Trusted by funded founders raising seed → Series B

Senior Valocity engineers building a custom iOS and Android app together in the studio Concept → App Store, in 8 weeks
  • 12 wks To your MVP, in both stores
  • 100% Senior, in-house engineers
  • 0 Juniors on your pod
  • 1 Founder on every call

We build production-grade apps for founders who plan to custom web and mobile apps.

Most apps die in the gap between the demo and the millionth user. We build on the other side of that gap from day one. Senior engineers only. No juniors. The people who architect your app write it and ship it.

Production code from the first commit. Tested, scalable, App Store ready. The version we launch is the version that scales, so you'll never pay us twice to build the same thing. Start here.

Engagement Shapes

Three tiers. Anchor prices. Real ranges.

Every engagement is fixed-price by milestone and ships on the same AWS-grade infrastructure. Final scope is set in the Founder Call. These are the ranges real clients have invested over the past 12 months.

The Launchpad

Quote on Strategy Session

Prove the product fast.

MVP from zero in 8 weeks. Native iOS + Android, from discovery workshop to App Store submission. Best for solo founders and small teams looking to get one of their first projects out there with affordability.

The Enterprise

Quote on Strategy Session

Scale-ready from launch day.

For those who are ready to scale to the top of the charts, a senior team of its own, a security audit and threat model, full marketing package and a 12-month support retainer.

The Full Range

Some of our app development services

Six ways we build. Whatever you’re hiring us for, the same senior team scopes it, builds it, and ships it. No handoffs, because handoffs are where speed and quality die.

Book a Founder Call

Custom App Development

Native iOS and Android, built from scratch around your product and your users. Swift/SwiftUI and Kotlin/Compose, or Flutter when cross-platform serves your roadmap. Clean code built to scale, with rigorous QA and no technical debt quietly shipped on day one.

Deliverables: Production codebase, authentication, APIs, third-party integrations, App Store and Play Store submission.

Website-to-App Conversion

Turn the website that’s already working into a native app your customers carry in their pocket. We rebuild your web experience as a true iOS and Android app, push notifications, offline access, app store presence, without rebuilding the business logic you’ve already proven.

Deliverables: Native iOS and Android apps, push notification setup, offline functionality, full store submission and approval.

Custom Website Development

Fast, modern, conversion-built websites that look premium from the first scroll and load like they were engineered, because they were. Whether it’s a marketing site, a web app, or the foundation we’ll later turn into your mobile app.

Deliverables: Responsive website, CMS integration, performance optimisation, analytics, and full handover with IP.

Product Strategy & UX Design

Before a line of code, we map your riskiest assumptions and design the experience that proves them. Core user flows, modern aesthetics, and clickable high-fidelity prototypes you can put in front of real users before we build a single screen for real.

Deliverables: Product roadmap, user-flow diagrams, wireframes, high-fidelity UI, interactive prototype, reusable design system.

Scaling & Re-Platforming

Your app is live and the cracks are showing: performance, architecture, a codebase that can’t keep up. We rebuild what’s breaking and harden what’s working, delivered by an embedded senior pod without disrupting your in-house roadmap.

Deliverables: V2 rebuild, performance overhaul, scaling architecture, infrastructure hardening, native migration where needed.

Launch & Growth

Launch is the starting line. We instrument analytics, optimise your store listings, and help you read the early data so you iterate on evidence, not opinions.

Deliverables: Analytics and event tracking, App Store optimisation, crash monitoring, 30 days of post-launch support.

Why Valocity

What makes our custom app development different?

Most agencies build exactly what you brief. We pressure test the brief first, then ship the smallest thing that proves your riskiest assumption, on architecture that won’t need a rewrite when it works.

  • Senior-only pods

    Every person on your project has shipped at a venture-backed company. No juniors hidden in the team, no offshore handoffs, no agency interns learning on your budget.

  • Production-grade from day one

    We don’t build prototypes that need rewriting. The architecture you launch on is the one that scales to a million users and survives investor due diligence.

  • 8-week launch timelines

    Locked scope, a two-week sprint cadence, and an App Store pre-submission audit in week 11. You see working software every fortnight, not slides.

