Mahta Bio: How the brand boosted creative efficiency, reduced CAC, and strengthened the consumer journey with synthetic intelligence
About Mahta Bio
Mahta is a Brazilian foodtech that transforms Amazonian superfoods into practical, delicious, and sustainable nutrition products. Its portfolio includes Mahta Coffee, Cashew Plant-Based Milk, and the Superfoods Shake, developed from 12 Amazonian superfoods using regenerative production methods such as agroforestry, syntropic agriculture, and responsible harvesting.
Beyond its social and environmental impact, the company operates with a digital-first DNA, merging science, nutrition, and technology to build end-to-end experiences that support consumers' health journeys.
With over R$19 million in annual revenue and a strong e-commerce and social media presence, Mahta was growing rapidly but facing challenges in communication, consumer education, and performance predictability.
The Challenge
Despite strong digital traction and a powerful purpose-driven appeal, Mahta was operating in a complex landscape:
A highly innovative product in a familiar category, but one still poorly understood by the general public.
Over-reliance on a few winning creatives, making paid media riskier.
Low mobile conversion (1.3%), even with 90% of traffic coming from smartphones.
Difficulty communicating real value — nutritional benefits and Amazonian differentiators.
The need to validate scripts and content narratives earlier, reducing rework and optimizing budget.
A push for greater predictability and scale in content creation, without sacrificing authenticity.
In the words of Giovanni Zapponi, Co-Founder & CGO at Mahta:
"Our challenge was always how to get the message across to the user in a way that would generate interest and understanding of the product."
The core question was clear:
How do you grow with efficiency, creative predictability, and continuous intelligence — without giving up purpose and innovation?
The Solution: Synthetic Personas + Nexus Galaxies Lab
Galaxies deployed its proprietary Synthetic Personas framework, combining qualitative, quantitative data, and behavioral modeling. The project was structured in two phases:
1. Organic Phase — Research and Behavioral Modeling
1,500 respondents across customers and prospects.
Cross-referencing traffic, repurchase, and engagement data.
Validation of four pre-existing real proto-personas from Mahta's customer base:
Carlos (rational biohacker)
Maria Helena (ethical consumer)
Alexandre (high-performance entrepreneur)
Giovana (sustainable creator)
2. Synthetic Phase — Always-On Intelligence in the Nexus Galaxies Lab
Creation of 8 exclusive synthetic personas, validated via DeepEval with >85% accuracy.
Interactive behavioral simulations available 24/7.
Through interaction with these Personas, the team was able to:
• Test narratives, scripts, creatives, CTAs, nutritional claims, and value propositions — before investing in production.
Giovanni sums up the impact:
"We started using Galaxies to validate scripts well before production. Only the ones with the highest performance potential moved forward. In three months, we reduced acquisition costs by 35%."
Results
The adoption of Synthetic Personas transformed Mahta's creative and operational process, generating direct gains in performance, efficiency, and strategy.
35% reduction in CAC within three months
Pre-validation of scripts and creatives reduced rework, media waste, and costly testing.
10x faster creative validation cycle
Scripts and videos that previously took weeks were now tested and optimized in hours.
+27% CTR on creatives pre-validated in Nexus
Personas helped fine-tune language, pacing, claims, and visual storytelling.
Expanded clarity of the value proposition
The solution uncovered comprehension barriers and refined how Mahta communicates its Amazonian, nutritional, and sensory differentiators.
Adoption of a "synthetic frontline" culture
According to Giovanni
"Galaxies gave us a way to be on the frontline every day, without bothering customers. A much more efficient way to test human interactions."
Supporting the Complete Customer Journey
The personas helped calibrate narratives to each consumer's personal goals — wellness, aesthetics, performance, or daily routine — strengthening the experience beyond the product itself.
Impacto Estratégico
The partnership established a new intelligence model for Mahta:
More precise communication, with narratives shaped by real behavior.
Continuous listening, without relying solely on traditional research.
Operational efficiency, with significant reductions in cost, time, and risk.
Applied innovation, strengthening the fusion of nutritional science, technology, and brand.
Giovanni sums it up:
"A successful partnership starts with listening, and Galaxies did that masterfully. The final solution was precise because it considered our deepest pain points and needs."
Conclusion
The collaboration between Mahta and Galaxies exemplifies how synthetic intelligence + real purpose can accelerate growth, amplify impact, and create culturally relevant brands — without sacrificing authenticity, science, or sustainability.
