01The difference

The "introduce-and-done" way to hire? We're ending it.

Recruiting agencies and scout media can only get as far as "showing" you a candidate. Ability is judged on paper, interview prep is dumped on your senior engineers, and post-hire retention is left to you — all for a success fee north of 30% of annual salary. saiyouba evaluates with real code and AI and ramps the right people to productivity, running on a monthly subscription alone. Hire as many as you want — the success fee is ¥0.

From finding talent to full productivity.

From finding candidates to AI interview prep, hiring, and ramping new hires to productivity through probation — every stage of hiring, once scattered, now runs in one tool.

  1. Find candidates — ranked by AI fit score

    Paste a JD; AI ranks candidates by skill, years, preferences, and live activity — strongest matches first.

  2. Grab an open slot and book the interview directly

    Book straight into the candidate's open slots — no availability emails, no scheduling links.

  3. AI generates your interview prep

    Hand it the role, your team's priorities, and what you want to probe — it drafts per-candidate questions, tasks, and deep-dive prompts.

  4. Hire all you want — ¥0 placement fee

    Zero placement fee. Subscribe, hire as many as you want — your subscription doesn't change.

  5. Probation, monitored by AIComing soon

    Through probation, AI tracks 1-on-1s, onboarding tasks, daily reports, progress, and performance — included in the plan.

  6. Ramp-up and retention, all in one tool

    Find, meet, hire, ramp — the entire hiring journey lives in one platform.

03Everything in-app

Your hiring team's tools, all inside one app.

Sourcing platforms, scheduling tools, third-party coding-test services, progress-tracking spreadsheets — we bring scattered tools together into one and protect the time of everyone involved in hiring.

Feature 01Live

AI reads 6 months of their GitHub and scores real ability.

AI reads a candidate's real activity over the last six months — commits, language mix, per-axis scores — and presents a verified skill evaluation report. Public repos and the private ones the candidate grants (anonymized) are both included, so you get a read on real ability before guessing between the lines of a resume.

  • Verified via GitHub (public + granted private repos)
  • Commits, language mix, and per-axis scores, auto-visualized
  • Can't be inflated, never goes stale — backed by their code

AI summarizes real ability — first-pass screening, done in minutes.

Feature 02Live

Turn resume screening into code review.

Rather than spending 30 minutes guessing between the lines of a paper resume, reading 5 minutes of the code they wrote themselves is far more reliable. Even the password-protected private repositories a candidate shares are viewable right on their profile. Most of the technical assessment is finished before the interview begins.

  • Confirm real implementation skill a resume can't show, in code
  • View private repositories, within the candidate's permission
  • Design technical-interview questions from their actual code

Read the candidate's working code, as-is, before the interview.

Feature 03Live

Nobody writes availability emails anymore.

See the candidate's open slots and just book one. No assistant requests, no external scheduling links, no double-booking worries. Confirmed interviews sync instantly to both Google Calendars. Lead time to an interview goes from days to seconds.

  • Book open slots directly — zero scheduling emails
  • Syncs to both calendars the instant it's confirmed
  • Dramatically shorten the days until the interview

Pick a slot and confirm — scheduling ends here.

Feature 04Live

Rank by fit — your JD against live signals.

We compare your JD's must-have skills, years of experience, and conditions against each candidate's GitHub activity, work history, preferences, and recent updates to compute a 0–100% match score. It's recalculated every time you view it, so it always reflects the candidate's "now" — read the pool top-down and you know who to meet first.

  • Auto-scored: your JD's must-haves × the candidate's real data
  • Recalculated on every view — never judge on a stale score
  • See who to meet next, at a glance

The best fits rise to the top — spend your first interview on them.

Feature 05Live

Turn 3 hours of interview prep into 30 minutes.

Per-candidate exercises, coding tests, and system-design interviews — all completed in-app. Because you discuss and work through a real-time shared document together, there are no external-tool contracts or accounts to issue. A weekly briefing even prepares sample questions and points to probe, so your seniors can focus on meeting and talking.

