Trullion

Trullion was founded in 2019 by Isaac Heller, who assembled a team of former Big Four CPAs to build an AI platform that automates core accounting and audit workflows. The firm is headquartered in New York, with engineering presence in Tel Aviv and a commercial office in London. Its early focus was lease accounting under ASC 842 and IFRS 16, but the platform now spans audit testing, internal audit evidence reconciliation, and broader finance transformation workflows. The platform operates as a vertical AI layer that ingests structured and unstructured data — extracting lease terms from PDFs, recalculating schedules, and flagging inconsistencies. Trullion sells to enterprise finance teams and external audit firms, covering asset classes that include real estate leases, equipment leases, and financial document testing. The software targets stages from pre-close preparation through post-audit reporting. While Trullion does not disclose a client list, its public testimonials reference teams that migrated from competing lease-accounting tools and reduced manual reporting time by over 25 percent. The firm has not disclosed its total deployment or professional headcount. It maintains engineering operations in Tel Aviv and a commercial footprint in London, in addition to its New York base. Public statements do not confirm adjacent vehicles, philanthropic foundations, or club-deal structures. No recent operational event within the last 24 months was verifiable from available firm disclosures. Trullion's architecture treats the accounting general ledger as a source of structured truth and surrounds it with agents that read contracts, test entries, and produce audit-ready workpapers. That design turns an auditor's judgment — not just their rote tasks — into a scalable software layer, structuring the firm around a belief that accounting's AI era will be vertical-specific rather than a horizontal add-on to existing ERPs.
