The complaint 'we use this for the company — the rates could be more beneficial and discounted' points to something real and underserved: mid-market companies know they're paying retail FX rates but have no mechanism to negotiate wholesale ones. Large enterprises have treasury teams that negotiate directly with banks. Sub-50-employee companies don't have enough volume to matter. The companies stuck in between — $10M-$200M revenue, $500K-$5M in annual international payments — have enough volume to qualify for better rates but no one on staff who knows how to negotiate them or which providers to approach.

This gap persists because the advice is genuinely complex: the right currency provider depends on which currencies you use most, whether your flows are predictable or lumpy, whether you need hedging, and whether your ERP can connect via API. A generic broker has an incentive to push you toward whoever pays the highest referral fee, not whoever is cheapest for your specific pattern. There's no independent, ongoing advocate for the buyer.

What's broken for users right now: they're paying 1-2% FX spreads on every international transaction inside their expense tool, they've been told 'this is the rate,' and they have no benchmark to know if that's bad. The complaint 'exchange rates are high on dollar compared to others' is someone who suspects they're being overcharged but has no data to act on it. They can't negotiate what they can't measure.

This is a business because a company's FX cost structure doesn't get solved once — it needs to be revisited as transaction volume grows, as new currency corridors open up, and as providers change their fee structures. A company that saves 0.8% on $2M in annual FX flow saves $16,000/year. An ongoing advisory relationship that monitors their actual rates, benchmarks them quarterly against current market rates, and triggers a renegotiation conversation when the gap exceeds a threshold is worth a recurring fee — and the savings are large enough relative to the fee that the value is easy to demonstrate.

What to build

Build a subscription service for mid-market finance teams that ingests their international transaction history, calculates their effective FX spread per currency corridor, benchmarks it against current interbank and wholesale rates, and provides a quarterly report with a prioritized list of corridors worth renegotiating — including specific rate targets to bring into negotiation with their current provider.

Where to start

Start with a one-time free FX audit for finance teams who export 90 days of transaction history — the audit delivers immediate, concrete value (here is exactly how much you overpaid) and creates a natural reason to sell the ongoing monitoring subscription.

The hard part

Getting companies to share transaction-level payment data with a third party requires significant trust-building and sometimes legal review — the sales cycle will be longer than expected, and early customers will want a manual, consultative engagement before they'll connect any API or upload any file.

How it makes money

Annual subscription fee based on total international payment volume analyzed, starting at a flat rate for companies under $1M in annual FX flow and scaling by tier — optionally augmented by a one-time setup fee for the initial audit and provider renegotiation support.
