Gillette's economy has always leaned on coal and energy, but the last few years have pushed local banks, credit unions, and small financial-service startups to think beyond the region for their technology needs. There isn't a dense pool of fintech developers inside the city limits, so businesses here are doing what companies in similarly sized markets across the US already do: hiring specialized, remote software teams instead of building one from scratch. Whether the need is a neobank app, a payment gateway integration, a peer-to-peer lending platform, or compliance-heavy wealth management software, the vendor search almost always ends up national or global.
That's not necessarily a bad thing. A remote fintech partner usually means a bigger, more specialized team than a local shop could staff, and most of these companies already work across US, UK, and Canadian time zones — so the distance rarely shows up as a communication problem in practice. It does mean the vetting process matters more, since you can't just walk into an office and see the team working. Below is a working list of eight companies that keep showing up when businesses run this kind of search, starting with the one we know best.
1. Dev Technosys — Featured Partner
A quick disclosure before anything else: Dev Technosys is who we work with, so it's listed first as our featured partner rather than as a claim to an objective #1 spot. With that out of the way — the Jaipur-based company has built a fairly deep bench in fintech app development, covering everything from neobanking and BNPL to stock trading platforms and crypto exchanges. Its case list includes UABPay, a Salesforce-integrated AI lending platform, the trading-focused eToro build, and a secure crypto exchange built for a startup client. On the compliance and security side, the team publishes its approach to real-time fraud monitoring, which matters more than most feature lists once real money starts moving through an app. The Hindu has named the company among the top fintech software developers serving the US market, and its Clutch reviews point to steady communication as much as technical output — worth checking directly rather than taking our word for it.
2. ScienceSoft
A Texas-headquartered, ISO-certified software development company with over three decades in business, ScienceSoft has quietly built one of the more mature fintech practices in the industry. It tends to attract banks and insurers rather than early-stage startups, largely because its engagement style is closer to enterprise consulting — long discovery phases, detailed documentation, formal QA cycles. Good fit if your Gillette-based business is a credit union or an established lender modernizing legacy systems rather than launching something new.
3. Appin
Appin has offices across India, the US, and the UK, and its fintech portfolio leans toward mobile-first products — digital wallets, lending apps, and a few neobank builds for clients in Australia and the Gulf. The company is fairly transparent about pricing ranges on its site, which is a small but useful thing when you're trying to budget a project before the first sales call.
4. Intellectsoft
Intellectsoft splits its work between blockchain-based fintech products and more conventional banking software, with a client list skewed toward mid-size US enterprises. Its blockchain angle makes it a reasonable option if the project involves tokenization or smart-contract logic rather than a standard app-and-backend build.
5. Infosolutions
Smaller than most names on this list, this company works mainly with early-stage fintech founders — the kind of client building a first version of a personal finance app or a lending MVP on a fixed budget. That size cuts both ways: rates tend to be lower, but so is the bandwidth for handling multiple concurrent workstreams.
6. Hidden Brains
Hidden Brains has a long track record in payment gateway integrations specifically — Stripe, Plaid, and regional processors — which makes it a practical shortlist candidate if the core problem is "we need to move money reliably" rather than a full fintech platform build. It's less known for original product design.
7. Andersen
Andersen runs distributed teams across Europe and the US and has done a fair amount of digital banking work for UK-based clients, including core banking modernization projects. It operates more like a staffing-plus-delivery model, which suits companies that want a dedicated team embedded long-term rather than a fixed-scope contract.
8. Itransition
Itransition's fintech work covers insurtech and wealth management builds more than most on this list, including portfolio-tracking dashboards and underwriting automation. The company has been around since the late 1990s, and its documentation and handoff processes reflect that — useful if you expect to bring the product in-house eventually.
What actually matters when you're comparing them
None of this is complicated, but it's easy to skip when you're comparing polished portfolio pages. Ask for live app links, not just case study screenshots — a shipped payment or lending app tells you more than a mockup. Ask how they handle PCI DSS or SOC 2 requirements specifically for your product type, since "we know compliance" means very different things for a neobank versus an insurtech tool. Ask what post-launch support actually costs, because fintech apps need ongoing patching in a way marketing sites rarely do. And talk to at least one past client directly if the vendor will connect you — reviews on Clutch or G2 are a starting point, not the final word.
For a Gillette business, the location of the vendor matters less than it used to. What matters is whether the team has actually built something like what you need, whether they can show it to you before you sign anything, and whether their answers on compliance and support hold up under a second round of questions — not just the first.
It's also worth sizing the vendor to the project rather than the other way around. A five-person shop building your first lending MVP on a tight budget is a very different fit than an enterprise consultancy modernizing a credit union's core banking system, even though both might call themselves "fintech software development companies." Get scope, timeline, and a rough cost range in writing before comparing anyone on this list against another — the shortlist above is a starting point for that conversation, not a substitute for it.
