How it works

How white-label works with me

01

NDA and onboarding

I sign your NDA and non-solicitation agreement and join your tools: Slack, ClickUp, Asana, Notion or whatever your team uses.

02

You own the client relationship

I never contact your clients unless you ask. When it helps, I join calls as part of your team.

03

Delivery on your timeline

Clear milestones, Loom updates and files organized your way, so your project manager always knows the status.

04

You present the work

Everything is delivered unbranded or under your brand, with all source files included.

Why agencies choose me

Why agencies work with me

Senior work only

No juniors and no outsourcing. You get 10+ years of hands-on experience on every task.

Fewer freelancers to manage

Web, SEO, video and AI from one person means fewer hand-offs and fewer things lost between vendors.

Predictable pricing

A fixed price per project or a monthly block of hours, so you can quote your clients with confidence.

English and Spanish

Bilingual delivery lets you serve Spanish-speaking clients and markets.

Frequently asked questions

Will my clients know I work with you?+
Only if you want them to. By default I work fully white-label: no branding, no direct contact with your clients and all files delivered under your agency's name.
Do you sign NDAs and non-solicitation agreements?+
Yes. I sign both before you share any client information, and I never approach your clients directly.
How do you price agency work?+
Either a fixed price per project, or a monthly retainer with a reserved block of hours at a lower rate. Both are quoted up front so you can protect your margin.
Can you join client calls?+
Yes. I can join calls as part of your team, and use an email address on your domain if you prefer.
What if you are fully booked?+
I only commit to work I can deliver on time. Retainer clients get reserved capacity every month, so their projects always have a slot.
