Who We Work With

Built for one type of company

We don't work with everyone. We work with B2B SaaS companies between 50 and 500 people who are ready to invest in LinkedIn as a serious pipeline channel.

๐Ÿš€

Series A / B Scale-ups

You've found product-market fit and need a predictable, scalable channel to reach decision-makers at the right companies. LinkedIn is it.

๐Ÿ“ˆ

Heads of Marketing

You need a specialist partner who can own LinkedIn end-to-end, report on pipeline impact, and align with your sales team's outreach.

๐ŸŽฏ

Founders Going Upmarket

You're moving from SMB to mid-market and need to reach VP and C-level buyers at specific target accounts. LinkedIn ABM is the answer.

What We Do

Everything your LinkedIn ads need

We handle the full campaign lifecycle โ€” strategy, creative, targeting, optimisation, and reporting โ€” so you can focus on closing deals.

01

Campaign Strategy & Setup

We audit your existing account (or build from scratch), define your ICP, set objectives, and structure campaigns for maximum learning velocity and ROI.

02

Signal-Led Audience Targeting

Using our proprietary signal data โ€” job postings, funding rounds, headcount growth โ€” we build audiences of companies actively in buying mode, not just job titles.

03

Ad Creative & Copywriting

Scroll-stopping creative built for the LinkedIn feed. Single image, video, carousel, and document ads โ€” tested continuously to find what resonates with your buyers.

04

Lead Gen Forms & Landing Pages

LinkedIn Lead Gen Forms that convert at 10-15%. We build, test, and optimise every step from ad click to booked meeting in your sales team's calendar.

05

Account-Based Marketing (ABM)

Target your exact dream accounts by company. Upload your list, we'll reach every decision-maker inside those businesses with tailored messaging across the funnel.

06

Reporting & Pipeline Attribution

Monthly reports focused on pipeline impact โ€” cost per lead, lead quality, meetings booked, and revenue influenced. No vanity metrics, no fluff.

Our Process

How we turn LinkedIn into a pipeline machine

A proven, repeatable process refined across dozens of B2B SaaS campaigns. You'll see your first results within 30 days.

1

Discovery & Audit

We start with a 30-minute discovery call to understand your ICP, sales cycle, existing assets, and pipeline goals. If you have existing campaigns, we audit them and identify exactly where budget is being wasted.

2

Signal Research & Audience Build

Using our proprietary signal data, we identify the companies most likely to be in-market right now โ€” actively hiring, recently funded, or showing growth signals. These become your warmest LinkedIn audiences.

3

Creative Strategy & Asset Production

We develop your messaging framework and produce ad creative โ€” copy, visuals, and format strategy โ€” designed to educate and convert your specific buyer at every stage of awareness.

4

Launch & Rapid Testing

Campaigns go live within 2 weeks of kickoff. We run structured A/B tests across targeting, creative, and copy to identify winning combinations as quickly as possible.

5

Optimise, Scale & Report

Weekly optimisations. Monthly pipeline reports. As we learn what works, we scale the winners and kill what doesn't. Most clients see meaningful CPL improvement between months 2 and 3.

Why Prospect Fly

What makes us different

There are dozens of LinkedIn agencies. Here's why B2B SaaS companies choose us.

Signal-led targeting nobody else has

We built our own signal intelligence system that monitors job postings, funding announcements, and headcount growth across thousands of UK and European SaaS companies. Your ads reach companies actively in buying mode โ€” not just job titles in a spreadsheet.

B2B SaaS only โ€” no generalists

We work exclusively with B2B SaaS companies between 50 and 500 people. That means we understand your sales cycle, your buyers, and what moves the needle. You won't be managed by someone who ran e-commerce campaigns last month.

Pipeline focus, not lead volume

We report on what actually matters: pipeline created and revenue influenced โ€” not impressions, clicks, or form fills from people who'll never buy. Your CFO will understand our reports.

Founder-led, senior-level work

Your account is managed by the founders โ€” not passed to a junior after onboarding. You get direct access, fast responses, and strategic thinking on every campaign decision.

Client Results

What our clients say

Currently onboarding our first cohort of clients. Case studies publishing May 2026.

"Prospect Fly understood our buyers better than agencies twice their size. The signal-based targeting surfaced companies we'd never have thought to target โ€” and they converted.

"We'd burned through budget with two other agencies. Prospect Fly rebuilt our campaigns from scratch with a focus on pipeline, not leads. CPL dropped 40% in month two.
