Reinventing the Financial Stack
Numbrr.ai is AI bookkeeping software for US startups and small businesses, made by Numbrr.ai LLC in New York. It started from a simple observation: startups need more than a spreadsheet, and they need it at a price below accountant-hourly rates.
Our AI handles categorization, matching, and reconciliation, and sends anything it is unsure of to a review queue. When you want a person reviewing your books every month, add the optional Dedicated Controller. It helps most when the stakes go up: a fundraise, tax season, or an audit.
Our Mission
To deliver world-class, cost-effective financial support for startups and small businesses through automation, AI, and disciplined oversight, with a SaaS-like experience that combines accuracy, transparency, and efficiency. Every founder deserves Fortune 500-grade financial clarity at a price a startup can afford.
Our Vision
To become the leading financial operating system for startups and small businesses: one source of truth for SMB financial data, with bookkeeping, invoicing, bills, and reporting in one intelligent platform.
What We Do
Numbrr is AI bookkeeping software that also e-files your 1099s. When you want a person on your books, add the optional Dedicated Controller.
AI Bookkeeping
Automated transaction categorization, OCR-based invoice processing, and month-end close routines, all run fully by AI. Add a Dedicated Controller any time you want a person reviewing your books.
- Accrual books on every plan
- Monthly reconciliation
- Tax-ready year-end package
- Monthly close in minutes
1099 Filing
Numbrr tracks what you pay each contractor, requests their W-9s, and e-files your 1099s. At year end, your preparer works from books that already tie.
- 1099 e-filing
- W-9 requests
- Contractor payment tracking
- Year-end books for your preparer
Dedicated Controller
An optional add-on: one controller assigned to your account. Each month they review your books, work through anything the AI flagged, and check your monthly reports before sending them to you. They also help you move over from your old system or bookkeeper, and they are the person you go to with questions.
- Monthly review of your books
- AI-flagged exceptions handled
- Monthly reports reviewed and sent
- One point of contact

The Problem We Set Out to Fix
Traditional accounting was built for a different era. We're replacing it with something built for how founders operate.
The Old Way
- ✕Hourly billing — unpredictable invoices every month ($60-$120/hr)
- ✕Reports delivered weeks after month-end
- ✕No real-time view of burn rate or cash flow
- ✕Rotating bookkeepers with no institutional knowledge
- ✕DIY software that's complex and error-prone for non-accountants
- ✕Fragmented vendors for books, tax, and financial strategy
The Numbrr.ai Way
- ✓Flat monthly pricing
- ✓Books closed in minutes
- ✓24/7 live dashboard with real-time financial visibility
- ✓Fully AI bookkeeping, with a controller added if and when you need one
- ✓AI handles the data entry, every day, automatically
- ✓Bookkeeping, 1099 filing and a Dedicated Controller under one roof
