It is well understood that most buyers of B2B and high consideration B2C products purchase from the first vendor that responds to their inquiry. But today, most businesses lose out on significant revenue due to human bottlenecks: limited sales representative capacity, scheduling constraints, and inefficient workflows that make potential buyers wait.

Spara is tackling this problem head-on using the latest advancements in artificial intelligence. Spara’s customers deploy its voice, email, and chat AI agents to ensure instant speed-to-lead whenever and however their buyers show intent. Instead of requiring prospects to fill out forms or wait days for a response, Spara’s AI answers questions, qualifies leads, and books meetings within minutes. Co-founded by David Walker and Zander Pease, Spara enables sales & marketing to work like buyers expect – fast, personal, and on their terms.

“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,” said David Walker, co-founder and CEO of Spara. “Companies spend millions driving traffic to their websites, but the majority of leads leave without ever getting their questions answered. Spara closes that gap by allowing sales teams to capture revenue the moment it shows up.”

Unlike old-school telephony systems, generic chatbots, and static email cadences, Spara customizes a model for each customer’s go-to-market (GTM) funnel – determining not just what to say, but when to say it, and in the right tone. Each instance is powered by a private, custom model trained on that company’s unique sales motion, brand voice, and qualification criteria. Under the hood, Spara leverages enterprise-grade AI models, giving teams the power of cutting-edge language models with the safety and precision that enterprise sales demands.

“Spara is rethinking the way companies connect with buyers from the ground up, with AI at the core of their approach. The team understands that the future of sales isn’t more automation for sellers, but more immediacy and clarity for buyers. David and Zander combine deep sales and AI expertise to build the infrastructure every GTM team will need over the next decade,” said Molly Welch, Partner at Radical Ventures.

“David and Zander have the rare combination of deep GTM experience and technical fluency. As second time founders, they’ve lived the problem Spara is solving from all angles. Their clarity of vision stood out immediately," said Chris Brown of Inspired Capital.

Spara is already driving results for customers like Rho, MarketMan, Jericho Security, and TinyMCE. At Rho, the Spara platform booked over 90 meetings in 30 days, converting 50% of qualified traffic with an average chat-to-meeting-booked time under three minutes. Across early customers, Spara’s agents routinely respond within seconds – a critical factor, as conversion rates increase tenfold when companies reply within one minute, but drop drastically after five.

“With Spara, we’re engaging buyers the moment they show interest – often within seconds,” said Tommy McNulty, Chief Revenue Officer at Rho. “That kind of speed has dramatically improved our conversion rates and freed up our reps to focus on closing.”

The conversational AI market is projected to triple, from $11.6 billion in 2024 to $41.4 billion by 2030. Spara is positioned to lead a new generation of enterprise-ready, revenue-focused AI platforms.
