A SaaS? tool that turns a founder's website into a daily queue of researched, qualified prospects and ready-to-send personalized outreach.

Solo B2B? founders spend too much time manually finding and qualifying leads instead of selling. Existing lead databases often return large undifferentiated lists, leaving the founder to research each company, identify the right decision-maker, write outreach, and track replies across tools. The pain is not simply lead volume, but the missing workflow between raw prospect data and qualified conversations.
Build a web app where a founder enters their website and ideal customer notes, then the system generates a target customer profile and finds matching companies from public business directories, LinkedIn-style company data, job posts, funding/news signals, and website metadata. The first product surface is a daily prospect inbox showing company fit, decision-maker candidates, evidence for why they match, and editable personalized email drafts. Over time, it can add CRM? sync, reply tracking, and multi-channel sequencing, but the first version should focus on qualified lead discovery plus explainable outreach drafts.
AI makes account research and first-draft personalization cheaper, while solo founders are increasingly shipping products faster than they can reliably find customers. Generic lead databases are crowded, but a workflow-specific prospecting inbox for small B2B? teams remains buildable as a focused wedge.

Hey friends… I’m building Mangos.ai. It's a desktop app that helps founders distribute their products through social and cold outreach. It finds relevant people and conversations across Reddit, X, Facebook, Instagram, and Threads, researches each prospect, scores who’s worth contacting, and drafts personalized replies and DMs. The thing I just shipped is the one users have been asking me for: **a cold email research and outreach agent.** Most solo founders know cold email can work. The problem is everything you have to do before sending one: Build a list. Visit every website. Work out what the company does. Find the right person. Look for contact information. Research enough context to write something personal. Then create and manage the follow-ups. Do that properly for twenty prospects and your afternoon is gone. So Mangos now does the boring part from your computer. There are two ways to use it: **If you don’t have a data vendor:** Tell the agent what kinds of businesses you’re looking for. It can discover prospects through places like Google Maps, Product Hunt, Hacker News, and company websites. It visits each site, understands the business, researches the people behind it, gathers publicly available contact information, and drafts a personalized three-step email sequence. **If you already have a data vendor:** Upload the list you built there, even if it only contains basic contact information. Mangos uses its in-app browser to research every person and company: who they are, what they do, where they work, what the company sells, and what might make your outreach relevant. It then turns that research into a personalized three-step sequence that you can review, edit, schedule, and manage. Everything runs through your computer using an in-app browser and scraping engine. Your computer becomes the researcher and email drafter you can run whenever you want. The same principle applies to a...
I've built a couple of products over the last year, and every time I hit the same wall. Building isn't the hard part anymore. Finding the right people consistently is. Most tools give me thousands of leads. But I still have to: * Figure out who's actually a good fit. * Research every company. * Find the right decision-maker. * Write personalized outreach. * Manage conversations across multiple platforms. It still feels like 80% manual work. So I've been thinking about building something different. You paste your website once. The AI understands your product, continuously finds high-intent prospects, researches them, starts personalized conversations, and manages everything from one inbox. The goal isn't more leads. The goal is opening the app every morning and seeing a few high-quality conversations already waiting for you. I'm curious if anyone else feels this pain, or if you've already found a workflow that solves it.
