Web Development for Fintech Companies
We build the sites and portals a fintech company actually lives on.
Book a Discovery CallA public site that reads as trustworthy to a consumer or a bank partner in the first ten seconds, a KYC onboarding flow that gets an account funded instead of abandoned mid form,
And a trust center that holds up when an enterprise buyer or a bank compliance team goes looking for proof, not promises.
Your Website Is the First Compliance Document Anyone Reads
A fintech company sells trust before it sells a feature, and the website is where that trust is tested first. A prospective user decides in seconds whether an app that touches their money looks legitimate.
A bank partnership team, a payments processor, or an enterprise procurement lead reads the security page and the terms of service before they read anything about your product roadmap. An app store reviewer checks that your privacy policy matches what the app actually collects.
None of these audiences behave like a typical software buyer, and a generic marketing site built for a SaaS tool does not answer what they are actually checking for. If your site cannot show a clear licensing or partner bank disclosure, a real security posture, and an onboarding flow that does not fall apart on a real identity check, you lose the deal before a human ever emails you back.
The site is not a brochure sitting in front of the product. For a fintech company it is the first regulatory and security surface anyone examines, and it is judged accordingly.
A Site That Reads Like a Side Project Costs You the Partnership
When a bank partner’s due diligence team lands on your site and cannot find a licensing page, a partner bank disclosure, or any mention of a SOC 2 report, the conversation stalls before it starts. When a user starts the KYC flow, hits a form that was never built to handle a document upload or an address that does not match a template, and abandons halfway through, that is a funded account you never open.
When a funding round closes and the press wants a leadership page and a press kit within the week, a site built on a static template with no CMS structure turns a one day update into a two week scramble. Generic web agencies build fintech companies a clean homepage and stop there.
They do not know the difference between a money transmitter license and a bank partnership model, why a waitlist page needs different consent language than a live onboarding flow, or that a vague claim about returns or rates can create real regulatory exposure. The result is a site that looks fine to a design reviewer and fails every real test a bank, a regulator, or a serious user actually applies.
What Fintech Web Development Actually Involves
A site and portal built around how a fintech company is actually evaluated, by users, by bank partners, and by anyone doing diligence before a deal or a deposit.
KYC, Onboarding, and Waitlist Funnels
We build the onboarding flow that carries a user from signup through identity verification and account funding,
Plus a waitlist and early access funnel for products still gating access, with consent language and form logic matched to what each stage actually needs.
Security and Trust Center Pages
We build a dedicated trust center that shows your SOC 2 and PCI DSS status accurately, a security.txt file and vulnerability disclosure path,
And an NDA gated request flow for full audit reports, so an enterprise buyer or bank partner finds proof instead of a vague claim.
API and Developer Documentation Portals
For fintechs that expose their own APIs to partners or merchants, we build the documentation portal, sandbox access request flow,
And status page that a partner’s engineering team actually needs before they will integrate against your rails.
Core Banking, Payment, and KYC Integrations
We connect the site and portal to the rails your product actually runs on, whether that is Plaid for account linking, Stripe or Marqeta for card issuing,
Galileo, Unit, Increase, or Treasury Prime for ledger and banking as a service, and Persona, Alloy, or Sardine for identity and fraud checks.
Compliance and Licensing Disclosure Pages
We build the state licensing page with your NMLS ID kept current, partner bank or issuing bank disclosure footers on every page that needs one,
Versioned terms and privacy pages, and marketing copy structured to stay inside the no guaranteed returns guardrail your counsel sets.
Investor, Press, and Careers Site
We build the funding announcement and press kit templates, leadership bio blocks your own team can update without a developer,
And a careers page synced to your applicant tracking system, so a raise or a launch does not stall waiting on a web update.
What This Does for a Fintech Company
When the trust center, the licensing page, and the security posture are easy to find, a bank partner’s diligence team moves faster and a deal that used to stall in legal review closes weeks sooner. When the onboarding flow is built to handle a real identity check without breaking, fewer users abandon between signup and a funded account, and your support team stops fielding the same stuck upload complaint every day.
When funding announcements, press kits, and open roles can go live the day a round closes instead of two weeks later, the site stops being the bottleneck in your biggest growth moments. The site becomes proof, not decoration, and proof is what a fintech buyer, partner, and regulator are actually looking for.
Why a fintech’s website carries more weight than a typical company site
A fintech company’s site does double duty that a typical SaaS site never has to. It markets to users and business partners, and at the same time it is the first compliance surface a bank, a regulator, or an app store reviewer actually examines. A scrappy site with no licensing page, no partner bank disclosure, and no visible security posture raises a flag in due diligence long before anyone questions the product itself, because the absence itself reads as a gap.
That means the ordering of the page matters as much as the design. A corporate treasury team or a bank partnership contact reads the trust and legal pages before the feature pages, and if that proof is missing or buried three clicks deep in a footer, they assume the company is not ready for the relationship, whether or not that is true. We build fintech sites with that reading order in mind, so the pages a serious evaluator checks first are the ones easiest to find.
- ✓Security and trust pages read before feature pages by enterprise and bank partners
- ✓Compliance disclosures expected up front, not buried in a footer link
- ✓Fundraising and press timelines that outrun a typical website rebuild schedule
- ✓App store and bank partner reviewers who audit the public site directly
Compliance and licensing pages that hold up to scrutiny
Every fintech operates under some regulatory relationship, whether that is a state money transmitter license, a bank partnership model, or a registered broker dealer relationship, and the site needs to reflect the actual one, not a generic disclaimer. We build the state licensing page with your NMLS ID kept current, a partner bank or issuing bank disclosure such as banking services provided by a named bank, member FDIC, placed on every page that needs it rather than only the about page, and versioned terms of service and privacy pages so there is an audit trail of what a user agreed to and when.
