From Idea to Product with a 6 Day Design Sprint
Rated 5/5 by 37+ members
You have a great idea, but now what ?
Before anything yet, we should all start answering these 6 essential questions :
Prioritize your product beyond theory
We help you de-risk your product and move faster with a validated prototype using design thinking to turn your idea into an intuitive, seamless product experience.
Design sprints
An intensive, hands-on collaboration
Full-time engagement, 6 to 12 days, repeatable
One Product Designer + one CTO, fully dedicated throughout the sprint
- 4 Design workshops (2h each)
- Technical specifications for your product
- UI/UX Figma prototype
- Fixed price per sprint
- 100% ownership — everything we produce is yours
- Dedicated WhatsApp channel to keep communication flowing during the project
Market validation is the only way to test a product through customer interviews and feedbacks around a clickable prototype.
Design Sprint unveil ideas, assessments and KPIs that design team needs to build great products.
Build, Test, Iterate and then Launch. Design Sprint is about how testing an idea viability without the waste of launching.
What you get
A Design sprint will establish accurate answers to your product value.
Design sprint is the Lean Startup way to reduce risk and is a discovering process on what users want and what you should looking to build.
How do we deliver your product ?
The SAY Digital Design Sprint Framework is at the very foundation of our process.
It is split into 6 main phases of development :
VISION
In this beginning Workshop, we are going to enlighten you on startup culture and the Lean Development methodology. The main goal is to work with you to identify your business problems and opportunities in order to shift an idea to a product.
PROBLEM
Once the problematic of your business has been exposed we should have to focus on customer problem understanding through the creation of users feedback to study your market product impact.
SOLUTION
Having a great problem solver product is great, but we have to leverage a revenue model from it. During this workshop, your SAY Digital Product Manager (PM) will assist you writing a compelling elevator pitch outlining your business model key advantages and extracting a content strategy implementing SEO, UX, digital marketing and launch impact componenent.
PROTOTYPE
During the design sprints, it's all about answering critical business questions through design, blueprint, wireframing, prototyping and customer interviews. The purpose of this workshop is to get you a basic clickable prototype, in order to make your product available for users feedbacks with enough features.
USERS TESTS
The bottom line of this workshop is to expose your prototype to real targeted users according to persona stories outlined in workshop #2. This step is fundamental to get significant data on your product, features and market.
ITERATE
In this last workshop, we are going to use reverse thinking to learn from our results. If your strategy doesn't deliver the anticipated returns, it can be adjusted and refined, both at the prototype and strategic level, through the iterative phases of your product development process.
Frequently Asked Questions
Design Sprint & Prototyping – Everything You Need to Know
Requirements & Specifications
How do you structure the requirements document ?
We structure the requirements document to remove ambiguity and accelerate execution. It includes&:
- Context & objectives – Your vision, success metrics, and KPIs
- Personas & use cases – Who the product is for and how it’s used
- Feature prioritization – MVP vs. nice-to-have, clearly defined
- Technical & brand constraints – Integrations, tools, guidelines
- Timeline & deliverables – Clear steps and milestones
This structure ensures fast alignment and prevents costly misunderstandings before design and development.
Do we need detailed specifications before startingr ?
No. The Design Sprint is specifically designed to clarify your needs and product direction quickly.
If you already have :
- a requirements document
- functional specifications
- or a partially defined idea
We leverage them as a starting point to move faster.
If not, that’s fine too. Our process works even with a rough vision. Through workshops, we help you identify what really matters and turn assumptions into clear decisions.
That said, having at least :
- one clear primary objective
- a defined target audience
- major constraints (budget, timeline, tech)
...will significantly increase speed and impact.
UX Thinking & Design Strategy
How do you approach the UX thinking phase ?
UX strategy is where we de-risk your product. We focus on understanding users and business goals before designing anything. This includes :
- understanding user needs, expectations, and pain points
- defining clear user journeys
- structuring information architecture
- prioritizing features based on value
- validating decisions through user testing (if included)
To do this, we rely on :
- User research – Interviews and behavioral insights
- Empathy mapping – What users actually care about
- Competitive benchmarking – What works (and what doesn’t)
- Jobs to Be Done – The real problems your product solves
All design decisions, from wireframes to prototypes, are grounded in this research.
Do you test the UX with real users ?
Yes, if you want to. User testing can be added to validate your product before development. Testing helps to: :
- confirm users understand the flows
- identify friction and usability issues early
- collect actionable feedback before you invest in code
We synthesize results into clear insights and UX recommendations.
Design Sprints can include testing sessions with 5–8 representative users (which you can provide). This allows us to validate or adjust direction quickly and confidently.
Testing early helps avoid expensive mistakes later.
Co-creation Workshops
Do you run co-creation workshops ?
Yes. Co-creation workshops are a core part of our Design Sprint process. They help teams to :
- align product, marketing, and tech stakeholders
- surface the best ideas collaboratively
- make decisions faster
- create strong ownership and buy-in
Workshops can be run remotely or in person in Paris (on request).
How long do the workshops last ?
Workshops typically last 2 to 4 hours and are spread throughout the Design Sprint to maintain momentum without overload.
What happens after a co-creation workshop ?
After each workshop, we turn discussions into concrete outputs, including :
- Specifications & features – A clear requirements document and product backlog
- Wireframes / sketches – Visual direction and structure
- User flows – Detailed end-to-end journeys
- Interactive prototype – Ready for validation and testing
You leave with tangible assets that directly feed the next design or development phase.
Figma Mockups & Prototypes
Do you deliver usable Figma files or only exports ?
We deliver fully editable Figma files, not static exports. They include: :
- Clean, well-organized layers
- Reusable components and optional design system
- Interactive prototypes with micro-interactions
Your team can immediately reuse, modify, and hand them off to developers.
Do you create a design system or just mockups ?
Both. We build scalable design systems, not just screens. This includes: :
- Design tokens (colors, typography, spacing)
- Modular components (buttons, inputs, cards, etc.)
- Reusable patterns
- Developer-friendly documentation
This ensures consistency, scalability, and faster implementation.
Are the Figma prototypes fully interactive ?
Yes. Our prototypes behave like real products :
- Full interactions (clicks, scrolls, transitions)
- Subtle animations and micro-interactions
- States and validations (errors, loading, success)
- Responsive views (mobile, tablet, desktop)
Stakeholders and users can experience the product before it’s built.
Can the prototype be tested with users ?
Yes. User testing can be added to validate the prototype before development. Testing allows you to :
- confirm user understanding
- identify friction points early
- collect concrete feedback with minimal cost
You can provide your own users to keep budgets under control. Results are summarized with clear UX recommendations.
What happens after the Design Sprint ?
At the end of the sprint, you get :
- a functional, testable prototype
- a clear and validated product vision
- documented feature decisions and specifications
- deliverables ready for immediate execution
We can then support you with :
- detailed UI/UX design
- development preparation
- coordination with dev teams
- long-term product evolution
Intellectual Property & Contracts
Who owns the rights to the designs created ?
You own 100% of the output. Our contract includes a full IP transfer, meaning you get :
- exclusive ownership of all design files
- full usage rights, with no limitations
- the ability to modify and adapt freely
- the right to share with partners or developers
- the right to sell or license the work if needed
No hidden clauses. No restrictions.
Are we bound by a confidentiality agreement ?
Yes. Confidentiality is built into our contracts. This includes :
- a mutual NDA to protect sensitive information
- a defined confidentiality period (typically 2–5 years)
- standard legal exceptions where required
- data destruction upon request or contract end
We work discreetly. Protecting your product, your data, and your users is non-negotiable.