  • Transparent, founder-friendly commercials

    Fixed scope, milestone-based payments, and terms that respect your runway. No hidden fees, no scope-creep surprises, and you own all IP from day one.

What We Do

We build one thing exceptionally well — your app idea

No service menu to assemble. One senior team carries your idea from the first sketch to a polished app in the App Store and Google Play — strategy, design, engineering, launch, and scale, under one roof.

Custom-built. Never templated.

If you can describe it,
we can build it.

Your app isn’t a theme with your logo dropped on top. Every screen, every flow, and every line of code is built around your idea, your users, and the way your business actually works: engineered to feel inevitable the first time someone opens it, and to hold up when a million people do.

One build. One price. One team that owns the outcome. Everything it takes is already in the box:

  • Strategy & validation: We pressure-test your idea and scope the smallest build that proves it.

  • Product & UI design: Premium, high-fidelity design your users feel from the very first tap.

  • Native iOS & Android engineering: Clean code built to scale.

  • App Store & Play Store launch: Analytics, store listings, and a clean submission, all handled.

  • Post-launch iteration: Your app's success continues long after launch:

  • One senior pod, end to end: The people who scope your build are the ones who ship it. Handoffs are where speed and quality die.

Who We Build For

App development for every kind of builder

We don’t run one playbook for every client. Here’s how we shape an engagement around where you actually are.

First-Time Founders

Your challenge: You’ve got the idea and the drive, but no technical team and no room to get the first build wrong. You need something real in market fast, built right enough to grow on.

Our approach: A focused first build around your single core value proposition. We strip scope to what proves demand and gives you a foundation you won’t have to throw away in six months.

Existing Businesses Going Mobile

Your challenge: You’ve got a working business and customers who’d use an app, but no mobile presence. Maybe you’ve got a website doing the heavy lifting and you want it in your customers’ pockets.

Our approach: We turn your existing website or business into a native iOS and Android app, built to your brand, owned outright by you. The fastest path from established business to app store, without rebuilding what already works.

Scaling an Existing App

Your challenge: Your app is live and the cracks are showing: performance, architecture, or a codebase that can’t keep up with the growth you’re chasing.

Our approach: V2 rebuilds and performance overhauls delivered by an embedded senior team, without disrupting your in-house roadmap. We take what’s working, fix what’s breaking, and build for the scale you’re heading toward.

Enterprise & Global Launches

Your challenge: You’re building something serious, an app meant for a global audience and worldwide recognition, and it has to hold up under real scale, security, and scrutiny.

Our approach: Production-grade builds engineered for global launch: the architecture, security, and polish a worldwide audience demands, integrated cleanly with your existing teams and processes.

Frequently asked questions of custom app development

Real questions founders ask us before booking. If yours isn’t here, bring it to the Founder Call.

12 weeks for MVP scope (around four core workflows, one platform group), and 16 to 20 weeks for full scope (8+ workflows, multi-platform). Anything faster than that is a red flag, not a feature.

It depends on tier and scope — which is exactly what we size together first. Your exact, fixed quote is revealed free on your strategy session, once we’ve scoped the build properly. No quote without discovery, and no hourly billing.

100% senior, onshore. No juniors hidden in the pod, and no offshore arms. The people in your kickoff are the people writing your code.

We demo every two weeks, so you see working software long before it’s finished. You course-correct before the cost of change compounds. There are no big-bang reveals at the end.

Both, and we don’t separate them. The same pod handles design and engineering, because the handoff between the two is where speed and quality usually die.

30 days of post-launch support is included in The Launchpad, 90 days in The Full Stack, and a 12-month retainer in The Enterprise. Beyond that, most clients keep a pod on to scale the product.

Yes. Embedded pods are our standard mode for scaling clients. We integrate with your stand-ups, your tools, and your sprint cadence rather than working in a silo.

Scope is locked in the discovery workshop. New scope becomes a change order with explicit cost and timeline impact, so there are no grey-area, mid-build surprises on either side.

You own all IP and source code from day one. A pre-signed NDA is available before discovery if you need it.

Still have questions? Bring them to the Founder Call.
