We refer work to specialists whose capability sits outside our own, and we deliver search and link building programmes behind the brands of agencies who need that expertise in their stack.
Every agency on this page has met the bar we set for our own delivery.
A referral partnership sends work in both directions when a requirement falls outside either party’s core service. A white-label partnership means Sentosa delivers the programme and the partner agency owns the client relationship.
Apexureapexure.com
Apexure designs and builds the systems a business runs on, covering landing pages, conversion rate optimisation, website builds and custom platforms across Unbounce, HubSpot, Webflow and WordPress.
We refer clients to one another in both directions and collaborate closely on shared accounts, with either firm able to deliver behind the other’s brand.

Hutch Agencyhutch.agency
Hutch Agency runs pay per click advertising campaigns for business to business brands on HubSpot, alongside paid media, marketing automation and revenue attribution.
They hold the client relationship and the wider strategy, and we support the search side with placements, outreach and quality control.
Visit Hutch Agency →We keep the arrangement simple and we keep the standard high, because a partner referral carries our name whether or not our name is on the invoice.
We partner with agencies whose core service sits beside ours rather than on top of it, so neither party is ever bidding against the other for the same budget.
White-label work is held to the same placement criteria, reporting detail and replacement guarantees as work delivered under the Sentosa name. The brand on the report does not change the bar.
In a white-label engagement the partner agency owns the relationship, the communication and the commercial terms. We do not approach partner clients directly, during the engagement or after it.
If you run an agency that needs search, artificial intelligence search or link building capability behind your own brand, or you have clients whose growth is limited by organic visibility, we would be glad to talk.
