Hi, I’m Redoan Kawsar.
Full-Stack Growth Expert
Software Builder & Software Reviewer — I build SaaS and review it, hands-on.
I build practical software for small businesses — tools fitted to how they actually work. And I buy SaaS tools with my own money, use them in real work, and write up what I find: the good bits, the limits, the stuff the sales page left out. Building shows me what good software takes. Reviewing shows me where real users get stuck. Work with me, and you get both lessons — not just one.

About
“If a review doesn’t answer the question you actually Googled, it’s useless. And if it won’t tell you what the sales page left out, why bother reading it?”
I’m Redoan Kawsar. This is where I publish everything first — the lifetime deal reviews, the AI tool tests, all of it. Deals change their prices and terms all the time, so when they do, I go back and fix the old review. An old post with a wrong price on it helps nobody.
I also run Mentorsboss LLC, my agency. That’s partly why I can afford to be blunt here. Client work pays the bills, so I don’t need a sponsor to like me. If a tool disappoints me, you’ll read that in the review.
And yes — I build, too. Small businesses come to me when off-the-shelf software almost fits, but not quite: they’re wrestling spreadsheets, copying data between three tools that don’t talk to each other, or doing by hand what a small tool could do in seconds. I scope it, build it and launch it with them — a focused piece of software that does the one job they actually need done.
My expertise
Full-stack growth means the whole job, not one channel: building the product, getting it found, and turning visitors into customers. This is what I actually do, day to day — if it’s listed here, I do the work myself.
SEO
I do SEO the long way round — covering a topic properly, so Google actually trusts the site. Local work too: Business Profiles, map listings, and showing up when someone nearby is ready to buy.
Google Ads
I run campaigns where the numbers have to add up. The right keywords, tight ad groups, landing pages that don’t waste the click. If the ads cost more than they bring in, something gets fixed.
AI-Native Product Builder
Hands-on vibe coding. I build real SaaS products with AI doing a lot of the heavy lifting — my own products, and practical tools for small-business clients. Not demos: things people can sign up for and use. First idea to launch day, I’m in it the whole way.
AI Enthusiast
I spend a probably unhealthy amount of time on agentic AI — building agents, setting them loose on real tasks, and noting where they shine and where they fall over. Then I teach what I’ve learned on YouTube, in plain language, so you can skip the confusing part.
Content Creation & Research
I don’t write first and research later. I check what’s already ranking, see what competitors missed, read the deal terms twice — then write it plainly, so you can finish the page and actually decide.
YouTube Reviews
Some people would rather watch than read. Fair enough. For the bigger reviews I record my screen, click through everything, and talk through whether I’d spend my own money on it.

Build & Review
Two offers. Both hands-on.
Most reviewers have never shipped a product. Most builders never sit and test a competitor properly. I do both, every week — and each side makes the other one better.
Need a tool built for your business?
Tell me the job that’s eating your week — leads scattered across spreadsheets, follow-ups you forget, reports you build by hand. If a small, focused tool can take it off your plate, I’ll build it: we scope it together, I build it with AI-assisted development so it ships fast, and your team uses it from day one. No bloated platform. No features you didn’t ask for. And if a tool won’t fix it, I’ll tell you that instead of selling you one.
Start a build conversation →Built a SaaS product? Get it reviewed properly.
Send me your product and I’ll do what I do with every tool on this site: sign up, pay attention, and use it in real work — not skim the landing page. You’ll get an honest, detailed review in front of buyers who are actively shopping for software like yours. And because I build software myself, the feedback you get back is the kind a builder actually understands.

My agency and my two deal sites — this is where most of my week actually goes.
Mentorsboss LLC
My agency, and where I take on client work. I treat a client’s budget the way I treat my own money — carefully, and with the numbers in plain view.
Work with Mentorsboss →TopSaaSDeals
Where I keep track of lifetime deals as they land on AppSumo and EarlyBird. There’s also a launch board — a bit like Product Hunt, but for SaaS — where founders can put a new product in front of buyers.
Visit topsaasdeals.com ↗SaaSDealsZone
A smaller, simpler idea: deals I’ve checked myself, all in one place. For people who like good software but hate paying full price for it. So… most of us.

You’re looking at it. This is where the longer reviews live — the ones where I had a lot to say — plus the buying guides I keep updated as deals come and go.

Two products of my own, almost ready
I’ve spent a long time reviewing other people’s software. It felt like time to build my own. I’m keeping the names under wraps until launch day — but the countdown below is very real.

A new SaaS marketplace
A place for good SaaS products to get found, and for buyers to find them without digging through ten different sites. I’ve watched this market closely for years. This is the thing I kept wishing existed.
Name revealed at launchWant a heads-up when it launches? Drop your email and I’ll send one message on launch day. That’s it — no newsletter you didn’t ask for.
Lead generation software
A tool for finding people who might actually buy from you. I’ve tested a lot of outreach and sales software over the years. The good bits stuck with me. So did the annoying bits.
Name revealed at launchWant a heads-up when it launches? Drop your email and I’ll send one message on launch day. That’s it — no newsletter you didn’t ask for.
Both should be live within two months. The countdown ends 14 January 2027 — hold me to it.
Featured reviews & deal guides
Start with these. And if you already know what you’re shopping for, the filters below will narrow things down fast.
NeuronWriter Review
The content editor I actually use for my own writing. I wanted to know if its SERP analysis is genuinely useful, or just a nice-looking score. Here’s what I found.
ManyReach Review
For sending cold email at scale. I checked the deliverability, the real sending limits (not the ones on the pricing page), and how it stacks up against the other outreach tools I’ve tried.
pCloud Lifetime Deal
Pay once, keep your cloud storage for life. Sounds great, right? So I did the maths against a monthly plan — and read the fine print most people skip.
HeyGen Lifetime Deal
Videos without filming yourself. I tested how convincing the avatars look, how quickly the credits disappear, and who should actually bother with it.
Pabbly Connect Lifetime Deal
Automate the boring stuff without counting every task like it costs money. Because with Zapier, it does. Here’s the honest side-by-side.
Best SaaS Lifetime Deals
Every lifetime deal I’ve checked and would still put my name next to, sorted by category. I update this one often — deals don’t stay live forever.
Insighto.ai Review
AI voice and chat agents that talk to your customers for you. Setup was easier than I expected. Finding the limits took a little longer.
Hopper HQ Review
Scheduling social posts for small teams. Nothing flashy — but does it hold up week after week? That’s what I wanted to know.
Best AI Lifetime Deals
AI tools you can buy once instead of renting forever. I left out the ones with stingy credits — and the ones I’m not sure will still be around next year.
Got a SaaS product launching soon?
Put it on the TopSaaSDeals launch board. It’s a bit like Product Hunt, except everyone reading it is there because they love a lifetime deal. If that’s your crowd, come and list it.

Featured categories
Everything I publish falls into one of these four buckets. Hover over a category — or tap it — to see what’s inside before you click through.
AI tools I’ve bought with my own money and kept using — or quietly stopped using, which tells you just as much.
Outreach and automation tools, judged on the numbers they actually deliver — not the ones on the pricing page.
The everyday tools — storage, scheduling, the unglamorous stuff that either saves you an hour a week or doesn’t.
Not sure where to start? These hubs pull every deal I’d still put my name next to into one page, sorted by category.
