Why ThirteenBytes

The way an agency should work

Four commitments we make on every engagement — put them in the contract if you like.

Senior hands only

No juniors learning on your budget. The people who quote your project are the people who build it.

Fixed quotes, kept

A written scope and a fixed price before we start. Surprises belong in products, not invoices.

Demos every week

A working link you can open every Friday. No black box, no big reveal, no “trust us”.

Care after launch

Launch is the start. Monitoring, updates, and a real person who answers when something needs attention.

What we build

Nine services. One accountable team.

Design, build, launch, rank, and run — without juggling five different vendors.

Web development

Marketing sites, web apps, and platforms built for speed, accessibility, and conversion.

Mobile apps

iOS and Android apps designed, built, and shipped to the stores — with the backend to match.

Learn more →

E-commerce

Storefronts on Shopify, WooCommerce, or fully custom — tuned for checkout and repeat buyers.

Learn more →

UI/UX design

Research, wireframes, prototypes, and design systems that make products feel obvious to use.

Learn more →

SEO & growth

Technical SEO, content, and analytics that move you up the rankings — and keep you there.

Learn more →

Custom software

Dashboards, portals, integrations, and internal tools shaped to the way your business runs.

Learn more →

Cloud & DevOps

Hosting architecture, CI/CD pipelines, and monitoring — so releases are boring and uptime is not news.

Learn more →

AI & automation

Practical AI: chat assistants, content pipelines, and workflow automation that saves real hours.

Learn more →

Maintenance & support

Updates, monitoring, and rescue work — for products we built and ones we inherit.

The deliverable

Not just a website. A working system.

Every build ships as a complete, operating asset: fast pages, mobile-ready layouts, analytics wired in, search engines notified, forms delivering to your inbox, and documentation for whoever touches it next. You get the keys to all of it — code, accounts, and dashboards.

  • Performance budgets — pages that score 90+ on Core Web Vitals
  • SEO foundations on every page, sitemap and schema included
  • Analytics and conversion tracking from day one
  • Accessibility and mobile checks before every release
How we work

Five steps, in order

The same process on every project — because it works, and because you always know where things stand.

STEP 1

Discover

A working session on the problem, the users, and what “done” means. You get a plan and a fixed quote.

STEP 2

Design

Screens you can react to before code is written. We revise until it says exactly what your business does.

STEP 3

Build

Short cycles, working software weekly, and a demo link that is never more than a few days old.

STEP 4

Launch

Store submissions, domains, analytics, SEO checks — the unglamorous details that make launches smooth.

STEP 5

Grow

Rankings, speed, conversion, new features. The compounding work that turns a launch into a business.

Questions

Asked often, answered honestly

How much does a typical project cost?
It depends on scope, which is why every engagement starts with a free discovery call and ends its first week with a written, fixed quote. Marketing sites, storefronts, and MVPs each have very different footprints — we will tell you the smallest version worth building and what it costs before you commit to anything.
How long does a website or app take?
A focused marketing site typically ships in 2–4 weeks; e-commerce builds and MVPs usually land in 4–10 weeks depending on scope. You see a working demo link every week from week one, so progress is never a mystery.
We are in the US. How does working across time zones work?
We are remote-first and deliberately overlap with US business hours. You get responses during your working day, weekly demos scheduled in your time zone, and a single point of contact — not a ticket queue.
Who owns the code and accounts?
You do. Code lives in a repository you own, domains and hosting sit in your accounts, and we document everything. If we ever part ways, you lose nothing.
Can you take over an existing project another team built?
Yes — rescue work is a specialty, not a favour. We audit the codebase, tell you honestly what state it is in, stabilise the urgent parts, and then improve it incrementally instead of demanding a rewrite.
