Social Media Designs | 3Line
Client: 3Line
Industry: Fintech / Payment Infrastructure
Scope: Brand identity system, social media ads, promotional flyers, service launch campaigns
Engagement: 3-month contract retainer
Formats: Motion and static ads
Overview
3Line is a payment infrastructure company that powers banking and payment services across the fintech ecosystem. Over a 3-month retainer, I built out their brand identity system and produced a steady stream of creative across social media ads, promotional flyers, and campaign assets for product launches and ongoing marketing.
The work spanned both motion and static formats, covering everything from service launch announcements to promotional campaigns.
Brand Identity System
The first priority was establishing a cohesive visual system that 3Line could use consistently across all their marketing channels. This meant defining:
Visual language and layout system for social media formats, ensuring every post felt like it belonged to the same brand regardless of the content type
Typography and color application rules that worked across both static and animated formats
Template structures for recurring content types like promos, product announcements, and informational posts
The identity system needed to feel credible and institutional (this is payment infrastructure, not a lifestyle brand) while still being visually engaging enough to perform on social media.
Product Launch Campaigns
Two major product launches happened during the retainer:
Gravity: A payment product that needed launch creative to introduce it to 3Line's audience. The campaign assets needed to communicate what the product does, build anticipation, and drive engagement across social channels.
Medusa: Another payment product launch that required its own distinct campaign identity while still sitting within the 3Line brand system. Each product needed to feel like its own thing without breaking from the parent brand.
For both launches, I produced a mix of static social ads, motion graphics, and promotional flyers that rolled out across the campaign timeline.




Promotional & Ongoing Creative
Beyond the product launches, the retainer covered ongoing promotional needs:
Promotional flyers for campaigns, offers, and service announcements
Social media ads (both static and motion) for paid and organic channels
Ad creative for specific marketing pushes and seasonal promotions
The volume was consistent across the 3 months, with creative produced on a rolling basis to keep 3Line's social presence active and on-brand.






Design Approach
Fintech credibility: The visual tone had to communicate trust and technical competence. Payment infrastructure is serious business, so the creative avoided anything that felt too casual or startup-playful. Clean layouts, structured compositions, and a restrained palette kept things grounded.
Motion and static parity: Every campaign needed to work in both formats. Static ads were designed with motion in mind from the start, so animated versions weren't afterthoughts but natural extensions of the same compositions.
System thinking: With a 3-month retainer producing this volume of creative, consistency mattered more than any single piece. The brand identity system did the heavy lifting here, making it possible to produce at pace without quality drift.
Result
Over 3 months, I delivered a brand identity system, two product launch campaigns (Gravity and Medusa), and a continuous stream of social media ads, motion graphics, and promotional flyers for 3Line. The work gave them a cohesive visual presence across their marketing channels and the creative infrastructure to maintain it.
