Products that do what I made email validation tool does
Hey HN, I’m a solopreneur and have been in the SaaS space for the past 3 years. My last 3 startups failed, and a common challenge in all of them was figuring out how to reach my audience. Recently I started with cold outreach (its a struggle, since I dont have much experience with marketing). I am finding leads mainly using exa.ai websets (web vector search, extremelly good for multiple use cases, recommend checking them out) and then sending them through smartlead. I ran the campaign for the past 30 days and 12-15% emails always bounced. This wasted my email credits & chances of reaching…

Hi HN! I made a really quick web app to help people validate their ideas. The app is a simple landing page builder, but every page includes a really simple Yes/No "Are You Interested?" poll. Every vote is recorded and tracked, and if they click yes they are brought to a page where they can submit an email. This makes validating ideas super easy because you can post your link to different communities and get statistically significant results as well as build an email list. Given an hour, you could easily create 50 different landing pages and be able to validate your ideas in bulk. The…

Hi HN! I'm Louw, founder of the enterprise insurtech scale-up Root[0]. Over the last 8 years, my inbox has been flooded with unsolicited emails, especially since early 2023. Recruitment services, outsourced software development agencies, and a crazy amount of lead generation services (thanks, Apollo!) drowned my inbox. To solve this, I created Unspam. Initially, it was a simple tool for myself and fellow founders to reduce noise. And it worked — about 10% of my emails were swiftly and accurately categorized as unsolicited messages. Given its success, I've decided to package and share Unspam…

Hi there, So a buddy a couple of days ago came up with the idea for a new SaaS product regarding gpt and image generation. We did a quick MVP that barely works, it breaks almost 50% of the time but we still wanted to validate the idea before going all in. We have almost 1k followers on Twitter together. Did a quick post describing the idea with a stripe link in the comments with a 5$ value, no landing page, and no shipped product. In exchange, the buyers become beta users. Around 30 mins later we got our first sale next 30 mins another 5$ and so on. Do we consider the idea validated? The…

I'm tired of seeing founders building stuff for months and years that nobody would ever pay for. They just don't see it, like most other founders learn to do. Business validation = making money, and nothing else really. If you really wanna make money this year, I can help you do it.

Capturing emails always sucked. I don't want to add a full-blown newsletter API. That's why I've created my own tool. Would love your feedback on this

Hey HN, I’ve been working on ElevateSells — an AI sales agent designed to take the pain out of cold outreach for solo founders and small teams. Here’s how it works: You ask the AI to generate leads or manually use the advanced lead search built in tool. You tell the AI what your business does and what problem it solve. It writes very personalized cold emails, sends them, and follows up — all automatically. You still control the voice and audience — the AI just handles the research, writing, timing, and sending. I built it after burning out managing multiple tools for lead gen, email copy,…

Hi, i was wondering what the HN community thinks of this email tone check application? Do you think this can be done better with open-source? Disclaimer: I am neither a founder or an employee at the company. Just someone who had a similar idea.

Hey HN, I've just begun my solopreneur journey. I've been a "serial starter" - often starting projects and never seeing them through, and I have finally finished my first project! Maybe this sentiment resonants with some of you, let me know in the comments below I built this tool as a simple no-risk method for turning more visitors into customers by A/B testing your sale promotions and automatically displaying the promotion with the highest conversion rate. Did you know that increasing your conversion rate by just half a percent can have a dramatic impact on your sales without needing…

hi, TLDR: I’m a programmer/solopreneur who got into online marketing, built a marketplace website, and just finished a book about online marketing that’ll appeal to programmers and other technical types. Now I want to recruit early readers to review it (good or bad–as your please) on Amazon. Any takers (non-binding, of course), contact me here: https://www.jackkinsella.ie/customer_support_requests/new Long Version: Six years ago, I programmed a web app, but it didn’t get much traffic, so I started researching everything on online marketing. I thought the best way to…

