What we build

From a single portal to a full platform

Custom web software that fits your workflow exactly — not a template you have to bend around.

Custom web apps

Bespoke applications built around your exact workflow — fast, focused, and yours.

Customer & partner portals

Secure, self-serve portals that cut support load and make your customers feel taken care of.

Internal tools & admin

Replace the spreadsheet and the manual workarounds with tools your team actually wants to use.

Dashboards & analytics

Turn scattered data into clear screens that drive faster, better decisions.

Integrations & APIs

Connect the tools you already run on — CRMs, ERPs, payment and data systems — with clean APIs.

Roles & access control

Granular, role-based permissions and audit trails — security that holds up as you scale.

How it works

From workflow to working software

Fixed scope, weekly demos, and an architecture documented for whoever maintains it next.

01

Discovery & scope

We map the workflows and data, then lock a fixed scope and price.

Week 1
02

Architecture & design

A scalable data model and a clickable UI for the core flows, validated first.

Week 1–2
03

Build & integrate

Roles, dashboards and integrations — real software, demoed every week.

Week 2–7
04

Launch

Deploy to production with monitoring and docs, and hand over the keys.

Week 8
05

Scale & maintain

Add features and harden performance as usage grows — same team, no ramp-up.

Why Velcod

The senior team that actually ships

No juniors learning on your budget, no endless discovery, no surprise invoices.

Shipped in weeks

A working web app in weeks, because we scope tightly and build with proven tooling.

Fixed scope & price

You approve the scope and the number before we start. No hourly meters.

You own the code

Full IP and documented source handover at launch. No lock-in, ever.

Senior-only team

Product, design and engineering leads who've shipped dozens of apps work on yours.

AI-accelerated

We use AI across design and build to compress months of work into weeks.

Weekly demos

See working software every week. You're never left wondering what you're paying for.

Engagements

Choose the right size for your stage

The 6 ways web app builds go wrong — and how we prevent each

Most projects don't fail on the idea. They fail on these. Here's how we engineer them out.

01

Unclear requirements

Fixed scope up front. We map and sign off the workflows before building.
02

Budget overruns

One fixed price. Approved before kickoff. No hourly surprises, no creeping invoices.
03

Missed deadlines

Weekly demos. Visible progress every week keeps the launch date honest.
04

Brittle architecture

Built to scale. A clean data model and architecture that grows instead of buckling.
05

Integration hell

Senior engineers on APIs. We've wired the messy systems before — yours won't be the first.
06

Vendor lock-in

You own everything. Documented source and IP — never trapped with us or anyone else.
Why not the alternatives

Book a free call
What kinds of web apps do you build? +
Customer and partner portals, internal tools and admin panels, dashboards, CRMs, marketplaces, and complex data-heavy apps — anything custom that a template can't do well.
How long does it take? +
Most web apps launch in 4–8 weeks depending on complexity, which we lock in discovery so your launch date is real.
How much does it cost? +
A validation prototype starts at $4k; a production build is typically $12k+. You get one fixed price approved before we start — no hourly meters.
Will it scale as we grow? +
Yes — we choose a clean data model and architecture that grows with your users and data, and we document it so it stays maintainable.
Can you integrate with our existing systems? +
Yes. We connect CRMs, ERPs, payment, auth and data systems via clean APIs and webhooks — integration is one of the things we do most.
Do I own the code and IP? +
100%. You own all source, designs and IP, with documentation, handed over at launch. No lock-in.
What happens after launch? +
Take it from here, or keep the same senior team on a monthly Scale engagement to add features and harden performance as you grow.
