‍

1. Alex – Agentic Recruiting Platform

Best For: Scaling Interview Capacity During Hypergrowth

When your hiring plan scales from 20 to 200 engineers, the first bottleneck isn't sourcing: it's interview capacity. Alex connects with Ashby to hand that workload to Interview, the 24/7 Screening Agent, eliminating the need to expand recruiter headcount proportionally.

Candidates consistently describe their experience with Interview as fair and conversational. With a 92% five-star satisfaction rating, candidates report the process feels more like talking with a thoughtful recruiter than a typical screening call. More feedback is available at alex.com/candidates-love.

Verify, the Fraud & Integrity Agent, detects AI-generated, pre-scripted, or externally assisted responses. It confirms identity using multiple verification signals and flags IP/location mismatches before any developer time is wasted on unqualified candidates.

Connect, the Agentic Automation Hub, orchestrates bi-directional API sync with Ashby. Move a candidate to "Technical Screen" and Connect dispatches Interview; advance or reject in Alex and the Application Tracking System (ATS) updates instantly.

Key capabilities:

• 5,000+ conversational interviews daily, 24/7
• Two-way voice or video with adaptive follow-up questions
• 26+ language support; 48% of interviews after business hours
• 100-point evaluation scoring
• Real-time fraud detection: AI-generated response detection, identity verification, IP/location flagging
• Native bi-directional Ashby API sync via Connect

Integration specifics: Bi-directional REST API with webhook triggers. Implementation typically completes in 24-48 hours.

• Compensation data embedded in Ashby offer flow
• Industry standard comparisons for competitive positioning

Integration specifics: Secure embed within Ashby's offer workflow.

Best For: Series B+ companies formalizing compensation structures.

Pricing: Subscription-based, scales with company size.

Limitation: Doesn't automate offer approval workflows; still requires hiring manager sign-off.

Match Your Integration Stack to Your Funding Stage

When you're scaling through funding rounds, complexity should match organizational needs.

Series A (10-50 employees): A minimal stack: Ashby for tracking, Alex for interview capacity, and Google Workspace for calendar sync covers 90% of daily recruiting work without consuming engineering cycles.

Series B (50-200 employees): Slack, LinkedIn, and Checkr integrate through built-in, no-code workflows. Interview volume increases, making Alex's 24/7 capacity critical for maintaining velocity.

Series C (200+ employees): Add Workday for HRIS handoff and Rippling for automated onboarding. Both run bi-directional syncs, flowing new-hire data into payroll, IT provisioning, and compliance workflows.

Apply this filter: does the integration remove manual work today and scale with future governance needs? If yes, implement it. If not, save it for next round.

API-First Integration: What Tech Teams Need to Know

Ashby's modern REST API and optional GraphQL endpoints handle data flow complexity. The platform fires outbound webhooks on key events like application.stage.changed or offer.accepted, so your systems stay synchronized without polling.

Authentication works two ways: scoped API keys for internal tools, or OAuth when partners need per-user consent. A sandbox workspace lets your team test calls and webhooks before touching production data.

Implementation follows a predictable path:

1. Introduction Call
2. Agreement & Access (API key, scopes, sandbox)
3. Build (endpoints, webhooks, field mapping)
4. Validation & Testing
5. Marketplace Go-Live

Map custom fields explicitly and store Ashby's immutable IDs to maintain referential integrity. Native click-to-connect setups typically go live within 24–48 hours; net-new connections usually ship in one to two weeks.

Scale Tech Hiring Without Scaling Recruiting Headcount

You're under pressure to double headcount, but budgets rarely stretch to double your recruiting team. Alex changes that math entirely.

Interview conducts more than 5,000 structured conversations daily, with 48% after business hours. Verify ensures every candidate is authentic through real-time fraud detection. Discover surfaces qualified candidates already in your pipeline. Connect orchestrates bi-directional data sync with Ashby.

You scale interviews and decision-making capacity, not payroll. This approach transforms your hiring infrastructure from labor-intensive to intelligence-driven.
