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.

Game theory + LLMs to find fair agreements both parties will actually accept

Mediator.ai applies Nash bargaining theory — the mathematical framework for finding equilibrium agreements in cooperative games — combined with modern LLMs to systematize conflict resolution. Rather than acting as a chatbot that facilitates conversation, it treats negotiation as a computational problem: given two parties' stated preferences and constraints, find the agreement surface where both parties are better off than walking away. The system can surface solutions neither party had considered by exploring the full solution space rather than iterating on each party's opening positions. It launched as a Show HN post today and is framed around turning "fairness" from a contested judgment call into a solvable optimization problem backed by decades of cooperative game theory research. This sits at an unusual intersection: serious academic economics (Nash's bargaining solution has a Nobel Prize attached to it) applied to an LLM product. Most AI "negotiation" tools are just chatbots with extra prompting. Mediator.ai's game-theoretic foundation means outcomes have mathematical guarantees about their fairness properties — a meaningful differentiator for high-stakes disputes where trust in the process matters.
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.”
“Most 'AI negotiation' tools are just chatbots with system prompts. Nash bargaining gives this a real theoretical foundation — the Pareto-optimal solutions it finds have mathematical properties that pure LLM approaches can't claim. The Show HN reception was warm, which suggests the concept resonates beyond academic circles.”
“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.”
“Nash bargaining assumes rational actors with well-defined utility functions — neither of which describes most real disputes. When someone is going through a divorce or a contentious business breakup, emotions and power dynamics matter more than Pareto optimality. The theory is sound; applying it to messy human conflicts is a much harder problem than the landing page suggests.”
“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.”
“Commercial mediation and arbitration is a $300B+ industry that runs almost entirely on expensive human experts with inconsistent results. If Mediator.ai can formalize even a fraction of routine commercial disputes — contract disagreements, partnership splits, SLA negotiations — the market opportunity is enormous. The Nash foundation means you can audit the reasoning.”
“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.”
“For freelancers and creators navigating contract disputes with clients, having a tool that can propose mathematically fair solutions — rather than just validating your position — could actually help resolve conflicts faster. The game-theoretic framing makes it feel less adversarial than a lawyer's brief.”
