Advertising Agency Frankfurt for the Mittelstand

mindmelt is an owner-led advertising agency based in Frankfurt am Main, established in 2002. We build web design, corporate identity and marketing for owner-managed businesses and mid-market companies across the Rhine-Main region. Founded and run by Ingo Krumm. mindmelt was named Leading Innovator 2026.

One agency. One owner. One contact.

Strategy, corporate design, web development and SEO - one team, one owner, one contact from start to finish.

For decision-makers with no in-house marketing team, or a small one that needs backup, that's the real difference: a single point of contact rather than an agency pyramid, a team that knows your brand better after the first project than at kick-off, and straight answers to specific questions - not open-ended workshops.

In practice: call today, you'll usually hear back the same day. If a project takes twelve weeks, we say so in the first email - not in week ten.

What you end up with: a website that ranks and converts. A corporate identity that attracts the right clients and sets you apart from competitors. SEO built properly into the structure - not just a line on the invoice.

Why mindmelt and not another Frankfurt agency

mindmelt differs from most Frankfurt agencies on four counts: owner-led since 2002, full client ownership of the end product, technical work done in-house rather than outsourced, and personal project leadership by the owner.

01

Owner-led

In Frankfurt since 2002. From dotcom to AI - experience that shows in the work.

02 

Your property

Code, design files, domain - everything is yours. No dependency on mindmelt after handover.

03 

Technical depth

Your site is built to a technical standard most agencies don't understand - let alone deliver. The result: Google reads your content properly.

04 

Owner involvement

You work with the person who runs the agency. Ingo Krumm writes the strategy, crafts the pitch, signs off the work - and brings in the team that builds, designs and optimises.

Who we work with

Owner-managed businesses and mid-market companies with no in-house marketing team - or a small one that needs backup. B2B companies with products and services that need explaining. Decision-makers who want to talk directly to the person who delivers.

Our best work happens with clients who know what they want - but are open to someone who puts it better, builds it cleaner, and thinks a step ahead of the brief.

We know the Mittelstand 

B2B marketing in Frankfurt works differently to consumer advertising in Hamburg or Berlin. Less hype, more balance sheets. Fewer TikTok strategies, more LinkedIn. Less storytelling romanticism, more clear-cut arguments a managing director can absorb in 30 seconds and take straight to the board. That's our territory. We work with family businesses, engineering firms, law firms, technical consultancies, tax advisers, insurance specialists and mid-market industrial service providers. Sectors driven not by awards but by trust, continuity and long-term business relationships. A B2B agency needs to be at home in that world - with substance, the right tone, and an understanding of decision-making processes that take longer than two weeks. And with a genuine appreciation for brands that build trust through consistency, not by reinventing themselves with every campaign.

Your contact: Ingo Krumm

I'm the owner of mindmelt, an advertising agency in Frankfurt am Main.

My team and I have been supporting mid-market businesses in Frankfurt with their digital presence and brand identity for over 25 years. The web has reinvented itself three times in that period - the requirements for good brand work haven't changed: clarity, substance, consistency over the long term.

At mindmelt, you don't land in a sales funnel. You reach me directly. I run every strategy project personally, know every client repository, and have written every pitch myself. That's demanding, frankly - but it's the only way to run an agency I'd actually hire myself.

FAQ

Frequently asked questions about working with an agency

Costs, process, ownership, sector knowledge - the questions managing directors and marketing leads ask most often before choosing an agency.

A compact website from €3,900 net, a business website with basic SEO setup and blog from €5,900, a corporate website for multiple target groups with Schema.org from €8,900. Ongoing SEO from €790 per month. We invoice per project - no timesheet chaos. After an initial conversation, you’ll receive a concrete cost estimate.

At mindmelt, owner Ingo Krumm leads every project personally - from briefing to go-live. That’s what sets owner-led agencies apart from network agencies, where the person who wins the pitch isn’t the person who does the work. Faster decisions, no account manager mark-ups, no handover between sales and delivery. Many of our clients have worked with us for over 10 years - because continuity beats the cost of starting over.

Four questions help: (1) Does the agency have B2B references, or only consumer work? (2) Is your contact someone who actually delivers - or just sales? (3) Who owns the source code, domain and design files after the project ends? That ownership question is a reliable indicator of the right fit: anything not answered clearly creates dependency later. (4) Can you speak to former clients? mindmelt arranges reference conversations on request.

Honestly: if you can build an in-house team covering strategy, design, development and SEO, do it - it’s cheaper in the long run. If not, an agency makes most sense when there’s no marketing team in place, when a relaunch or brand development is on the agenda, or when ongoing support would cost less than a full-time hire. For mid-market businesses without an in-house marketing function, an external agency is often more cost-effective - at mindmelt, with a fixed contact and none of the employment costs.

Check references, not awards - real projects say more than prizes. Have an initial conversation - reputable agencies do it free of charge. Look for sector understanding - B2B is not B2C. Read the contract terms, especially clauses on ownership and vendor lock-in. Start with a smaller project before commissioning a full relaunch. When choosing an advertising agency in Frankfurt, sector knowledge, reference projects and ownership rights to the end product are the most important criteria.

Depends on the project. Smaller work - landing pages, flyers, copy revisions - can often start within one to two weeks. Larger projects such as relaunches or brand strategy need lead time for workshops and the concept phase: typically four to eight weeks. If we’re currently at capacity, we’ll say so directly. For a quick read on availability: 069 21936250 - a short call is faster than any questionnaire.

So we don’t propose something that doesn’t fit your means. A web project can make sense at €5,000 or €50,000 - without a budget range, we’ll either over-engineer or under-deliver. Both waste your time. Transparency upfront saves revision loops later. At mindmelt, you receive a written cost estimate after the initial conversation - no surprises.
