Hierk: A B2B Networking Platform Where Everyone Connects
How Inventiple's engineering team — through partnership with Exiliensoft — delivered the multi-user-type platform architecture, AI discovery engine, real-time video calling, and Brazilian-market launch readiness for a four-persona B2B networking SaaS launching September 2026.
A networking platform that takes "everyone connects" seriously
Hierk's founders saw a structural gap in B2B professional networking: existing platforms (LinkedIn included) treat all professionals as a single user type with one feed, one profile shape, and one set of interactions. In reality, the way a mid-sized company finds vendors is completely different from the way an autonomous worker finds clients, which is completely different from the way an employed professional develops their career.
Hierk was designed from day one around four distinct user types — Empresa (companies), Empresa de Serviço (service-providing businesses), Profissional (employed professionals), and Autônomo (autonomous workers) — each with its own profile shape, feed logic, discovery rules, and interaction patterns. The platform's job is to make the right connections across these types feel inevitable rather than effortful.
Four user types is four products in a trench coat
Most "multi-stakeholder" platforms claim the title but implement it shallowly — same profile fields, same feed algorithm, just a different label. Hierk had to do the opposite: four genuinely different experiences, each optimized for that persona's actual decision-making pattern, while sharing enough infrastructure that the platform was buildable by a small team and discoverable as one network.
Add to that: AI-driven discovery (so connections are surfaced, not just searched), real-time video and signaling (the moment two users want to talk, they can), Brazilian-market Portuguese localization with international expansion headroom built in, and a pre-launch product polish that matches a Series A's brand bar.
Multi-tenant by persona, shared by infrastructure
Through partnership with Exiliensoft, Inventiple's engineers delivered the platform's architectural foundation: a multi-user-type system where each persona has its own profile schema, feed logic, and discovery rules — but shares the underlying graph, messaging, video, and search infrastructure. This avoided the "four codebases in a trench coat" trap while keeping the per-persona experience genuinely tailored.
On top of that, the AI discovery engine — what Hierk calls Descubra IA — surfaces relevant connections across personas based on intent, location, and complementary needs. Real-time video calling and signaling were integrated for direct user-to-user conversations without third-party tools. The map-based SOS feature handles urgent professional needs (e.g., a company needing an autonomous worker on-site immediately).
A pre-launch product that already feels like a Series A
Hierk is on track for its September 2026 public launch in Brazil. The pre-launch site, waitlist, and admin infrastructure are live at hierk.com, and the visual polish is on par with funded SaaS platforms many years older.
The four-persona architecture has held up under design and engineering review without needing rework — which is the single biggest signal that the architectural decisions in week one were right. Adding new persona types, additional languages, or new connection logic is a configuration change, not a re-architecting effort.
The technical foundation of a multi-stakeholder network
Through our partnership with Exiliensoft, Inventiple's engineers delivered these core technical modules — the foundation everything else is built on.
Multi-user-type architecture
Four distinct user personas (Empresa, Empresa de Serviço, Profissional, Autônomo) with persona-specific profile schemas, feed logic, discovery rules, and access controls — all sharing the underlying graph, messaging, and search infrastructure.
Descubra IA — AI discovery engine
Cross-persona discovery that surfaces relevant connections based on intent, location, complementary need, and historical interaction patterns. Goes beyond keyword search; recommends connections users wouldn't have thought to look for.
Real-time video calling
Native WebRTC-based video calling integrated directly into the platform — no third-party tooling, no Zoom redirects. Two users can move from chat to face-to-face in one click, with signaling and TURN/STUN infrastructure architected for Brazilian network conditions.
Aceno em Massa — mass interaction system
A 'mass waving' system that lets users signal interest to dozens of relevant contacts in a single action — without spamming. Rate limiting, intent-scoring, and reciprocity rules built into the architecture to keep the signal-to-noise ratio high.
Map-based SOS feature
Urgent professional needs (a company needing an autonomous worker on-site immediately) route via a geolocation-aware urgency layer that notifies relevant nearby users in real time. Hard guardrails on misuse — SOS isn't a marketing channel.
Persona-aware feed logic
Each persona sees a feed optimized for the decisions they're making. A company sees vendor recommendations and project signals. An autonomous worker sees demand signals and project opportunities. Same infrastructure, four different experiences.
Portuguese-first with i18n headroom
Brazilian Portuguese is the primary language with full international localization architecture built in. Adding English, Spanish, and other markets is a configuration change — the multi-language layer was planned for from day one.
Pre-launch waitlist + admin platform
The live pre-launch site, waitlist capture, persona-segmented onboarding queue, and internal admin platform are all production-deployed and ready for September 2026 public launch.
Built for scale, designed for clarity
Architecture choices that support four user types today and any number of additional personas tomorrow — without rework.
A platform that's ready for launch without rework
The clearest signal of a successful pre-launch engineering build isn't a metric — it's the absence of rework as the product approaches launch. Hierk has held its architectural decisions from kickoff to September 2026 launch readiness without a re-architecting effort, which is the unambiguous signal that the foundations were laid right.
Four personas, one platform. The multi-user-type architecture has supported design and engineering reviews without breaking. Adding a fifth persona type (or moving to international markets where the persona definitions differ) is now a configuration change, not a re-architecting effort.
AI discovery that surfaces, doesn't search. Descubra IA goes beyond keyword matching to surface cross-persona connections based on complementary needs. A company needing a specialized service finds it without knowing the search terms. An autonomous worker discovers projects without browsing.
Real-time native, not third-party. Video calling and signaling are built into the platform rather than redirecting users to Zoom or third-party tools. The seamlessness of going from message to face-to-face is part of the product's identity.
Pre-launch polish at funded-startup quality. The marketing site, waitlist, and pre-launch infrastructure project a Series A polish that's rare in pre-revenue startups. First impressions matter — and Hierk's first impression is one of a product that's already arrived.
