Getproven provides a Vendor Relationship Management (VRM) platform connecting venture capital firms, portfolio companies, and vetted B2B service providers. Elementica joined post-MVP to re-architect the live system for enterprise multi-tenancy, executing a zero-downtime, zero-data-loss migration that expanded platform adoption across 70% of Silicon Valley's premier VC brands.
Product Development/SaaS
Zero-downtime migration — 100% data retention during live multi-tenant database re-architecture
Client context
Venture capital funds invest in hundreds of portfolio startups that independently evaluate B2B vendors (cloud infrastructure, legal, accounting, recruitment). Getproven created a centralized network allowing VCs and founders to share trusted vendor recommendations and verified performance histories, replacing word-of-mouth vetting with actionable network data.
The challenge
Getproven's early MVP was built as a single-tenant system. As top Silicon Valley VC firms began adopting the software, each fund demanded strict tenant data isolation, customized vendor verification logic, and isolated portfolio directories. Converting an active production platform — relied upon daily by top investors — into a secure multi-tenant system without taking the service offline was the central engineering mandate.
Elementica's role
Elementica served as the core product development partner post-MVP. We designed the multi-tenant database architecture, executed the zero-downtime data migration, rebuilt the web interface in Angular 9, and refined the vendor trust algorithms.
The solution
Zero-Downtime Multi-Tenant Migration Engine
We re-engineered the PostgreSQL database schema to enforce logical multi-tenancy using tenant-aware access control middleware. To avoid interrupting live VC operations, we executed a phased migration script that transferred legacy records into isolated tenant spaces in the background while keeping data completely synchronized across active sessions.
Angular 9 Enterprise Frontend Rebuild
We transitioned the frontend to a modular Angular 9 framework. This architecture dynamically renders custom tenant workflows, fund-specific vendor rankings, and permission-gated administrative portals depending on whether the active user is a VC partner, portfolio founder, or B2B vendor.
Algorithmic Trust & Verification Pipeline
We upgraded the platform's core verification algorithms. By combining historical rating data from portfolio founders with enriched firmographic data from Clearbit and Leadfeeder APIs, the system automatically calculates objective vendor trust scores, enabling new portfolio companies to make informed procurement decisions instantly.
Engineering decisions that mattered
Phased shadow-writing migration over a cutover maintenance window
Because Tier-1 VC firms run global operations across multiple time zones, a maintenance window was not an option. We implemented a dual-write pipeline that wrote incoming data to both legacy tables and new multi-tenant schemas simultaneously. Once data parity was verified, we flipped read traffic to the multi-tenant schema with zero service interruption.
Elasticsearch tenant-level index partitioning
To keep vendor searches fast across 5,500+ organizations while respecting tenant boundaries, we partitioned Elasticsearch indices by tenant ID. This prevented cross-tenant data leakage while delivering sub-millisecond search query results.
Results
Getproven successfully scaled into the premier VRM platform for venture capital, onboarding 70% of Silicon Valley's Tier-1 VC funds and reducing vendor selection times by 83% across a network of over 5,500 organizations.
Product evolution
The Getproven platform continues to expand its vendor intelligence capabilities, integrating automated contract repository tools and expense-tracking insights for venture funds.
