Custom influencer marketing software, built around how you work
As influencer programmes grow, they often outgrow spreadsheets, inboxes and shared folders. Finding the right creators, chasing content, approving posts, tracking results and paying people on time becomes slow and error-prone.
We design and develop influencer marketing platforms that solve those problems. That might be an internal campaign management tool for a brand, a client-facing platform for a business that runs creator programmes, or a two-sided marketplace that connects brands with creators.
Every platform is built as bespoke software, so the workflows, data and integrations match your business rather than a generic template.

Custom platform vs ready-made SaaS
Ready-made influencer tools are a good fit for many teams. A custom platform makes sense when they no longer fit how you work.
| Ready-made SaaS tool | Custom-built platform | |
|---|---|---|
| Upfront cost | Low; you pay a subscription | Higher; you invest in a build |
| Ongoing cost | Subscription fees, often rising with users or features | Hosting, third-party services and maintenance |
| Time to start | Days or weeks | Months |
| Flexibility | Limited to the vendor's features and roadmap | Built around your workflows |
| Ownership | You rent the software | You own the code and product |
| Integrations | The vendor's available connectors | Connected to your CRM, finance and data systems |
| Maintenance | Handled by the vendor | Your responsibility, or a support partner's |
| Best when | Standard needs and a quick start | Unique workflows, client portals, marketplaces or a product to sell |

| Social platforms | Instagram (Meta Graph API), TikTok developer APIs, YouTube Data and Analytics APIs | Creators connect their own accounts; available data depends on account type, permissions and app review |
| Payments and payouts | Stripe Connect, PayPal | The payment provider handles onboarding, checks and the movement of funds |
| Contracts | E-signature services such as DocuSign | Signed agreements stored against each campaign |
| Business systems | CRMs, accounting software, email and notification services | Fewer manual updates between systems |
| Tracking | Tracking links, discount codes, ecommerce platforms | Connects campaigns to sales where data allows |
UK compliance considerations
Influencer marketing in the UK is closely regulated. Your platform can make good practice easier, but it can't guarantee compliance on its own. Brands, businesses and creators remain responsible for their campaigns, so we recommend specialist legal advice for your use case.
We design with these requirements in mind from the start:
- Ad disclosure: ASA rules and CMA guidance expect paid content to be clearly labelled, such as with "#ad". Platforms can prompt for disclosure and keep records.
- Consumer protection: the CMA can take direct action against misleading practices, including fake reviews.
- UK GDPR: lawful basis, consent, data minimisation, retention and data-subject requests for creator and user data.
- Social platform terms: data use limited to what each platform's developer terms allow.
- Secure payments: card data and payouts handled by regulated payment providers, not stored on your platform.

Influencer marketing app development FAQs
How much does influencer marketing app development cost?
As a guide, a focused influencer campaign management platform typically starts from £15,000 to £40,000. A business platform with payments, client portals and advanced reporting is typically £40,000 to £120,000, and a full two-sided creator marketplace usually costs £120,000 or more. The final cost depends on features, user roles, integrations and scale, and we provide an itemised GBP quote after discovery.
How long does it take to build an influencer marketing platform?
A focused platform usually takes 3 to 5 months, a business platform with payments and advanced analytics 5 to 9 months, and a full creator marketplace 9 months or more. We deliver in two-week sprints, so you see working features throughout the build.
What features does an influencer marketing platform need?
Most platforms need creator profiles and discovery, campaign creation, briefs, messaging, content review and approval, performance reporting, payments and invoicing, and role-based dashboards for brands, creators and administrators. Features such as AI-assisted matching, client portals and white-labelling can be added as your needs grow.
Can the platform connect to Instagram, TikTok and YouTube?
Yes, through each platform's official APIs, subject to their terms, approval processes and rate limits. Creators typically connect their accounts with their permission, and the data available varies by platform and account type. We don't build tools that scrape social networks or bypass API restrictions.
Should we build a custom platform or use an existing SaaS tool?
An existing SaaS tool is usually faster and cheaper to start with if its features fit your workflow. A custom platform makes more sense when you need your own workflows, integrations, data ownership or a product you can sell to others, such as a marketplace or white-label platform.
How do payments to creators work?
Payments are usually handled through a regulated payment provider such as Stripe Connect or PayPal, which manages onboarding, identity checks and payouts. The platform records campaign milestones and triggers payments or invoices, while the payment provider holds and moves the funds.
Will the platform make our campaigns legally compliant?
Software can support compliance, for example by prompting creators to label content as advertising, keeping approval records and managing consent, but it can't guarantee it. Brands, agencies and creators remain responsible for following ASA and CMA guidance, UK GDPR and platform rules, and we recommend taking legal advice for your specific use case.
Can the platform scale as we grow?
Yes. We design the architecture, database and hosting to handle growth in users, campaigns and data, and plan for higher traffic during busy campaign periods.
Will we own the platform and source code?
Yes. Full ownership of the source code, designs and documentation is transferred to you. Third-party services such as payment providers and social APIs remain subject to their own terms.
Do you provide maintenance after launch?
Yes. We offer ongoing support covering security updates, bug fixes, monitoring, social API changes and new features. Social platforms change their APIs regularly, so ongoing maintenance is important for influencer software.
