Developer journeys should work when nobody is watching
Apostl helps developer-product teams find and fix the point where a developer or AI agent stops making progress. We run public SDK, API, and documentation journeys in clean environments, preserve the evidence, and turn the failure into a concrete next action.
The company is built around a simple operating belief: a plausible guide, a green build, or an HTTP 200 is not proof that a new user reached a working result.
What counts as evidence in an Apostl developer-journey test?
Apostl treats a developer journey as verified only when the defined terminal outcome is observed in the stated environment. A run begins with one bounded public SDK, API, quickstart, or documentation task and records the environment, commands, responses, elapsed steps, blockers, and acceptance criteria needed to review the result. Static syntax checks remain labeled as static evidence; successful setup or an HTTP 200 does not become runtime proof unless it satisfies the task's stop condition. A blocked journey stays blocked when a credential, external dependency, sandbox resource, or product decision is missing. Reports separate observed behavior from product claims and from analyst inference, and they state what the run did not test. Apostl does not use private credentials, real wallet material, or unsupported assumptions to force a passing result. The developer portal exposes the public contract, while Agent Arena shows how dated benchmark outcomes and frictions are presented for review.
What Apostl does
Apostl works with Web3, fintech, payment infrastructure, and developer-platform teams whose activation depends on a technical integration. The product and services cover agent-readiness audits, continuous developer-journey validation, evidence reports, Agent Arena benchmarks, and privacy-bounded analytics for public AI agent traffic.
The work begins with one bounded journey and one observable outcome. Apostl records the environment, commands, responses, blockers, and acceptance criteria needed to reproduce the result. Private credentials, real wallet material, and unsupported claims are not used to force a passing report.
Evidence before opinions
We separate what was observed from what was claimed or inferred. A static syntax check is labeled as static evidence. A runtime result is labeled with the environment and outcome that actually ran. A blocked journey remains blocked until the missing credential, external dependency, or product decision is resolved.
That standard is designed for AI agents as well as people. Agents need predictable URLs, machine-readable contracts, structured errors, and unambiguous terminal states. Apostl publishes its own OpenAPI file, Markdown pages, llms.txt, sitemap, and public developer portal so its interface can be inspected the same way.
The founders
Apostl is led by Roman Krutovyi and Vladimir Alefman. Their work combines developer ecosystem growth, product positioning, automation, SDK and documentation operations, and hands-on activation programs. The public team profiles and professional links are available on the Apostl homepage.
The company operates as a remote team and works with developer-infrastructure organizations across markets. For commercial, technical, or partnership questions, use the contact page. Apostl does not publish a postal office or telephone number until those details are approved as official company contact information.
