OneThirtyFive Reviews & Provider Details

At OneThirtyFive, we specialize in B2B sales development services tailored for high-growth startups ready to scale revenue. As a modern outsource BDR (Business Development Representative) partner, we go far beyond appointment settings; we become an extension of your brand, your process, and your go-to market strategy. Our mission is to help startups land more qualified meetings with ideal customers using an intelligent blend of outbound strategy, real-time optimization, and human-AI collaboration. We work with tech companies across SaaS, AI healthcare, fintech, and other industries who are ready to break through noisy markets and reach decision-makers faster. What sets OneThirtyFive apart is our hands-on, full-cycle BDR model. We take everything from onboarding and ICP refinement, to multi-channel prospecting, cold calling, and calendar booking. Our sales reps are trained not just to pitch, but to navigate complex B2B buying journeys, create genuine interest, and uncover pain points that convert. Through our data-driven sales playbooks, call coaching, and performance recalibration systems, we continually refine messaging and outreach based on real-time buyer feedback. Every campaign is tracked, tested, and optimized with feedback loops between AI tools and our human-led sales team to ensure better quality conversations. With a commitment to transparency, sales excellence, and client collaboration, OneThirtyFive enables startups to scale with confidence, clarity, and control over their sales funnel. Whether you're launching outbound for the first time or ready to expand your reach, we bring the talent, tools, and strategy to make it all happen. We don't just build leads. We build predictable pipelines. Let's build outbound systems that actually work.
