What Is Co-Development and How Is It Different from Outsourcing?

Many Barcelona startups face the same dilemma: they need senior capacity in specific technologies to accelerate the roadmap, but full time hiring takes months the funding round does not allow, and dilutes equity before validating the profile is right. Co-development solves this: senior engineers integrated into your team and repository, with knowledge staying within your startup, scaling up or down per project stage.

Custom Software Engineering and Senior Co-Development for Your Critical Projects in Barcelona

Unreal engine

Senior engineering inside your team, not alongside it

We add senior capacity in weeks, not the months a traditional hiring process takes, critical when your startup's runway depends on hitting concrete milestones for the next round. We work integrated into your repository and code reviews, so the speed gained is not lost to the typical learning curve of adding someone completely external to the project.

Immediate capacity without months of hiring

Technical knowledge stays within your team, not with our company: we document, transfer context and work alongside your own engineers, not in parallel to them. For a startup that will eventually build its own complete technical team, this means co-development leaves real installed capacity, not an external dependency you have to replace later.

Full integration with your team and processes

Same repository, same code reviews, same rituals, we work as part of your team, not as an external vendor.

Senior profiles in high demand technologies

Architecture, AI, cloud, and specific stacks where hiring locally takes months your roadmap doesn't have.

Card background
Knowledge transfer in both directions

The joint work leaves your team knowing more about the system, not depending on us to understand it.

Flexible scaling per project stage

From a single engineer to a full cell, and back, depending on what the roadmap actually needs.

Card background
Technical and product control always stays yours

Architecture and priority decisions are made by your team, we bring judgment, not impositions.

No black boxes at the end

Everything built stays documented and understood by your team, ready to maintain without us.
