Problems we solve
Sound familiar?
These are the moments teams call us.
“We need to ship faster but can’t hire fast enough”
Your roadmap is full. Hiring takes months. We plug in senior engineers who start delivering in days because they’ve built systems like yours before.
“Our platform needs to modernize but we can’t stop delivering”
Tech debt is slowing you down, but a rewrite isn’t an option. We do incremental modernization in production, migrating systems while they’re live.
“We need senior guidance, not just more hands”
You don’t need another developer. You need someone who can evaluate your architecture, challenge your technical decisions, and set the right foundation.
“We’re building something new and can’t afford to get v1 wrong”
First architecture decisions compound. We bring engineers who’ve launched products before and know which shortcuts to take and which ones to avoid.
Dealing with one of these? Let’s figure out the right fix together.

Why ExergyIQ
What makes us different.
Senior-only teams
Every engineer has 12+ years of production experience. We don’t staff juniors learning on your budget.
Platform depth
We don’t staff generalists. Our teams know the platforms they work on because they helped build them.
Customer focus
We view each client as a business partner. We learn your business and deliver solutions that fit your processes.
End-to-end delivery
From solution design through migration, optimization, and support. Every phase staffed with the right people.
Proactive safeguards
We architect for resilience, not just functionality. Small problems don’t become major impacts on our watch.
Global, cost-effective
Delivery from Poland and India with competitive pricing and strong communication that keeps engagements sustainable.
Frequently asked questions
Common questions about working with us.
What does “senior-only” actually mean?
Every engineer on our team has 12+ years of production experience. We do not hire juniors or mid-level developers. Our average team member has 15 years of hands-on engineering experience across complex systems. This is our staffing model, not a marketing claim.
How does your team extension model work?
Our engineers embed directly into your existing product teams. They work in your tools, attend your standups, and ship in your release cycles. They operate as an extension of your org, not a separate vendor silo. Onboarding is fast because every person we place has integrated into complex environments before.
What industries do you specialize in?
We are a domain-agnostic senior product development team that works across any industry. Our depth includes capital markets and investment management technology, fintech, healthtech, enterprise SaaS, and Oracle ecosystems. We also work with startups scaling their engineering teams from Series A onward.
Where are your engineering teams based?
Headquartered in Boston, MA, with engineering centers in Warsaw, Kraków, and Gdańsk (Poland) and a regional hub in Vienna (Austria). We align teams to your time zones and communication preferences.
How fast can you start?
Initial team mobilization typically happens within 2 to 4 weeks. Because our engineers are senior, they ramp faster and start contributing to production earlier than you might expect from a new team integration.
Let’s talk about what you’re building.
Whether you need two senior engineers next month or a full team for a multi-year platform effort, the conversation starts the same way.
