What we build

Custom software, end-to-end. Built to ship.

From the first whiteboard sketch to production at scale, DevSquad is the custom software development company that handles strategy, design, engineering, QA, and DevOps under one roof.

  • Scales with you
  • Built to last

Mobile app development

iOS and Android apps with one shared codebase. Native feel, native performance, half the maintenance cost.

  • iOS & Android
  • Native feel
  • App store launch

Internal tools & enterprise software

Replace duct-taped spreadsheets and aging Frankenstacks with internal apps your operations team will actually use.

  • Workflows
  • Integrations
  • Reporting

Product design & discovery

A 1-3 week design sprint to pressure-test the idea, prototype the riskiest screens, and produce a roadmap engineers can actually build.

  • Discovery sprint
  • Prototype
  • Roadmap

Our methodology

Our engineers lead the AI. They don't follow it.

We pair every senior engineer with AI agents using Spec-Driven Development, the same methodology Microsoft, Amazon, Google, and Stripe use to ship production code 2-3× faster, with zero shortcuts on quality, security, or scale.

Custom software built on real foundations. Not a vibe-coded prototype that gets hacked two weeks after launch.

× Vibe-coded prototypes

Lovable, Cursor & v0 in the hands of amateurs.

  • ×Edge cases get missed
  • ×Bugs hide in plain sight
  • ×Security gaps go unnoticed
  • ×No one is accountable when it breaks
Spec-Driven Development + AI

Senior engineers write the specs. AI executes. They own every line.

  • Specs anticipate edge cases before code is written
  • The AI accelerates. The engineer reviews and owns.
  • 100% production-ready, security, scale, observability built in
  • Same senior team from kickoff to launch and beyond

Why DevSquad is different

A real product team. Not a Frankenstack of freelancers.

You don't only get developers. You get a fully managed squad with a product manager, designers, QA, and DevOps wrapped in, for less than the cost of one senior hire.

With DevSquad

Plug & play
  • Fully managed senior squad with PM, designers, engineers, QA, and DevOps under one roof
  • Monthly subscription, no contractor markup or recruiter fees
  • Working product in your hands every two-week sprint
  • 200+ products shipped together. They've built this exact thing before.
  • Pause, scale, or swap squad members as your roadmap shifts
  • You own all the code, IP, and infrastructure from day one

The Frankenstack

DIY
  • ×6 months hiring a senior engineer, then a designer, then a PM…
  • ×$200K+ all-in cost per senior hire, before equity
  • ×Freelancers ghost; offshore shops cycle juniors through your codebase
  • ×"We'll start the project next quarter". Every quarter.
  • ×No QA, no DevOps, no design, until something breaks at 2 a.m.
  • ×Codebase looks like four different products glued together
I had attempted to save money by managing programmers myself. There was one project that took two years to complete. By the end of it, it still broke all the time, had tons of bugs and was just not usable. I got in touch with DevSquad and they built a better product in three months with no bugs, and it is a much better piece of software. It cost about 1/5 of what I paid when I was trying to manage it myself.

Frequently asked questions

Custom software development, answered.

Everything founders and CTOs ask us before kicking off an engagement.

What types of businesses does DevSquad work with?

DevSquad works with growing businesses that need software tailored to their operations, workflows, and long-term goals. Many of our clients are operationally complex companies dealing with disconnected systems, spreadsheets, manual processes, or scaling challenges.

We specialize in solving business problems through custom software, not selling generic development capacity.

How is DevSquad different from a typical software development agency?

Most development agencies wait for instructions. DevSquad takes a consulting-first approach. We help identify inefficiencies, challenge assumptions, shape the roadmap, and guide technical decisions before development begins.

Our dedicated squads combine product strategy, UX, development, QA, and DevOps into one fully managed team focused on business outcomes.

When should a company choose custom software over off-the-shelf tools?

Custom software makes sense when your workflows are becoming constrained by generic SaaS tools, disconnected systems, or manual workarounds.

If your business relies on spreadsheets, duplicate data entry, fragile integrations, or processes that give you a competitive advantage, custom software can help streamline operations and support long-term growth.

Does DevSquad help with software strategy and planning before development?

Yes. Every engagement starts with discovery, planning, and roadmap development. We analyze your workflows, systems, operational challenges, and business goals before recommending solutions.

This process helps reduce wasted development time and creates a clearer path to measurable ROI.

Can DevSquad modernize or rebuild existing software?

Absolutely. Many clients come to DevSquad with outdated internal systems, legacy platforms, or software that can no longer support growth.

We help modernize applications, improve scalability, redesign user experiences, integrate systems, and rebuild critical software foundations when necessary.

What does working with a dedicated DevSquad team look like?

You'll work with a fully managed squad that stays aligned with your business over the long term. Depending on your needs, your team may include strategists, technical product managers, designers, developers, QA analysts, and DevOps specialists.

Because the same team stays with your product, there's less knowledge loss, less re-training, and faster long-term execution.
