Winning investors digitally: a guide for issuers and fintechs

An issue is soundly calculated, the prospectus approved, the product understandable. And yet the investors are missing, because there is no sales network or a bank would be too expensive. This guide shows how issuers, crowdinvesting platforms and fintechs win investor capital digitally, which rules apply and how to measure success. It is based on our work at ad.boutique in Vienna and Zurich.

First, because it matters in this topic: all numbers in this article describe the efficiency of past advertising campaigns. They say nothing about the returns or risks of an investment, and this article is not legal or investment advice.

In short

You win investor capital digitally with a funnel that builds trust step by step: ad, issuance landing page, explainer video, qualification, personal follow-up and a simple subscription journey. Every ad has documented approval before launch. Success is measured by subscription volume and cost per investor, not clicks or leads.

Subscription volume is the total capital that investors subscribe, meaning commit to bindingly, in a given period. Attributable capital is the part of it that you can demonstrably assign to a campaign or channel.

Who this guide is for

This guide applies to anyone raising capital from many investors who has no sales network of their own, or wants to complement it. The mechanics are similar, the rules differ.

The detailed articles go deeper into individual cases: marketing a bond for issuers with a subscription period and crowdinvesting marketing for platforms and project initiators.

The legal framework in brief

Advertising for financial products is subject to three levels of rules: law, regulator and platform. Anyone who only knows one of them risks rejected ads or worse. This overview is general information (as of October 2026) and does not replace legal advice. The legal points refer to the EU and Austria; other countries have their own national rules. Have your ads checked by your legal adviser before launch.

Prospectus requirement and advertising

For public offers of securities such as bonds, the EU Prospectus Regulation (EU) 2017/1129 applies, supplemented in Austria by the Capital Market Act 2019 (KMG 2019). Article 22 of the Prospectus Regulation contains its own rules for advertising. In essence, it requires:

• A reference to the prospectus: advertising must state that a prospectus has been or will be published and where it is available.
• Recognisability: advertising must be clearly recognisable as advertising.
• Consistency: the information must not be inaccurate or misleading and must be consistent with the prospectus.

For crowdfunding, the EU Regulation on European crowdfunding service providers (EU) 2020/1503, the ECSP Regulation for short, applies. It has applied since November 2021 and governs, among other things, the key investment information sheet for investors and platforms' marketing communications. In Austria, there is also the Alternative Financing Act (AltFG). More on this in the article advertising financial products.

Platform rules on Meta and Google

Meta and Google have their own policies for financial products and financial services, which apply in addition to the law. In a growing number of countries, Google requires verification as a financial services provider before such ads may run. Which countries are affected and which evidence you need is set out in Google's financial services policy.

Meta has financial products and financial services as a special ad category with restricted targeting and reviews investment ads more closely. So plan time for the review and expect individual ads to be rejected and reworked.

Mandatory information, risk warning, no promises of returns

Every ad and every landing page needs the information that the law and the prospectus require, plus a clear risk warning. Usually this is a reference to the risk of losing capital, up to and including total loss, and a reference to the prospectus or key information document.

We do not advertise with promises of returns. Concrete statements about returns create expectations that nobody can guarantee and, for financial products, are under particular legal scrutiny. Instead, our ads explain the offer, the process and the risk. A product's key figures such as a coupon may only be communicated consistently with the prospectus, completely and with a risk warning, and only after legal review.

The funnel

An investor funnel is the path from the first ad to subscription, built so that trust grows with every step. Investors do not decide in one click, which is why the funnel has more stages than in e-commerce.

How we build such journeys is described on the service page landing pages and funnels.

Issuance landing page

An issuance landing page is the central page of a capital raise, to which all ads lead. It explains, in this order: what is the offer, who is behind it, how does subscription work, what are the risks, where can I find the prospectus or key information document.

The tone matters. An issuance landing page does not sell with pressure, but with clarity. Facts in tables, risks not in the small print, contact people with faces and names.

