- • Synthetic aims to build a fully autonomous AI bookkeeper capable of generating accrual-based financial statements without direct human involvement, though Crosby acknowledges the technology may not yet be feasible.

- • Khosla partner Jon Chu justified the investment despite industry skepticism, noting he "runs towards controversy" and citing Parker Conrad's Zenefits-to-Rippling trajectory ($17 billion valuation) as precedent for backing founders through difficult narratives.
- • The funding decision reflects a calculated bet on founder resilience and the addressable market for AI-driven bookkeeping automation, despite acknowledged technical risks.
Summary
Ian Crosby, founder of the defunct Bench Accounting, has secured $10 million in seed funding for his new startup, Synthetic, which targets the bookkeeping automation market with an AI-first approach. The round was led by Khosla Ventures with co-investment from Basis Set Ventures and Shopify CEO Tobias Lütke, signaling notable institutional confidence despite Crosby's recent operational setback.
Synthetic's core proposition centers on building a fully autonomous AI bookkeeper that can generate accrual-based financial statements without requiring direct human intervention. However, Crosby has been transparent about the venture's technological risk profile: the product remains in the design phase, and he acknowledges that his vision may exceed current foundational model capabilities. This candor appears to have resonated with Khosla's investment thesis rather than deterred it.
Crosby's previous company, Bench Accounting, imploded in 2024 after a tumultuous operational period. Notably, Crosby was ousted by Bench's board in 2021—three months after rejecting a $250 million acquisition offer from Brex. Board disagreements centered on strategic direction as the business hemorrhaged cash, with executive leadership reportedly frustrated by Crosby's direct management style. Despite this failure, Crosby maintains he was not directly responsible for Bench's insolvency, framing his departure as a disagreement over company trajectory rather than personal mismanagement.
Khosla partner Jon Chu articulated the firm's contrarian stance, stating he tends to "run towards controversy a little bit" because "groupthink often shapes the narrative rather than the truth of the story itself." Chu cited Parker Conrad's path—ousted from Zenefits in 2016 amid industry criticism, only to build Rippling into a $17 billion valuation—as a precedent for backing founders through reputational headwinds. "I believe people have room for growth," Chu said regarding his conviction in Crosby and Synthetic. This investment reflects a deliberate strategy to identify founder resilience and market opportunity beneath contested narratives, rather than following consensus dismissal of troubled track records.
