## Company Overview

- **Entity Type**: Private (Seed stage)
- **Headquarters**: San Mateo, California, United States
- **Founded**: Not publicly available
- **Founders**: Parijat Sarkar (CEO and Co-founder), Mitul Tiwari (CTO and Co-founder)

## Core Business

- Target customers: Mid-market to large enterprise finance teams (B2B)

## Products & Services
- **Strategic FP&A**: AI agent that explains every variance in seconds, generates custom reports, and uses natural language processing to uncover the "why" behind numbers.
- **The Continuous Close**: Automates the month-end close process by executing checklists, reconciling bank transactions, and calculating accruals with audit-ready documentation.
- **Accounts Payable**: Orchestrates AP workflows, from invoice routing to payment triage, optimizing outflows without manual bottlenecks.
- **Accounts Receivable**: Streamlines the AR lifecycle, including complex invoicing, intelligent dunning, and automated revenue recognition.

All products are delivered as a subscription SaaS platform that integrates natively with existing ERPs and systems of record. [numos.ai](https://www.numos.ai/)

## Market Standing

- **Auditability & Precision**: The platform is engineered for "absolute truth, auditability, and uncompromising accuracy," positioning it against "mostly accurate" competitors. [numos.ai](https://www.numos.ai/company)
