Complete oversight of your financial operations and compliance
Deep-dive execution for critical financial milestones
I embed myself in your team, understand your business deeply, and take ownership of your financial success - from day-to-day operations to strategic milestones.
Unlike large fractional CFO firms that spread one person across many clients, I maintain a select portfolio. You get my full attention and expertise - not a junior associate.
Dual US-Israel CPA with deep understanding of both ecosystems. Perfect for Israeli startups with US operations or global ambitions.
I leverage automation and AI tools to deliver faster insights and streamline financial processes - modern solutions for modern companies.
I'm available when you need me - responsive and accessible. No waiting weeks for a response or being shuffled between team members.
I'm Amir Sarig, a dual US-Israeli CPA with an MBA in Finance and over 20 years of experience in financial leadership.
Whether you're preparing for a fundraise or managing day-to-day operations, I take full ownership of your financial function. From monthly closes and cash flow management to board reporting and investor relations - I handle it all so you can focus on building your product and growing your business.
My approach combines strategic thinking with hands-on execution. You get the expertise of a full-time CFO with the flexibility of a trusted partner who's there month after month, not just during fundraising sprints.
Ready to take your startup's finances to the next level?
A fractional CFO is a part-time chief financial officer who provides strategic financial leadership to companies that need CFO-level expertise but aren't ready for a full-time hire. Unlike consultants who advise from the sidelines, a fractional CFO embeds in your team and takes ownership of financial outcomes — from fundraising strategy to monthly closes.
Israeli startups should consider a fractional CFO when preparing for Series A fundraising, when monthly burn exceeds $50K, when IIA (Israel Innovation Authority) compliance becomes complex, or when the CEO is spending more than 20% of their time on financial operations instead of product and growth.
SARIG's fractional CFO services include financial modeling and budgeting, monthly close and KPI reporting, cash flow management, fundraising support and data-room preparation, IIA compliance and grant reporting, ERP implementation (Priority), board presentation preparation, and strategic financial advisory.
A bookkeeper records transactions and an accountant ensures compliance, but neither provides strategic financial leadership. A fractional CFO sits at the executive table — building financial models, advising on fundraising strategy, managing investor relations, and making strategic decisions about cash allocation, pricing, and growth planning.
Yes. Pre-revenue startups often have the greatest need for financial structure — building investor-ready models, managing burn rate, preparing for fundraising rounds, and establishing financial controls before scaling. SARIG has experience supporting companies from seed stage through Series A and beyond.
SARIG specializes in HealthTech, SaaS, biotech, and medical device companies, with particular expertise in companies operating between Israel and the United States. The dual US-Israel CPA credential enables seamless support for cross-border financial operations, US GAAP compliance, and international subsidiary management.
