Signallo

Signallo is a specialized account intelligence firm that takes a fundamentally different approach to B2B research. Instead of relying on scraped data or inferred signals, the company uses structured phone conversations with real decision-makers to surface actionable insights about target accounts. Founded in 2021 and based in New York, Signallo has built a reputation for delivering data that sales and marketing teams simply can't find through traditional intent data providers or automated tools.

The core differentiator is human verification. Every data point in Signallo's database comes from a live phone conversation with someone at the account. This means the firm can uncover details that automated scraping misses: current vendor satisfaction scores, specific pain points, renewal timelines, and switching intent. For B2B companies running account-based marketing programs, this level of granularity transforms how they prioritize and engage prospects.

Signallo offers three tiers of service. The free Pulse reports provide anonymized market research across entire vendor categories, including NPS distributions and pain point rankings. The Segments product delivers pre-built lists of named accounts organized around a single confirmed pain point, priced from $2,950 per segment. For custom needs, the Dedicated service runs 80 hours of live phone research per engagement, scoped to the client's exact ICP and data requirements. This tier starts at $4,000 and the output is exclusively owned by the buyer.

Pricing for ongoing agency work is listed at $100-$149 per hour, which reflects the labor-intensive nature of phone-based research. The team of 11-50 employees handles everything from building target lists to training callers and cleaning data. Clients receive CRM-ready CSVs that can be loaded directly into their sales engagement platforms.

Signallo is best suited for B2B organizations that have a clear target account list and need to understand which accounts are actually ready to buy. The firm excels in competitive displacement scenarios, where knowing a prospect's pain with their current vendor can make or break a deal. It is less useful for companies that only need basic firmographic data or are still defining their ICP.

Overall, Signallo fills a genuine gap in the account intelligence market. While intent data providers offer volume, Signallo offers certainty. For sales teams that have been burned by inaccurate lead scores or generic contact lists, the human-verified approach provides a welcome level of confidence. The main trade-off is cost and speed -- phone research takes time and costs more per account than automated alternatives. But for high-value enterprise deals, the ROI is often substantial.
