Fatih Baltacı

Founder and CEO of GurubaseAnkara and San Francisco

For ten years I have turned research into production systems, from computer vision to open-source infrastructure to trustworthy AI. Gurubase1 turns a company’s documents and tools into AI agents that cite every answer, attach a trust score, and decline when the evidence is thin, and it runs fully air-gapped for regulated industries2. Before that I co-founded Ddosify, later Anteon, whose open-source performance tools passed one million Docker pulls3 and 8,500 GitHub stars4.

Work

Gurubase

2024–presentIn market

An AI agent platform for company knowledge. Agents answer from sources such as Confluence, Jira, Zendesk and Google Drive, show the passages they used, score their own confidence and refuse when the context is weak. They can also call APIs and run actions. Customers choose managed cloud in the EU or Türkiye, their own cloud, or a fully air-gapped install with self-hosted models2.

  • GDPR compliant; SOC 2 audit in progress17.

Siper

2026–presentEarly access

Masks personal data in Turkish text before it reaches a language model, covering 26 categories including the special categories of KVKK, Türkiye’s data protection law. It runs on servers in Istanbul as an API, an OpenAI-compatible gateway or an MCP server. The masking model was fine-tuned for Turkish18.

  • On a public benchmark of 403 human-verified Turkish documents it found 88.1% of personal data, against 72.2% for the best of 15 alternatives19.

Anteon, formerly Ddosify

2021–2024Open source

Kubernetes monitoring and performance testing. It began as Ddosify, a load-testing engine written in Go, and grew into a platform that uses eBPF to map traffic between services without code changes. It gathered 2,443 GitHub stars in its first month20, and I am its largest contributor by commits21.

  • Ranked 20th among the new developer tools of 2022 by StackShare22 and listed in the CNCF Cloud Native Landscape23.
  • Insider’s engineering team chose it over JMeter, Locust, k6 and Gatling for performance testing24.
  • Red Hat published an architecture for latency-driven orchestration built on its latency API25, and Docker featured its desktop extension on the Docker blog26.
8,520stars, Oct 2026Anteon’s GitHub stars, by month20

Alaz

2023–2024Open source

An eBPF agent that watches service-to-service traffic inside Kubernetes clusters without sidecars, code changes or restarts. It has 712 GitHub stars15 and is listed in the eBPF Foundation’s application landscape27.
