Win mandates.
Sharpen delivery.

From outreach and market intelligence to buyer research and executive access, we help you uncover more opportunities, pitch more competitively, and deliver processes with greater impact.

The Challenges Holding Advisory Teams Back

These are some of the recurring themes we hear when speaking with M&A advisory teams:

We don’t have the time or resource to run structured origination.

It’s a beauty parade — we need a stronger angle.

Our buyer list is fine — but we could go deeper or more strategic.

We’ve built Guidesource to solve exactly those problems — through insight, access, and execution.

What We Deliver

We help corporate finance firms win more work and deliver it with greater insight — by plugging in where you need it most. Our services are designed to sharpen origination, elevate pitches, and strengthen your process execution.

Deal Origination

We map fragmented markets and uncover off-market, founder-led targets — prioritised using ownership, size, and signal data. We run outreach discreetly under your brand or ours to unlock conversations that lead to mandates.

Pitch Support

We help sharpen your proposition with validated insights, market maps, and executive commentary. From sector deep-dives to strategic angles, we give your team the edge in competitive beauty parades.

Process Delivery

Once engaged, we help build high-fit buyer lists, introduce relevant strategic and financial buyers, and bring in former operators to test positioning and improve strategic narrative.

An Integrated Model,
Built for Impact

We don’t just find opportunities or people — we connect the dots between them to drive smarter execution. Our integrated model brings together market intelligence, strategic access, and executive insight in one joined-up process.

We act as a quiet extension of your team, working behind the scenes to help you spot opportunities earlier, pitch with more conviction, and deliver greater value throughout the deal lifecycle.

Strategic Insight.
Delivered Discreetly

We stay discreet and aligned with your brand — always acting as a quiet extension of your team. Whether you want to elevate one pitch or scale origination, we help you deliver more without adding internal overhead.
