Product Development

Product Development Services

Product development services that take you from idea to a shipped, used product — strategy, design, and engineering under one roof. For startup founders and SMBs who need a single team to own the whole 0-to-1 journey, not three vendors pointing fingers. We build to ship and learn, not to impress a pitch deck.

What You Get

A Product You Can Ship

01

From idea to shipped

We own the whole path — discovery, design, build, launch. You get a real product in users' hands, not a strategy deck or a half-finished prototype.

02

Validated as you go

We test the riskiest assumptions early and cheaply. Every stage produces evidence about what to build next, so you spend on what works.

03

One team, no handoff gaps

Strategy, design, and engineering work together from day one. Nothing gets lost between a design agency, a dev shop, and a consultant.

Our Approach

How We Develop Products

Most 0-to-1 products die from building too much before learning anything. We sequence the work to reduce risk first and scale only what's proven.

Riskiest assumption first

We identify what has to be true for the product to work, then test that before anything else. Better to disprove a bad idea in week three than month six.

MVP that's genuinely minimal

We cut to the smallest thing that delivers and proves value. Founders over-scope v1 constantly — our job is to protect you from building features no one has asked for yet.

Build for learning, then for scale

Early on we optimise for speed and feedback. Once the product finds traction, we harden the architecture so it scales without a rewrite.

Founder in the loop

You see working software every two weeks and steer priorities throughout. The product reflects your market knowledge, not just our assumptions.

It feels like they're part of the team, and they make good decisions without needing a lot of support.

I presented Illia with a problem, he helped me think through of a way to solve the problem and best of all: him and his team were able to actually implement it! He's got great entrepreneurial instincts.

I'm really happy I chose to work with Illia to develop a face measurement taking iOS application.

He has been very communicative, got the work done on time, delivered a quality application, and was able to solve some technical challenges related to determining landmark points on ARKit-derived 3D model.

Mobile Apps Across Every Vertical

Deep domain knowledge across core verticals — so you get a team that understands your market, not just your code.

How It Works

From Idea to Live Product

01

Discovery & Strategy

We pressure-test the idea, define the user, and map the MVP. You walk away with a product strategy, scope, and roadmap — even if step one is 'don't build this yet'.

02

Design & Prototype

We design the core experience and put a clickable prototype in front of real users. You validate before committing to a full build.

03

Build the MVP

Engineering in two-week sprints with a working product at every stage. You get a launchable MVP, not a perpetual work in progress.

04

Launch, Measure, Iterate

We ship, instrument the product, and iterate on real usage data. You get a live product and a clear view of what to build next.

Why Prosperity

Why Founders Choose Us

We've taken 40+ products from idea to launch. We act like a product partner who shares your goal of shipping, not a vendor billing hours.

Full stack under one roof

Product strategy, UX, UI, and full-stack engineering in one senior team. No coordinating separate agencies or losing intent across handoffs.

We've seen what kills products

Over 40 builds, we've learned the patterns that sink 0-to-1 products — over-scoping, building before validating, premature scaling. We steer you around them.

Honest about your idea

If discovery shows the idea needs rethinking, or that you should validate manually before writing code, we'll say so. We'd rather lose a build than ship you something that fails.

Senior people, no markup army

You work directly with the people doing the work. No large team billed through a markup, no juniors learning on your runway.

FAQ

Frequently Asked Questions

End to end, it covers product strategy and discovery, UX and UI design, full-stack engineering, launch, and post-launch iteration. We own every stage so you don't have to stitch together a strategist, a design agency, and a dev shop. You can also engage us for just the stage you're missing.
