Talk to the founderPricing & Scope
How much does custom web design cost for a St. Louis business?
Project investments are based on total page count, interactive feature complexity, custom API integrations, and content scope. Every project is scoped with a transparent, fixed-price milestone agreement. Focused corporate websites are delivered with full Figma UI/UX, custom Next.js engineering, and 100% code ownership with zero surprise overages.
Are there hidden monthly maintenance fees or recurring agency retainers?
No. We believe you should own your website outright. You contract directly with your preferred hosting provider (Cloudflare, Vercel) and pay zero monthly agency licensing fees.
How do you guarantee that project budgets remain fixed without overages?
We complete an exhaustive scope definition and architectural plan before writing a single line of code. All design components, page templates, and integrations are documented in a binding scope of work that guarantees delivery at the agreed investment level.
Why do St. Louis enterprise businesses and bioscience platforms choose custom Next.js over WordPress templates?
Next.js 15 delivers static generation and server-side rendering on global edge networks, eliminating database bottlenecks, vulnerable PHP plugins, and slow load times. This results in sub-500ms first contentful paint, automated SEO indexing, and enterprise-grade security with zero ongoing plugin maintenance headaches.
How do you design clinical and pipeline visualizer web applications for Cortex and 39 North plant science leaders?
We engineer clinical-grade digital flagships with interactive plant science and biotechnology pipeline visualizers, gated investor data rooms, and FDA compliance documentation search to convey scientific authority to research partners and global agtech investors.
How do you guarantee sub-500ms page load speeds and 100/100 Core Web Vitals across Missouri?
We optimize every asset from the foundation up: automatic WebP/AVIF image transcoding, critical CSS inlining, font subsetting, zero render-blocking scripts, and static HTML pre-generation delivered from global edge servers across the Midwest.
How do you structure custom Figma UI/UX design systems for corporate brands in Clayton and St. Louis?
We build complete Figma design token libraries with semantic color palettes, accessible typography hierarchies, auto-layout responsive components, and interactive micro-animations. This creates visual consistency across all digital touchpoints and enables rapid feature deployment.
How do you implement Schema.org JSON-LD structured data for Google AI Overviews and rich search results?
We embed granular Schema.org JSON-LD structured data on every page, including ProfessionalService, WebPage, FAQPage, BreadcrumbList, and Person schemas. These explicit semantic annotations enable search engines and LLM agents to accurately understand and cite your services.
What ADA accessibility standards and WCAG 2.1 AA compliance protocols do you build into St. Louis websites?
We engineer fully accessible web applications meeting WCAG 2.1 AA criteria: keyboard-navigable interface components, semantic HTML5 landmarks, ARIA labels, high-contrast color pairings, and screen-reader optimized content hierarchies.
How do you handle frictionless CRM and automated lead routing for commercial service firms in Clayton and Downtown St. Louis?
We build secure, webhook-driven form gateways that immediately route consultation requests, RFQs, and client intake data into Salesforce, HubSpot, or custom databases with instant email/SMS notifications and zero spam submissions.
Timeline & Process
How can you deliver a custom Next.js website in just 7 days?
We eliminate bloated agency bureaucracy and junior account layers. Our senior full-stack engineers and Figma UI/UX designers work directly with you through focused, daily milestone sprints to design, build, and deploy your site in parallel.
What is required from our internal team during the 7-day sprint?
We require brand assets (logos, brand guidelines), key service copy, and prompt feedback on the Figma design prototypes during scheduled milestone check-ins to ensure rapid project delivery.
What happens if we need design revisions during the process?
Every project includes dedicated design revision cycles during the Figma prototype phase, ensuring you approve every layout, color choice, and typography detail before development begins.
Next.js Tech Stack
Why choose Next.js 15 over WordPress or Webflow?
Next.js 15 delivers unbeatable performance with sub-second page loads, superior SEO through server-side rendering, rock-solid security without vulnerable plugins, and infinite scalability that monolithic page builders cannot match.
Can our marketing team edit text and images without touching code?
Yes. We integrate intuitive headless CMS platforms like Sanity or Strapi, allowing your marketing team to create blog posts, update service copy, and upload images through an easy visual dashboard.
How do you ensure our website achieves 95+ Core Web Vitals scores?
We optimize every asset using modern WebP/AVIF image formats, eliminate render-blocking JavaScript, implement static page pre-rendering, and deploy on Cloudflare global edge networks.
How do you handle SEO migration to prevent traffic loss?
We build comprehensive 1-to-1 301 redirect maps for every legacy URL, preserve existing URL slugs, implement structured JSON-LD schemas, and validate all meta tags prior to DNS cutover.
