Aperture replaces the keyword-matching stage of hiring with autonomous AI-conducted behavioral interviews and comparative candidate ranking. Rather than filtering resumes by whether they contain the word 'Kubernetes' or 'Series B experience,' Aperture schedules and conducts structured situational interviews with every applicant, evaluates responses against custom rubrics, and ranks candidates against each other — all before a human recruiter sees a single name. The product targets the worst-known failure mode in early-stage hiring: resume screening filters out qualified candidates who describe their experience differently while passing through keyword-stuffers who know how to optimize for ATS systems. Behavioral interviewing surfaces actual competency patterns rather than self-reported credentials. The AI evaluator applies a consistent rubric regardless of which recruiter reads the response, addressing a source of structured bias that's hard to fix with human screeners alone. Launched on Product Hunt today, Aperture enters a crowded but unsolved space. The differentiation is the full-stack approach — conducting the interview autonomously rather than just scoring human-conducted interviews, which compresses the screening timeline from weeks to hours.

Mediator.ai applies LLMs and Nash bargaining theory to real-world disputes, generating agreements that both parties would accept — including solutions neither side had imagined independently. The process is private by design: each party separately describes their position, priorities, and constraints. The AI then generates multiple candidate agreements, scores each one against both parties' stated needs, and iteratively refines proposals until reaching an optimal solution. Use cases range from founder equity disputes and contractor payment conflicts to shared housing arrangements and inheritance disagreements. The system's key insight is that human negotiation is systematically bad at identifying the entire solution space — we anchor on positions, not interests. By modeling both parties' utility functions simultaneously, the AI can find Pareto-optimal outcomes that pure adversarial negotiation often misses entirely. With 159 Hacker News points, the response was genuinely enthusiastic — and the concept is hard to dismiss. Nash bargaining as a formalism has decades of academic credibility; what's new is making it accessible via natural language input. The pricing isn't published yet and the team is small, but the application domain (legal, HR, personal disputes) is enormous if they can nail trust and confidentiality.
Reviewer scorecard
“Running a startup means I'm buried in applications every time I post a job. Having an AI conduct initial behavioral screens means I only see candidates who've already demonstrated they can articulate relevant experience. The comparative ranking is more useful than individual scores — it tells me who's best among the pool, not just who cleared a threshold.”
“Applying Nash bargaining theory via LLMs to real disputes is a genuinely novel use case — not another chatbot wrapper. The architecture (private inputs, joint optimization, iterative refinement) is well-thought-out. I'd use this for contractor disputes before paying $400/hr for a mediator.”
“AI-conducted hiring interviews carry real legal risk — EEOC guidance on automated employment decisions is evolving rapidly, and several states already require human review for consequential hiring choices. The rubric design problem is also unsolved: if the rubric encodes biased assumptions about what 'good' answers look like, the AI will systematically discriminate at scale. I'd want an independent audit before using this for anything above entry-level roles.”
“Real mediation relies on trust, confidentiality, and legal enforceability — none of which Mediator.ai can guarantee. If both parties don't trust the AI, the outcome is worthless. And for anything involving money or legal rights, you still need a human to ratify the agreement. The use case is narrower than it looks.”
“The hiring funnel is one of the last major business processes that still runs primarily on gut instinct and keyword matching. Aperture points toward a world where assessment of actual competency replaces credential signaling — which is a genuinely more meritocratic outcome if the rubrics are well-designed. The regulatory questions are real, but the direction is right.”
“AI mediation is going to quietly eat a massive slice of the legal services industry — not the courtroom drama, but the 90% of conflicts that never get resolved because lawyers cost too much. Mediator.ai is early but points at a multi-billion dollar opportunity in access to justice.”
“As someone who hires freelancers frequently, the promise of getting past 'looks great on paper' to actual capability assessment without scheduling 20 intro calls is compelling. Even if I ultimately talk to everyone, having AI pre-screen with behavioral questions means I'm having better conversations with more prepared candidates.”
“I've lost two client relationships over vague contract disputes that felt unsolvable. A private, AI-mediated negotiation tool that finds solutions neither side saw? Yes please. Even if it only works 60% of the time, that's better than the current outcome of 'both parties ghost each other.'”
