About Doug Schiller
Fractional CFO, reconciliation expert, and the maker of MatchData.ai.
This is the professional home of Doug Schiller — a fractional CFO, reconciliation expert, and the founder of MatchData.ai. After a decade of doing month-end matching by hand, Doug built and patented software that automates complex reconciliation across banks, payment processors, and general ledgers (U.S. Patent 11,475,026).
This site is where Doug shares his work and his thinking. It serves founders and finance leaders at technology and fintech companies — from early-stage startups through high-growth businesses preparing for institutional investment. Here you'll find his fractional CFO services, covering accounting reviews, data strategy, financing, business planning, and AI integration, alongside a blog on reconciliation, the month-end close, and the tools he builds.
Everything here is written and maintained by Doug, a Columbia University MBA who has served as interim CFO at multiple technology companies. If clean financials and a defensible close matter to your business, you're in the right place.
