Lars had a strong opinion on why most people get investing wrong, and he'd been sharing those opinions at dinner parties for years. His friends kept telling him to put it online. He'd never found the time.

The Situation

The platform was growing, but the unit economics were deteriorating. Paid CAC had risen 35% year-on-year as competition in the European retail investment space intensified. Churned users from paid channels were dragging LTV down. The product was genuinely good — the problem was reaching people who would engage with it seriously.

The Turning Point

Lars wrote a LinkedIn post disagreeing with a popular personal finance influencer's advice on index fund timing. It was direct, backed with data, and slightly controversial. It reached 140,000 people organically and generated 2,300 profile visits in a week. Several converted to signups that week.

What We Did — And Why

The content strategy was built around Lars's existing conviction: demystifying investing for people who felt excluded by financial jargon. Three weekly content formats — the opinion piece, the market explainer, and the behind-the-scenes platform update — gave the audience a reason to follow consistently. The employee advocacy programme amplified reach by training the team to engage genuinely rather than share corporate posts.

The Results

31k combined LinkedIn followers in 10 months. 2,800 signups directly attributed to LinkedIn. CAC fell from €87 to €49 as organic became a meaningful acquisition channel. LinkedIn-acquired users had 3.2x higher LTV than paid channel users — they came in already educated, already trusting.

In Their Own Words

The best marketing for a financial product is the founder showing they actually understand money — and are willing to share that understanding for free.
