, zone changes, weight corrections, fuel surcharges and late-delivery refunds are matched back to the original shipment, re-priced against your markup rules, and applied to the meter across UPS, FedEx, USPS, DHL and regional carriers. Claims & Disputes — lost, damaged and delayed parcels in one queue. Billing Lite — invoices, charge types and QuickBooks Online mapping, with real-time notifications. Reporting & Analytics — margin visibility per client, per carrier, per service level. Orbit AI runs across all six, answering operational questions in plain language rather than requiring a data pipeline. RocketFuel Recharge is not a warehouse management system and won't replace yours. It reads shipment and billing data from 146 connected systems: 111 warehouse management platforms including Deposco, ShipHero, ShipBob, Extensiv and Logiwa, 15 order and inventory systems including Cin7 and Finale Inventory, 11 shipping and carrier tools, QuickBooks Online for accounting, and 8 marketplaces including Amazon. It is also not a retroactive parcel audit tool. Auditing happens as labels print, not six months later when the money is already gone. RocketFuel Recharge is built for multi-client 3PLs with high USPS volume and $1M or more per month in parcel spend, running a warehouse management system they intend to keep. Typical buyers are 3PL owners, COOs, VPs of Operations and CFOs. It is not built for brands fulfilling their own orders, freight-forwarders with low parcel volume, or single-client captive 3PLs. Pricing starts at $500 per month with no seat fees. Built inside a 3PL, during peak season, by operators who had lived the cash-flow problem.

witn is billing infrastructure for teams shipping AI agents. When a product does real work for customers, taking an action, closing a ticket, booking a meeting, generating a lead, the billable event is the result, not raw tokens or seats. witn converts that result into invoiceable revenue. Agents emit raw product signals as they run. witn ingests those signals and evaluates them over time against a defined outcome, holds each outcome through a settlement window, monitors for anything that changes the picture, then finalizes. The output is one clean billable outcome per unit of work, fully auditable, with the complete event trail behind it. Every charge traces back to the exact signals that produced it and the moment it settled. No state to reconstruct from logs. No dispute without an answer.
