Foundations

Typography

A two-family system: Jost - geometric, near-monoline - for display and headlines, and Osnova Pro, a warmer humanist sans, for body. JetBrains Mono handles data and version strings.

The EVOLVE wordmark is a separate case - drawn in Futura Light. It is not a headline face; never set running headlines in Futura. See Logo & Symbol.

Special usage - the Lecture Series serif

The Evolve Lecture Series graphics introduce one deliberate exception to the two-family system: speaker names are set in a classic high-contrast serif - Times New Roman - which lends the guest billing a poster-like, editorial gravity against the deep-violet canvas. It is reserved only for speaker names on Series collateral; never use it for product UI, body copy or general headlines.

One serif, one job. Everything else on a Series graphic - role, lecture title, body and meta - stays in Jost and Osnova Pro. See the layouts in Brand in Use.

Type scale

Headlines are Jost in sentence case; body is Osnova Pro. The ramp is fluid - sizes below show the desktop end of each clamp.

The eyebrow rhythm

The brand’s signature heading pattern: a small all-caps eyebrow, a sentence-case headline, then body. Repeat it across sections, slides and pages.

Layer 1 - Data

Meaningful data for prediction

Most health data is collected after the fact or in narrow clinical settings. Evolve is built around free-living conditions - measured where life actually happens.
