Khosla Ventures has invested $10 million in Synthetic, a new startup by Ian Crosby aiming to create fully autonomous AI bookkeeping.

Khosla Ventures has invested $10 million in Synthetic, a startup founded by Ian Crosby to develop fully autonomous AI bookkeeping technology, despite Crosby’s previous startup, Bench, collapsing in 2024.
The seed funding round was led by Khosla Ventures, with participation from Basis Set Ventures and Shopify CEO Tobias Lütke. Crosby’s new company aims to automate bookkeeping entirely, generating accrual-based financials without human input, although the product remains in the design stage.
Crosby’s previous startup, Bench, filed for insolvency in 2024 after a period of financial decline, and Crosby was ousted from the company in 2021. Despite this, Khosla partner Jon Chu expressed confidence in Crosby’s potential, citing his willingness to take risks and learn from past mistakes.
Crosby emphasizes that Synthetic’s goal is to create a fully autonomous system, though he admits current AI models still make significant errors. He compares the technology’s development to a self-driving car that can navigate a single street versus any street, acknowledging the technical challenges ahead.
Why It Matters
This investment highlights a willingness among venture capitalists to back high-risk, high-reward AI innovations despite founders’ previous failures. It also signals a potential shift in the accounting industry toward fully automated solutions, which could disrupt traditional firms reliant on human accountants.
For readers, this underscores the ongoing evolution of AI in enterprise services and the appetite for bold ventures even when past ventures have failed, reflecting both the risks and opportunities in AI-driven startups.

Background
Ian Crosby’s previous startup, Bench, was a prominent online accounting platform that struggled with financial sustainability and was ultimately sold for parts in 2024. Crosby’s departure from Bench followed disagreements with the board, and the company’s subsequent collapse was attributed to management issues and market challenges.
After Bench, Crosby joined Shopify and founded Teal, which was acquired by Mercury within 18 months. His recent focus has been on developing AI technology capable of fully automating bookkeeping tasks, an area with significant technical hurdles but high potential for disruption.
“I tend to run towards controversy a little bit. In controversy, groupthink often shapes the narrative rather than the truth of the story itself.”
— Jon Chu, Khosla Ventures partner
“We’re not going to release anything that’s not fully autonomous. It’s that or bust.”
