Last updated: May 2026.
When I started my first company in 2022, I spent three weeks researching tools. I subscribed to 17 different services in the first month; most of which I never used.
Two years and three startups later, I’ve figured out which tools actually matter. Not the ones that look cool in Product Hunt screenshots, but the ones that solve real problems founders face every single day.
This list isn’t everything that exists. It’s everything that’s earned a permanent spot in my founder toolkit.
1. LLCtoolkitPro – LLC Formation & Cost Planning
What it does: Calculates exact LLC costs by state, generates formation documents, and walks you through banking and compliance setup.
Why it made the list:
I paid $2,400 to form my first LLC because I didn’t know what I was doing. A formation service charged me $499, then upsold me on registered agent ($299/year), operating agreement ($299), and trademark search ($1,499 that I didn’t need).
The state filing fee was $90. Everything else was inflated.
LLCtoolkitPro shows you the real costs upfront; not just the filing fee everyone advertises, but registered agent fees, annual taxes, and ongoing compliance costs. Then it generates the documents you need and walks you through each step.
What makes it different:
Most formation services make money by hiding costs and upselling. This tool makes money by being transparent. You see exactly what you’ll pay over 5 years before you commit to a state.
It’s especially good for non-US founders. The Stripe setup guide alone saved me hours of confusion when I was helping an Indian founder get his LLC connected to payment processing.
Pricing: Starting at $29 (vs $300-$2,000 for formation services)
Best for: First-time founders, non-US residents forming US LLCs, anyone who wants to understand costs before committing
My take: This is the tool I wish existed when I started. Would’ve saved me $2,000+ in unnecessary fees.

2. Mercury – Business Banking That Doesn’t Suck
What it does: Free business checking accounts with clean interface, fast approval, and no minimum balances.
Why it made the list:
I tried Chase Business Banking first. They wanted me to visit a branch with my formation documents, maintain a $1,500 minimum balance, or pay $15/month in fees.
Mercury approved my account in 3 days without me leaving my apartment. Zero monthly fees. Zero minimums. The interface actually makes sense.
What makes it different:
Traditional banks built their systems in the 1990s and it shows. Mercury was built for startups in 2026. The dashboard is clean, transfers are instant, and they integrate with every tool you’re already using.
They also accept non-US residents, which is huge for international founders who can’t walk into a US bank branch.
Pricing: $0/month
Best for: Online businesses, startups, international founders, anyone tired of banking interfaces from 1998
My take: Switched from Chase after six months of frustration. Should’ve started here.
3. Stripe – Payment Processing (The Only Real Option)
What it does: Accepts credit cards, subscriptions, and international payments with developer-friendly APIs.
Why it made the list:
If you’re selling anything online, you’ll end up using Stripe. I tried alternatives; they all have issues.
PayPal works but their interface is cluttered and holds funds randomly. Square is great for in-person but limited online. Stripe just works, integrates with everything, and gets out of your way.
What makes it different:
Stripe’s documentation is so good that non-technical founders can set up payment forms. Their dashboard makes financial reporting painless. And they innovate constantly without breaking existing integrations.
Pricing: 2.9% + 30¢ per transaction
Best for: Any business accepting online payments
My take: Industry standard for a reason. Just use Stripe.
4. Notion – Company Wiki + Project Management + Docs
What it does: All-in-one workspace for notes, docs, databases, and project management.
Why it made the list:
I used to have notes in Apple Notes, project tasks in Trello, docs in Google Docs, and a wiki in Confluence. Switching between them killed productivity.
Notion replaced all of it. Every doc, every project, every database lives in one place with a clean search function.
What makes it different:
Notion adapts to how you work instead of forcing you into rigid structures. Start with a simple note, turn it into a database if needed, link to other pages, embed files. It grows with your company.
The free plan is generous enough for most early startups. By the time you need to pay, you’re making enough revenue that $10/month per person doesn’t matter.
Pricing: Free for individuals, $10/month per person for teams
Best for: Remote teams, founders who wear multiple hats, anyone drowning in different tools
My take: Took me a week to fully migrate, haven’t looked back since. Everything in one searchable place.
5. Relay – Business Banking (The Multi-Account Alternative)
What it does: Free business banking with up to 20 checking accounts. Yes, twenty.
Why it made the list:
I use Mercury for my main operating account. But I also use Relay to create separate accounts for:
- Tax savings (25% of revenue goes here automatically)
- Marketing budget
- Product development fund
- Emergency reserves
Having separate accounts makes budgeting visual. I can see exactly how much is allocated where without spreadsheets.
What makes it different:
Most banks charge per additional account. Relay gives you 20 for free. You can set up automated transfers between them based on rules you define.
