Let’s make things
clear.
Scope, capacity and commitment. Useful answers to help you choose.
Ask us on a video call ↗What is the difference between Studio and Infinity? +
Studio starts with a bespoke website or application, then combines upkeep and improvement credits with a 36-month commitment. Infinity provides recurring capacity for your design, marketing or development requests, with no minimum term. Solo, Duo and Ultimate share the same catalogue, with one, two or three production lanes.
What exactly is Synerium Infinity? +
A digital team by subscription for your ongoing needs. Choose your production capacity, with design, development and marketing included, then submit requests in your client portal. They progress according to your priorities.
How does “unlimited” work? +
Requests and revisions are unlimited within the scope of your plan. Simultaneous capacity is defined: 1 with Solo, 2 with Duo and 3 with Ultimate. One production lane means one task in progress; the next tasks wait their turn. This capacity is shared across your projects and disciplines.
Are design, development and marketing all included? +
Solo, Duo and Ultimate share the same design, development and marketing catalogue. They differ in their number of active production lanes. Advertising spend, third-party tools and out-of-scope services are not included in the subscription.
Compare the plans ↗What budget do I need to get started? +
Infinity starts at 1,990 € excl. VAT per month with Solo, with no minimum term. Cancellation received before renewal takes effect at the end of the paid monthly period, without additional notice. For Studio Website, see Launch. Advertising budgets and third-party tools remain separate.
How do requests and delivery times work? +
Share your needs, materials and required access. The team defines the scope and timeframe in working days, then produces the work when capacity is available. Track progress, give feedback and approve deliverables in the platform. Larger projects are split into stages.
Who owns the deliverables? +
For paid Infinity plans, rights to deliverables transfer after the relevant subscription month is paid in full, subject to the offer terms and third-party licences. Essentiel’s deliverable can be used commercially without a paid subscription. Studio has a separate framework: code is available on request after the first year and ownership transfers at the end of the contract; remaining monthly payments are still due.
Can I change my subscription? +
Yes, under the offer’s terms: change plan, add Infinity capacity, or adjust Studio credits or scope. Budget and transition are agreed before approval. The commitment and cancellation terms remain those of your contract.
Read the terms ↗I do not know which option to choose yet. +
A 30-minute conversation helps clarify your needs, the required disciplines and your budget. You do not need to have chosen a plan beforehand.
