Your business runs on technology.Make sure it's the right one.
FusionOne helps business owners and consultants turn technology into a competitive advantage through hands-on strategy, product development, and technical leadership. Senior guidance, 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, then help you execute on them.
Sound familiar?
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 AI, automation, and digital tools. 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.
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, and 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, then 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.
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.

swishx.comAbout 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.
Some of what we build for our own workflow is released as open source, like perchd, a command-line tool for developers running AI coding agents in parallel.
