How we work
Three cooperation models.
You choose how much ownership we take. The people stay senior in every model.
Client-led
Extraordinary Talent
You manage the work. We provide extraordinary people.
For teams that keep control of delivery and need experienced specialists alongside them.
Relevant when
- A specific senior expertise is needed inside your existing team
- You need more capacity without changing who owns delivery
- Continuity in a critical engineering role is simply a must
- People need to be productive quickly in a complex environment
LLI delivery ownership
Delivery Ownership
You define the problem. We own the delivery.
For defined initiatives that need an accountable engineering team, not individual specialists.
Relevant when
- A defined initiative needs an accountable team
- A legacy platform must change without disrupting operations
- An AI prototype needs to reach production
- Several disciplines must deliver as one team
LLI product & technology ownership
Product Ownership
You bring the ambition. We own the outcome together.
For organisations that need a product and technology partner across the lifecycle.
Relevant when
- A product needs technology leadership, not just talent
- A new product must go from ambition to discovery, build, and scale
- Product, technology, and delivery decisions belong together
- Long-term collaboration without building the whole organisation
In Delivery and Product Ownership our teams use AI-enabled engineering workflows. Senior engineers stay accountable for every decision and everything shipped.