VSL and explainer video

A VSL (video sales letter) is a video that explains an offer step by step and anticipates typical questions. For products that need explaining, it is often the most important trust builder.

In the real estate investment case, we filmed with the board: six short videos for the feed and to accompany search, a long version and an explainer video that unpacks the path from investment to tax effect in a few minutes. Nobody understands a developer model from an ad, but many do from a good video. The videos are produced by our content production team.

Qualification and SMS verification

Qualification means capturing already in the form how serious and how large the interest is. Questions about the planned ticket size, timing and previous experience with comparable investments have proven themselves.

SMS verification is a code that prospects receive by text message and enter before the enquiry is submitted. It filters out fake leads and typos and makes sure investor relations only calls real contacts.

Subscription journey and subscription dashboard

The subscription journey is the process in which an investor subscribes bindingly, depending on the product via the platform, the paying agent or an online form. Every unnecessary step costs subscriptions, so the journey needs testing just as much as the ad.

A subscription dashboard shows leads, conversations, subscriptions and capital live and per channel. Only then can you say honestly which euro of advertising budget led to capital. We build it in our lead CRM with dashboard, with a daily data feed.

Channels

Four channels work for investor capital, with clearly divided roles. No channel is enough on its own.

In finance, Google Search is often the channel with the clearest attribution. In the real estate investment case, Google produced attributable capital of around €5 million. For the crowdinvesting platform, Google was the closing channel for the demand Meta created. Our learning there: brand search harvests demand, it does not create it.

For fintechs, the goal shifts: instead of a subscription, it is often the account opening or the first deposit. The logic stays the same. What is measured is not the app installation, but the step that counts for the business, and this step is reported back to Meta and Google so that the platforms optimise for it.

We use LinkedIn in a targeted way, for example for a bond in the real estate investment case. Email nurture is a series of emails that accompanies prospects over weeks, with explanations, answers to common questions and appointments. It is indispensable for long decision paths.

Messages that build trust

Investors respond to clarity, not superlatives. The strongest messages in our finance campaigns explain rather than promise. "Education builds trust, trust leads to action" was the guiding principle in the real estate investment case, "trust and traceability before product details" in the crowdinvesting case.

These are the angles we test most often in finance campaigns:

What we deliberately do not test: angles with promises of returns, urgency without a real reason ("today only") or comparisons that hide risks. They sometimes bring cheap leads, but rarely reliable subscriptions, and they often fail at the approval stage.

Investor relations and follow-up

In the digital funnel, investor relations is the person or team that talks to prospects, answers questions and accompanies them to subscription. Without this human part, a large share of leads is left lying, especially with large tickets.

A clear process has proven itself: a call or appointment offer on the same day, documents after the conversation, a reminder before important deadlines and an email series for everyone who is not ready yet. Every step is recorded in the CRM, so that it later becomes visible which campaign brought conversations and which brought subscriptions.

Timeline of a capital raise

A digital capital raise needs more lead time than most people plan for, because approvals, platform reviews and trust take time.

Compliance approvals built into the process

Compliance approvals belong at the beginning of the process, not at the end. If every ad goes back and forth by email, a campaign costs weeks before it starts. That is why we moved this into the platform.

This is how an approval works with us:

1. Submission: copy, creative and landing page are created as an approval on boutique.OS, with version and channel.
2. Review: the responsible person at the client checks for mandatory information, consistency with the prospectus and the risk warning.
3. Second review: a second person confirms, following the four-eyes principle.
4. Documentation: who approved what and when stays traceably stored.
5. Changes: every change to an approved ad starts a new approval.

Because approvals are faster, more can be tested. That is the real gain, not the bureaucracy. How we work overall is described on the page how we work.

Data protection and tracking for investor leads

Investor leads are particularly sensitive data, because they can contain indications of assets and investment intentions. Without clean tracking, however, there is no attribution all the way to subscription. Both can be reconciled if data protection is planned in from the start.

