The lease ran to 70 or 80 pages. The accountant wanted only a few facts. Between those two numbers lay the peculiar misery of modern finance: a contract written for lawyers, a balance sheet written for investors, and a person asked to carry meaning from one to the other without dropping a decimal. At Bradken, the Australian manufacturer, that person had a low opinion of its previous lease software. Group financial accountant Morgan Hoffmann said the team felt it could do the work “nearly ... in Excel just as good.” For a paid system, that is a fairly devastating review.
- Trullion reads financial documents and connects extracted facts to accounting calculations and audit evidence.
- Its customers include corporate finance teams and audit firms; the company reported more than 3,000 company customers in 2025.
- Bradken says it cut lease reporting time by 25% and software cost by 30% after switching.
- The useful test is whether a reviewer can get from a reported number back to the clause that created it.
Bradken tried Trullion on one of its own contracts. The demonstration worked because it attacked the small, maddening task at the heart of the job: finding the handful of lease terms that change the accounting. The company then moved its lease portfolio onto the platform. Hoffmann estimates the team now spends 25% less time on reporting and pays 30% less for software than it did before. Those are Bradken’s reported results, not a promise for every lease portfolio. The more revealing change may be that its auditors can log in and inspect the contracts and schedules themselves.
A number with a return address
Trullion’s first problem was lease accounting. Under ASC 842 and IFRS 16, companies must turn commitments buried in property and equipment contracts into balance-sheet entries, schedules, journal entries and disclosures. A lease changes; the schedule changes. Someone signs an amendment late; the previous month’s work may need catching up. The details travel through PDFs, spreadsheets and enterprise systems, each with its own talent for being almost, but not quite, current.
The company’s software extracts contract terms, keeps them linked to the source, and uses them in accounting workflows. That link matters. An AI model that produces a lease term quickly is useful; a model that lets an accountant check the sentence it read is much more useful. The gap between the two is the gap between a plausible answer and an auditable one. Trullion has made that gap its commercial territory.
Isaac Heller and Amir Boldo founded Trullion in 2019. Heller led it as CEO until 2025; Boldo is its co-founder and CTO. The business grew from a lease product into a platform serving accountants, controllers, CFOs and auditors. Its other product areas now include revenue assurance, automated audit tests, financial statement validation and Trulli, an AI assistant introduced in 2025. The assistant can answer questions about policies and documents, but Trullion’s own description puts the audit trail behind every answer. That is a more demanding job than making a chatbot sound confident.
The spreadsheet is a formidable incumbent
The obvious competitor is Excel, which is cheap, familiar and astonishingly hard to dislodge. Specialist lease systems compete for the same budgets. In audit, DataSnipper speeds document matching and review inside Excel; Trullion argues for a connected environment that also covers leases, revenue and shared evidence. That distinction is practical rather than philosophical. If the job is one well-defined spreadsheet task, an add-in may be enough. If the same contract must feed an accounting schedule, a reconciliation and an auditor’s workpaper, the handoffs become the product.
This is also why Trullion sells to two parties who often spend their days asking each other for the same files. A corporate controller needs to close the books. An external auditor needs to test the numbers and retain evidence for a later reviewer. Giving both parties controlled access to the underlying document can save a familiar ritual: request, search, attach, question, search again. The platform is sold as business software through demos and subscriptions. It does not publish a general price list; the economic case rests on the work a particular team can remove, and the cost of getting its documents and systems into shape.

Bradken’s experience offers a useful buying method. It did not start with a grand claim about transformation. It put its own contract into the demo, examined the extraction, looked at the reporting, and compared the result with the old system and with Excel. The team also cared that reports lined up with general-ledger movements, a detail that rarely appears in an AI advertisement and frequently appears in an auditor’s question.
From the lease to the audit file
The expansion into audit follows the same document logic. Tanner, a Utah accounting firm, initially used Trullion for optical character recognition and detail testing. It later added revenue testing, financial statement tie-outs and extraction from lease and debt agreements. Tanner says time spent on manual audit tasks fell by up to 50%. That figure belongs to a customer case study, and the phrase “up to” matters. Even so, the sequence tells a concrete story: begin where staff repeatedly copy, compare and check; then extend the workflow only when the output can survive review.
The 2026 Thomson Reuters partnership takes that logic into an auditor’s existing workspace. Within Guided Assurance, a flagged financial statement can be checked by Trullion for arithmetic, internal consistency, draft changes and year-over-year movements. A completed workpaper with PPC citations returns to Thomson Reuters Engagement Manager. Auditors still decide what a discrepancy means. The software gets the mechanical checks and their documentation in front of them.
This is Trullion’s position in the market: more specialized than a general AI assistant, broader than a single-purpose lease calculator, and intent on connecting the office of the CFO with the audit firm. It is backed by venture capital, including $15 million raised in 2022 and a further $15 million in 2023. In October 2025, the company said it served more than 3,000 companies worldwide and appointed Artie Minson CEO. Heller became president and remained board chair, focusing on product and partnerships. The company has teams in New York, Tel Aviv and London.
Where the machine should stop
A good accounting system cannot make a weak contract clear by decree. It needs readable source documents, correct entity and ledger data, sensible review rules and people willing to resolve exceptions. A company with only a few simple leases may find its spreadsheet adequate. An audit firm that only needs a narrow Excel workflow may prefer a narrow tool. And no amount of automated footing decides whether management’s accounting judgment is defensible.
That limit is part of the appeal of the idea. Trullion is trying to make the routine trip from source to statement shorter, and the trip back possible. In finance, the second journey is the one that counts. A number in a report can look splendid by itself. Ask where it came from, and it had better have an answer.
