Partnership services
Engineering capacity that fits your delivery model.
Say yes to more client work, cover skills you do not have in-house, and keep quality consistent across projects.
White-label development
We deliver under your brand and within your process. Your client works with your team; we stay behind the scenes.
Dedicated engineering capacity
Engineers assigned to your firm for ongoing work, so you can say yes to more projects without hiring ahead of demand.
Technical subcontracting
We take ownership of a defined part of a project, such as a backend, an integration, or a data pipeline, against your specification.
Project-based collaboration
Joint delivery on a single engagement, with responsibilities, milestones, and communication paths agreed up front.
Backend and full-stack delivery
APIs, services, databases, and web applications built to your client’s standards and handed over cleanly.
AI and cloud engineering support
Generative AI, RAG, agents, cloud infrastructure, and data engineering skills when a client project needs them.
Who owns what
Clear responsibilities from day one.
Every partnership starts with documented ownership, so your firm stays in control of the client relationship and we stay accountable for the engineering.

What you can rely on as a partner.

Reliable engineering practices
Code review, automated tests, CI, and documentation as standard, aligned with your conventions or your client’s.

Join a single project, provide ongoing capacity, or scale up for a busy quarter. Arrangements adapt as your pipeline changes.
Confidentiality and IP protection
Confidentiality, IP assignment, and non-solicitation of your clients are covered in the contract, subject to the terms we agree.

We tell you who is working on the project, where they are located, and how their hours overlap with yours and your client’s.

Partner questions
Questions agencies ask us.
Can you work under our brand?
Yes. In a white-label arrangement, our engineers work within your processes and communication channels, and your firm remains the client’s point of contact.
Will you contact our clients directly?
Only in the ways you agree to. Client communication rules and non-solicitation terms are defined in the partnership agreement.
Where are your engineers located?
Coastline Digital is based in San Diego, CA, and works with an international team of engineering professionals. We tell you where each engineer is located so you can make accurate commitments to your clients.
Who owns the code and IP?
IP ownership and assignment are set in the contract and can be structured to match what your own client agreement requires.
What size of engagement do you take on?
Engagement size is agreed per partnership, from a defined piece of a single project to ongoing capacity. Tell us what you have in mind and we will be candid about fit.
