How we work

A clear, repeatable engagement model

Practical, embedded, outcome-oriented. We work alongside founders and revenue leaders — not above them.

Diagnose

We start with a structured assessment of the current motion — pipeline, conversion, comp plan, team and processes — to surface what is and isn't working.

Design

We build a tailored GTM blueprint covering ICP, segmentation, sales process, metrics and team structure — grounded in the realities of B2B SaaS.

Deploy

We implement alongside the team — coaching AEs, joining customer calls, refining playbooks, and instrumenting the pipeline for visibility and accountability.

Hand off

Our goal is durable internal capability. We document, train, and transition ownership so the engine keeps running long after the engagement ends.

What B2B SaaS leaders say

A selection of feedback from founders and operators we've worked with.

“

Charles was brought in as a sales advisor to help us rebuild our compensation and quota plan. In just a few calls with our sales team, he quickly identified the limitations of our existing practices and developed a new model aligned with Magicplan's long-term goals. The recommendations proved invaluable and contained a concrete action plan to help us reach our targets. I highly recommend his sales coaching services if you're looking to bring your sales to the next level.

After a single week working with Charles, I immediately saw the radical change in mindset he instituted across our sales organization. Opstream's go-to-market completely changed for the better, allowing us to achieve concrete results faster. If you're looking to level up your sales team, Charles will be your superpower.

Charles is truly a one-of-a-kind sales leader. The team he built at Datagen was very strong, and operated like a well-oiled machine. He set aggressive targets, and over-delivered on them. It has been a pleasure working with Charles — the work he did was incredible, and I would be thrilled to work with him again in the future.

Leadership

Senior practitioners, hands on the work

Every engagement is led by an experienced operator who has built and scaled the function in question.

Charles Brun

Managing Partner

Charles has spent 15+ years building and leading go-to-market organizations across B2B SaaS — from first-customer motion through scaling teams to $10M+ in revenue. He has hired and ramped AEs, SDRs and SEs, closed enterprise logos across tech, automotive and retail, and operated as both founder and senior GTM leader.

At Blue Horizon Ventures he partners directly with founders and revenue leaders on the most consequential decisions in their GTM motion — from ICP and pricing to compensation, hiring and pipeline execution.
