Sector · Creative agency & martech

Custom apps and martech platforms for creative agencies.

We build for agencies that want to deliver more than campaign after campaign: campaign management dashboards, asset libraries that scale, client portals where accounts move through production without endless emails, and white-label apps that place your agency within the stack of its own clients. Code ownership stays with you, and with your client where that is the agreement.

No off-the-shelf SaaS package fits the way your agency works.

An agency is not an e-commerce shop or a SaaS start-up. It is an organisation where a new campaign arrives every week, where ten client brands must each be served in ten different tones of voice, and where the real margin lies in how quickly an idea moves from pitch to production to live. Standard project management tools, generic DAM systems and off-the-shelf martech suites are built for one customer who works in one way, which by definition is neither your agency, your clients nor your unique process.

Most creative and media agencies therefore run on a patchwork: Asana or Monday for planning, Frame.io for video review, Google Drive or Dropbox for assets, a shared spreadsheet for campaign KPIs, a Notion database for briefs, and a separate tool per client because that client happens to be on HubSpot or Marketo. The core functionality works, projects move forward, videos get approved and campaigns go live, but every new team member has to learn six tools, every new client means a new set of integrations, and every new campaign is assembled from loose steps that differ slightly from project to project.

On top of that, the agency software market itself is in flux. Adobe Workfront is acquiring agency functionality, HubSpot is pricing itself out of the smaller agency segment, and specialist tools such as Wrike, ScreenCloud and Brandfolder are being acquired one after another. Agencies that have leaned heavily on a single SaaS tool see their workflows disappear as soon as the vendor moves upmarket. In that context, a custom app or martech platform is not a luxury but an insurance policy against vendor roulette and price increases that no pitch margin can absorb.

A custom app solves that differently: your agency's processes are built into the software rather than the other way round, with one central place where campaigns, assets, client feedback and performance come together, and your client can work in their own white-label portal without having to learn yet another tool. We build that layer on top of Appfront's app service and connect it to the data and media tools you already use. For agencies with a marketplace component of their own, such as a production house that matches freelancers with clients, or a media agency that sells inventory with third parties, we draw on our approach to a custom marketplace platform as a reference architecture.

Software that fits every type of agency.

A dedicated workflow, dedicated integrations and dedicated KPIs for each type of agency. Below is what we typically build for each discipline, from creative to performance.

Creative & brand agency

The focus here is on the creative process: from brief to concept to production, with multiple clients in parallel and multiple campaigns per client. Agencies working in this space need an environment where briefs, mood boards, copy iterations and visual assets come together, with version control that definitively ends the difference between "v3-final" and "v3-final-FINAL". Campaign status must be clear at a glance for both the client lead and the account team, and approval flows must be client-friendly without unnecessary extra steps.

Our module set for creative agencies typically builds on a campaign dashboard that acts as the heart of the agency app: for each campaign, a timeline from briefing to going live, automatic notifications at review moments, and a reporting layer showing how many hours have been spent per discipline and per client. We also build an asset library with smart tagging, AI-supported search and a client-specific export flow, so final logos, brand guidelines and campaign visuals don't end up across ten WeTransfers but stay in one central place, labelled with the correct licence and usage rights.

For the relationship with clients themselves, we build a client portal: an environment in which your client no longer needs to email for the latest version of a banner, doesn't need to ask when the social posts go live, and no longer has to hunt through a shared Drive with thirty subfolders. The portal shows the status, asks for targeted feedback and archives decisions in a log that remains readable even after a change of contact person.

  • Campaign dashboardBriefing → concept → production → live in one timeline per client.
  • Asset library with AI taggingImage and video search by colour, subject, brand rule and licence.
  • White-label client portalYour own look and feel, your own domain, your agency as the invisible host.
  • Review and approval flowFrame-accurate video and banner review, audit log per approval.

Which martech and agency apps we typically build.

