FAQs: on science

1. what is the science behind sofi?

sofi is built from a team of seasoned entrepreneurs and scientists with a history of multiple start-ups in health technology, data, life sciences, and biochemistry.

Combining expertise from all the the world, there is no corner of sofi that hasn’t been approached and developed using a scientific lens (well…except maybe the cute plant characters you’ll find for each of our formulation in the app - really, there’s no science there, just love!)

For our plants:

We reviewed hundreds of papers to select the best plants known for their scientific + therapeutic potential to naturally improve sleep and calm, and work closely with herbalists, conservationists and botanic gardens to ensure the quality and sustainability of all our plants.

At our labs, we employ a series of highly technical tests that we use to fingerprint every batch (harvest) of our plant extracts - a process known as chemical fingerprinting. This allows us to understand the precise ratio of active compounds within each of our formulations, as well as the inter-variability between harvests, in turn, explaining our understanding of the precise physiological relationship between people and plants.

To access our white papers on plants and sleeplessness/anxiety (developed for internal use) you can click here, and to learn more about our 3rd-party formulation testing click here.

For our sofi pods:

Developed and refined over a series of different generations - each significantly improving on the one before - our sofi pods are designed with built-in Bluetooth connection which allows us to capture time-series data: the information sofi uses to determine which formulations may - or may not - be working for you.

The pod automatically recognises the contents of each plant capsule, once inserted, and communicates all spraying activity with the sofi app.

sofi then analyses the information collected via your pod by constructing mathematical models that describe the relationship between your sleep and mood and updates this with each and every press. sofi communicates your individual results, directly via your sofi app, once the model certainly reaches over 90-95%.

For our app:

The app combines implicit data and explicit data to create a picture of each of us at the unique level of N-of-1.. Rather than using standard methods of questionnaires, we created signature journaling interactions such as our sofi mood “bubbles,” and journals for calm and sleep, which have been developed and refined by our in-house behavioural psychologist and UX experts over time.

This means that sofi has the ability to journal a plurality of states at the same time, many times, without always asking direct questions. This is much richer than standardised sleep and mood questionnaires, which ask individuals to convert a complex sentiment, like how anxious they were over the last two weeks, to a numeric value between x and y - and to repeat that across many variables.
