Deep tech companies are built around scientific or engineering breakthroughs. They focus on solving big, complex problems—like clean energy, advanced manufacturing, biotech, robotics, neurotech, aerospace, and more. These companies often take longer to develop because they’re tackling hard technical challenges, not just building software.
Absolutely. We specialize in deep-tech startups because their accounting needs are highly vertical, but the same AI platform and CPA support work just as well for SaaS, e-commerce, agencies, and other non-deep-tech businesses.
Our AI ingests receipts, invoices, payroll, and bank transactions, auto-categorizes 90-95 % of activity, posts compliant journal entries, and flags anomalies for accounting experts’ review, so your books stay accurate in real time.
A 30-minute screen-share captures read-only access to banking, credit cards, and payroll. Your Numix dashboard goes live within a week.
Your day-to-day team is a CPA-led pod of accountants and tax advisors with at least 15+ years combined experience; our AI simply supercharges their output.
Monday–Friday, 9 a.m.–6 p.m. PT. We aim to resolve most requests between 3 minutes and 2 business hours.

Yes. While some software-only tools stop at financial statements, Numix prepares and files your federal and state returns or coordinates seamlessly with your existing CPA.
1120 Corporate income tax (federal & state), Delaware franchise, 1099-NEC, and sales-tax reporting as needed; add-ons for multi-state registrations are available.
Absolutely—eligible startups typically recover ~10 % of qualifying R&D spend, averaging $50k per year. We handle the study and only charge if we save you money.
No. Loss-making startups can elect to offset up to $500k of payroll taxes with the credit.
All integrations are read-only and encrypted end-to-end; you can export or delete your data anytime, and we never sell user information.
Unlike pure-service firms, Numix delivers real-time financials, AI-accelerated close, and deep-tech-specific insights while still giving you access to seasoned accountants—no waiting weeks for month-end numbers.
