About Searchplex

About Searchplex

We design, build, and improve AI search and retrieval systems, balancing relevance, scale, cost, and reliability in production.

Who we are

Focused on search and retrieval engineering.

Meet the team below ↓

Searchplex is a specialist search and retrieval engineering firm founded in the Netherlands and built as a distributed team of senior practitioners.

We bring together people who have designed, built, tuned, and scaled production search systems across legal technology, publishing, enterprise platforms, research, and e-commerce. Our background spans the full retrieval stack: indexing, ranking, relevance tuning, data modeling, infrastructure, and AI-native retrieval.

We are deliberately focused. Searchplex is not a general software consultancy and not a staffing platform. We work on the part that matters most: the retrieval architecture underneath high-stakes search, recommendation, and RAG systems — where precision, scale, and reliability are not optional.

Why Searchplex exists

The ceiling is usually the architecture.

Across industries, we kept seeing the same pattern: capable teams working hard inside systems that were never designed for today's retrieval problems.

Legacy keyword stacks stretched beyond their limits. Vector search added as a bolt-on. RAG layered on top without enough grounding, control, or evaluation. Agentic systems built on foundations that could not support them in production.

The result is predictable: relevance plateaus, costs increase, and systems become harder to reason about as they grow.

Searchplex exists to address that constraint at its root—the retrieval layer. By redesigning the underlying architecture, we help teams move past incremental fixes and build systems that perform reliably in production.

Built around retrieval

Built around retrieval.

The areas where we consistently help teams design, migrate, and improve production systems.

AI Search

Designing search systems that combine lexical, semantic, and behavioral signals into results users can actually trust.

Retrieval Systems

Retrieval systems span candidate generation, ranking, filtering, and relevance—everything that determines what users actually see.

Relevance Tuning

Improving search quality through query analysis, field design, ranking logic, evaluation, and continuous iteration in production.

Search Modernization

Helping teams move beyond legacy stacks, fragmented pipelines, and brittle bolt-ons toward cleaner retrieval architecture.
Community & resources

Sharing production search work with the community.

Searchplex contributes to the search and retrieval community through talks, panels, and technical sessions at events such as Berlin Buzzwords, London Information Retrieval & AI Meetup, and Vespa.ai Live.
