What is Synthetic?

Synthetic was founded in November 2025 and is headquartered in San Francisco. It is building AI-led bookkeeping for a narrow group of software startups and is currently available through a waitlist and limited prototype access.

Synthetic is an agentic bookkeeping service designed to complete accounting work rather than provide another interface for a founder or bookkeeper to operate. Customers connect bank accounts, payroll, billing systems, business tools, and inboxes. The system reads business context, categorizes and reconciles transactions, asks clarifying questions, and produces accrual-basis books, financial reports, and management outputs that can be exported to a tax preparer.

The workflow covers automated transaction categorization and reconciliation, journal entries, management reports, dashboards, workflow tasks, and autonomous requests for clarification or documentation. Public materials do not identify specific software connectors, an API, accuracy metrics, uptime commitments, or accounting assurance. Synthetic also states that its personnel do not independently audit, review, or verify AI-generated bookkeeping outputs, leaving reliance decisions with the customer.

Synthetic targets software, SaaS, and AI startups rather than the broader small-business bookkeeping market. It is waitlist-only or limited early access as of November 1, 2026, with reporting describing the product as a prototype still being tested with a narrow user group. Pricing is planned to start at $49 per month, but the company has not published purchasable plans, contract terms, limits, or trial terms.

No public connector directory, API, SDK, or named financial-data vendor list is available.

Who is Synthetic for?

Is Synthetic's bookkeeping independently reviewed or certified?

+

Synthetic's privacy policy says its personnel do not independently audit, review, or verify AI bookkeeping outputs, so customers decide whether to rely on them. Public materials reviewed do not document a SOC 2 or ISO certification, independent accounting assurance, accuracy metric, or public audit report.
