Reven AI // about_reven
AI-managed accounting & sales tax compliance
Reven AI automates month-end close, multi-state sales tax filings, and reconciliation across 100+ tools — so finance teams can stop drowning in jurisdictions, spreadsheets, and late-filing penalties.

// why_we_exist
Built for the gap the Fortune 500 tools ignore
Since the 2018 South Dakota v. Wayfair ruling, any e-commerce or SaaS company selling across state lines has been on the hook for sales tax in 12,000+ overlapping US jurisdictions. The penalty for missing a filing is up to 25% of the tax owed.
The tools built for this problem were built for the Fortune 500. A 30-person D2C brand or a Series B SaaS team can't afford a six-figure seat plus a bookkeeper plus a Big-4 audit retainer — and they shouldn't have to. Yet they still spend 40+ hours every month stitching Shopify, Stripe, QuickBooks, and a payroll tool together by hand to close the books.
Reven AI was built for that gap. One AI agent reads your stack end-to-end, books the entries, monitors nexus across every state, and files the returns — so a finance team of two can run the books of a company of two hundred.
// what_we_believe
Principles we build on
Finance teams shouldn't grow linearly with revenue
The right software flattens that curve.
Accounting and sales tax belong on one platform
Splitting them across two vendors is how filings go wrong and reconciliations break.
Compliance is not a competitive moat
Filing on time should be a given, not a project.
AI should ship work, not summaries
Reven AI posts journal entries and files returns — it doesn't generate to-do lists.
Boring is the goal
A perfect close is one you forgot was happening.

Who's behind Reven AI
Previously founded Kintsugi, the sales-tax automation startup backed by Vertex. Kintsugi grew fast, but Barkın came away convinced that accounting and sales tax don't belong on separate platforms — every disconnect between them is where filings break, audits start, and finance teams lose nights. Reven AI is the platform he wished Kintsugi could have been: one AI agent that owns the books and the filings, end to end.
Barkın studied Entrepreneurship & Innovation at MIT (2021–2023) and earlier at Yale, where he was a varsity swimmer and Turkish National Champion. Based in San Francisco.
