The final test happens in your codebase. Your chosen developer works with your team for 14 days, and you pay only if you're happy with the results.
Steigern dedicated engineers vs. freelancers vs. in-house hiring.
See why CTOs and scale-up founders pick Steigern Tech over unpredictable freelance marketplaces and slow, expensive local recruiting.
| What You're Comparing | Steigern Tech Dedicated | Freelance Marketplaces | In-House Local Hire |
|---|---|---|---|
| Technical Screening & Quality | Top 1% of applicants, pre-vetted, with proven production experience | Self-reported profiles; portfolios are hard to verify | Thorough, but costs your engineers 2–3 months of interview time |
| Time-to-Hire & Onboarding | Profiles in 24 hours; code shipping in 3–5 business days | 1–3 days, but with frequent dropouts and ghosting | 60–90 days on average |
| Replacement Guarantee | Free replacement within 48 hours, backed by the trial period | None; the project stalls and payments are often lost | Recruiting starts over from scratch |
| Recruitment & Agency Fees | Zero recruitment fees; transparent monthly billing | Platform commissions (Upwork, Fiverr and similar) | Typical 15%–25% recruiter agency placement fees |
| Timezone & Communication | 4–6 hours of guaranteed daily overlap with US, UK, and EU teams | Unpredictable response times | Full local working hours |
| IP & Security | 100% IP transfer on Day 1, bilateral NDA, ISO 27001-aligned processes | Loose individual agreements; higher risk of IP leaks | Standard employment contract |
| Scaling Flexibility | Grow or shrink your team with 30 days' notice | Availability for long projects isn't guaranteed | Long-term contracts and severance costs |