The agency world is broad, and that is reflected in the kinds of apps we build for agencies. For one agency, a campaign management dashboard is central, bringing together all brands, campaigns, deadlines and reports, often connected to Google Ads, Meta, LinkedIn and TikTok Ads via their marketing APIs, so performance no longer has to be copied into a spreadsheet every week. For another agency, it is an asset library with DAM: an environment where photo, video, copy and design assets are managed centrally, with rights management, expiry dates for talent and music licences, and an API that lets a client's own marketing team access approved assets directly.

A third group of agencies would benefit most from a client portal for agencies: an environment where each client gets their own view of their ongoing campaigns, invoice status, briefs, approvals and reports. No more email chains about whether "that one banner from last week" has been approved, no yearly "could I have the Q2 creative again" request, and no hassle with SharePoint permissions. The same architecture often forms the basis for a white-label app for agency clients: the agency supplies the software, and the client experiences it as their own tool. The overlap with B2B software is considerable. For the details of that context, we deliberately point you to our page on building a B2B app.

For performance and media agencies, we often build an attribution and measurement platform: a custom layer on top of Google Ads, Meta, LinkedIn, TikTok, Display & Video 360 and the client's own CRM data, with first-party tracking and server-side events so that the erosion of third-party cookies doesn't undermine all your reporting. Under the hood, such a platform relies on a data layer for which we often build a custom data engineering platform, with BigQuery or Snowflake as the warehouse, dbt for transformations, Airflow or Prefect for orchestration, and a visualisation layer in Looker, Metabase or a custom front end.

For agencies that publish their own content, such as content marketing units, editorial platforms and branded magazines, we build content collaboration platforms where editorial, design and final review share one workflow, with a publishing pipeline to the agency's or client's own CMS. Where editorial and commerce overlap, for example a lifestyle publisher selling its own products or a fashion agency publishing shoppable content, we draw on our experience with headless commerce platforms to combine CMS and e-commerce in one solution.

For production houses, photo and video studios and post-houses, we build project management and planning tailored to production: shoot planning, crew call sheets, equipment tracking, on-set photo and video upload with automatic metadata tagging, and a review environment where the director and the client work side by side. For digital studios and UX agencies, we deliver testing and hand-off tools that run alongside Figma and Storybook and speed up handover to clients' development teams. And for agencies with their own network of freelancers or suppliers, we build a marketplace layer where briefings, availability, contracts and invoices all come together in one place.

The common thread running through all of this: the software follows your process, your client mix and your brand, not the other way round. We build vendor-independent, which means that a future IT partner of your client or of your own agency can take over the code, the data and the hosting without Appfront becoming indispensable. That reflects how we view agency software: an agency should not be locked into a tool once it starts to grow seriously.

Agency software with the legal backbone of a serious product.

Agencies bear responsibility for client data, personal data of end users and intellectual property. From the first sprint, we build within the framework of GDPR, IAB TCF, rights management and accessibility.

GDPR and controllership

Clear allocation of responsibility for each type of data

An agency becomes a processor as soon as it handles personal data belonging to clients or to their end users, for example email databases, CRM leads, prospect data or audience segments. In our martech platforms, we record for each dataset who is the controller and who is the processor, with a retention policy for each data object. Data processing agreements, sub-processor registers and standard DPIA templates are delivered at handover, not left for a later update.

IAB TCF 2.2 and Consent Mode v2

A consent layer that keeps pace with the law

Since Google Consent Mode v2 and the stricter IAB TCF 2.2 requirements, an agency can no longer build its campaign measurement separately from consent management. We integrate with Cookiebot, OneTrust or your own CMP and make sure consent signals flow through the entire stack, from pixel to warehouse, so that segments, audiences and attribution models only run on data you are legally allowed to use.

Rights management and licensing

Images, music and talent with expiry dates

An asset library without rights management is a ticking time bomb: a music track with an expired sync licence, an influencer shot whose talent agreement has lapsed, or a stock photo with restricted usage rights. These issues can lead to claims against your client. We build rights and licence fields in as first-class metadata, with expiry dates, scope of use (web, print, broadcast, social), territory and rolling renewal workflows.