  • In-app coding tests and system-design exercises
  • Co-edit the same document with the candidate, in real time
  • Per-candidate weekly briefings to support your prep

From interview prep to running the test — all inside the app.

Feature 06Live

Never send another “send me three dates” email.

Send a scheduling email, wait for a reply, lose the slot to another company, start over — that back-and-forth disappears. A candidate's open slots are right there on the calendar, so you choose the interview type and book on the spot. Confirmed interviews go straight into the candidate's calendar, and filtering by type plus the full history of past interviews and evaluations is shared with your company's members on one calendar.

  • Book a candidate's open slot directly — no links or date emails
  • See every candidate's interviews by day — filter by type
  • Share past interviews and evaluation history across your company

Pick a candidate's open slot and book — the whole team sees the same schedule.

Feature 07Coming soon

Hiring isn't the finish line. We stay with you, all the way to ramp to productivity.

saiyouba accompanies the new hire with AI through the post-join probation period. 1on1 agendas and notes, initial tasks and target goals, auto-summarized daily reports and weekly progress, and performance data — all on one screen. Hiring isn't the goal; we support you until they ramp to productivity. Included in the subscription (probation period only).

  • AI prepares and summarizes 1on1 agendas and notes
  • Visualize initial tasks and target goals, track the ramp-up
  • Daily reports, weekly progress, and performance on one screen

All the way to retention beyond the hire — shipping in the next update.

04The hidden hours

Behind one hour of interviewing, 4.5 hours of hidden cost.

Reading documents, the back-and-forth of scheduling emails, preparing exercises and questions — the most expensive part of engineering hiring isn't ad spend or agency commissions, it's your seniors' time. saiyouba trims that breakdown with AI interview prep and direct booking, so senior time goes to judging real ability.

Frequently asked questions.

Yes. saiyouba is a flat monthly subscription — no placement fees at any stage. Hire one engineer or twenty, your bill doesn't change.

Scout media and agencies mostly stop at showing you a profile — interview prep and post-hire retention are on you, and each hire costs 30%+ of annual salary. saiyouba is the system that runs the whole journey — find, interview with AI-drafted prep, hire, then ramp through probation — in one tool, for a flat monthly subscription with zero placement fees.

From a candidate's last 6 months of activity, AI generates an archetype + level verdict, 6-month commit stats, a weekly activity heatmap, language breakdown, and per-axis scores with rationale. It draws on public repos plus any private repos the candidate grants read access to (the contents are anonymized; code is never exposed). You get a read on real ability before reading a resume, cutting first-pass screening time dramatically.

We compare your JD's must-haves against each candidate's GitHub activity, work history, preferences, and recent updates — recalculated live, so the score always reflects the candidate's current state.

Give it the role, your team's priorities, and what you want to probe, and it drafts per-candidate questions, coding tasks, system-design topics, and deep-dive prompts — cutting the ~3 hours your seniors spend prepping each interview so they can focus on the conversation.

Hiring isn't the finish line. Through the probation period, AI helps you run 1-on-1s, onboarding tasks and goals, summarized daily and weekly progress, and performance data — all in one screen. Included in your subscription for the probation period only. (Coming soon.)

Every candidate goes through email + GitHub-linked verification. Fake profiles and duplicate accounts are blocked at the platform level; any violation triggers an immediate suspension.

Only the fields a candidate has explicitly opted to publish appear in recruiter search. Scraping, bulk export, and transfer to third-party systems are technically blocked and contractually prohibited.

Yes, cancel anytime — no minimum term, no exit fees. No credit card required to get started.

Absolutely. saiyouba is non-exclusive — pair it with referrals, direct sourcing, or any other channel you're already running.

Hire the right people,
faster and for less.

Judge with real code and AI, find the people who truly fit, and carry them all the way to full productivity through probation. A platform that runs your entire hiring journey in one. Placement fees are ¥0, and no credit card is required.
