Software Development Review from Claus-Peter Mueller
We have engaged Infinum to develop an app that would digitalise our leasing process. From creating the initial offer through the necessary financing application and client identification to the final signature – all the steps required to successfully lease a vehicle or other object can be performed in-app, freeing the users of friction and having to deal with tedious paperwork.The app itself in the background has 30+ integrations, while keeping a seamless and quick to follow process on the front for our users. That application is in production and Infinum is responsible for maintaining it and further improving. After the initial development, we have additionally expanded our scope from vehicles to other equipment. They have also developed a Leasing widget, product which enables quick financing model while purchasing a vehicle online on car seller marketplace pages. At this moment, we are still in partnership with Infinum, and their engagement is mainly focused on localising the app to other countries and supporting us in our further business expansion. The work performed was done in Ruby on Rails and React technology, with support of other services.

Staff Augmentation Companies FAQs
What services do staff augmentation companies offer?
Staff augmentation companies provide external professionals who integrate into internal teams. Typical services include:
- Temporary and contract staffing: Short-term or project-based professionals who fill immediate capacity gaps without long-term hiring commitments
- Skill-based staffing: Role-specific talent for operational, administrative, or technical support
- Specialist augmentation: Senior or niche experts brought in to tackle complex challenges or bridge a skill gap
- Team extension: External talent working under in-house leadership as an extension of the internal team
What is the difference between staff augmentation and outsourcing?
An outsourcing and staff augmentation firm differ mainly in how teams are managed and how much control the company retains over execution.
The table below outlines the main differences between the two models:
| Aspect | Staff Augmentation | Outsourcing |
| Responsibility ownership | The company retains responsibility for delivery | Responsibility is transferred to the external party |
| Management | Requires internal coordination and management | Typically self-managed by the outsourcing partner |
| Cultural alignment | Integrated into the company culture over time | Separate cultures and methodologies may apply |
| Recruitment readiness | Time needed to source role-specific talent | Teams are often ready to start immediately |
| Knowledge retention | Knowledge may leave when contracts end | Knowledge is retained within the provider |
| Best fit by duration | Short- to mid-term needs and skill gaps | Long-term or ongoing project ownership |
When is the right time to hire a staff augmentation firm?
It’s usually the right choice when your internal teams need added expertise or support, such as in the following scenarios:
- You need specialized skills ASAP.
When a project requires expertise your team doesn’t have, such as a specific programming language or niche technical skill, you want to bring in specialists quickly without retraining or long-term hiring. - You’re facing tight deadlines or workload spikes.
If timelines are compressed or the workload suddenly increases, additional professionals can help keep projects on track without overextending your core team. - You need to scale temporarily.
For short-term initiatives, product launches, or one-off developments, staff augmentation provides flexibility without the overhead of permanent employment. - You want flexibility in how work is delivered.
When your internal teams need to adapt quickly to shifting priorities, staff augmentation allows you to adjust workloads, timelines, and skill coverage.
Many of these companies also go for it during hiring freezes, large-scale system upgrades, or when testing new technologies before building in-house expertise.
What are the key benefits of hiring a staff augmentation provider?
Main benefits include:
- Flexibility and scalability: Adjust team size quickly based on workload or project needs.
- Cost efficiency: Reduce expenses tied to recruitment, training, benefits, and permanent headcount.
- Faster delivery timelines: Extra resources help teams complete work sooner and maintain momentum.
- Reduced administrative burden: Payroll, compliance, and HR processes are handled externally.
- Lower hiring risk: Evaluate talent in real working conditions before making long-term decisions.
What are the main challenges of staff augmentation?
While staff augmentation companies in the USA offer flexibility and speed, organizations may encounter several challenges when integrating external talent into internal teams:
- Communication gaps: Remote team members can face time zone differences, language barriers, or misaligned expectations. Clear communication protocols, shared tools, and regular check-ins help maintain alignment.
- Cultural fit: External professionals may take time to adapt to internal workflows and company culture. That’s why you should focus on structured onboarding and early collaboration with core team members.
- Knowledge transfer: Temporary team members may lack the full project context. In this case, documentation, mentorship, and inclusion in key discussions would support smoother knowledge exchange.
- Legal and compliance risks: Contracts, IP ownership, and labor regulations can be complex. Make sure you have clear agreements and compliance support to minimize exposure and protect your company.
A strong staff augmentation partner typically helps address these challenges by supporting onboarding, communication structure, and compliance so that the external talent integrates effectively without disrupting internal operations.
