Accelerating UX Feedback with Weekly Testing During Product Sprints Using Syntheo

The Challenge: Fast UX Cycles, Limited Time for User Feedback
A global fintech startup developing a personal finance management app faced a classic product development dilemma: how to maintain weekly sprint cycles while continuously validating UX decisions with end users.

Traditional UX research methods—recruiting users, scheduling interviews, running usability tests—were too slow and costly. Moreover, the team wanted early feedback on concepts and micro-interactions, not just final features. They needed reliable user input within 48 hours, every sprint.

The challenge was clear:

• Accelerate testing cadence
• Reduce recruitment delays
• Maintain user realism and data reliability
• Align insights with sprint velocity

The Solution: Weekly UX Testing Using Syntheo To solve the time bottleneck without compromising insight quality, the team adopted Syntheo—DataDiggers’ AI-powered platform for synthetic persona-based insights.

What Syntheo Delivered
Syntheo provided a fast, scalable way to simulate authentic user responses through realistic, AI-modeled digital personas based on historical behavioral data, psychographics, and UX preferences.

Every week, the product team tested:

• New prototypes (via screenshots or embedded flows)
• Task-based usability challenges
• Preference-based decisions (color schemes, microcopy, layout options)
• Emotional response questions (e.g., “How would this experience make you feel?”)

Syntheo’s AI models generated persona-driven reactions in under 24 hours—accurately mirroring likely user behaviors and opinions across different audience segments (e.g., Gen Z budgeters, millennial freelancers, Gen X parents).

The Impact: Insights at the Speed of Sprints
By integrating Syntheo into their weekly sprint rituals, the fintech team transformed their entire product development rhythm:

Key Performance Improvements:

Key Wins:

• Agile alignment: UX feedback was always available by sprint review day.
• Budget efficiency: Reduced spend by 75% on user testing.
• Better prioritization: Realistic synthetic feedback highlighted user frustrations before developers coded solutions.
• Increased stakeholder confidence: Weekly insights built a data-driven culture of iteration.

Why Syntheo Was the Right Fit
Unlike simple heuristics or persona templates, Syntheo builds high-integrity digital personas using real-world datasets and machine learning. That’s what gave this fintech startup the confidence to make critical design decisions without waiting for traditional testing windows.

Additionally, DataDiggers’ commitment to data quality, GDPR compliance, and transparency reinforced stakeholder trust—even when using synthetic data. Syntheo is part of a broader ecosystem that includes Correlix for data augmentation, Modeliq for scenario testing, and Brainactive for traditional respondent-based surveys.

This blended approach meant the team could triangulate insights, verifying critical design shifts with both synthetic and real-world audiences when needed.

What the Client Said

“We never imagined that synthetic users could feel this real. We now build with weekly confidence—every design choice is backed by consistent, persona-driven feedback, all within our sprint cycle.”
— Lead Product Manager, Fintech Client
