Website Design and App Development for St. Louis, Missouri

Startups coming out of Cortex and the university pipeline need working software fast, but hourly agency billing makes runway planning a guessing game.

Every Vaylo build is fixed price before work starts, with MVPs and SaaS products typically running $5,000 to $30,000. Staged delivery with review links means you can show traction to investors mid-build. No hourly meter, no scope drift surprises.

Agtech and B2B companies in the region sell sophisticated products through websites that explain none of that sophistication.

We build sites that translate technical depth into clear buyer-facing pages: product architecture, use cases, data, and proof, structured for people who make purchasing decisions. The engineering underneath is as strong as the copy on top. Your site finally does justice to what you actually sell.

Established family-owned businesses across metro St. Louis rely on reputation, but the next generation of customers finds vendors on their phones first.

A $1,500 to $5,000 marketing site rebuild puts decades of reputation into a format mobile-first customers trust immediately. Add Build My Pulse and inquiries get answered, followed up, and scheduled automatically. The reputation keeps working even when nobody is at the desk.

Do you build MVPs for St. Louis startups?

Yes. St. Louis has a real startup pipeline through Cortex, the universities, and the agtech cluster, and we build the software those companies need to launch: SaaS MVPs, web applications, and mobile apps on React Native. Fixed pricing between $5,000 and $30,000 for most builds keeps runway math predictable.

What does a website cost for a St. Louis small business?

Custom marketing sites run $1,500 to $5,000 depending on page count and functionality. That is a fully custom build on modern infrastructure, not a template. E-commerce starts at $5,000. You get the exact number in a proposal within 24 hours, and it does not move unless the scope does.

Can you handle technical or scientific products, like agtech?

That is a strength. The plant-science and agtech companies around St. Louis sell complex products, and their sites need to communicate that complexity to buyers, partners, and investors without drowning them. We structure content around how technical buyers evaluate, and we build the interactive and data-driven elements in-house.

How does working remotely with you actually feel?

Direct and fast. You talk to the people building your product, not an account manager. Every stage of the build ships with a review link, so you watch the real site or app come together and course-correct early. Calls and async updates happen on your schedule.

How would AI automation help a service business here?

Build My Pulse deploys an AI operator in two weeks that captures leads, follows up until they respond, books jobs onto your calendar, and reports daily. For contractors, clinics, and service firms across the metro, it removes the response-time gap that quietly loses the most business.
