The challenge
A serial entrepreneur with a validated idea — but no tech team to build it.
The founder had spent 12 years in enterprise recruitment and had seen the same problem everywhere: hiring managers spending 8–10 hours per role just on first-round screening. Generic video tools existed but none were built for structured, AI-graded technical assessment.
They came to us with a product concept, a 3-client pilot commitment, and a runway of 18 months. We needed to deliver an enterprise-grade SaaS platform with AI scoring, candidate portals, ATS integrations, and a hiring manager dashboard — in 12 weeks.
What they needed :
- AI-graded video & coding interview engine
- Multi-tenant SaaS with per-client branding
- ATS integrations (Greenhouse, Lever, Workday)
- Candidate portal + hiring manager dashboard
- GDPR-compliant data handling from day one

Our solution
A full-stack AI interview SaaS — from database schema to production deployment.
We ran discovery, scoped the MVP, signed an NDA, and started sprinting. Every 2 weeks the founder had a live demo. Every decision was documented. The founder owned the code from day one.
What we built in 12 weeks :
AI scoring engine — weeks 1–4
Built video interview recorder with Whisper AI transcription, GPT-4 grading against rubrics, and structured scoring output per competency.
→ Working AI scorer with 91% inter-rater reliability
Multi-tenant SaaS platform — weeks 3–8
Full multi-tenant architecture — isolated data per client, custom branding, SSO, role-based access, subscription billing via Stripe.
→ Live SaaS with 3 pilot clients onboarded
ATS integrations — weeks 7–10
Built native integrations with Greenhouse, Lever, and Workday — syncing candidates, pushing scores, and triggering next-stage actions automatically.
→ 3 ATS integrations + webhook framework
Launch & handover — weeks 11–12
Production deployment, full test suite, documentation, and a 2-day knowledge transfer session. The founder's new CTO could maintain everything from day one.
→ Full codebase + docs + 99.9% uptime SLA
The results
14 weeks. Zero disruption. Transformational outcomes.

Why clients trust us
I had an idea, 18 months of runway, and no tech team. Benthon took me from a napkin sketch to a live enterprise SaaS in 12 weeks. They didn't just build what I asked for — they helped me build the right thing. We went from 3 to 20 clients in 6 months.
