Expert Accounting Meets Operational Intelligence.
One Partner.
Most startups hire an accountant and separately piece together their operations stack. MATAX does both. And connects them. Investor-ready financials, automated workflows, and 20+ years helping startups scale.
300+ startups served · $800M+ in client fundraising supported · Up to 80% reduction in manual back-office tasks
MATAX is a San Francisco-based accounting and AI automation firm. Since 2006, we've helped more than 300 U.S. startups and scaling SaaS companies run cleaner books, smarter operations, and faster back-office workflows. Unlike traditional accounting firms, MATAX combines Xero-certified startup bookkeeping with custom no-code automation and agentic AI systems, so your financial data and your operational execution work together instead of in silos. We don't do taxes. We do transformation.

The Problems Every Scaling Startup Faces
Most early-stage companies share the same operational blind spots.
Your books are always behind
Your Series A close is in three weeks and your accountant just sent Q2 numbers. Your burn rate report is outdated. Your board wants a forecast you can't produce because last month's books aren't closed yet. Investors are asking questions, and you're scrambling instead of leading.
Your tools don't talk to each other
Stripe payments hit your bank but don't match Xero. Shopify orders sync to one system, but not to inventory or accounting. Your ops lead copies data from HubSpot to a spreadsheet, then pastes it into Slack. You have 12 tools and zero integration. Every handoff is a chance for errors.
Manual work drains your best people
Your head of finance spends 15 hours a week on data entry instead of strategy. Your ops manager manually sends invoice reminders, updates project trackers, and generates reports that should build themselves. You hired smart people, then buried them in busywork.
No real operational visibility
A board member asks your customer acquisition cost and you need two days to calculate it. Your co-founder asks about cash runway and gets a different number from three sources. You can't see burn rate, revenue trends, or project profitability in one place, so every decision feels like a guess.
There's a better way. Let's build it.
AI Is Everywhere. Systems Thinking Is Rare.
Every startup has access to the same AI tools. The difference is whether those tools are connected to clean financial data, proven workflows, and experienced oversight. The startups that win in 2026 aren't running the most tools. They're the ones with the right foundation, the right systems, and the right partner tying it all together.
That's what CoreOps™ is: accounting infrastructure at the foundation, intelligent automation in the middle, and real-time visibility at the top. Built by a team that's done it 300+ times over 20 years.
