Island Waters Accounting LLC

Island Waters Accounting LLC

Island Waters Accounting is an AI-first fractional CFO and Client Advisory Services firm based in Peoria, Arizona, serving growth-stage founders on monthly retainers. We turn financial complexity into clear, survivable decisions for the founders who need it most. We specialize in four industries: Healthcare and Biotech, Pharma, Pharmacy, and Technology (AI). These are capital-intensive, regulated, milestone- and runway-driven businesses led by brilliant technical founders who are often financially unsophisticated and understandably anxious about what the numbers reveal. We are equally happy to serve a strong-fit client in any industry where we can deliver real value. Founder and CEO Shawn Elliott brings 23-plus years of senior finance experience, including two private equity exits: scaling The Apothecary Shops and Avella Specialty Pharmacy from roughly $50M to $500M in about five years, and building Integrity Rx from $0 to roughly $50M in about 4.5 years. He also supported a pharmaceutical client's monthly close and accrual accounting as that company scaled toward a public offering. Our service tiers span the full company lifecycle: • Discover and Embark: squeaky-clean books, bank reconciliation, accrual accounting, and clear monthly reporting. • Launch, Scale, and Exit: CFO-level partnership including forecasting, 13-week cash flow, KPI dashboards, board- and investor-ready reporting, and transaction support through a raise, a lender relationship, or a sale. Clients graduate up as they grow, so the relationship deepens rather than resets. What sets us apart: AI-amplified senior judgment at a fraction of the cost of a full-time CFO or VP of Finance (commonly $250K to $450K or more all-in), genuine depth in regulated verticals, and full lifecycle coverage including the exit phase most firms under-serve. The machine drafts, the Principal signs, and nothing reaches a client without human review. We work in Brex, QuickBooks Online, Maxio, Tabs, and Xero, and connect natively to client systems. Our values are simple: calm in the storm, character when no one's watching, and we advise, you decide. It is your business and your call. We are here to help you do what you do best, which is grow your business. Learn more at islandwaters.ai.

Median

Median

Median (MedianFi.com) is the finance team for owner-led businesses and US startups. Most owners get their books back weeks after the month they describe, once the decisions have already been made. Median works the other way around. Your bank, card, payroll and billing feeds map into a general ledger, AI categorizes and posts transactions every business day, and an accountant who knows your business reviews the exceptions. Your books stay current, so when you need a number you get it the same day you ask. Clean books are the foundation of the work, not the finished product. The questions owners actually ask are which clients, products and people are profitable against what they cost, how much more can go out this month before margin drops below target, where the money went and what changed, and how much runway is really left. We build the reporting and analysis that answer those questions on top of your live numbers, and keep them in front of you every month, so nobody is rebuilding a model in a spreadsheet the night before a board meeting or a bank call. We hire accountants and we build our own software. The software carries the volume that used to be a full week of somebody's data entry, and the accountant on your account carries the judgment, catches what the automation gets wrong, and is one message away in Slack, email or text. You always know the name of the person doing your books. We work in QuickBooks Online or Xero, or we can move you onto the platform we built, which runs the ledger and gives you a dashboard of the metrics and reports we build for your business. Migration is free and the price is the same either way. Pricing is metered on your actual financial accounts and transaction volume, so the bill tracks the work your books take rather than a headcount or a tier you have outgrown. Engagements are month to month with no term commitment. Our clients are startups and owner-led businesses: SaaS and AI companies, agencies, consultancies and studios, e-commerce, and professional services firms, including US entities whose founders live outside the country. We keep the books and coordinate the return with the preparer who signs it, so the filing is built from books that are already current rather than reconstructed at year end. By Median Labs Inc.