We apply these principles in every finance project:

1. Consent before tracking: pixels and analytics only run once visitors have agreed, in line with the GDPR and, for Swiss target groups, the revFADP.
2. Data minimisation in the form: only ask what investor relations really needs for the first conversation.
3. Feeding back with a legal basis: subscriptions only go back to Meta and Google if there is a reviewed legal basis for it and the privacy policy describes it.
4. Separated access: on our platform, every person only sees the clients and data they work on, every access is logged and the data is stored in the EU.
5. Deletion periods: leads without a subscription are not kept indefinitely.

If consent is missing, data is missing. That is no reason to get around it, but a reason to build attribution through the CRM rather than only through pixels: anyone who submits a form has the source passed along with it, regardless of the cookie banner.

Metrics

In financial marketing, CPL is misleading if it stands alone. CPL (cost per lead) is the cost per enquiry. What matters are cost per investor and attributable capital.

How to build this chain and trace subscriptions back to the campaign is shown in the article cost per investor and subscription volume.

Numbers from two cases

The following numbers describe the efficiency of past advertising campaigns, not returns for investors. They come from the reports to our clients.

Real estate investment: capital instead of clicks

A high-quality investment offer had no predictable flow of qualified investors. Since 2023, we have built a funnel that builds trust from education to subscription, with Google, LinkedIn, video and a lead dashboard with a daily data feed.

Measured honestly: the client already had a second paid channel running. We made it measurable, built the attributable channel in parallel and closed the other one when it was confirmed that it brought no subscriptions.

Crowdinvesting: same budget, more capital

A crowdinvesting platform promoted its projects individually, without a shared data basis. We switched to a platform-based structure: shared data, a clear KPI logic, learning across projects, plus talking-head videos and UGC instead of stock images.

The budget was almost the same in both phases. The average investment via ads on the platform is €13,400. In the second POC phase, €67,180 of media budget brought 114 investments and €1.26 million in capital. More in the crowdinvesting case.

Common mistakes

Most capital raises do not fail digitally because of reach, but because of measurement, trust and speed. These are the mistakes we see most often:

1. Optimising for CPL. The campaign brings cheap leads who never subscribe.
2. Compliance at the end. The ads are finished, then the approval starts, and the subscription period is running.
3. Advertising with returns. It attracts the wrong prospects and is legally risky.
4. No video. Products that need explaining are squeezed into three lines of ad copy.
5. No follow-up. Investors want to talk before they subscribe.
6. Individual campaigns instead of a platform. Every project starts from zero, nothing is learned.
7. No tracing back. Subscriptions are not traced back to the campaign, and budget flows by gut feeling.

When digital placement is not enough

Digital marketing does not replace a viable product or a credible story. With very large volumes, very high minimum tickets or purely institutional target groups, a sales network or a bank is often still needed. Digital channels then complement rather than replace.

To be honest: no funnel makes an offer better than it is. If the terms, the team or the use of proceeds are not convincing, digital campaigns only show it faster and more clearly. That is uncomfortable, but valuable, because it saves budget before an entire capital raise depends on it.

How we work at ad.boutique

We support issuers, crowdinvesting platforms, fintechs and banks from Vienna and Zurich, in Austria, Germany and Switzerland, and international issuers who want to reach investors in DACH. We start with a 12-week proof of concept, for which we agree a metric in advance, usually cost per investor or attributable capital.

1. Weeks 1 to 2: set the metric, set up the approval process on boutique.OS, set up the landing page, video concept and tracking.
2. Weeks 3 to 8: test channels and messages, evaluate every Monday, trace subscriptions back to the campaign.
3. From week 9: shift the budget to the channels that bring capital, not just leads.

For banks, we also work on brand and events: since 2025 we have produced the videos for Kommunalkredit's Kommunale Sommergespräche and promoted the event via LinkedIn and Google. More about our approach on the page financial marketing for issuers.