We are not your compliance counsel and we do not draft the legal language your regulatory relationship requires. What we build is the structure and placement your counsel’s language lives in, plus a review pass on marketing copy so a headline about returns, rates, or outcomes does not drift into a guarantee your counsel would flag.
- ✓NMLS ID and state licensing page kept current
- ✓Partner bank or issuing bank disclosure on every relevant page footer
- ✓Versioned terms and privacy pages with an audit trail
- ✓Marketing copy reviewed against a no guaranteed returns guardrail
The integrations a fintech site and portal actually need
The public site is only half the build. The onboarding portal has to connect to the rails your product runs on: account linking through Plaid, card issuing through Stripe or Marqeta, ledger and banking as a service through Galileo, Unit, Increase, or Treasury Prime, identity verification through Persona, Alloy, or Onfido, and fraud signals through providers like Sardine or Sift. A waitlist form and a live KYC flow are not the same form with different labels, because the waitlist collects an email and an interest, while the live flow collects identity documents and has to hold up under an actual verification check.
A generic web agency treats these as one signup form and finds out later that a real user’s document upload, address mismatch, or duplicate account attempt breaks the flow. We build the intake and integration around what each provider actually returns, including a sandbox environment so your partners and prospective bank contacts can evaluate the flow before it goes live.
- ✓Account linking through Plaid
- ✓Identity verification through Persona, Alloy, or Onfido
- ✓Card issuing and ledger rails through Marqeta, Galileo, Unit, or Increase
- ✓A sandbox environment for partner and bank evaluation before launch
Turning security posture into a sales asset
For an enterprise buyer or a bank partner, security is the first question they ask, ahead of pricing or roadmap. We build a dedicated trust center that shows your SOC 2 Type II status, your PCI DSS scope if you handle card data directly, a security.txt file and a vulnerability disclosure path, and a request flow so a serious evaluator can ask for the full audit report under an NDA instead of taking your word for it. Many fintechs run this trust center through a platform like Vanta or Drata, and we build the public facing page to surface what that platform tracks in a way a non technical evaluator can still read.
We do not fabricate a security posture. If a certification is in progress rather than complete, the page says so plainly, because a bank partner’s diligence team checks these claims against the actual report, and an inflated claim costs more credibility than an honest in progress status ever would.
- ✓SOC 2 Type II and PCI DSS status shown accurately, not inflated
- ✓A security.txt file and vulnerability disclosure page
- ✓An NDA gated request flow for full audit reports
- ✓Subprocessor list and uptime history kept visible and current
Investor, press, and hiring pages on a fundraising clock
Fintechs raise in rounds, and every round comes with a compressed timeline: a funding announcement, updated leadership bios, a press kit, and a burst of open engineering roles, all expected to be live within days of a close, often coordinated around a press embargo. A site built on static pages that only a developer can edit turns that week into a bottleneck, right when the company most needs to move fast in public.
We build the CMS structure so your own team or PR agency can publish a funding announcement, swap in a new leadership bio, or update a press kit asset without waiting on a developer, and we sync the careers page to an applicant tracking system like Greenhouse or Lever so a hiring push after a raise shows up automatically instead of getting typed in by hand.
- ✓Funding announcement and press kit page templates
- ✓Leadership bios your own team can update without a developer
- ✓Careers page synced to Greenhouse or Lever listings
- ✓Fast turn publishing built for the week a round closes
Why Fintech Companies Choose Media @ Marsons
We are a full service growth and infrastructure partner, so your public site, your trust center, and the onboarding portal your users actually touch are built by one team that understands both the technical build and how a fintech company is evaluated. As James Whitfield, Managing Director at Media @ Marsons, puts it: a fintech’s website is doing the job a bank branch used to do, proving you are safe to hand money to before anyone reads a feature list.
We build with that in mind, from the licensing page to the KYC flow to the security center, so your site earns the trust it is being judged on.
Built around real diligence, not a template
We build the trust center, licensing page, and onboarding flow around what a bank partner, an enterprise buyer, or a regulator actually checks, so the site holds up under real scrutiny instead of looking good only at a glance.
Integrated with the rails you run on
We connect account linking, card issuing, ledger, and identity verification to providers like Plaid, Stripe, Marqeta, Galileo, Unit, Persona, and Alloy, so submissions and checks flow into the systems your product already depends on.
Compliance structure, not compliance advice
We build the licensing, disclosure, and terms pages to the structure your counsel sets, keep marketing copy inside the no guaranteed returns guardrail, and never claim a certification or audit status your company has not actually completed.
Owned end to end, on your timeline
From the public site to the onboarding portal to hosting and ongoing updates, we run the whole build, so a funding round, a new state license, or a product launch does not wait on three different vendors to coordinate.
What our clients say
216 pages live on one visual system, four content types each with its own template. We can publish at scale without the site turning into a pile that gets harder to search every month.
Four segments, each with its own route and copy, on one brand and one hiring process. 167 pages that still sort buyers at the first click.
An open-ended service business became two priced tiers on the page. Publishing the price filters the enquiries before they reach a human, which is worth more than the few it loses.
