Recruitment Infrastructure · Series B–D

Programmable sourcing infrastructure that compresses 47-day pipelines into 14.

Rolero replaces your fragmented sourcing stack with one programmable layer that identifies, contacts, and qualifies candidates across 14 channels — without adding a single sourcer. The result: 94.6% candidate response rate, same headcount, pipelines that fill while your team sleeps.

Trusted by hiring teams at Mercury, Vercel, Cohere, and Algolia to move engineering pipelines at production scale.

Currently routing 38,412 candidate touches/hour across 612 active accounts.

The platform · three engineering pillars

One programmable layer. Fourteen sourcing channels. Zero fragmented tooling.

Rolero is the engineering-grade substrate between your ATS and the open candidate market. You write the rules; we run the routing, dedupe, and qualification at production scale.

  1. 01

    14-channel programmable sourcing layer

    Rolero identifies, contacts, and qualifies candidates across fourteen sourcing channels in a single runtime — so engineering managers stop juggling sequencer windows, inmail credits, and scraping scripts. Compliance controls (SOC 2 Type II, GDPR-DPA, CCPA) apply uniformly across every channel.

    • Email, LinkedIn, GitHub, Stack Overflow, niche forums, and ten more — one API.
    • Channel-specific deliverability tuning baked in.
    • Average response lift vs. manual sequences: +412% within 30 days.
  2. 02

    ATS-agnostic integrations, shipped in one deployment cycle

    First platform to ship native, first-party integrations with Greenhouse, Lever, Workday, and Ashby in a single deployment cycle. Rolero sits behind your ATS of record — never replaces it — and surfaces qualified candidates directly into the recruiter's existing workflow.

    • Bi-directional sync of candidates, stages, and feedback.
    • Average time-to-first-pipeline: 6 days from onboarding.
    • No parallel system of record to maintain.
  3. 03

    Patent-pending candidate deduplication engine

    Multi-threaded outreach creates duplicate-by-design. Rolero's dedupe engine reduces duplicate candidate outreach by 81% across multi-threading workflows — protecting your employer brand, your response rate, and your sourcers from stepping on each other.

    • Identity resolution across channels, aliases, and prior applications.
    • Routing rules prevent the same candidate receiving parallel touches.
    • Auditable dedupe log for every exclusion decision.

We didn't build Rolero to rank candidates. We built it because every Series B–D TA team we spoke to was running the same eleven-tool stack to source engineers — and still losing them to competitors who replied first. The win is operational: one runtime, fourteen channels, no duplicate touches, the same sourcer headcount. Pipelines fill while the team sleeps because the routing, not the humans, is what's running.
