No companies in this curated directory match those filters. That does not mean no suitable company exists in the market.
Where the approved sources support it, this list includes mobile banking, card issuance, investment-system modernization, and regulatory monitoring. Adjacent marketing claims are not treated as filterable expertise.
Building a product is not the same as taking on the buyer’s regulatory obligations. Ask who owns delivery, which integrations and reconciliation work are in scope, and how security and data access are bounded.
Hourly ranges and minimum project values are not in the current public sources for this cohort. Request current terms from each company. Do not infer a budget from headquarters or company size.
100Signals publishes this list as a buyer research resource. It is not itself a software vendor in these categories. Companies come from the 100Signals agency dataset and are included only when a public company source names a relevant project, client, or delivery portfolio. An industry label alone is not enough.
Order is alphabetical and is not a score. Inclusion is unpaid. 100Signals sells marketing services to software agencies and may have commercial relationships that are separate from this list.
Project pages and portfolio indexes are different. A portfolio index can support a narrower statement; it is not independently verified delivery. Source capture dates record when the source was stored, not when the work happened. Editorial review dates are shown per company when they exist; a missing date stays missing. Vendor outcome claims are not repeated as measured results.
Hourly rates and minimum project values are not in the current public sources for this cohort. Ask each company for a current proposal.
If a listed company needs a factual correction, email peter@100signals.com. Approved changes go through the company registry and a new release; review dates are not refreshed just because a URL still responds.
This is optional. You can use the comparison without sending anything. Peter Korpak at 100Signals receives the request. Names are not sent to listed vendors automatically.
