Khosla Ventures committed $10 million to fund Synthetic, an AI bookkeeping startup led by Ian Crosby, who previously founded Bench, a venture-backed accounting software company that ultimately failed. Crosby's new venture takes a different approach, building a fully autonomous AI system to handle bookkeeping tasks for startups rather than relying on a hybrid human-software model.
The $10 million bet reflects confidence that Crosby learned from Bench's collapse and can execute better the second time. Synthetic targets a real pain point: most founders hate managing books and outsourcing to accountants costs thousands monthly. An autonomous system that handles reconciliation, categorization, and basic accounting work could undercut traditional services while requiring minimal startup involvement.
Autonomous bookkeeping sits at the intersection of AI capabilities maturing enough for specialized financial tasks. Large language models and machine learning can now process transactions, identify patterns, and categorize spending with reasonable accuracy. Synthetic differentiates from Bench by removing the human accountant component entirely, letting AI own the workflow instead of augmenting it.
The risk is real. Accounting errors compound fast, and automated mistakes could expose startups to tax liability or audit problems. Regulatory scrutiny around AI-driven financial services may intensify. Building trust in autonomous systems handling money remains harder than building trust in software that just suggests what to do.
Crosby's track record cuts both ways. Bench proved he understands the market deeply. Its failure suggests he understands what didn't work. Khosla's wager bets that understanding translates into building something better with current AI capabilities. Synthetic enters a crowded space including Stripe's financial infrastructure push and niche players, but the fully autonomous angle offers a distinct positioning if execution lands.
