Vital signs from a 30-second face scan.

VastMindz built AI that reads heart rate, HRV, stress and more from a phone camera. We built the apps and the embeddable SDKs that put that technology in users' hands — and when the company was acquired, the work simply continued, directly for the new owner.

Wegile built the consumer apps and the specialized SDKs. Engagement has continued unbroken since 2019, including after the company's acquisition.

The brief

VastMindz had a remarkable AI model — read a person's vitals from a short face scan. What they needed was the engineering to turn that model into products and SDKs the world could actually use.

We built their entire mobile app experience across iOS, Android and React Native — and, crucially, highly specialized SDKs that any B2B partner could plug into their own app to use the vitals technology on an ongoing basis. Contactless vitals (heart rate, HRV, pulse, stress) from the front camera, packaged for real products.

When VastMindz was acquired, our team didn't go anywhere — we began working directly with the new owner and continue at full force today. The work never stopped; only the name on the contract changed.

A camera, 30 seconds, and a full read of your vitals — engineered into apps and SDKs.

The product

The model, made usable everywhere.

No cuff, no wearable. The camera reads six vitals from the user's face, then the app turns them into a reading they can act on — and a trend they can keep.

A live preview, a signal wave, and the six metrics lighting up as each locks in — the wait reads as progress, not lag.

Six vitals, one swipe

Heart rate, respiration, SpO2, HRV, stress index and blood pressure in one carousel — same layout every time, nothing to relearn.

How we worked

Hard AI needs hard engineering around it.

Challenge

A model is not a product

VastMindz had the AI; turning it into reliable apps and reusable SDKs across platforms was the engineering challenge.

Approach

Apps + reusable SDKs

We built native apps and embeddable SDKs so the vitals tech could ship both as consumer apps and inside B2B partners' products.

Result

Continuity through acquisition

The product was strong enough that the acquirer kept the team — we work directly with the new owner today.

The arc

An engagement that outlived an acquisition.

AI that reads heart rate, HRV and stress from a phone camera — we built the apps and the SDKs that ship it. The work continued straight through the company's acquisition.

Why it matters

VastMindz is our strongest continuity story — told without naming names.

A client was acquired, and the work continued straight through, directly for the new owner. When an acquirer does its diligence and keeps your engineering team, that's the highest endorsement there is.

The work never stopped.

Two clients in our history were acquired. With VastMindz, the acquirer became our client — and the engineering carried on without a break. That's continuity you can't fake.
