Your business runs on technology. Make sure it's the right technology.

FusionOne helps business owners and consultants turn technology into a competitive advantage — through hands-on strategy, product development, team augmentation, and technical oversight. Senior leadership, when and where you need it.

Technology should drive your business forward — not slow it down.

You know technology matters, but the landscape is overwhelming. Which tools are right for your stage? Is your vendor delivering real value? Should you build or buy? Should you hire in-house or outsource?

Without senior technical guidance, businesses end up overspending on the wrong solutions, stuck with systems that don't scale, or dependent on vendors they can't evaluate.

FusionOne exists to fix that. We give you the technical clarity and hands-on support to make confident decisions — and then help you execute on them.

About FusionOne

FusionOne is a technology advisory founded by Irwan Setiawan — a technologist with 18+ years of experience building products, leading technical teams, and growing companies.

Having founded, built, and exited his own ventures — and led technology at both startups and global enterprises — Irwan brings a perspective that bridges business and engineering.

FusionOne was started from a simple observation: too many businesses make expensive technology mistakes because they don't have the right technical guidance at the right time. We're here to change that.

We work hands-on — not from the sidelines. Whether it's reviewing your architecture, writing code alongside your team, or helping you evaluate a vendor, we bring the same rigour and ownership as if it were our own business.

What we do

Every engagement is shaped by real-world experience building, scaling, and advising on technology — not theory.

Tech Strategy & Advisory

We help you define the right technology approach for your stage — whether you're choosing between build vs. buy, evaluating vendors, or planning a roadmap. Clear recommendations, no jargon.

Product Development

From idea to working product. We scope, design, and build — web apps, mobile apps, internal tools — with a focus on getting something real into users' hands fast.

AI & Automation

Search, recommendations, chatbots, document processing, workflow automation. We help you identify where AI creates genuine value for your business — and build it.

AI Infrastructure

Cloud inference is fine for getting started — but scaling demands a real hardware strategy. We help you evaluate on-prem vs. cloud, optimize inference costs, and own your AI infrastructure decisions instead of defaulting into them.

Team Building & Augmentation

When you're ready to grow your technical team, we help you define roles, screen candidates, run technical interviews, and onboard engineers properly.

Technical Oversight

Already have developers or a vendor? We review architecture, code quality, and delivery to make sure your investment is on track.

Who we work with

Business Owners

You're growing a business and technology is becoming critical — but it's not your expertise. You need someone who can translate business goals into the right technical decisions, and make sure nothing falls through the cracks.

Consultants & Professional Services

Your clients are asking about technology — AI, automation, digital tools — and you want to bring credible technical capability to the table without building an in-house team.

Startup Founders

You're moving fast and need senior technical input — someone who's built and shipped products before, not just advised on them. Whether it's your MVP, your architecture, or your first hire.

Flexible engagements, transparent pricing.

Every business is different, so we tailor our engagements to fit. Whether it's a short advisory sprint or a longer-term partnership, you'll know exactly what you're getting and what it costs before we start.

2–4 weeks

Advisory Sprint

A focused engagement to assess your current technology, evaluate options, and deliver a clear plan of action.

6–12 weeks

Scope, design, build, and launch. From concept to a working product in your users' hands.
