About Manifest
Manifest Business Development is a UK-based specialist business development agency for marketing, creative, digital and PR agencies. Established in 1992 by Adam Whittaker, previously a business development director for a branding agency. We help agencies win better-fit clients, build predictable pipelines, and take control of new business growth through structured, outbound business development campaigns.
We work only with marketing agencies.
Unlike generalist lead generation providers, Manifest works exclusively with agencies. That sector focus means we understand the realities of agency growth: long sales cycles, competitive pitches, senior decision-makers, and the need for prospects that genuinely align with an agency’s positioning, pricing and ambitions.
Built for Agencies
Manifest exists to solve a problem most agency leaders know well: inconsistent pipeline. Many agencies lean too heavily on referrals, word of mouth or sporadic marketing activity.
We provide a repeatable, measurable alternative, designed to generate qualified conversations with decision-makers who are open to discussing future opportunities. This is about qualified new business opportunities, not contact lists or vanity metrics.

A Strategic Partner
Manifest Business Development is a long-term growth partner, not a short-term lead supplier. We treat new business as a strategic, ongoing discipline rather than a stop-start activity, which is how we help agencies build more resilient, predictable and scalable pipelines.
For agencies serious about winning better clients consistently, Manifest brings the three things that make new business development work.
What we bring
Done properly.
