SustLabs is a leading smart-energy startup that helps households and small offices decode electricity usage without sensors. By analyzing smart meter data for utilities, appliance manufacturers, and research partners, the company delivers actionable insights on energy consumption. With a team of 50 and rapidly growing, SustLabs needed a faster and more scalable way to hire across both technical and non-technical roles.
“Screening over 300 CVs, shortlisting candidates, calling them up, and getting them tested was extremely taxing. With Babblebots, I finally had a platform that automated the first round and mapped every candidate from application to offer giving me complete visibility.”

The Challenge: A Lean HR Team in a High-Growth Company
SustLabs is expanding quickly, but its HR team consists of a single recruiter—Reedhima Mishra. Hiring managers are often co-founders or functional heads, leaving limited bandwidth to screen hundreds of candidates. The volume of applicants, combined with evolving role requirements, made traditional hiring extremely time-consuming and inefficient.
The Babblebots Solution: AI-First Screening and Interviewing
Using Babblebots’ AI Recruiters, SustLabs automated the entire first-round screening process. AI designed custom interview flows, matched skills to job descriptions, scored candidates across technical and behavioral dimensions, and provided structured shortlists. The dashboard allowed Reedhima to track every candidate’s movement from round 1 to offer without manual follow-ups.
Impact: Faster Hiring Cycles, Higher Completion Rates, Better Talent
For the Machine Learning role, 28 of 42 candidates submitted interviews, with 23 completing them within 48 hours. For Web Development, over 109 candidates engaged, enabling SustLabs to hire someone within 24 hours end-to-end. Across three tech roles, Reedhima spent only six hours total to shortlist eight strong candidates and extend four offers. Before Babblebots, this process took roughly three weeks.
The Future: SustLabs Scales Hiring With AI
With consistent success across tech and non-tech roles, SustLabs now relies heavily on Babblebots’ AI Recruiters for ongoing hiring. Reedhima shared that she cannot imagine returning to manual screening, and the company continues expanding its use of AI-driven candidate evaluation, technical assessments, and applicant tracking.
