Capsula Digital products that prove themselves.
Precise scoping, readable design, solid code. Web platforms, SaaS, AI agents and automations — every deliverable ships with its metrics.
Capsula is a B2B product studio based in Paris. We design and ship websites, SaaS platforms, supervised AI agents and business automation. Every deliverable comes with its acceptance criteria and its indicators: WCAG 2.2 AA accessibility, measured performance, security built in from the design stage.

The real blocker
A digital project fails when nobody knows what to measure.
- Pretty pages without clear journeys: few qualified requests.
- A SaaS delivered without onboarding: weak activation, overloaded support.
- Improvised automations: promised gains, unmeasured gains.
- An inaccessible site: legal risk, lost customers, damaged brand trust.
- Late SEO: constant redesigns, unstable traffic.
Expertise
Build what matters: the right lever at the right time.
Conversion-oriented sites and landing pages
Fast, readable pages designed to convince: promise, proof, cases, FAQ and CTA.
Custom web and SaaS platforms
Architecture, interface, roles and key modules: robust, scalable and measurable.
Operational automation
Reliable and maintainable workflows: fewer manual tasks, fewer errors.
Useful assistants and agents
From useful assistants to agents able to execute controlled actions.
Accessibility & compliance
Accessibility built in from design: inclusive experience and reduced risk.
SEO & authority content
Structure your visibility: pillar pages, FAQ, internal linking and useful content.
Approach
A product team, not a page factory.
We work as an integrated team: strategy, UX, development, performance and compliance. Every decision must be explainable, testable and connected to impact.
Two ways to deliver
Page factory
- Mockups without journeys
- Delivery without measurement
- Accessibility as an option
- Support ends at go-live
Product team
- Traceable decisions
- Indicators defined upfront
- WCAG 2.2 AA built in
- Follow-up after go-live
Method
Scope, build, measure, improve.
Each step produces a concrete deliverable. You know what is moving forward, what still needs a decision and why each choice exists.
Scoping (1-2 weeks)
Goals, users, constraints and priorities. Deliverables: prioritized backlog, KPIs and delivery plan.
UX & journeys
Key journeys, content, proof points and prototypes. We validate the substance before the build.
Build & integrations
Development, integrations, automations and instrumentation. Iterative releases.
QA & compliance
Testing, performance, accessibility and security. We reduce debt before go-live.
Go-live & optimization
Tracking, funnels and iterations. We measure, learn and improve.
