Outsourcing comes with questions. We bring answers
Working with an external partner shouldn’t feel risky. Here’s how our experience turns common outsourcing challenges into strategic wins:
Uncertainty around quality and accountability
Our solution:
With Vention, you always know where your project stands. We follow ISO-certified processes and assign dedicated delivery managers who maintain tight communication, clear milestones, and consistent quality.
Limited in-house capacity
Our solution:
Whether you need a single specialist or an entire cross-functional team, we have 3,000+ engineers across all major tech stacks, ready to fill roles fast. You stay in control of the project, and we bring the engineering peace of mind.
Slow team onboarding and missed deadlines
Our solution:
We typically go from handshake to kickoff in under two weeks. Our streamlined onboarding process ensures our team codes within days, minimising delays.
Concerns around security and IP protection
Our solution:
Security is prioritised at every stage of the partnership. We sign comprehensive NDAs before any work begins, follow ISO 27001-certified practices, and operate within secure, access-controlled development environments. Our engineers adhere to strict role-based permissions, and we implement regular security audits, code reviews, and encrypted communication protocols.
Legacy tech holding back progress
Our solution:
We modernise outdated systems using clean, scalable architecture and modular APIs, making it easier to move fast and innovate with confidence.

Have questions? We’re here to answer them
What exactly is software development outsourcing, and how does it work with your outsourcing software company?
Software development outsourcing means partnering with an external provider to handle part or all of your development needs.
Instead of hiring and managing an in-house team, you gain access to our global network of 3,000+ engineers, designers, QA specialists, and delivery experts, helping you accelerate delivery, tap into specialised skills, and reduce operational overhead.

We typically go from initial contact to team kick-off in 10 to 14 days.
Can I begin with a small engagement and expand later?
Absolutely. Many of our long-term clients started with a small team and scaled up as their needs grew.
Can we interview or approve the developers before the project starts?
Yes. Transparency and collaboration are key to our approach. We usually send the CVs of our available engineers within 24 hours.
Can you take over an existing project or legacy codebase?
Absolutely. We prioritise transparency and collaboration. CVs of available engineers are usually shared within 24 hours for your review.
