Khosla Ventures Invests $10M in Synthetic, an AI Accountant From Bench's Founder

Venture fund Khosla Ventures has put $10 million into Synthetic, a project from Ian Crosby, the founder of Bench, a service that shut down several years ago. This time Crosby is building an AI service that fully automates bookkeeping for young companies.

What is Synthetic

Synthetic is an AI agent that takes over a startup's bookkeeping entirely. It needs neither accountants nor endless integrations with the fintech ecosystem. The agent connects to bank accounts and payment systems, works out which expenses belong to which categories, and generates the necessary reports.

Features include:

• Full accounting automation from scratch (from creating invoices to closing the period)
• Reading and analyzing bank statements and payment transactions
• Automatic classification and categorization of expenses
• Preparation of tax returns and financial reports
• Integration with major payment systems and banks

It is not the first AI accountant product in this category. But Synthetic positions itself as fully autonomous, with no human involvement.

Why Khosla gave Crosby the money

Bench, Crosby's first startup, was an attempt to make bookkeeping simple. It raised tens of millions in funding and looked successful, but ultimately shut down. It was a failure worth hundreds of millions of dollars.

Yet here is the paradox: Khosla Ventures, one of the more conservative venture funds, committed $10 million to a new project from the same person. That suggests several things. First, investors believe Crosby learned his lessons. Second, they see huge potential in the AI bookkeeping market. Third, even failure does not destroy a founder's reputation in Silicon Valley, as long as an investor believes in the idea.

Context: the automation market is growing

Accounting is a classic field for automation: routine, rules, predictable processes. AI handles tasks that require understanding structured documents and logic very well. Startups need this especially: they cannot afford a staff accountant, but they must keep their books and pay taxes.

Synthetic is riding a wave of demand. If it proves reliable, it could become the standard for thousands of young companies.

What this means

Khosla's investment is a signal to the market: startup accounting is moving to AI. For founders of young companies, this could mean real savings on payroll and simpler operations. For Crosby himself, it is a second chance, a rare thing in venture capital, where one mistake usually ends a career. And for Khosla, it is a potential billion-dollar exit if Synthetic becomes the standard in its category.