EU AI Act and generative AI

Responsible AI in campaign and content workflows

AI is now an inseparable part of agency work: AI for copy, image generation, video editing and automatic tagging. Under the AI Act, AI systems that personalise advertising or make decisions about consumers can potentially fall under transparency or high-risk categories. For each AI application, we map the risk classification, document governance, and build disclaimer and disclosure flows where needed, particularly for synthetic images and voices that touch on the limits of the Digital Services Act.

WCAG 2.2 / EAA

Accessible campaign output and client portals

Since the European Accessibility Act, the WCAG 2.2 AA standard applies to a growing number of end-client portals, banner environments and interactive campaigns. For agencies working for (semi-)public clients such as government, healthcare, banks and telecoms, this is a hard delivery requirement in 2026. We build client portals and interactive campaign sites to be accessible by default, and provide an accessibility statement where it is legally required.

Ownership & source code handover

The code and data remain with your agency

We deliver the code in a repository managed by your agency or your client, which continues to exist without Appfront. No mandatory licences, no hidden hosting locks, no compulsory maintenance contract. This is deliberate: when an agency or its end client changes agency, the software should simply go with them. We can handle hosting and management, but that is a choice on your side, not a condition.

Seamlessly connected to the agency and martech stack.

We integrate with the tools your agency and your client already use. No migration of the entire stack. Our app complements rather than replaces.

Standard integrations, no project-specific connections.

We have standardised the integrations mentioned above across several agency and martech projects. For a new engagement, we set up the integration using the same abstraction layer, which means fewer bugs, a faster turnaround, and your own tech team can manage it themselves once we step away. The integration layer is a mappable adapter: if your client moves from HubSpot to Salesforce next year, that is a configuration change, not a rebuild.

For specific agency or client software, such as a client's own DMP, a legacy PIM, an Oracle Marketing Cloud implementation or middleware built decades ago by a large client's IT department, we build case by case. That takes extra time in the planning phase but prevents integration debt later. For agencies that sell their own product layer or want to become a marketplace intermediary, we look at a set-up based on our marketplace platform approach; for content-driven commerce, we build from our headless commerce architecture; for the data layer beneath an attribution platform, we work according to our data engineering approach.

An important difference from large SaaS suites: with us, the API credentials, OAuth tokens and data flows belong to the agency or client. We configure and build, but we do not make Appfront indispensable through the tokens. If an agency or client changes supplier, no hidden account keeps running in the background.

From agency audit to go-live in clear steps.

A martech or agency app project for a bureau follows its own rhythm. Five phases that are recognisable for every bureau, whether it concerns a campaign dashboard, an asset library or an attribution platform.

01 · Audit

Agency process mapping

A day in the office with a producer, a client lead and a tech lead. Result: current tool stack mapped out, duplicate tools and gaps highlighted, client routines described.

02 · Design

Scope per discipline

Which flows go into the app per campaign type, which integrations take priority (ads APIs, CRM, DAM, BI), and which flows belong in a later release.

03 · Build

Short sprints, demo every sprint

Every sprint we deliver a working flow that the account team, creatives and the client can test. The first working flow is live after just a few sprints.

04 · Cutover

Pilot with one brand or client

First one brand or one client account, then the next. With each rollout: training for the account team, onboarding material for new staff, and handover to your functional management.

05 · Maintenance

Ongoing adaptation

With every new ads API version, GDPR change, client migration or brand refresh, we adapt the app. Fixed monthly fee, first-line support within the same working day.

Working in a sector that measures and evaluates.

VEA Agency Barometer

"Agencies that consolidate their client communication and project flow into a single proprietary platform report significantly lower overhead per campaign and higher client satisfaction than agencies running on a patchwork of SaaS tools."

Chiefmartec Marketing Technology Landscape

"In a decade, the martech landscape has grown from a few hundred to more than nine thousand tools — a key reason why serious agencies are moving back towards their own orchestration layers on top of a smaller core of SaaS."

