Trust infrastructure for global trade

Trust is the new trade currency.

SurroundApps builds Provena Trust — the verifiable-trust platform for global trade. We also build infrastructure for supply chains, charitable giving, home healthcare, and the mobile devices people run their lives from.

Issuing EU DPP credentials in Bangladesh apparel for the 2027 regime. Running fertilizer fraud detection across Agro-Tec’s national agro-input network. Verifying field delivery for BRAC’s Ultra Poor Graduation programs. Blockchain chain-of-custody for BPCL recycled-plastic supply chains.

The platform

One verifiable-trust substrate. Four deployment domains.

One platform. One data fabric. One engineering team. The same primitives — verifiable credentials, identity, audit fabric — adapted across industries where the cost of being wrong is too high to absorb.

One platform underneath four deployments: Trade and DPP, NGO field verification, home healthcare, and mobile security
Provena Trust · The primary platform

Provena Trust — where the trust layer meets global trade.

Our industry trust platform. Running in apparel and footwear compliance, trade intelligence, and digital product passports. Bangladesh exporters, US importers and brands, and named deployments across recycled-plastic and agro-input supply chains.

Verifiable credentials for products, supply chains, and the parties moving between them.

Running today in Bangladesh apparel for the EU’s 2027 Digital Product Passport regime, with BPCL for blockchain-verified recycled-plastic chain of custody, and with Agro-Tec for fertilizer fraud detection across a national agro-input network. Now expanding to footwear and regulated goods for US importers and brands under UFLPA and ESPR.

NGO Field Verification

Shohay

Verified delivery and field-worker accountability. The foundation under BRAC’s Ultra Poor Graduation digitalization.

Home Healthcare

Ontor Care

Verified home caregivers, midwives, and nurses for families in Bangladesh. Every shift gated by Face ID, NID identity verification, and a real-time GPS geofence around the patient’s residence.

Provena Trust is built and operated by SurroundApps Inc. — a San Jose and Dhaka-based team with two decades of infrastructure for trust-critical systems.

How we build

Twenty years of building this taught us four things.

Not principles in the abstract. The operating patterns we keep returning to because they are the difference between systems that hold and systems that fail in the field.

i.

Adversarial review before launch.

Every product ships under adversarial review before launch. We design as if the system will be attacked on day one, because the systems we build for — importer compliance, fertilizer authenticity, donor verification — are attacked on day one. Security is the first design constraint, not the audit at the end.

ii.

Field reality over architecture diagrams.

Designs that fail in the village, on shaky 3G, or in a real hospital ward are failed designs — even if they looked good on paper. We test in the conditions our users actually work in, before we test in conditions we designed for.

iii.

Vertical literacy at the engineering level.

Our engineers know how an NGO field supervisor logs a household visit, how a hotel front desk processes a walk-in, how telecom signaling actually behaves under load. The platform is general; the people building it understand the verticals.

iv.

We stay with the consequences.

We stay with clients for years, inheriting the consequences of our own architectural decisions. The discipline of living with what you built is what keeps the next thing you build honest.
