CoderPad is a hiring platform that lets teams evaluate real engineering skill rather than quiz performance. It combines automated pre-screens, realistic coding assessments, live collaborative interviews, AI-assisted evaluation and anti-cheating controls, and integrates with the applicant tracking systems recruiters already use.

Headstarter builds applied AI products that put agents and engineers to work on real problems and judge them on what they ship. It spans offensive-security agent training, model interpretability tooling, AI-assisted coding, and agent-driven hiring for startups.

It combines automated pre-screens, realistic coding assessments, live collaborative interviews, AI-assisted evaluation and anti-cheating controls, and integrates with the applicant tracking systems recruiters already use.
A multi-file IDE with whiteboard, structured scoring, private notes and code playback so interviewers can assess real problem solving rather than puzzle recall.
Automated pre-screens built from practical engineering tasks, with clear scoring that helps recruiters move qualified candidates forward faster.
AI assistants work with code context, prompts are captured, and AI reviewers rank video or code submissions against your own rubric.
Adaptive tests, activity monitoring, real-time alerts and playback reports help detect suspicious behaviour without manual review.

Build realistic networks — web apps, file shares, databases and internal hosts — for training and evaluating offensive-security agents under rules of engagement.
Load any open model, run it offline on your own GPU, inspect which neurons fire per word, then edit and serve the modified model via an OpenAI-compatible API.
Work across repositories, talk to your code by voice, and let agents plan, edit, test and open pull requests from the browser, with every session traced and scored.
Agents search engineers' real work across GitHub and LinkedIn and score candidates against the role, producing a ranked shortlist with evidence.
