Every finance lead at an early-stage company knows the drill: you close the books three weeks after the month ends, spend hours hunting down mystery transactions across five different systems and random Excel files, and by the time you finally have clean numbers, they're already old news. Your FP&A dashboard shows ARR, you’ve got GAAP revenue from your general ledger, and somewhere in between, your revenue model breaks for the third time this quarter.

‍

This is the reality for most finance teams. The tools haven't kept up. You're making real-time decisions based on weeks-old data, and your team spends more time reconciling spreadsheets than actually analyzing the business.

‍

Quanta is rebuilding accounting from scratch. Today, the company announced its $15M Series A and launched Prism, an AI-powered reporting layer that lets finance teams actually talk to their books.

‍

The Company

Quanta is building an AI-first accounting platform purpose-built for software companies. Here's what makes it different: Quanta’s ledger is built from scratch to harmonize finance and accounting. The platform ingests data directly from your existing stack (or can replace it!), applies policy, posts entries, and reconciles continuously. Automation handles the grunt work. Quanta’s in-house accounting team catches the exceptions and applies human judgment. Together, they keep your books accurate and current, not just at month-end, but throughout the entire month.

‍

Why You Should Pay Attention

The standard playbook for early-stage companies goes something like this: start with QuickBooks, spend weekends doing manual reconciliations, eventually hire an expensive outside contractor who still takes three weeks to close, then graduate to an enterprise ERP that costs a fortune, takes months to implement, and moves just as slowly. At every stage, you're waiting on the books to catch up to the business.

‍

79% of finance leaders say their teams are drowning in manual work. Quanta's approach cuts through this by owning the accounting end-to-end rather than adding another layer to an already messy stack. The platform provides comprehensive services covering everything from bookkeeping and controller services to tax filing, all delivered through their AI-powered platform paired with expert accounting support. It’s the best of both worlds. 

‍

The Details

Quanta's foundation is its continuously reconciling accounting engine. Every transaction is classified, reconciled, and updated in real time. Automation handles the repetitive work while the in-house accounting team works within the same environment to review exceptions and preserve human judgment. This creates what founder and CEO Helen Hastings calls "explainable finance" - where the system that creates the numbers becomes the system that explains them.

‍

That's where Prism comes in. It's an agentic AI layer that sits on top of Quanta's verified data and can answer questions like a teammate who actually knows your books inside and out. Want to know your true margin by product? How LLM API costs shifted last quarter? Churn by customer segment? Ask Prism. Unlike typical AI tools that hand you an answer and shrug when you ask "how?", Prism shows its work. Every answer traces back to the underlying transactions.

‍

The platform addresses several key pain points that plague finance teams:

• Real-time accuracy: No more waiting weeks for close. The books stay current throughout the month.
• Traceability: Every number carries its lineage as structured data. Finance teams can trace any metric back to its source.
• Intelligence: Prism transforms verified accounting data into a live view of how the business actually runs, answering complex financial questions instantly.

For companies in the AI era where margins are tight and costs swing weekly, this matters. Real-time finance isn't a nice-to-have anymore.

‍

Why We're Invested

Founder & CEO Helen Hastings lived the problem firsthand as a software engineer at Affirm, where accounting systems produced reports once a month through highly manual processes. She knew there had to be a better way. After working with her for two years through our supporting investment in Quanta's seed round, we've watched the AI-first approach gain serious traction.

‍

Accounting isn't known for moving fast on innovation, and the ERP space is crowded. But Quanta's Series A gives them the runway to capture a real opportunity. By owning the ledger and building intelligence on top of clean, verified data, they're creating something that didn't exist before: a system where finance teams can operate on live, explainable data instead of spreadsheets and stale reports.

‍

What's Next

With this Series A, Quanta plans to double down on its accounting engine, expand the expert services team, and accelerate development of Prism's intelligence layer. The goal is a world where books stay continuously accurate and finance teams have real-time visibility into what's actually happening.

For companies tired of waiting weeks for close and making big decisions on old numbers, Quanta offers something different: accounting that actually keeps up.
