Apps & Platforms

The apps and platforms your business runs on

Web, mobile, and desktop, wired together by the APIs and intelligent layers that make them act on their own. Built around how you work, connected to your stack, and yours to own.

Who we build for

Every industry, every stage, built to fit

Pick the profile that sounds like you — see the pain we solve, exactly what we build, and what changes after.

For larger organizations

Platforms that fit your scale

Complex, multi-department platforms and the integrations that tie your systems together, without the enterprise-agency overhead.

What gets connected
No hourly billing — a fixed price on the scope we agree.
The pain Dozens of tools that don't talk, and data rekeyed between them by hand.
We build Multi-department platforms with SSO, audit trails, and clean APIs across your stack.
The outcome One connected system your whole org trusts and acts on.
  • Integrations
  • Security
  • Scale
For growing companies

Punch above your size

The operational apps you can't buy off the shelf, built to fit exactly how you work and priced for a growing business.

The busywork, automated
Every line of the code and every account handed to you.
The pain Off-the-shelf apps you're bending with spreadsheets and manual steps.
We build Custom apps and portals shaped to your workflow, with the busywork automated.
The outcome Your people run the business, not the tooling around it.
  • Custom apps
  • Automation
  • Ownership
For specialists

Tailored to your craft

Niche, specialized apps and intelligent sites that reflect how your business is actually different.

Your words, in the data model
Built to your process, never a template with your logo on it.
The pain Generic tools that flatten the very thing that makes you different.
We build Custom apps and intelligent websites that mirror how you really work.
The outcome Software as specialized as the service you sell.
  • Custom
  • Intelligent
  • Fast build
For founders

Build the right thing, fast

From MVP to scale, a senior team that ships production-grade apps and platforms quickly so you can prove traction.

Shipped, not slideware
One senior team start to finish — no hand-off to a junior bench.
The pain A big idea, a short runway, and no time to build the wrong thing.
We build Production-grade MVPs and platforms, architected to scale when traction hits.
The outcome Proof you can put in front of users and investors in weeks.
  • MVP → scale
  • Senior team
  • Speed

Signs your software is holding you back

If two or three of these ring true, the answer usually isn't another off-the-shelf tool, it's an app or platform built around how you actually work.

  • Your website is just a brochure

    It looks fine but does nothing: no actions, no data, no follow-up.

  • Customers wait on your people

    Every question routes to a human, even the ones software could answer instantly.

  • Your tools don't talk

    Data gets rekeyed between apps because nothing is actually integrated.

  • You can't ship on mobile

    Your product lives on desktop while your customers live on their phones.

  • Manual steps between systems

    Someone copies data from one platform to another just to keep things moving.

  • It doesn't scale with you

    Growth means more headcount, not more automation.

Brian Diener Trustpilot

Several years on a website and learning platforms

A relationship measured in years rather than a project: as their needs changed, the team kept proposing the changes that let them grow.

We have worked with Growth Nerve for several years on our website and learning management platforms. As our needs have evolved, they have been able to adapt and proactively suggest changes and improvements that have allowed us to expand.

Communication, transparency, and a platform hardened

What stood out for this reviewer was how the work was communicated — and how far the team went on the platform's security.

Growth Nerve’s communication and transparency were most impressive. The team went above and beyond to ensure the platform’s security and delivered a flawless system.

Jacob Rodriguez Trustpilot

Laravel development on a community application

A community application built in Laravel. The reviewer's point is less what was built than how closely the build followed the conventions.

The team is well versed with Laravel development and follows the MVC guidelines to a tee. The development experience was not only smooth but went above and beyond.

Grant McClure Trustpilot

Responsive, professional, and recommended

This one is about the people rather than a build — no project is named in it, so we are not naming one either.

I’ve enjoyed working with the team. They’re responsive, professional, affordable experts. Would recommend!

Grant McClure — Verified reviewer (Trustpilot)
The Spaniard

Friendly, personal, and exactly what was asked for

About the working relationship rather than a deliverable: personal communication, and the extra mile on getting the detail right.