Pricing: $0/month
Best for: Founders who want better financial visibility, businesses with multiple revenue streams, anyone who struggles with budgeting
My take: Use Mercury as your main bank, Relay for organized cash flow management.
6. Loom – Async Video Communication
What it does: Record quick video messages with your screen, camera, or both. Share with a link.
Why it made the list:
Writing detailed explanations takes 20 minutes. Recording a 2-minute Loom explaining the same thing takes 2 minutes.
I use it for:
- Bug reports (show the bug instead of describing it)
- Feature explanations (walk through new features for customers)
- Team updates (record instead of scheduling meetings)
- Client presentations (send async instead of scheduling calls)
What makes it different:
Loom is stupid simple. Click record, talk, stop, share link. No uploading to YouTube, no fiddling with video editors, no complexity.
Pricing: Free for 25 videos, $12.50/month for unlimited
Best for: Remote teams, customer support, anyone tired of explaining things in long emails
My take: Saves me 5+ hours per week in unnecessary meetings and long email threads.
7. Cal.com – Scheduling That Isn’t Calendly
What it does: Scheduling tool that syncs with your calendar and lets people book time with you.
Why it made the list:
Calendly works fine but charges $10/month for basic features. Cal.com is open source, looks better, and is free for most use cases.
I have separate booking links for:
- Sales calls (30 minutes)
- Customer support (15 minutes)
- Partnership discussions (45 minutes)
Each link has different availability rules. Sales calls only during morning hours. Support calls only on specific days.
What makes it different:
It’s open source, so if you’re technical, you can self-host it. Even the hosted version is cheaper than Calendly with more customization options.
Pricing: Free for individuals, $12/month for teams
Best for: Anyone scheduling meetings regularly, consultants, customer support teams
My take: Switched from Calendly, don’t miss anything, saved $96/year.
8. Fathom Analytics – Privacy-First Website Analytics
What it does: Website analytics without cookies, tracking scripts, or privacy concerns.
Why it made the list:
Google Analytics is powerful but overkill for most startups. It’s slow, requires cookie consent banners (annoying), and collects way more data than I need.
Fathom shows me:
- How many people visit
- Which pages they view
- Where they came from
- What they clicked
That’s all I actually need. The dashboard loads instantly and doesn’t require a PhD to understand.
What makes it different:
No cookie banners needed (GDPR compliant without annoying popups). Lightning-fast dashboard. Simple enough that I actually check it.
Pricing: $14/month for 100K page views
Best for: Privacy-conscious founders, European businesses dealing with GDPR, anyone overwhelmed by Google Analytics
My take: Finally understand my website traffic without spending 30 minutes navigating dashboards.
9. Plausible Analytics – The Other Privacy-First Option
What it does: Similar to Fathom, lightweight analytics without tracking.
Why both Fathom and Plausible made the list:
They’re nearly identical in features. Plausible has slightly cleaner design. Fathom has better uptime history. Try both, pick whichever interface you prefer.
I use Fathom on my main site, Plausible on side projects. Both get the job done.
Pricing: $9/month for 10K page views
Best for: Same as Fathom; privacy-conscious founders who want simple analytics
10. QuickBooks Online – Accounting That’s Actually Usable
What it does: Cloud accounting software that tracks income, expenses, and generates financial reports.
Why it made the list:
I tried Wave (free accounting software) for my first LLC. It’s fine for very simple businesses, but once I had multiple income sources and contractor payments, it became limiting.
QuickBooks Online handles:
- Bank account syncing (automatically imports transactions)
- Expense categorization (learns your patterns)
- Invoice creation and tracking
- Financial reports for taxes
- Integrations with Mercury, Stripe, everything
What makes it different:
It’s the industry standard. Every accountant knows how to use it. When tax season arrives, I export everything and hand it to my accountant. No confusion, no reformatting.
Pricing: $15/month (Self-Employed) or $30/month (Simple Start)
Best for: Anyone making real revenue, businesses with contractors or employees, founders who want tax time to be painless
My take: Started with Wave to save $15/month. Upgraded to QuickBooks after first tax season. Should’ve started here.
Should You Use All These Tools?
No.
Use the ones that solve problems you actually have. Ignore the rest.
If you’re a solo founder building an MVP, you need:
- LLC formation sorted
- Bank account
- Way to accept payments
- Basic accounting
That’s it. Four things.
Everything else can wait until you have revenue and real problems to solve.
My Honest Recommendation
Start with this stack:
- LLCtoolkitPro – Form your LLC correctly the first time
- Mercury – Bank account that doesn’t suck
- Stripe – Accept payments
- Wave (free) or QuickBooks ($30) – Track money
- Google Workspace ($12) – Professional email
Total cost: $42-$72/month
Add tools only when you have a specific problem they solve.
Most founders over-tool and under-execute. Don’t be that founder.
