The ProspectAgency is expanding beyond its core offering of B2B lead generation. We’re actively looking to take on small marketing agencies with annual revenues between £250k and £1M — particularly those that have consistently delivered strong results for their clients over time. Our goal is to support these agencies in scaling further, while creating synergy between our existing client base and yours. By integrating services across the group, we aim to deliver even greater value to all clients involved.

Selling your agency isn't just a financial decision, it's personal. You've built something from scratch, possibly over years, and now you're ready to move on, but not at any cost.

Here is one (if not many) of the worries you have when considering selling:

  1. “I don’t want to see it fall apart after I leave.”

  2. “I’m ready to step away, but I don’t want to sell to someone who doesn’t get it.”

  3. “My team matters. I don’t want them left behind.”

We get it. We’ve had these conversations many times before. And that’s exactly why we created a different kind of acquisition approach.

What We’re Looking For:

We’re currently acquiring marketing agencies that meet the following criteria:

  1. £250k – £1M in annual revenue.

  2. Ready to sell now or in the next 3–6 months.

  3. Open to seller-financed deals.

  4. Well-built systems, strong client delivery, and a good reputation.

If that sounds like you, we’d love to talk.

Why Sell to The ProspectAgency:

We’re not a faceless holding company. We’re agency operators ourselves, and we understand where you are.

We’re Fast, Flexible, and Founder-Friendly:

We move quickly with real conversations, not time-wasting tire-kickers. We can structure a deal that works for you, including seller finance, phased transitions, or immediate exits.

We Preserve What You Built:

We’re not here to gut your agency. We protect the brand, the team, and the systems that make it successful — and we build on it, not bulldoze it.

We Will Grow Your Company:

We’re experts in lead generation, outbound campaigns, and client acquisition. That means we plug your agency into a proven growth machine, not hope for the best.

You Stay Involved (If You Want To):

We prefer you to stay on for 12–24 months while transitioning out, but we will tailor the transition based on your timeline and life plans.
