Trullion

Founder Isaac Heller leads the company, supported by a team of former Big Four CPAs who design the platform's accounting logic. Public materials do not identify a separate CTO or CPO by name, but the Tel Aviv office houses core engineering. The firm's about page emphasizes that its industry experts are former practitioners who lived the manual audit and accounting workflows the software replaces.

Trullion builds its knowledge layer from public accounting standards — ASC 842, IFRS 16, and GAAS audit requirements — combined with customer-contracted document patterns. The platform's AI agents are trained to extract terms from lease agreements, audit evidence, and financial statements specifically, which differs from general-purpose document AI tools. The firm cites this domain-specific grounding as the reason its outputs are auditable rather than black-box.

Trullion is a pure software provider. It sells a SaaS platform to enterprise finance teams and external audit firms but does not perform audits, provide accounting opinions, or offer managed services. Its model competes with point solutions and manual spreadsheet workflows, not with CPA firms' attest or advisory practices.

Trullion's core domain is lease accounting, covering real estate leases and equipment leases under ASC 842 and IFRS 16. It also extends to audit fieldwork, internal audit evidence testing, and document-heavy finance transformation work. The platform is not positioned as a general ERP and does not natively address inventory, revenue recognition, or payroll accounting today.

The firm does not publish a customer list, logo roster, or total revenue number. Testimonials on its website reference teams that reduced manual lease-accounting time by over 25 percent and cut software costs by over 30 percent when switching from a prior tool, but neither the prior tool nor the customers are named. There is no public funding or valuation disclosed.
