get started.
Find detailed scope and pricing on our service pages, or email the studio.
What does Third Coast Assembly do?
Third Coast Assembly provides website design and development for small businesses, plus apps, web tools, and focused software. We combine human strategy, design, and code review with AI-assisted development.
Is monthly website care required?
Yes. Our Starter and Custom website packages require ongoing care from launch, starting at $99 per month for Core or $199 per month for optional Growth care. Full scope and pricing are on the pricing page and confirmed in your proposal.
How do you use AI, and what does a human review?
AI helps with development behind the scenes. Human judgment guides the strategy and design, and a human reviews the layout, interactions, copy, and production code before launch.
How do I start a project?
Send the project brief with your idea, goals, budget, and timing. We will reply within two business days with a next step. Sending a brief does not reserve a project or create a client relationship; we confirm the scope, price, and terms in a separate proposal or agreement.