DDA Digital Agency Trend Report

"Digital agencies that develop proprietary IP around data and attribution platforms retain their margins in a market where commodity services face ever-greater price pressure."

Answers for the agency considering its own platform.

The questions we most often hear from agency owners, CTOs and managing directors.

Which types of apps and platforms do you build for agencies?
We mainly build campaign management dashboards, asset libraries and DAM environments, client portals for agencies, white-label apps for agency clients, attribution and measurement platforms, content collaboration platforms, production planning apps for production houses, and marketplace environments for agencies that manage freelance or supplier networks. We work with creative and brand agencies, design and digital studios, as well as media, performance and content agencies. For the service layer of a single defined app, see also our page on app development.
What is the difference between martech custom development and a SaaS package?
A SaaS package is built for the average user, which means it rarely fits perfectly with how your agency works or how your client mix is structured. Custom development follows your process, your client portfolio and your KPIs, and is therefore by definition a better match. The downside: custom development requires an initial investment and a clear roadmap. We often recommend a hybrid model — generic functions remain SaaS (email, ticketing, CRM), while the agency-specific layer becomes custom development.
Do we retain ownership of the code and the data?
Yes. We deliver the code in a repository managed by your agency or your client, with OAuth credentials, hosting credentials and database ownership in your name. If you switch suppliers, no hidden account is involved and a successor can continue the project without Appfront. This is a deliberate policy — an agency should not be locked into a tool once it is serious about growing.
How do you handle GDPR, IAB TCF and Consent Mode v2?
We build consent management in as an integral part of the platform, not as a loose pixel. That means integration with Cookiebot, OneTrust or a custom CMP, passing consent signals correctly through to Google Ads, Meta, LinkedIn and TikTok via Consent Mode v2 and their respective CAPI implementations, and making sure audiences and segments only run on data that is legally covered. For data processing agreements and sub-processors, we provide standard templates as a matter of course.
Can you build a white-label app for our clients?
Yes, that is a frequently requested use case. For multi-tenant white-label apps, we build each of the agency's clients as a separate tenant with its own branding, its own domain, its own role setup and its own data isolation within a single codebase. This saves considerable maintenance effort and still lets each client experience the product as a unique customer. For the details of that B2B delivery context, and how we handle client onboarding, client invoicing and SLAs, we often look together at our page on building a B2B app.
How do your attribution and measurement approaches work?
We build a custom layer on top of Google Ads, Meta, LinkedIn, TikTok, Display & Video 360 and the client's own CRM and commerce data. First-party tracking, server-side events via Meta CAPI and server-side Google Tag Manager, and a dedicated warehouse layer in BigQuery or Snowflake. On top of that sits a modelling layer (Markov, Shapley or a custom MMM) and visualisation in Looker, Metabase or a custom front end. The full data architecture relies on our data engineering approach.
What does a martech platform or agency app cost?
A campaign dashboard for a single agency is a different project from a multi-tenant white-label suite serving dozens of client environments, or an attribution platform with its own data layer. We work with a fixed sprint budget and, after the planning phase, give a concrete price for the complete build, including integrations and compliance work. What we often do is start with one clearly defined flow for a single client brand and only broaden once that works.
Can you build AI into content and campaign generation?
Yes, and we do so with attention to the AI Act, brand risk and legal risk. For content generation we use Claude, GPT, Gemini or open-source models, with brand-voice guardrails per client. For visual generation we work with FLUX, Midjourney-style workflows or Stable Diffusion derivatives, with explicit labelling of AI output as the Digital Services Act requires. For automatic tagging and search in asset libraries, we deliver models that run locally or in a European cloud, so that client assets never leave the EU.
Can you build a marketplace layer for our freelancers or producers?
Yes. For agencies that want to manage their own network of freelancers, talent or suppliers, we build a marketplace layer that brings briefs, availability, contracts and invoices together in one place. This is often combined with a payment flow (Mollie, Stripe) and a rating or review layer. The foundations for this come directly from our marketplace platform approach.
