Quanta, the accounting platform built to keep startup finances continuously accurate, today announced its $15 million Series A led by Accel, with participation from Operator Collective, Naval Ravikant, Designer Fund, Basecase, and operators including Akshay Kothari (Notion), Claire Hughes Johnson (Stripe), and Huey Lin (Affirm). The funding coincides with the launch of Prism, the new AI-powered reporting layer of the Quanta Platform, and a key step toward the company’s goal of creating a continuously closing, explainable system of record for modern finance.
Every early finance lead knows the operational reality: even with modern tools, much of the work still happens manually. Small finance teams routinely spend hours each week validating transactions, rebuilding reports, and reconciling inconsistencies across systems — a problem reflected across the industry, where 79% of finance leaders say their teams are swamped with manual tasks. Most accounting platforms still lag behind the business weeks; FP&A dashboards depend on inconsistent or delayed data; and outsourced bookkeeping services often return books with limited context behind the numbers. The result is a familiar one: models that break often, ARR reports that diverge from the accounting, and decisions made on stale or incomplete information.
Quanta addresses this by rebuilding the accounting foundation itself. The company is the only system of record that performs the accounting internally — combining automation with a dedicated accounting team to classify, reconcile, and ensure the accuracy of every transaction. This blended model ensures that every number is both current and trustworthy, giving finance teams a materially accurate base to operate from throughout the month, not just at close.
Finance leaders say that foundation has changed how they work. “The efficiency gains since partnering with Quanta have been remarkable. We’ve cut our close time by 85%, and the fact that the data stays accurate and traceable means we’re not constantly fixing discrepancies or rebuilding reports,” said Chris Burgner, head of finance at Equals, “When you can see the context behind the numbers, it’s much easier to trust what you’re looking at, understand what changed and why, and explain it to the rest of the business.”
“Our belief is simple: finance teams deserve a system that keeps up with the business,” said Helen Hastings, co-founder and CEO of Quanta. “By handling the accounting ourselves, with automation for speed and experts for quality, we’re able to give teams a foundation they can trust. When the accounting is already correct, everything else becomes faster and more dependable. That’s what makes Prism possible. It reasons through that data to answer questions directly and show the steps behind each answer.”
It does this through an agentic AI layer that can reason through the data and answer questions directly. Prism gives teams the ability to explore their verified data instantly and understand how each report is constructed. Unlike tools that rely on fragmented or delayed inputs, Prism provides sourced, auditable results that show their work. Teams can ask questions such as “What’s our margin by product?” “How did LLM API costs change last quarter?” or “What is churn by segment?” and receive structured, defensible answers tied directly to the underlying books. Prism turns reporting from a static export into an explainable layer of intelligence.
“AI is only as good as the data behind it,” said Amit Kumar, partner at Accel. “Quanta’s approach is powerful because they rebuilt the accounting foundation first. Prism sits on top of clean, continuously maintained data, giving finance teams answers they can trust — not black-box guesses.”
Unlike tools that sit on top of legacy general ledgers or outsourced bookkeeping, Quanta unifies accounting, accuracy, and understanding in one continuously reconciling environment. The platform performs the accounting. The team ensures every exception is resolved. And Prism makes the results instantly interpretable. Together, they bring finance closer to a live, fully traceable state, where every number is sourced, connected, and able to explain itself.
With this Series A, Quanta plans to deepen this foundation — investing in its accounting engine, expanding its expert services team, and accelerating development of Prism’s intelligence layer. The company is advancing toward a world where the books stay continuously accurate, and finance teams can operate on live, explainable data.
