Your idea comes first
Before the details,
let’s talk confidentiality.
Have something you want to keep under wraps? We offer non-disclosure agreements (NDAs) before confidential project discussions.
Request an NDA first. We’ll review the terms together and sign an agreed version before you share sensitive details.
Request an NDASubmitting an inquiry requests an NDA; it does not create a signed agreement. Keep your first message high-level.
No mystery. Just momentum.
From “what if”
to what’s next.
You’re part of the process, not waiting on the sidelines. We’ll make the important decisions together.
Talk it through.
Your goals, your audience, your idea. Need an NDA? We’ll address that before the confidential details.
Make a plan.
Agree on the features, deliverables, timeline, and price before the work begins.
Build & refine.
Review the design and working previews. Share feedback as your project takes shape.
Make it real.
Test, launch, and walk through the handoff. Ongoing maintenance can be scoped separately.
INDEPENDENT BY DESIGN.

Good questions
A little clarity
before we start.
No need to have every detail figured out. A useful conversation is a good place to begin.
Ask me somethingHow much will my website or app cost?
Pricing depends on the scope: the pages or screens, features, integrations, and content involved. We’ll discuss what you need and put together a clear quote before work begins. Hosting, domain, and third-party service costs will be identified separately where they apply.
Can we sign an NDA before I share my idea?
Yes. Select “I’d like an NDA first” in the inquiry form. We’ll review and agree on the terms before signing. Please wait until both sides have signed an agreed NDA before sharing confidential details. The inquiry form itself is not an NDA.
What do you need from me to get started?
A high-level description of your business, who it serves, and what you’d like your website or app to do. Existing branding, content, and examples you like are helpful, but you don’t need a finished plan to start a conversation.
How long does a project take?
The timeline depends on the project’s size, technical requirements, content readiness, and review process. We’ll agree on a realistic schedule during scoping. App store review and other third-party approvals can affect launch timing.
What happens after launch?
We’ll walk through the agreed handoff and how to use what’s been built. Ownership, access, included support, and third-party licenses will be covered in the project agreement. Additional updates and ongoing maintenance can be quoted separately.
The next good idea starts here
Let’s make
your next thing.
Tell me a little about what you have in mind. We’ll start with a conversation, not a commitment.
A conversation with your actual builder A project scoped around your needs No confidential details needed to start
Prefer to start with an NDA?
Check the NDA option in the form. A brief introduction is enough until we have an agreement in place.
