Kiodo.dev, an API-first platform for AI visibility, has crossed 100,000 users and is now expanding beyond its home market in Brazil. The company sells structured access to web search, content extraction, and AI answer tracking, competing directly with Profound, Peec, and Otterly.
The core product is a REST API: call aiVisibility.check() with a brand, category, market, and competitor list, and Kiodo returns visibility scores, share of answer, top cited sources, and gap opportunities as JSON. Teams build their own dashboards and workflows on top of it instead of paying for a fixed SaaS UI. Marketing gets AI visibility reports. Engineering integrates through HTTP agents and MCP.
Founder Antonioni Nascimento Oliveira started building software at 14 in Brazil. He later co-founded LYS, a software and media company that partnered with Genial Investimentos and Bybit, before leaving to focus on independent projects. He spent years consulting across software and media and now runs KRX (KRXlabs.com), an engineering entity focused on cybersecurity, data, and AI. He also completed Stanford's Advanced Cybersecurity Program.
Oliveira invests in D2C companies through a separate vehicle, supplying founders with technology infrastructure, backoffice tooling, and growth strategy. He does not operate the businesses directly. The portfolio gives Kiodo a built-in distribution layer that most API startups do not have, with the combined audience across his D2C holdings reaching millions.
AI visibility is a category that barely existed two years ago. As AI-generated answers replace traditional search results, brands are scrambling to understand whether they appear in model responses, which sources get cited, and how competitors rank. Kiodo is one of a handful of companies building the plumbing for that question. Exa.ai, valued at $2.5 billion in its last round, operates in a parallel lane selling search and embeddings APIs, proving the market appetite for developer-first infrastructure in this space.
The 100,000-user milestone reflects organic, product-led growth rather than paid acquisition. Developers in Brazil and Latin America adopted the API early because alternatives were either expensive enterprise platforms or tools that locked data behind dashboards. Kiodo's pricing is per API call, not per seat, and the data comes back as structured JSON teams can store, inspect, and re-rank inside their own systems.
Oliveira also writes at antonioni.cc, a technical blog covering venture capital, B2C economics, cybersecurity, and the intersection of software and data. The writing has drawn attention from operators and investors tracking infrastructure companies emerging outside Silicon Valley.
The expansion plan targets North America and Europe, where demand for AI visibility tooling is accelerating as AI adoption pushes brands to care about their presence inside model-generated answers. Whether Kiodo can sustain its trajectory against well-funded competitors is an open question, but the 100,000 users suggest the API-first approach has product-market fit.
The market for AI visibility is still forming. Kiodo, Profound, Peec, and Otterly are defining the category in real time. The winner will likely be whoever builds the most useful API, not the most complete dashboard.