I’m very happy with these guys. Very friendly, personal communication, and they go the extra mile to deliver exactly what you want. I highly recommend them.

What we build

All kinds of applications, built here

    The connective tissue that ties your whole stack into one system.

    • REST
    • GraphQL
    • Webhooks
APIs & integrations

Connect everything you run

Whether it's building the API others plug into or wiring your stack together so data flows on its own, we make your tools work as one system, not a pile of tabs.

Build the API

REST, GraphQL, and event-driven APIs others can plug into, documented and versioned so integrations stay stable.

  • REST, GraphQL & event-driven
  • Versioned & documented
  • Rate-limited & secured
What you hand a partner
Versioned, so an integration written today still works after the next release.

Integrate your tools

Connect the CRMs, payment, and comms platforms you already run through official APIs, not brittle glue.

  • Official APIs, not scraping
  • CRMs, payments, comms
  • Two-way, real-time sync
The shape of the wiring
Official APIs, never scraping — so a vendor update does not take you offline.

Sync your data

Two-way sync and webhooks so records stay consistent everywhere, with one source of truth and no rekeying.

  • Webhooks & change events
  • One source of truth
  • No more rekeying
What "in sync" looks like
One source of truth, both directions, with the conflict rules written down.

Automate workflows

Trigger actions across systems automatically, from lead to invoice to fulfilment, with humans in the loop where it matters.

  • Lead → invoice → fulfilment
  • Cross-system triggers
  • Humans in the loop
One run, end to end
A person still approves the steps you choose to keep in human hands.

Secure & monitor

OAuth, scoped access, and monitoring so integrations stay safe and never silently break.

  • OAuth & scoped access
  • Alerting on failures
  • Retries & audit logs
How access is granted
An integration that stops working tells someone, instead of failing quietly.
Plays nicely with

  • HubSpot
  • Stripe

  • Slack
  • Zapier

Where to start

Two ways in. One team behind both.

Most companies are in one of two places. Pick yours — then choose how we work together.

  • Still Scoping

    “Something's not working, and we're not sure yet what to build.”

    Manual workarounds, a system you've outgrown, or a backlog with no clear starting point. We run a short discovery to find the one build worth doing first, and scope it honestly before you commit.

    Book a discovery session Know what to build first
  • Ready to Build

    “We know exactly what we need. We just need hands to build it.”

    Requirements are locked, the roadmap is clear, and you're short on engineering capacity. We plug in a senior team that ships from week one, not one that needs onboarding.

FAQ

Frequently asked questions

The things companies ask us before the first working session. Still curious? Just ask.

What kinds of apps and platforms do you build?

Web apps and platforms, mobile apps for iOS and Android, cross-platform desktop software, internal enterprise tools, customer portals, marketplaces, and the APIs and integrations that connect them. If your business runs on it, we can design and build it.

Can you build the API for our product, or integrate the ones we use?

Both. We design and ship REST, GraphQL, and event-driven APIs for products that others plug into, and we integrate third-party services — CRMs, payments, comms, and more — so your existing tools work as one system instead of a pile of tabs.

What does an "intelligent" website or platform actually mean?

It's an AI, automation, and agentic layer added on top of your product. Beyond displaying information, it can answer questions, search and personalize, and take real actions — booking, updating records, sending follow-ups — for both your customers and your people.

Can you connect a new app to the tools we already use?

In most cases, yes. We regularly wire new apps into existing CRMs, databases, payment systems, and third-party tools through official APIs, and we'll flag early if anything in your current stack needs extra work to integrate cleanly.

Do we own the app and its code?

Yes, entirely. Code, accounts, documentation, and infrastructure are handed over to you, with training to run and extend it yourself. No lock-in and nothing held back.

What happens after launch?

We don't disappear once it ships. Bug fixes, support, and an optional ongoing care plan are available so your apps, integrations, and intelligent layers keep working as your business changes.
