Co-sourced AI Controllership
Great books drive great decisions
We embed with your finance team and put AI to work on your books - closed, reconciled, reported, and planned forward. We start with your close; AI drafts, a human controller signs off, and when the work needs a platform, we run it on RoboLedger and the RoboSystems platform beneath it - open source, and yours to own.
Not ready for a call? and we’ll come back within one business day.

We sell outcomes, not hours
We meet you where you are - start with high-leverage AI wins on the stack you already run, and graduate to the full graph-native platform when the value justifies it.
AI opportunity assessment
We map your close and finance workflows, find where AI safely fits (and where it doesn’t), and hand you a prioritized plan. Platform optional.
Close & controllership
A reliable, on-time close - drafted by AI from your policies, reviewed and posted by a human controller. Every transaction lands in an inbox pre-classified, with the exact entries shown before anything posts, so approval is a real decision rather than a rubber stamp. Audit-ready statements, every period.
Data integration & engineering
We build custom adapters - QuickBooks today, plus bank feeds, ERP, billing, CRM, and custom APIs - into one knowledge graph, with custom schemas that model any domain, not just accounting. New sources land as engagements, not multi-quarter migrations.
Reporting, analytics & planning
GAAP-grade, XBRL-native statements, board and LP packs, and benchmarking against public-company data. Then forward: monthly statements and your scenario’s assumptions in one grid, so the forecast is driven by the ledger you just closed - not a spreadsheet copied out of it.
Custom reporting frameworks
Report under your own framework - a regulatory regime, an industry standard, or your firm’s methodology. We author the taxonomy, wire it to render natively, and maintain it as the rules change. Your framework, your tenant, kept current.
AI & workflow automation
AI that drafts entries, answers questions in plain language, and reconciles against your source systems - and searches across your policies, contracts, and filings with full context.
Custom build & deployment
Bespoke reporting flows, custom data adapters, and AI tooling - on RoboSystems or your existing stack. Built to run in your AWS account, on your terms - we work through the public API with a key you issue and can revoke.
Enablement & support
Onboarding, training, and a support line - so your controllers and client-facing teams run the platform with confidence. Built for firms white-labeling across their book.
Managed operations
We keep it running: monthly delivery, upgrades, monitoring, and a human controller on retainer - so the work just shows up, done.
How engagements work
A live demo comes first and costs nothing. The ladder starts once we both think it’s a fit.
Teardown
A fixed-fee diagnostic of your current close
Pilot
One real close, run end to end, so you see the outcome
Managed
Ongoing close & reporting on an outcome-based retainer
Build
Custom adapters, reporting frameworks, and deployment
Pricing is transparent and aligned to the outcome - never billable hours.
Open, auditable, and yours
Most AI-accounting firms sell a black box and promise autonomy they can’t deliver. We do the opposite - because when it’s your books, trust is the product.
See the platform on GitHub01No black box
The platform is open source. Read the code. See exactly how every number is produced, with provenance back to the policy behind it.
02No lock-in
Open formats and a forkable platform. Take it in-house and self-host whenever you like. You will never be stranded by a vendor shutting down.
03No overpromise
AI generates, humans approve. We sell a reviewed, signed-off close - not an autonomous accountant that quietly breaks on the hard cases.
04Your infra or ours
Run fully managed on our service, or in your own AWS account. Same open platform either way. When it is yours, we stay out of it - support and integration work happen through the public API, with a key you issue and revoke.
05Advice first, software second
If targeted tooling solves it, we won’t sell you a platform. We’re accountants who deploy AI to fit the problem - and we’ll tell you what you don’t need.
A decade of driving innovation in financial data
Harbinger FinLab is led by Joseph T. French, an inactive CPA who’s spent his career at the forefront of financial data. At Workiva, he was a principal engineer building innovative financial systems - and an entrepreneur who’s founded multiple companies and served on boards.
So this isn’t a chatbot bolted onto accounting. We build on RoboSystems - our own AI-native financial platform - and run our own books on it: an AI-drafted close, a human controller’s sign-off, GAAP-grade statements. It’s how we run our business, and how we’d run yours.
Proven beyond accounting
Supply FlowQC - an AI supply-chain resiliency product for healthcare - runs on the same RoboSystems platform that runs our books, proving it models any domain, not just accounting.
Let’s get your books driving decisions
Start with a live demo - a complete set of books, closed and reported, walked through end to end. If it’s a fit, taking apart your own close is the next step.
