Overview

Synthetic: An AI Agent for Startup Bookkeeping

Synthetic is an AI agent that handles startup bookkeeping from start to finish — connecting to bank, payroll, and business tools, reconciling transactions, and producing accrual-basis reporting that is ready for tax. Rather than a dashboard the founder still has to operate, Synthetic does the work and asks clarifying questions only when it genuinely needs input, aiming to remove bookkeeping as a task rather than make it easier.

It is built for startups that want clean, accrual-basis books without hiring a bookkeeper or wrestling with accounting software.

Key Features

  • Automated bookkeeping and reconciliation
  • Bank, payroll, and business-tool integrations
  • Accrual-basis reporting
  • AI clarifying questions instead of busywork
  • Tax-ready exports
  • No learning curve

Ideal Use Case

Synthetic fits startups and small companies that need accurate, accrual-basis books but do not want to hire a bookkeeper or manage accounting software themselves. It suits founders who would rather not think about bookkeeping at all.

How Synthetic differentiates

Synthetic aims to do bookkeeping autonomously end to end, asking questions only when needed, rather than being software the founder operates. It is backed by Khosla Ventures and founded by Ian Crosby, who previously built a large SMB bookkeeping service.
