Ian Crosby has spent years rebuilding his reputation after Bench, the startup bookkeeping app he co-founded in 2012, collapsed in early 2023 Bench. Now he’s back with Synthetic, a new company that just raised $10 million from Khosla Ventures to build an AI system that does all the work of bookkeeping without a single human in the loop. The service is already live in beta for a small group of startup customers, and Crosby says it’s handling everything from invoicing to tax filings on its own.

Crosby isn’t reinventing bookkeeping from scratch. Synthetic’s software plugs into a startup’s bank accounts, credit cards, and other financial tools the same way Bench did. But instead of relying on human bookkeepers to review transactions and categorize expenses, Synthetic uses its own AI models to make those calls in real time. The company claims it can close monthly books in minutes and file taxes automatically, cutting the usual week-long process down to hours. For startups that live or die by cash flow, faster and cleaner financials matter a lot.

Why Crosby’s second shot might stick this time

Bench’s downfall wasn’t about the idea—it scaled to tens of thousands of customers and raised nearly $80 million. The problem was execution. The company struggled with customer service as it grew, and by the time it shut down, it had laid off hundreds of bookkeepers and left customers scrambling for alternatives. Crosby says Synthetic’s biggest advantage is that it doesn’t need any bookkeepers at all. The AI handles mistakes by learning from them and adjusting its rules, not by adding more humans. The company’s pitch is simple: no errors, no delays, no expensive service fees.

Khosla Ventures partner Jitendra Malik led the investment and told TechCrunch the firm was betting on Synthetic because it solves a real pain point for startups. “Founders don’t want to spend weeks every month reconciling books or arguing with their accountants,” Malik said. “They want financial clarity yesterday.” The round also included existing investors Index Ventures and a handful of angel investors who had backed both Bench and Synthetic.

How the AI actually works day-to-day

Synthetic’s system is built on a mix of large language models and traditional accounting rules. When a new transaction hits a customer’s bank feed, the AI first checks it against the company’s past behavior. If it’s a recurring SaaS expense, for example, the system auto-categorizes it as “software” and marks it as billable if the customer has set that rule. For one-time payments, the AI flags anything unusual—like a $10,000 charge from a vendor it doesn’t recognize—and asks the founder to confirm via Slack or email. Most of the time, it just does the work without bothering anyone.

The company’s dashboard looks like a stripped-down version of Bench’s old interface, but with fewer buttons and more automation. Founders can see their runway, burn rate, and tax deadlines in one place. The AI even drafts the notes that go into a startup’s cap table when it raises money, pulling numbers straight from the books. Crosby says the goal is to make financial management feel like it’s happening in the background, not in a monthly panic before investor meetings.

What could go wrong—and who’s watching

The biggest risk is accuracy. Even the best AI can misread a receipt or misclassify an expense, and in bookkeeping, one wrong number can ripple through an entire financial model. Synthetic’s team says it has built in guardrails: every AI decision is logged, and founders can audit changes or override them manually. The company also offers a “human review” option for customers who want a second set of eyes, though Crosby admits most startups will skip it to save money.

Regulators are another wildcard. The IRS and state tax agencies don’t love fully automated tax filings, especially when the software makes the call on deductions or credits. Synthetic says it works with licensed CPAs to review its tax logic, but the ultimate responsibility still falls on the startup’s founders. Crosby is quick to note that Synthetic isn’t a replacement for a CFO—it’s a tool for startups that can’t afford one yet. For now, it’s targeting early-stage companies with under $5 million in annual revenue, the same market Bench once dominated.

Crosby’s comeback story is still early innings. Synthetic has about 100 customers so far, all startups that were burned by Bench or never trusted it in the first place. The $10 million will mostly go toward scaling the team and improving the AI’s accuracy. Khosla’s bet is that founders are tired of waiting weeks for clean books. If Synthetic delivers, it could force every bookkeeping startup to rethink how they build software—and how they treat their customers.

🇧🇷 Resumo em Português

O vale do silício volta a apostar no empreendedorismo brasileiro com um novo round de investimento milionário, desta vez em uma startup de contabilidade com inteligência artificial que promete revolucionar o mercado de pequenas e médias empresas. A Synthetic, fundada por Ian Crosby — que já havia tentado emplacar a Bench, empresa que não vingou anos atrás — acaba de levantar US$ 10 milhões com o apoio da renomada Khosla Ventures, sinalizando um novo ciclo de inovação no setor financeiro automatizado.

A chegada da Synthetic ao Brasil chama atenção não só pelo valor do investimento, mas pela proposta de usar IA para simplificar a gestão contábil de negócios, um desafio crescente em um país onde milhões de empreendedores ainda lidam com burocracia e planilhas complexas. Enquanto o Brasil enfrenta uma demanda crescente por soluções tecnológicas que desburocratizem a administração de empresas, a startup chega com um modelo que pode atrair desde microempreendedores até médias empresas, setores que representam cerca de 30% do PIB nacional. A aposta da Khosla Ventures reforça a tendência de que o país pode se tornar um polo de inovação em serviços automatizados, mesmo após fracassos anteriores no segmento.

Se o novo empreendimento de Crosby emplacar, pode não apenas reabilitar sua trajetória no mercado, mas também mostrar que o Brasil e a América Latina estão prontos para absorver soluções de IA que tornem a contabilidade acessível e eficiente para todos.
