We handle your pipeline growth so you can focus on closing deals.

Accelerate your startup’s top of funnel growth with our professionally trained team of SDRs.

Hiring Sales Development Reps (SDRs) at a startup is like playing roulette...

For early-stage B2B startups, maintaining momentum is crucial. While the founders focus on perfecting the product and engaging clients, the salesforce must be actively pursuing new growth opportunities to keep the momentum alive. A poor fit on the sales team can stall this essential growth, and by the time the issue is recognized (especially remotely), it may have already cost your team valuable time and resources.

Downsides of remote SDRs, not OneThirtyFive SDRs

The OneThirtyFive Difference

OneThirty is a phone first prospecting shop for B2B startups

Phone-First Prospecting

Anticipating a decline in the effectiveness of passive text-based outreach due to the rise of large language models and stricter email standards, OneThirtyFive focuses on our phone-related outreach skillset. While we still use email and LinkedIn to support our phone efforts, direct calling remains a vital medium for connecting with prospects, gathering market feedback, and avoiding new AI-related restrictions in outreach.

While remote work offers advantages for some, we believe it can hinder the development of those early in their sales careers. That's why our professionally trained, highly motivated team of SDRs comes into our Downtown Cleveland office every day. Here, they strengthen their skillsets, learn from their peers, and, most importantly, accelerate pipeline growth for our clients.
