Marketing for fintech, Web3, AI, and tech

Your fractional CMO and marketing team, built for the format shift your industry is going through right now.

Q: Does MIME45 work with Web3 and crypto companies?

Yes. Web3 and digital assets are core to what MIME45 does. The agency is fluent in crypto-native culture and knows how to market to it without losing technical credibility with institutional or regulated audiences.

Q: Does MIME45 help AI and tech companies with marketing?

Yes. MIME45 works with AI and deep tech companies on positioning, content, and PR that make technical products understandable to both technical buyers and the institutions and investors evaluating them.

You build the technology. We build the credibility, the audience, and the narrative that gets it adopted.

MIME45 gives ambitious Web3, fintech, AI, and technology companies senior marketing leadership without the cost or complexity of building an entire team in-house. We embed alongside your team as fractional CMOs and hands-on marketing partners, bringing strategy and execution together across content, PR, events, ecosystem growth, and go-to-market.

Why us

30+

years of combined marketing, events, content, and PR experience

From branding to launch strategy, PR to social media and content marketing, we've been passionate collaborators and committed partners to founders and enterprises across fintech, Web3, AI, and tech, and well beyond.

Fluent in complex tech

Web3, fintech, AI, and emerging technology require more than generic B2B marketing. We know how to understand technically complex products, make them legible, and build narratives for audiences with very different levels of sophistication.

Built by senior operators

Arabdha and Termeh already built this exact function once, from zero, at Halborn, before founding MIME45.

Proof over hype

164K+ leads, 25 to 30% revenue attribution, 2,500+ media placements: the standard we hold our own work to.

Fractional by design

Get experienced marketing leadership and a team that can execute alongside you, without the cost, hiring cycle, or overhead of building every capability in-house.

Why MIME45

A protocol changed what the internet could carry. We think marketing needs the same upgrade.

MIME, short for Multipurpose Internet Mail Extensions, was the standard that let a plain-text medium suddenly carry images, audio, and attachments. It's the quiet infrastructure behind almost everything that followed.

We named the studio after it on purpose. Web3, fintech, AI, and emerging tech are categories most agencies only ever speak one dialect of: a traditional tech shop that doesn't understand a token launch, a crypto-native agency that struggles outside Web3, or a technical team that only knows how to talk to other engineers. MIME45 is built to move fluently across all of them, at a moment when they're converging faster than most marketing organizations are built to handle.

AI is the second version of that same shift. MIME taught one message to become many formats. AI is teaching every format to write, design, and target itself, in real time, for whoever's actually reading it. We're not bolting AI on as a feature. We built MIME45 assuming it's already the substrate everything else runs on.

The 45 is 2045: the year futurists have long pointed to as the singularity, when technology and human intelligence stop being separate things. We're not claiming to know the date. We're naming the direction. Finance, Web3, AI, and deep tech are already converging faster than most companies' marketing can keep up with, and that's the world we built this agency for.

What we offer

Three packages. One growth engine.

Every package draws from the same five disciplines: marketing strategy, content engines, events, PR, and ecosystem marketing, sized differently depending on your stage and the moment you're building for. We can operate as your embedded marketing leadership team, build the foundation you're missing, or come in hard around a launch, raise, event, or other critical moment.

Inside each discipline

What actually happens once we start.

Each discipline breaks down into concrete, recurring work, not a slide of buzzwords.

Marketing Strategy

Positioning & messaging

A clear point of view on who you're for, what you do differently, and why it matters right now.

GTM architecture

The operating plan that tells every other discipline what to say, where to spend, and in what order.

Events Strategy

Presence at flagship events

Booth or demo presence, speaking slots, and workshops at the handful of conferences your buyers actually attend.

Meetups & community sessions

Local and virtual meetups, Q&As, and hands-on sessions that turn attendees into advocates.

Roadshows

A multi-city push timed to a launch, raise, or sale, with pre-registration and incentives built in.

Content Engines

Educational hub

A home for the in-depth articles, whitepapers, and explainers that make your category legible.

Blog cadence

A real content calendar, built to rank for the terms your buyers are already searching.

Webinars & video

Monthly sessions with credible guest speakers, plus explainer video for the ideas that don't fit in text.

Case studies & whitepapers

Written and video proof of what you've delivered for real clients, backed by a data-driven case for the category.

PR

Press outreach

Relationships with the outlets your buyers and investors actually read, and announcements timed to matter.

Thought leadership

Op-eds under your leadership's byline, pitched to the trade press and industry journals that shape opinion.

Newsroom & media kit

Company overview, key stats, executive bios, and visual assets, ready to hand any journalist on request.

Influencer & KOL partnerships

Credible voices in your space who've actually used what you've built, not paid placements dressed as reviews.

Ecosystem Marketing & Custom Activations

Co-marketing

Joint content, campaigns, and events with the partners your growth already depends on.

Alliance programs

A structured way to keep partners active instead of a one-off press release nobody follows up on.

How we work

Proof over hype.

Institutional buyers, crypto-native communities, and technical audiences are converging on the same demand for fewer loud launch packages and more evidence: clear positioning, earned visibility, and reporting a buyer can actually trust.

01 Diagnose

Position before you promote

We won't sell a campaign on top of unclear positioning. Strategy comes first, every time.

02 Build

One narrative, every channel

Content, PR, events, and activation run from the same message, so nothing contradicts anything else.

03 Earn

Bilingual, not just bicultural

We write in language institutions take seriously, Web3 trusts, and technical teams don't cringe at.

04 Prove

Reporting you can defend

Attribution and pipeline impact, not vanity metrics: the same standard we hold our own work to.

Founders

Built by strategists, not just marketers.

We already built one marketing organization together, from zero, before founding MIME45.
