Warmly

Warmly is an account-level and person-level website deanonymization platform that extends beyond visitor identification into automated outbound sequences — triggering email, LinkedIn, and Slack outreach to identified visitors without manual SDR intervention. The company has raised approximately $23M in total funding and competes directly with RB2B at the identification layer while targeting higher-ACV customers with its orchestration capabilities. Warmly’s $500–$1,500/month entry price positions it as an intent-data-plus-automation platform rather than a pure signal tool.

HeyReach

HeyReach is a LinkedIn automation platform built specifically for agencies and multi-seat GTM teams, enabling campaign management across multiple LinkedIn accounts from a single interface. Bootstrapped and profitable, the company has captured meaningful share of the vacuum left by Phantombuster’s decline and the general maturation of LinkedIn as an outbound channel. Estimated ARR of $5–10M as of early 2026, with growth driven entirely by product-led distribution and community word-of-mouth.

11x

11x builds AI sales development representatives — Alice (outbound email and LinkedIn) and Mike (inbound call handling) — designed to operate as autonomous agents rather than workflow automation. The company raised a $20M Series A from Benchmark in mid-2024 at a reported $50M valuation, generating significant press. That press cycle was followed by a difficult 2025 in which multiple customers and former employees publicly alleged inflated ARR figures, rapid churn, and gap between demo performance and production reliability. As of April 2026, 11x is a company with a compelling product vision and serious execution credibility questions.

Gong

Gong is the conversation intelligence and revenue intelligence platform that defined its category, having reached a peak valuation of approximately $7.25 billion in its 2021 Series E raise backed by Franklin Templeton, Coatue, and Sequoia. The platform records, transcribes, and analyzes sales calls and emails, surfacing deal risk signals, coaching opportunities, and competitive intelligence across the revenue organization. Backed by SoftBank and Sequoia among others, Gong became the default enterprise answer to the question of what actually happens in sales conversations and how to replicate top-performer behaviors at scale. Since the 2021 peak, Gong’s valuation has been flat against a broader SaaS multiple compression — the company has not achieved a public listing despite long-rumored IPO intentions, and secondary market trades suggest current valuation is materially below the $7.25B peak. As of May 2026, Gong remains the category standard for conversation intelligence at enterprise scale, with no direct competitor having displaced it in the upmarket segment despite Chorus’s ZoomInfo integration, Clari’s expansion into the space, and multiple AI-native entrants targeting the mid-market. The platform’s data moat — years of sales conversation data training its AI models — is the structural differentiation that keeps Gong ahead of competitors who are building features but not catching up on model quality.

6sense

6sense is the enterprise intent data and account-based marketing platform that has defined the ABM infrastructure category since its Series D growth phase, reaching a peak reported valuation of approximately $5.2 billion. Backed by Insight Partners with additional participation from Tiger Global and D1 Capital, 6sense combines B2B buyer intent signals, predictive AI scoring, and multichannel ABM orchestration into a single platform targeting enterprise revenue teams. The platform aggregates intent signals from across the web — including content consumption, keyword research behavior, and third-party publisher networks — and layers predictive models to score accounts by purchase readiness stage. 6sense’s core value proposition is directing sales and marketing resources toward accounts that are actively in-market rather than spraying campaigns at full ICP lists. The platform integrates deeply with Salesforce, Marketo, HubSpot, and major ad platforms, enabling marketing teams to trigger LinkedIn and display ad campaigns against accounts that 6sense scores as late-stage buyers. As of May 2026, 6sense remains the market leader in enterprise intent data, though the valuation premium it commanded in 2021-2022 has compressed alongside the broader B2B SaaS multiple contraction. Bombora and Demandbase are the primary platform-level competitors; G2 Buyer Intent serves the mid-market with more accessible pricing and review-signal-based intent data.

Outreach

Outreach is the sales engagement incumbent — the platform that effectively invented the modern SDR sequencing category and held the top position through the enterprise adoption wave of 2016–2021. The company raised approximately $489M in total funding, peaked at a $4.4B valuation in 2021, and has since navigated a painful recalibration as the market it created got disrupted by cheaper, faster, AI-native competitors. Outreach acquired Sameplan (deal execution software) in 2024 and launched Kaia, its AI sales assistant, as the centerpiece of an AI-first repositioning. As of April 2026, Outreach is a platform with genuine enterprise depth fighting a two-front war: defending against Salesloft from above and Smartlead and Instantly from below.

ZoomInfo

ZoomInfo is the data incumbent that built the enterprise B2B contact and company database category, went public on Nasdaq in 2020 (ticker: GTM), and has spent the years since defending its position from Apollo’s aggressive PLG expansion and Clay’s waterfall enrichment architecture. The company acquired Chorus.ai in 2021 for $575M to add conversation intelligence, and has continued building toward a full go-to-market platform. As of April 2026, ZoomInfo has the deepest enterprise data asset in the category — particularly for direct dials and intent signals at the Fortune-5000 level — but its price-to-value ratio versus Apollo has never been harder to justify for companies under $100M in revenue.

n8n

n8n is an open-source workflow automation platform that competes directly with Zapier and Make at the technical operator tier — offering self-hosting, unlimited workflows, and a node-based visual builder with code execution capabilities. The company raised a €60M Series B from Highland Europe in 2025, validating the enterprise open-source automation category. n8n’s self-hostable architecture and code-alongside-UI design makes it the default choice for GTM engineers and RevOps operators who want Zapier’s ease with developer-grade control.

Artisan

Artisan is an AI sales development representative platform centered on Ava, its AI BDR, which handles prospect research, email personalization, outbound sequencing, and meeting booking autonomously. The company raised a $25M Series A in 2024 from Foundation Capital and Y Combinator and has been quieter about controversy than its better-funded competitor 11x — a distinction that matters enormously in a category where trust is the primary evaluation criterion. Practitioner reports as of early 2026 consistently place Artisan’s production output quality above 11x’s, with more reliable deliverability, more coherent personalization, and fewer hallucinated references. If you are going to buy an AI SDR, Artisan is currently the most defensible choice.

RB2B

RB2B is a person-level website deanonymization tool founded by Adam Robinson, identifying not just the company but the specific individual visiting your website and pushing that record — with LinkedIn profile, email, and job title — to Slack in real time. The product launched in early 2024 with a free tier as the primary acquisition wedge and generated significant viral attention among GTM operators. Privacy concerns and IP data methodology questions are legitimate and should be evaluated before deployment.
