Build a backchannel reference map for a candidate by identifying the people who genuinely worked with them, the evidence for that relationship, and what each person is best positioned to validate. Unlike traditional reference checks, this starts with the candidate’s professional history—not a list of references they provide. The goal is to identify credible, first-hand sources who can provide meaningful signal about the candidate’s work.

​
When to use it

Use Backchannel References before conducting reference checks when you want independent validation from people who actually worked with the candidate. It is especially useful when:
  • hiring for senior or executive roles;
  • validating a candidate’s responsibilities or impact;
  • understanding leadership, collaboration, or execution style;
  • identifying references beyond those nominated by the candidate;
  • preparing structured reference interviews;
  • checking whether key parts of a career are well supported by credible references.
For example:
Build a backchannel reference map for this candidate. Focus on people who worked with them during their time at Stripe.

​
What you get

The task produces two outputs. reference_map.csv A ranked list of potential references, including:
  • relationship to the candidate;
  • evidence they genuinely worked together;
  • what they are likely able to validate;
  • confidence level;
  • tailored questions for each person.
Summary A concise overview including:
  • recommended outreach order;
  • areas of the candidate’s career with strong coverage;
  • career periods where strong references could not be identified;
  • suggested follow-up searches if important gaps remain.
The goal is quality over quantity. Five strong references with clear overlap are significantly more valuable than a long list of weak connections.

​
How it works

Start by replacing: Candidate CV with either:
  • the candidate’s CV;
  • a resume;
  • a LinkedIn profile;
  • or another document clearly identifying the candidate.
The task first confirms that the correct individual has been identified. If the CV cannot be accessed or public information does not clearly match a single person, it will ask for the CV before continuing rather than making assumptions. Once the candidate has been identified, the task performs broader research beyond the CV, looking for additional public evidence such as:
  • LinkedIn experience;
  • conference talks;
  • published articles;
  • press coverage;
  • project credits;
  • open-source contributions;
  • patents;
  • company announcements;
  • speaking engagements.
This often reveals roles, reporting relationships, or collaborators that are abbreviated or omitted from the CV itself. The task then identifies people with credible evidence that they genuinely overlapped with the candidate before ranking them by likely reference value.

​
How references are prioritized

Not everyone who worked at the same company is an equally useful reference. The task prioritizes people most likely to have first-hand knowledge of the candidate’s work. In general, priority is given to:
  1. Direct managers, founders, executives, or skip-level leaders.
  2. Senior stakeholders who worked closely with the candidate.
  3. Close peers on the same team, product, function, or region.
  4. Cross-functional partners who regularly collaborated with the candidate.
  5. Customers, investors, advisors, board members, or external collaborators where relevant.
Direct reports are generally included only when they provide meaningful evidence about leadership style. People with only weak or uncertain overlap are excluded from the CSV and instead discussed as possible coverage gaps.

​
Understanding the evidence

Every reference should include public evidence supporting the relationship. Examples include:
  • overlapping employment dates;
  • shared team pages;
  • conference presentations;
  • company announcements;
  • product launches;
  • engineering blogs;
  • press releases;
  • public project credits;
  • organizational announcements.
The task clearly separates: Confirmed facts Information directly supported by public evidence. For example:
  • both people worked at the same company during the same period;
  • both appeared on the same product launch;
  • one publicly announced reporting to the other.
Reasonable inferences Relationships that are likely but cannot be directly confirmed. For example:
  • two Product Directors in the same organization likely collaborated;
  • a VP was probably the skip-level manager for a Product Manager;
  • Engineering and Product leaders likely worked together on the same initiative.
Where reporting relationships or collaboration cannot be confirmed publicly, the task explains the uncertainty rather than presenting it as fact.

​
Understanding the CSV

Each row represents one potential reference. The CSV includes: Relationship category How the person most likely worked with the candidate. Overlap context Where and when the relationship appears to have existed. Evidence The public information supporting the overlap. Likely validation areas What this person is probably best positioned to assess. Examples include:
  • technical ability;
  • product judgment;
  • leadership;
  • stakeholder management;
  • customer relationships;
  • hiring ability;
  • execution;
  • communication;
  • ownership.
Confidence Each reference is labeled High or Medium confidence with a short explanation. Confidence reflects the strength of the public evidence for the working relationship—not whether the person would give a positive reference. Tailored questions Questions are customized to the relationship. For example, a direct manager might be asked about prioritization and ownership, while a cross-functional partner might be asked about collaboration and influence.

​
How to improve the input

The best additional context narrows the period or type of reference you care about.

​
Focus on a specific role

Prioritize references from the candidate’s time at Stripe.
Useful when one employer is most relevant to the hiring decision.

​
Focus on a competency

Prioritize people who can speak to executive leadership and organizational scaling.
This changes which references rise to the top.

​
Prioritize certain relationship types

Focus on former managers and senior stakeholders. Ignore peer references unless manager coverage is weak.
Useful when a structured leadership reference is required.

​
Focus on a specific project

Prioritize references connected to the Payments platform migration.
This often produces stronger validation than simply searching by employer.

​
Exclude recent employers

Do not include anyone currently working with the candidate.
Useful when confidentiality is important.

​
Useful ways to adapt the task

​
Leadership hiring

Prioritize former executives, founders, and board members who observed strategic decision-making and organizational leadership.

​
Technical hiring

Prioritize engineering leaders, architects, and technical peers who can validate system design, delivery, and technical judgment.

​
Product hiring

Prioritize engineering, design, GTM, and executive stakeholders who worked closely with the candidate on product launches and prioritization.

​
Sales hiring

Prioritize sales leadership, major customers, partnerships, and cross-functional GTM collaborators.

​
Executive diligence

Focus on the candidate’s most senior roles and look for multiple independent perspectives from leadership, peers, and cross-functional partners.

​
How to interpret the results

A strong reference map contains independent evidence covering most major stages of the candidate’s career. Several high-confidence references from different perspectives are generally more valuable than many references from a single team. Pay particular attention to:
  • whether the strongest references come from the candidate’s most relevant role;
  • whether managers, peers, and stakeholders all appear;
  • whether multiple sources can validate similar strengths;
  • where important career periods have little or no coverage;
  • whether the evidence supports direct collaboration rather than simply overlapping employment.

​
Common pitfalls

Treating company overlap as evidence of collaboration Working at the same company does not necessarily mean two people worked together. Assuming reporting relationships Reporting lines often cannot be confirmed from public information and should not be inferred without supporting evidence. Including weak connections A smaller number of well-supported references is usually more valuable than a long list of uncertain matches. Ignoring older roles Some of the strongest references come from formative roles that receive little attention on a current CV. Confusing confidence with reference quality A High-confidence relationship means the overlap is well supported by public evidence. It does not predict what the person will say about the candidate. Using backchannel references without appropriate consent or compliance Hiring practices vary by company and jurisdiction. Ensure any outreach complies with your organization’s policies, applicable employment laws, and candidate-consent requirements.
  1. Start with the candidate’s CV or LinkedIn profile.
  2. Generate the initial reference map.
  3. Review which career periods have the strongest coverage.
  4. Check whether the highest-priority references match the competencies you want to assess.
  5. Add any role-specific focus or constraints and rerun if needed.
  6. Use the tailored questions to structure reference conversations.
  7. If important career periods remain uncovered, follow the suggested searches to identify additional public evidence or potential references.
The strongest backchannel reference maps combine multiple independent perspectives across a candidate’s career, giving a more balanced picture than relying solely on nominated references.
