What Leadbay does
Leadbay is a B2B AI prospecting platform, founded in 2023 and operated as LeadBay SAS (registered in France with a San Francisco regional headquarters), that discovers and qualifies small and medium businesses with little or no digital footprint — the "invisible economy" of plumbers, hairdressers, hotels, restaurants, construction firms, manufacturers, and other traditional field-sales targets that incumbents like Sales Navigator, Clay, and ZoomInfo are unable to score. The product is built around a proprietary domain-specific AI engine: the first-generation Leadbay COMPASS model (January 2024) was followed by the Lucid-Sea-V1 hybrid model (June 2025), a text-and-tabular inference model that combines fine-tuning of open-source models with internal CRM/ERP/CSV knowledge and crawled public web data, and that underpins features such as Monitor (pipeline scoring), Discover (new ICP lead generation), Timeline (new market clusters), Map (field-visit prospecting), Web Fetch, Email Auto-draft, Talking Points, AI Summary, and an integrated AI Chat. Leadbay 2.0 (September 2025) added a Manager Dashboard and a free test tier, and a mobile app launched in March 2025 to put predictive prospecting in the field.
The company monetises through a four-tier SaaS model — Free (€0/user/month with daily quota and credit top-ups), More (€100/user/month, €80 annual), Scale (€400/user/month, €320 annual) — plus a custom Enterprise tier with CRM, Salesforce, and data-lake integrations, a dedicated DPO, and an enterprise API. Distribution combines product-led growth via the self-serve signup, a Bootcamp onboarding program (new cohorts every 15 days), direct enterprise sales, and a three-tier certified partner program (Ambassador, Reseller-Integrator, Strategic) with named partners including KPMG, Microsoft, Stema Partners, AxeCapital, Hyperstack, Need Leads, Qolaig, Heracly, and FLOWLAB. Leadbay has raised approximately $4.8M to date ($4.3M seed in May 2026 from Y Combinator, Rebel Ventures, Roosh Ventures, Inovexus, TS Ventures, Alumni Ventures, Bright Ventures, Transpose Platform, and Deel Ventures; $500K in December 2025) and counts L'Oréal, Saint-Gobain, Deel, HomeSpirit (70+ reps running 100% mobile), Fiderim, and DécorAlliance among named customers.

Leadbay product offering
Product offeringCore offering
Leadbay develops a B2B AI prospecting SaaS platform that discovers and qualifies SMBs with low digital data and few online signals — the 'invisible economy' — for B2B sales teams in traditional verticals such as construction, hospitality, manufacturing, and services. The platform is powered by proprietary domain-specific AI models (COMPASS and Lucid-Sea-V1) that predict lead win/loss, surface new ICP clusters, integrate with CRM/ERP/data lakes, and provide a mobile-first field prospecting experience.
Product overview
Leadbay is a single B2B AI prospecting platform (with web and mobile clients) operated by LeadBay SAS, structured around one core platform and a portfolio of named modules and proprietary models. The core platform — Leadbay — combines four flagship features: Monitor (CRM/ERP/Excel scoring), Discover (new ICP lead generation), Timeline (new market-cluster exploration), and Map (field-visit planning), and was significantly upgraded as Leadbay 2.0 in September 2025. The mobile-first Leadbay Mobile App (March 2025) extends the same engine to sales reps in the field, while the Leadbay Manager Dashboard (September 2025) provides pre-CRM visibility for sales leaders. The platform is powered by Leadbay's proprietary domain-specific AI models — first COMPASS (January 2024), then the Lucid-Sea-V1 hybrid model (June 2025) — which underpin generative features such as Web Fetch, Email Auto-draft, Talking Points, AI Summary, and Notes. Adoption and change management are delivered through the Leadbay Prospection Bootcamp and the Leadbay Partner Program, which together form the go-to-market layer around the core product.

Leadbay competitors and assessment
Company assessmentDirect peers
- Cognism: Cognism is a B2B sales intelligence provider with strong coverage of the EMEA market, offering contact data, intent signals, and sales prospecting tools. It is a particularly relevant peer given Leadbay's French/European roots and mid-market focus.
- Lusha: Lusha provides B2B contact and company data enrichment, with browser-extensions and a self-serve model popular with SMB sales teams. Like Leadbay, Lusha targets individual sales reps and SMB sales organisations for contact discovery.
- Clay: Clay is an AI-first B2B prospecting platform that combines waterfall enrichment, AI-driven research, and outreach personalisation. It directly competes with Leadbay in modern, AI-native sales prospecting, although Clay is more oriented toward tech/SaaS ICPs while Leadbay targets information-poor SMBs.
- Apollo.io: Apollo.io is a B2B sales intelligence and engagement platform offering a large contact database, lead scoring, and sequencing tools. It is a direct peer in B2B lead generation and sales prospecting at the SMB/mid-market level where Leadbay also operates.
Broad incumbents
- 6sense: 6sense is an account-based sales intelligence platform combining intent data, predictive scoring, and orchestration. It overlaps with Leadbay in AI-driven lead scoring and prioritisation but operates more at the enterprise ABM level.
- Outreach: Outreach is a sales execution platform combining sequencing, workflow automation, and AI-driven recommendations. It is a broad incumbent in the same B2B sales tooling category where Leadbay operates.
- ZoomInfo: ZoomInfo is the largest B2B sales intelligence and go-to-market platform, offering an extensive company and contact database plus intent data and orchestration. Leadbay explicitly names it as a competitor it aims to outperform for the low-data SMB segment.
- Salesloft: Salesloft is a leading sales engagement platform offering cadences, email, dialer, and conversation intelligence. It complements Leadbay at the activation stage of the funnel and overlaps in targeting B2B sales reps as end users.
- LinkedIn Sales Navigator: LinkedIn Sales Navigator is the incumbent social-graph-based B2B prospecting tool from LinkedIn. Leadbay explicitly positions against Sales Navigator for the segment of SMBs lacking digital signals, where LinkedIn's coverage is weak.
Emerging players
- Regie.ai: Regie.ai is an AI-powered B2B sales content and prospecting platform that generates personalised outreach and manages sequences. It is an emerging peer with overlapping AI-driven prospecting capabilities, though with a stronger emphasis on generative outbound content than on low-data SMB discovery.
