Serdica

We modernise European business.

At every scale, to a consistent standard.

01 / SERVICES

What we do.

We use AI where it does real work, not where it only looks modern.

Strategy & brand.

Diagnosis before prescription. Brand and positioning, digitalisation strategy, and analytics — matched to how much the decision matters.

Software & systems.

Software built to fit the business it serves. Internal tools, integrations, customer-facing applications, and the infrastructure beneath them — engineered for the long term, owned by the client.

Growth.

Marketing that compounds. Channel work — paid, organic, lifecycle, content — aimed where customers decide, not where it's easy to spend.

02 / WORK

Work across scales and sectors.

  1. Punchline.email

    AI-NATIVE EMAIL PLATFORM

    An AI-powered email platform built on Brevo. Reads a team's campaign history, learns what works, and drafts on-brand campaigns from a stated goal.

  2. Rezon.so

    CONSUMER INTELLIGENCE PLATFORM

    Consumer intelligence for performance marketers. Analyses real buyer conversations across the web to surface pain points, language, and positioning angles.

  3. Ski Stamenov

    INDEPENDENT INSTRUCTOR · ALPINE

    Custom site and paid advertising for an independent ski instructor. The campaign produced more enquiries than the client could take on. Marketing was paused at his request.

  4. TABA Record Store

    SPECIALIST RETAIL · SOFIA

    Implementation, custom front-end, and ongoing digital marketing for an independent record store. The shop sells online for the first time.

  5. Sven Kalus Training

    INDEPENDENT PROFESSIONAL · GERMANY

    Website build and SEO for an independent personal trainer in Germany. The site now ranks at the top of local search and surfaces in AI-generated recommendations — demand the client hadn't anticipated.

  6. Sveta Petka Tarnovska

    BULGARIAN ORTHODOX PARISH · GERMANY

    A custom platform and application for a growing Bulgarian Orthodox parish in Germany. Member directory, events, parish communications, and donations — built to serve the community's daily operations and to grow with it.
