Leads10

Leads10 is an AI-powered B2B company prospecting and lead generation platform that turns a company website domain into a targeted list of best-fit prospect companies. Leads10 analyzes what a business sells and the pain points it solves, automatically builds an Ideal Customer Profile (ICP), and identifies real companies that match that profile. Each prospect includes a fit score from 70–100, a written match reason, industry context, company website, and Company LinkedIn Page, helping sales and business development teams understand why a company may be a relevant prospect before starting outreach. Users can review previous analyses and prospect lists from the Leads10 dashboard and export prospect results to CSV. Unlike traditional prospecting workflows that begin with manual database filters, Leads10 starts by understanding the seller’s business and offering. It is designed for B2B sales, business development, marketing, agencies, and other teams that want to reduce manual prospect research and build more focused target account lists.

LeadsAgent

LeadsAgent is an AI lead generation tool that turns a plain-English prompt into a researched, ready-to-use B2B lead list. You describe the businesses you want to reach, such as "dentists in Houston without a website" or "web agencies in Austin that need more clients", and an AI agent finds matching businesses from listing of over 200 million companies. For every business, the agent visits its website and gathers contact details: verified email addresses, phone numbers, addresses and social media profiles. Each lead receives an AI score based on reviews, website quality and online presence, so the most promising opportunities appear first. Searches run in the background, so teams can keep working while their list fills up. LeadsAgent also audits each business's web presence, flagging businesses with no website, missing HTTPS or SSL certificates, slow mobile speed and weak SEO basics. This makes it especially useful for web design, SEO and marketing agencies looking for clients who need their services. Results can be filtered and exported to CSV or Excel. LeadsAgent offers a free plan with 1,000 lead credits every 30 days, plus paid plans for higher volumes.

Mails.ai

Mails.ai is transactional email infrastructure for applications and AI agents. Developers integrate a single API to send the application-triggered email their own users are expecting — sign-in and magic links, one-time passcodes, account and security notifications, receipts, and order confirmations — and to capture the replies back as clean, structured data an app or agent can act on. It is built for transactional, permission-based email: messages a recipient asked for or expects. It is not a cold-email, bulk, outreach, or marketing tool — there are no campaigns, contact lists, audiences, or broadcast sending anywhere in the product. What you'll love about Mails.ai: - One simple API: Send and receive email in a few lines of code, and give an AI agent its own working email address in minutes. - Deliverability handled for you: DKIM, SPF, and DMARC are configured and authenticated so your mail lands where it should. - Built-in bounce and complaint handling: Every permanent bounce and complaint is captured and added to a global suppression list enforced on every send. - Reputation protection: Per-workspace rate limits and automatic pausing on adverse signals keep sending clean. - Structured inbound: Incoming replies are parsed into structured data, and every message is checked for security threats before it reaches your agent. Mails.ai is the email layer for software that sends what its users are waiting for — reliable, authenticated, transactional email with per-event pricing and no marketing bloat.