Hey HN, I’m a solopreneur and have been in the SaaS space for the past 3 years. My last three startups failed, and a common challenge in all of them was figuring out how to reach my audience. SEO always seemed like the answer, but I didn’t know where to start. It felt overwhelming—so many technical terms like keyword research, clustering, SERP, semantics, topical authority… I could go on. That’s where my idea for my next startup came from: building an all-in-one SEO tool that’s easy to use and understand. The complexity of SEO is hidden behind a simple UI, and the only thing users need to do…

Hi everyone. Over the weekend, I built a tool for finding contacts using AI. Here's the backstory. My partner and I are working on an agrotech startup – we’re building telematics for agricultural machinery. Most of our sales come through cold outreach: you search for contacts, message them, call, make deals and so on We also do indiehacking, because agrotech is slow and a sometimes boring. At some point, we got tired of manually collecting contacts from the internet, so we built a AI tool for that. It turned out to be super helpful, and we decided to share it with the world. If anyone here…

Hi HN, I created a (realistic) fake tweet generator to make my mum believe I'm successful until I get there for real haha. Now I can proudly (not) show her Elon endorsed my SaaS! It's 100% free to use and I tried to make it as realistic as possible while being easy to use. There are already existing similar tools but I could not find one that automatically pre-fills data from a twitter username and that handles business accounts (square picture/gold badge/company picture) so I built it. I would love to hear your feedback or suggestions!

Hey everyone! I wanted to share a tool I built to help you quickly find potential customers across social media for your product. It's a really simple concept: you simply paste in your landing page URL, and it shows you highly relevant posts across Reddit (Working to integrate few more) from people who likely need your product or service. For example, if you have a minimal to-do list app, it will show you posts like "Anyone know of a minimal to-do list app?" or "Really starting to dislike how complex Notion is." These posts are from the last 48 hours, updated in real-time, and uniquely…

Promptly is my first SaaS Project. I built it because I wanted to refine my dev skills and also to have a central place to store my prompts for GPT, Midjourney, and other AI platform and systems. Would love some feedback on the website itself, as well as advice on how I should go about the marketing

As a product manager I've used different feedback tools and almost never liked the design and experience of the widget. And pricing of some existing tools is just way too high, at least for indie makers or small businesses ($35 for 100 responses...). That's why I've launched Freddy Feedback (today!). You can find it on www.freddyfeedback.com. Curious to hear your feedback (very meta ;-)).

After a month of diving into Next.js for the first time, I built a cool app that helps SaaS founders connect with users, tweak their offerings, and boost revenue. You can easily add feedback forms to your website to gather and analyze customer feedback whenever you want. It has a 30-second setup, requires no coding, and is compatible with WordPress, etc. Tell me, guys, what do you think, knowing I'm just a beginner?

Hello HN, around October last year, I started to work on campaignkit.cc as a side project. It is a service to detect invalid and malicious email addresses. You can upload text files, and use the REST API or direct integration to retrieve a detailed report for each email address. End of March I added Stripe Payments and got my first paying customers via SEM. A coworker suggested starting a Show HN thread, so here we are :) I used golang for the backend since I wanted something lightweight with fast compilation times (coming from scala). For the frontend, I'm using Next.js and TailwindUI. On…

Hey HN, I'm Aydin, a 13-year-old developer and indie maker looking to improve the world with my small startups. Recently, I built 2 micro SaaS projects. I spent days & weeks coding features, always telling myself that after coding one more feature I was for sure to get traction. This never happened. The reason: I never launched. With IndieReq, you can launch your startup fast and get real user feedback so you know exactly what features to ship and improve. All you have to do is sign up for free, create a feedback board, and share the public link with your users. It's that easy! If you've…

Hey HN,I'm Arthur, solo founder here. After struggling to get consistent traffic for my own startup, I realized I was spending more time guessing how to market than actually building. So I made something small but useful. MediaFast is a simple tool that gives you daily marketing roadmaps for Reddit, X, and LinkedIn. No fluff, just concrete tasks that help you get seen. It covers: – Where and how to post on Reddit without getting banned – What to tweet to get engagement as a SaaS founder – How to grow LinkedIn with cold DMs and soft content Since launching, I’ve gotten 15k+ visitors and $5.7k…
