Customer Solutions Engineer — Enterprise SaaS

Justin Fournier.

I turn skeptics into customers — then into long-term partners. Deep discovery, honest PoCs, demos built around the buyer's actual problem. I don't disappear after the signature.

What I do

Technical depth,
commercial outcomes.

Ten years across implementation, customer success, and now sales engineering. The throughline: I find the technical truth, turn it into revenue, and stay to make it renew.

01

Technical Discovery & PoCs

Discovery that surfaces the real buying criteria — then evaluations with defined success criteria and executive readouts. No science projects, no shelfware.

02

Competitive Displacement

Unseating entrenched incumbents with technical win themes and de-risked migration paths. I make switching feel inevitable — never scary.

03

AI-Augmented Evaluations

I bring AI into the sales cycle itself — live agent workflows run against the customer's own data, so buyers see their future state instead of a slide deck.

04

Success & Expansion

A decade in post-sale before pre-sales: onboarding, adoption, QBRs, executive advocacy. $1.56M in expansion in a single fiscal year — growth earned through trust, not pressure.

How I work

Principles, not platitudes.

The operating system I bring to any company — portable across products, teams, and logos.

01

Lead with the conclusion.

Analysis is proof, not the pitch. If it doesn't fit in one sentence, it's not ready to say out loud.

02

Say when it's not a fit.

I'll talk a buyer out of the wrong purchase. Trust compounds — oversold deals just churn later.

03

Stay after the signature.

Most SEs vanish at close. Most CSMs never saw the technical win. I was in the room for both — the deal I helped win is the account I help grow.

04

Discovery before demo. Always.

No generic walkthroughs. I earn the right to show product by understanding the problem first.
