How Syd Life AI is turning health data into better quality of life

Lorena Puica had a successful corporate career, but health issues prompted a re-evaluation that led her to launch the AI-enabled wellness monitoring startup Syd Life AI in 2016.

Headquartered in the United Kingdom, with subsidiaries in Japan and the UAE, Syd Life AI measures quality of life and helps both individuals and institutions improve it. The company has been commercially operating since 2022 and is backed by more than a decade of research and development.

“There is no shortage of health data. The hard part is turning it into something a person, or a population, can act on,” Puica told Disrupt Africa.

Puica began her career in strategy consulting and investment banking, where she looked after more than US$200 billion. She holds five degrees across mathematics, finance and economics, and is a CFA charterholder.

“My background has always been deeply rooted in data, research and quantitative analysis,” she said. “My move into entrepreneurship was shaped by my own health challenges. When my health failed, I discovered that much of the evidence that could help me recover already existed, but it was scattered across research and had never been brought together for one person.”

An algorithm for health

She spent three years studying that research, built an algorithm to synthesize it, applied it to her own data, and recovered. She then set two Guinness World Records, running seven marathons on seven continents in seven days.

“That experience made the wider challenge much more tangible. I saw an opportunity to take the analytical skills I had developed throughout my career and apply them to healthcare and life quality, making existing research more useful and actionable for individuals,” Puica said. “The underlying approach remained rooted in data, research, and numbers; what changed was the problem I chose to apply those skills to. Syd is that system, built for everyone.”

At the heart of the platform is Syd’s Life Quality Index, which measures nine dimensions: physical health, emotional health, financial health, purpose, self-awareness, social life, career, brain power, and environment. It analyses more than 2,390 variables per individual. Behind it sits a proprietary 31-billion-parameter Large Quantitative Model, trained on a daily-refreshed corpus of more than 2.7 million peer-reviewed studies and over 14.3 billion person-years of data covering more than 84 risk models.

For individual members, Syd works on their phone as a 24/7 companion, offering personalized, research-backed lifestyle recommendations. Employers, insurers, governments, and partners get an aggregated, anonymized view of where risk is rising, which interventions are likely to have the greatest impact, and the cost and return of acting.

Translating health data

“The gap is translation. Evidence and health data are both abundant. What has been missing is the infrastructure to apply them to a specific person, workforce, or population,” said Puica. “Most AI in health optimizes a single measure, and for a long time health AI meant a chatbot or a wearable. We asked a different question: what does life quality mean for every individual, and how can improvement in it be measured?”

She said consumer mood and sleep apps, employer mental health providers, and population health analytics firms each cover part of the territory, but Syd Life AI works across all three, with every core component built in-house.

“What distinguishes us is the complete cycle: identify where life quality is rising, intervene, then measure whether life quality improved,” she said. “Much of the market stops at prediction, and prediction without intervention is reporting.”

An independent Scientific Advisory Board, chaired by Stanford biomedical informatics pioneer Dr Lawrence Fagan, oversees the company’s work, reviews the evidence base, and signs off on significant model updates before deployment.

Expanding reach

Syd Life AI has now been deployed across 26 countries within roughly three years of launch. Over 12 months, members improve their Life Quality Index by an average of 19 percent, with stress, anxiety and depression down 48 percent on average and productivity up 23 percent.

“The system was validated in a randomized controlled trial across a workforce of 10,000 NHS frontline doctors and nurses,” Puica said. “Participants experienced statistically significant reductions of 16 percent in clinical anxiety, 14 percent in stress and 12 percent in depression, roughly five times the improvement of standard therapy.”

Japan has been a particularly strong market. A government programme in Tokyo’s Shibuya City raised overall life quality by 20.1 percent, while at Takanawa Gateway City, Tokyo’s first smart city district, onboarding completion reached 98 percent against an industry benchmark of 17 percent.

The startup has also already had a taste of the African market. “A global corporate programme ran across 11 countries, including South Africa, and raised overall Life Quality Index scores by 14 percent in three months, against a two per cent threshold the client had set for success,” Puica said. “Across our clients, return on investment ranges from 12 to 25 times, alongside a 15 percent rise in retention and health risk reduced by up to 40 percent.”

Building a global B2B business

Syd Life AI operates a business-to-business and business-to-government model, with employers, health systems, insurers, and governments licensing the platform for their people, and partners offering it under their own brand. Revenue comes from enterprise licensing and strategic partnerships, and the company reached profitability in 2025.

The company was initially funded by Puica, who put in US$2 million of her own capital while the framework was being built. Investors since include the UK Government, the UAE Government’s sovereign wealth fund, and a San Francisco-based VC firm.

The company counts Japan, the US and the UAE as its three anchor markets, but Puica sees clear potential in Africa.

“Africa fits the same model. The continent combines young, mobile-first populations with rising chronic health costs, and health systems under real pressure to act earlier,” she said. “A local partner is what makes entry properly localized there, from the language and the culture to the way trust is earned.”

The challenges of building a global healthcare business

The journey has not been without its challenges.

“Two things were harder than the technology: staying the course while the market caught up, and being taken seriously in countries where nobody knew us,” Puica said. “We were building robust AI for health long before AI was something the market wanted to talk about. There was pressure to ship a simple app that could generate revenue quickly rather than spend years building the foundations. Saying no to that was difficult, but necessary.”

She said trust was the other major hurdle. “Need alone does not open doors in a new market. Japan is the clearest example: there is profound demand, but trust is built slowly. Partnering with Koshida Corporation gave us credibility and reach we could not have built alone. It is the approach I would take into any new region.”

“Being early is a tax you pay in full, up front, for years. You do not budget for the idea; you budget for the wait,” she added.

Puica took part in the Standard Chartered Foundation’s Women in Tech Accelerator last year. The programme, locally implemented by Companies Creating Change (C3) (Dubai, UAE), with support from Village Capital, provided tailored technical assistance, peer learning and a US$5,000 grant.

“What made the biggest difference was the access it opened to Standard Chartered’s leadership and network, and to investors and business leaders at Demo Day,” she said. “The part that stayed with me was the cohort. Every company in it was led by a woman, and the level of innovation in the room was remarkable. You get a network of founders who understand the decisions you are making because they are making them too, and who stay in touch long after the programme ends. I would recommend applying to any founder who would benefit from that.”
