Quillon builds AI for technical accounting and audit, where every answer links back to the exact source paragraph in the standards. It came to Creative Corner Studio the best possible way: a founder saw another client's website and asked for an introduction. Quillon paid the first invoice before the contract was signed, rebranded from its original name partway through the build, and had a client-QA'd site on staging three weeks after kickoff. The company has since returned twice, first for blog development and then for a venture pitch deck.

Quillon answers technical accounting and audit questions with AI, and its whole product promise is that you can check the work. Every claim links to the exact source paragraph, whether that is the ASC codification, an IFRS standard or an SEC filing. In the founder's own words: no hallucinated citations, no framework mixing.

A product built on verifiability needs a website that behaves the same way. Overclaim on the homepage and you undercut the one thing the product is selling.

How the work arrived

By referral, from a website. A team member at Juma, another Creative Corner Studio client, introduced the founder because he had been impressed by Juma's site. That is the shortest sales cycle we get: the work does the pitching.

The trust showed up early in a concrete way. The first payment arrived before the contract was signed.

Design and development

Kickoff was in March 2026. We built the art direction and a design system across desktop and mobile, wrote the copy jointly with the client rather than waiting to be handed finished text, and developed the homepage with its animations, navigation and a CMS template page. Site assets including favicon, web clip and Open Graph images were produced as part of the same pass.

The company rebranded during the build. That is the kind of mid-project change that derails a fixed scope, and it was absorbed without moving the delivery.

Three weeks after kickoff the site was on staging, the client had run QA through Feedbucket, same-day fixes were in, and the Webflow workspace had been transferred to their own account.

The relationship since

Quillon came back in May 2026 for blog development, and again in August 2026 for a venture pitch deck. Along the way the founder referred another prospect to us. Three engagements and an onward referral, from a site that started as a homepage.
