Spara Launches AI with $15M to Modernize Sales & Marketing

Spara, an enterprise-grade platform designed to revolutionize inbound sales, has officially launched with an impressive $15 million in seed funding. The platform offers AI-powered voice, email, and chat agents that instantly engage, qualify, and convert leads into revenue opportunities. The funding round was spearheaded by Radical Ventures and Inspired Capital, with additional backing from XYZ Ventures, FJ Labs, Remarkable Ventures, and several strategic angel investors from leading organizations including OpenAI, Anthropic, Google, Meta, Databricks, and G2. This investment will accelerate team growth, fuel product innovation, and enhance machine learning capabilities, including stronger multimodal integrations.

In today’s sales landscape, speed is everything. Research consistently shows that most buyers of B2B and high-consideration B2C products tend to purchase from the first vendor who responds to their inquiry. Yet, businesses continue to miss out on significant revenue due to sales bottlenecks. Limited rep capacity, scheduling issues, and outdated workflows often force potential customers to wait, creating friction that leads to lost opportunities.

Spara is directly addressing this challenge by leveraging cutting-edge AI technology. Its platform allows companies to deploy voice, email, and chat agents capable of delivering immediate responses whenever a buyer shows intent. Instead of requiring prospects to fill lengthy forms or wait days for follow-ups, Spara’s AI interacts with them in real time—answering questions, qualifying leads, and even booking meetings within minutes. Founded by David Walker and Zander Pease, the company is focused on creating a sales process that mirrors buyer expectations: fast, personal, and always on their terms.

David Walker, co-founder and CEO of Spara, highlighted the problem with today’s sales dynamics. “Outbound is oversaturated to the point of irrelevance, while inbound systems haven’t evolved to meet modern buyer expectations. Spara is modernizing inbound and reshaping how products are sold,” he explained.

Unlike legacy telephony systems or generic chatbots, Spara takes a highly customized approach. Each customer receives a private, tailored model trained specifically on their GTM funnel, brand voice, and qualification standards. This ensures not only accuracy but also relevance in tone and timing. Underneath, the platform harnesses enterprise-grade AI models, delivering the precision and safety required in high-value enterprise sales.

The company is already making waves with early adopters. At Rho, Spara booked over 90 meetings in just 30 days, converting 50% of qualified traffic and achieving an average chat-to-meeting time of under three minutes. According to Rho’s Chief Revenue Officer Tommy McNulty, “With Spara, we’re engaging buyers the moment they show interest – often within seconds. That kind of speed has dramatically improved our conversion rates and freed up our reps to focus on closing.”
