The problem

Packaged Recruiting Agents Look Great in the Demo. Then They Meet Your Stack.

A candidate applies at 11:14 PM. The interview invite goes out in a minute. Then the trouble starts.

  1. Break 01 · Data fit

    Your fields do not fit theirs.

    Custom ATS fields, old dispositions, and partial webhooks send screening results to the wrong place, or send them twice.

  2. Break 02 · Ownership

    Nobody owns the whole picture.

    One tool parses, another ranks, a third runs the interview. When legal asks how a decision was made, no single system can answer.

  3. Break 03 · Risk

    You carry the risk they created.

    Hiring AI is classed as high risk under the EU AI Act, and NYC Local Law 144 can require independent bias audits. Employers carry their own obligations, even when a vendor built the tool.

  4. Break 04 · Cost

    You rent what should be yours.

    Your questions, interview data, and scoring logic live in someone else's platform, priced per interview or per seat.

Build or buy

Buy, Orchestrate, Or Build With A Partner: An Honest Comparison

Most teams should look at packaged platforms first. Here is where each path wins, and where it breaks.

Hire comes both ways: buy it as a platform, or use it as the base for a custom build. Need a voice agent beyond hiring? See our AI voice agent development.

When Is Custom the Right Call?

Your ATS or HRIS has custom fields and workflows that packaged connectors do not handle cleanly.

Buy instead if

Your workflows are standard, your volume is low, and you need interviews running this month. We will tell you that on the first call.

    Candidate questions and status

    Answers pay, location, and process questions from approved answers only, and tells applicants where they stand.

Integrations

Your ATS Stays the System of Record

The agent works around your systems, not the other way round.

We map your fields, stages, and dispositions before we write any code. The agent listens for stage changes, writes back with the right IDs, and follows your rules on who can change what.

It can move a candidate to the next round. A person sets the final decision. Sign-in runs through your identity provider, with role-based access and a full log of every read and write.

FAQ

Frequently Asked Questions

Not covered here? Tell us what you run and we will answer on the first call.

What is an AI recruiting agent?v
An AI recruiting agent is software that runs recruiting steps on its own, such as inviting applicants, running a structured screening interview, and booking the next round, while people keep the final hiring decisions.
Why build a custom agent instead of buying a platform?v
Buy if your workflows are standard. Build when your stack, your compliance rules, or your hiring volume make a packaged tool a poor fit, or when you want to own the agent, its questions, and its data.
Will candidates know they are talking to an AI?v
Yes. Every interview opens with a clear disclosure, and candidates can ask for a person at any point.
What if a candidate's camera goes dark or they stop talking?v
The agent gives a warning and can end the interview if needed. It never rejects anyone on its own. Flagged interviews go to a person for review.
Which ATS and HRIS platforms can it work with?v
We connect through your system's own APIs and webhooks. Tell us what you run, and we will map it with you in the scoping call.
How do you handle bias and compliance?v
Structured questions, logged decisions, adverse impact monitoring, and human review of flagged interviews. We design these with your legal team before launch, not after.
What happens in the 7-day free trial?v
It is a scoped pilot on your real jobs. We agree on the roles, questions, and data rules with you first, then run the agent and share the results.
Do we own the code and the data?v
Yes. Ownership and exit terms are part of every engagement.
Can you build AI interviews into our own HR tech product?v
Yes. We build productized software for ISVs and can build the agent as a feature you ship and support.
