Sanity & Next.js agency for fintech

Fintech marketing teams arrive with the same bottleneck in different shapes. The roadmap sits with marketing, the deploy pipeline sits with engineering, and every landing page has to cross between the two.

For LiveMore Mortgages we built a modular page builder in Sanity: drag-and-drop content blocks, SEO settings on each component, and Sanity image optimization with hotspot controls, so a campaign page gets assembled by the people writing it. Mortgage Rob sits at the other end of the scale, a sole broker who wanted to keep editing his own site, so the Sanity setup is shaped around one person and shows him how copy, FAQ answers and blog posts will land before anything publishes.

Airtime Rewards needed a marketing site that could carry a cashback platform past a million users. Tabby AI needed the component library underneath every surface they ship, built for right-to-left layouts and accessibility from the first commit rather than retrofitted after launch.

Sanity and Next.js on Vercel is the default pairing, and most fintech work here uses it: Sanity for structured content the marketing team owns, Next.js for rendering, Vercel for preview deployments on every change.

It is not the only answer. Airtime Rewards runs on Gatsby and Netlify, with lazy-loaded imagery and Netlify's caching and asset optimization doing most of the performance work. Mojo Mortgages already had a Gatsby foundation and content split across two separate headless systems, so we built on what was there instead of forcing a consolidation into a four-week window.

Where a fintech brand ships across several markets, the component library becomes the main deliverable. Tabby AI's library was documented and tested component by component in Storybook, so their designers and our engineers worked against the same reference and their internal team could keep extending it after handover.

These are numbers from the projects above rather than industry averages.

LiveMore's landing page creation went from weeks to hours, updates went live five times faster, and their marketing team launched 12 new campaign pages in the first month with no developer involved.

Airtime Rewards hit 0.4 seconds to First Contentful Paint and 0.6 seconds to interactive, with a perfect 100 across all four Google Lighthouse audits: performance, accessibility, best practices and SEO. The platform passed a million users after launch.

Mojo Mortgages had a fixed four-week window before their RVU acquisition announcement. Four mortgage landing pages launched on schedule, their Product Owner called them lightning fast, and the work was immediately extended to four more subpages on the same architecture.

Tabby AI's move from Sanity v2 to v3 was used to rebuild the schemas around reusable structures, so content is created once and surfaced across their site and their apps instead of being duplicated per surface.

Financial copy gets reviewed, and the review is usually the slow part. Structure is what makes it manageable. When a rate, a disclaimer or a product description is a field rather than text baked into a page, it changes in one place and every page carrying it updates with it.

Preview matters for the same reason. Reviewers sign off on what the page will actually look like, so every build here ships real preview before publish rather than a staging link that drifts from production.

Version history and traceability come with Sanity rather than being bolted on, so there is a record of who changed what and when. For teams operating across markets, internationalization and accessibility have to be part of the component library instead of a later pass, which is how we approached Tabby AI's build for the UAE.
