B2B Revenue Growth

I find your next customers.
Then I help you keep them.

20 years building B2B revenue engines. Now with AI that writes outreach your prospects actually want to read — and the retention strategy to maximize their lifetime value.

Let's talk
Who I am

I'm Olivier Serres — a Revenue & Customer Success leader who got tired of seeing great B2B companies struggle with two things: finding the right prospects and keeping the clients they already have.

After leading CS teams at companies like Selligent, ACTITO, and Probance across France, Spain, and beyond — I built Growth Engine AI: an outreach system powered by AI that researches, qualifies, and writes hyper-personalized messages at scale. No templates. No spam. Every message is crafted for its recipient.

Two sides of growth

Acquisition and retention aren't separate problems. They're the same revenue challenge seen from different angles.

Growth Engine AI

AI-powered outreach that finds, qualifies, and writes to your ideal customers — so your sales team focuses on closing, not prospecting.

Just give us your website and a few example clients. Our AI builds your Ideal Customer Profile, researches each prospect's company and context, and crafts a unique message for every single contact.

  • Zero technical setup required from you
  • AI-built ICP from your website and look-alikes
  • Every message 100% personalized — no templates
  • Flexible packs: 100, 500, or 1,000 messages
  • Full deliverability infrastructure managed for you

Revenue Strategy

Customer Success, retention, and NRR growth consulting — from someone who's built and led CS organizations across 4 countries and 500+ accounts.

I help SaaS companies design the systems that keep customers, grow revenue per account, and turn CS into a measurable revenue driver — not a cost center.

  • Churn reduction & predictive analytics
  • Customer lifecycle design & segmentation
  • NRR growth playbooks (upsell & cross-sell)
  • AI implementation for CS operations
  • Fractional CS leadership for scaling teams

How Growth Engine works

From your website to qualified meetings — without you touching a spreadsheet.

01

You share, we learn

Send us your website URL and 5-10 companies that match your ideal client. Our AI scans everything and builds your Company Brain — your value proposition, differentiators, and tone, automatically extracted.

02

AI finds & qualifies

We source prospects that match your ICP, enrich them with real company context — their website, tech stack, recent news — and score each one. Only qualified leads move forward.

03

Personalized at scale

Each message is written specifically for its recipient using their real business context. Not a template with a name swapped in — a genuine, relevant message that earns a reply.

Whether you need more pipeline or better retention — the first step is a conversation.
