Project Overview

Solicy teamed up with Passbase (now Parallel Markets), a Berlin-based fintech company, for digital onboarding software and financial compliance platform development. Within 3 months, 3 Solicy engineers coded a solution that allowed banks, funds, and institutions to conduct KYC and KYB verifications, manage investor accreditation, and adhere to regulations efficiently and securely. The platform was made to explain complex processes, eradicate delays, and offer an effortless experience for individuals and entities alike.

The Challenges

The work entailed solving a multitude of intricate problems. Passbase required different verification workflows supporting individuals and entities with different document needs and approval processes, with one seamless, unified user experience. Investor passport functionality required real-time identity updates, which in turn required instant status updates on partners without page reloads. Fintech compliance level was also difficult, since KYC, KYB, and Rule 506c screenings required strict rule compliance, collection of evidence, and audit trails without slowing down the process. Finally, since the system was processing sensitive PII data, strict data privacy and security controls in the form of encryption, least privilege access, and logging in high detail were necessary.

Multiple verification workflows

We designed separate paths for individuals and entities with different documents and approvals, while keeping one clear UX. Conditional steps and role-based screens handled edge cases without confusion.

Secure identity verification software development

Investor passport features needed live status changes across partners without page reloads. We pushed updates instantly while securing sensitive data and keeping performance strong.

Compliance platform software development

KYC, KYB, and Rule 506c require strict checks, proofs, and full audit trails. We encoded rules without turning the flow into a long manual process.

Data privacy and security

The system handled PII, so we enforced least privilege access, encryption, and detailed logs, while still letting teams work fast.

Our solution

To address these needs, Solicy built a flexible digital onboarding software with conditional workflows and role-based screens, enabling tailored experiences for both individuals and entities. A real-time identity verification software was implemented using live data streams, allowing investor status changes to sync instantly across partner systems while safeguarding sensitive information. Compliance was embedded directly into the workflows, automating checks, capturing proofs, and generating full audit trails to meet regulatory demands efficiently. To secure personal and institutional data, Solicy enforced strong encryption, granular access controls, and robust logging—ensuring both financial compliance and high performance.

Modular flow engine

We built a schema-driven step engine with reusable components and role-based pages, so each path could change without breaking others, and new flows could be added quickly.

    Live updates with WebSockets

    We pushed profile status, document review, and accreditation results in real time, which removed refreshes and reduced support tickets.

      Guided compliance screens

      Clear step-by-step forms, inline validation, document scanning, and checklists helped people submit correct data the first time and lowered rejection rates.
