Why Senior Engineers Matter for Startup Software
Startups cannot afford junior mistakes when building their core product.
Each project is staffed by engineers with 8+ years of experience. Our team has shipped 200+ products across 50+ countries.
We use senior-only teams to reduce risk and accelerate delivery. 98% of our projects finish within the original timeline.
How We Differ From Generic Development Shops
Most agencies hire junior developers and bill by the hour. We do the opposite.
Generic shops often have high turnover and unclear ownership. IRPR assigns a consistent senior team with fixed pricing.
Every project includes a 2-week roadmapping phase to lock scope and budget. No surprises.
