B2B growth & revenue advisory

Your growth isn't broken. Your revenue engine might be.

We help CEOs, Founders, CMOs and CROs find and fix the gaps between commercial strategy, marketing, sales and execution.

When pipeline is stalling, your GTM isn't translating into results, or your teams aren't aligned, we help you work out what's actually getting in the way, and what to do next.

Growth problems rarely sit in one department.

Pipeline can look like a sales problem. Positioning can look like a marketing problem. Execution can look like a people problem. Often, the real issue sits somewhere between them.

“We're generating pipeline, but it's not converting.”
“Marketing and sales aren't working from the same playbook.”
“Our GTM strategy looks good on paper, but execution isn't following.”
“We're scaling the team, but the same problems keep coming back.”
“I know something isn't working. I just can't see exactly where.”

That's where Laightbulb comes in.

Find the gaps. Fix what matters. Build for growth.

We help leadership teams diagnose and improve the systems behind growth, from GTM strategy and positioning to sales execution and leadership.

GTM & Revenue Strategy

Clarify your ICP, positioning, GTM motion, sales process and revenue priorities, and make sure they work together.

Marketing & Sales

Connect marketing activity to pipeline and revenue, and identify where the commercial handoffs are breaking down.

Revenue & Sales Execution

Identify the gaps in your sales process, pipeline and team execution that are slowing revenue down.

Leadership & Execution

Make sure the people responsible for growth have the clarity, priorities and accountability to actually deliver it.

Strategy is only useful when people can execute it.

Companies don't usually struggle because they don't have enough ideas. They struggle because the strategy, systems and people aren't pulling in the same direction.

Laightbulb works across those gaps, combining commercial thinking with an understanding of the people and leadership dynamics that determine whether a strategy actually gets executed.

Strategy↔Execution
Marketing↔Sales
Leadership↔Teams
Ambition↔Reality

Built for leaders responsible for growth.

Portrait of Amelie Marivain, founder of Laightbulb

The thinking behind Laightbulb.

I've spent my career working across B2B growth, sales, marketing and leadership.

I've seen the same problem repeatedly: companies don't usually struggle because they don't have enough ideas. They struggle because strategy, systems and people aren't pulling in the same direction.

Laightbulb exists to help leadership teams close that gap.

I'm Amelie Marivain, based in Singapore. I've led founder-led ventures and executive GTM functions, from customer discovery and ICP definition to positioning, sales playbooks, account-based motions and demand generation.

Start with the problem you're trying to solve.

You don't need to have the answer before you talk to us. Bring us the growth problem you're wrestling with. We'll spend 20 minutes pressure-testing it, identifying where the friction may be, and working out whether there's a problem worth solving together.
