SaaS development services

SaaS Product Strategy

Strategic Definition
We model your business through a series of workshops using tools like Lean Canvas and Value Proposition Canvas. Together, we define your target audience, value proposition, and prioritise features to create a product roadmap. We also establish key performance indicators (KPIs) to measure progress and success.
‍
Product Validation
We validate your solution by testing your value proposition on a landing page, helping you secure your first customers through a waitlist. This approach allows us to validate solution-market fit and gather direct feedback from the market.

SaaS UX/UI Design

User Journey Definition
We dive deep to gain a core understanding of the value you aim to provide. We then define user journeys that enable this value to be delivered seamlessly.
‍
UX Wireframes
We create low-fidelity wireframes to define the interaction and functionality of the application, without being distracted by its look and feel. This low-fidelity set of wireframes allows us to iterate quickly to reach the desired solution.
‍
UI Mockups
Once we're satisfied with the wireframes, we apply the brand style to make the interface visually appealing and easy to use. We also design different states and interstitial pages to ensure it is ready for development.
‍
Clickable Prototypes
If needed, we create clickable prototypes that allow us to demo the product to potential users or investors.

SaaS MVP Development

Agile Scrum Methodology
We use Agile Scrum methodology to develop in 1-2 week Sprints, within each Sprint, we will prioritise with the business, plan with our developers, and review the results - aiming to release to Production every Sprint once the application is live.

Quality Assurance
Our testers create test cases and scripts based on the defined requirements. Tests are conducted before every release to catch bugs and improve the overall quality of our output.

Data Analytics and Behavioral Science

‍Performance Measurement
We implement data analytics to monitor performance, review data, and develop experiments that test and improve your application.

Behavioural Science Integration
We incorporate behavioural science models focused on habit formation to enhance user engagement.

Viral Loops and Network Effects
We plan to build in viral loops and network effects to boost adoption, increase valuation, and strengthen defensibility.

Different strategies like subscriptions, in-app purchases, and tiered pricing models are critical to optimising revenue streams and catering to diverse user segments.
