Operations Platform AI, SaaS & digital platforms
Aretai
One workspace for operations: people, time, projects and invoicing, with an AI agent built in.
Aretai is Valens's own product: an operations platform for agencies and delivery teams that staff, track and bill their time. Leave, time sheets, projects, estimates and client invoicing live in one workspace, and an AI agent audits time entries, sends reminders and drafts invoices.
The problem
Services teams run people, time, projects and invoicing across disconnected tools, so hours slip and invoices go out late.
Our delivery
One workspace for leave, time sheets, projects, estimates and invoicing, plus an AI agent that audits entries, sends reminders and drafts invoices, on demand or on a schedule.
How we worked
Project context
Aretai is a startup built and run by Valens, for agencies and delivery teams who staff, track and bill their time. It replaces a stack of disconnected tools with one workspace that covers people, time, projects and invoicing.
Delivery scope
Valens owns the whole product: product strategy, UX/UI design, frontend and backend development, AI agent features and quality assurance.
How we built it
Aretai runs on Next.js and NestJS with a PostgreSQL database. Subscriptions are billed through Stripe, Slack and Discord are connected, and time and billing data exports to client-ready PDF and Excel files. The interface is available in six languages. The built-in AI agent, powered by Claude models, searches workspace data, audits time entries, sends reminders and drafts invoices, either on request or on a schedule.
