Closegrove was started by a CPA who ran month-end close and a Stripe engineer who understood financial data pipelines. They built the tool neither could find when they needed it.
CEO & Co-Founder
CTO & Co-Founder
Head of Customer Success
The Closegrove team combines controller experience, financial infrastructure engineering, and enterprise customer success — all in the mid-market finance segment.
Jonathan Klein spent three years as a controller at a Series B SaaS company before co-founding Closegrove. A CPA, he has a firsthand understanding of the reconciliation bottlenecks that slow mid-market close cycles — he ran them every month. He leads product direction and customer relationships at Closegrove, and is the primary contact for controllers evaluating the platform.
Natalia Voss brings four years of infrastructure engineering experience at Stripe, where she worked on financial data pipelines and ledger systems at scale. Her background in building reliable, auditable financial systems underpins Closegrove's reconciliation engine. She graduated from MIT with a degree in Computer Science and leads all engineering decisions at the company.
Raymond Chu joined Closegrove from Brex, where he led enterprise onboarding for mid-market finance teams across hundreds of accounts. He understands the workflows, ERP environments, and organizational constraints that finance teams bring to new tooling. He leads customer success and implementation at Closegrove, ensuring finance teams see reconciliation time reduction in their first close cycle.
Jonathan and Natalia met through a YC alumni network event in 2022. After building and validating a prototype matching engine with a design partner — a 60-person SaaS company that cut their reconciliation backlog from 140 items to under 20 on the first run — they incorporated Closegrove and began working with mid-market finance teams on NetSuite and QuickBooks.
The three-person team intentionally keeps close contact with every customer's close process. Controllers and VPs Finance have direct access to the team — not a support queue — and the product roadmap reflects what customers report as the largest remaining source of close friction.
Closegrove is headquartered at 32 Old Slip in the Financial District of Manhattan, a few blocks from the firms and finance teams we serve. We welcome in-person conversations with controllers evaluating the platform.
