## Jack and Jill

Jack and Jill reframes hiring as a matching problem solved by AI agents on both sides of the market. For candidates, Jack scans large volumes of job listings daily to surface roles that fit a person's actual goals rather than keyword overlap, and it coaches on career clarity, mock interviews and salary negotiation. For companies, Jill automates candidate sourcing and screening, surfacing people who might otherwise be missed. The two agents coordinate, and when mutual interest exists they introduce the parties directly, skipping the usual application stage.

The platform is designed to sit lightly on top of existing workflows. Hiring teams can reach candidates through the usual channels including Slack and email, connect Jill to their applicant tracking system, and use public profile search to widen reach. Candidates get a conversational experience: they talk to Jack, receive matched roles and early interview feedback with notes on answer quality and what to improve.

The economics are unusual for recruiting: Jack is free for job seekers, and the company pays only when a hire actually happens, so the incentive aligns with outcomes rather than subscriptions. Because features, coverage and pricing terms evolve, check the official site for the current details.

**Pricing & Plans:** Free for candidates. Companies pay, structured around successful hires rather than seat subscriptions. Specific terms are confirmed through contact with the Jack and Jill team, so check the official pricing page for the current model.

- **Jack, the AI career agent:** Scans millions of jobs daily to surface roles matched to a candidate's goals, not just keywords, and guides career decisions.
- **Jill, the AI hiring agent:** Automates candidate sourcing and screening for hiring teams, surfacing relevant profiles from public sources and networks.
- **Direct introductions:** When there is mutual fit, Jack and Jill introduce candidate and company directly, bypassing the traditional application pile.
- **Interview and negotiation coaching:** Jack runs mock interviews with feedback on answer quality and helps candidates understand their value and negotiate offers.
- **Workflow integrations:** Hiring teams can connect Jill to ATS and reach candidates via Slack, email and other existing channels.

**Strengths:** Free for candidates, with the company paying on successful hires; Agents on both sides of the market improve match quality; Direct introductions skip the traditional application pile; Includes interview prep, salary negotiation and biosignals on answer quality

**Limitations:** Value depends on having strong coverage in your industry and region; Company-side pricing is not openly published and requires contact; Direct-introduction model means fewer but more curated opportunities rather than many applications

## StackRef

StackRef is an independent consulting practice run by Keith McDuffee, a CISSP-certified cloud architect with more than 20 years across infrastructure, DevOps, and security, currently also a Senior Director of DevOps and Application Security. The consulting side provides hands-on help designing, securing, and optimizing cloud environments on AWS, GCP, and Azure, with an emphasis on being precise and clear about requirements rather than over-charging or over-complicating.

Alongside consulting, StackRef offers its own designed, self-hosted, end-to-end internal hackathon manager. This product supports the hackathon lifecycle with features such as sandbox environments, AI-assisted scoring, and team collaboration, making it useful for organizations that want to run internal innovation events on their own infrastructure rather than a third-party SaaS.

Being based near Boston and working remotely with clients worldwide, StackRef fits teams that want a senior, accountable expert plus a purpose-built internal hackathon tool. Pricing is arranged through a free intro call or direct email.

**Pricing & Plans:** StackRef does not publish fixed prices. Its model is contact for pricing: you book a free 30-minute intro call or email directly to discuss consulting scope or the self-hosted hackathon platform and receive a quote.
