A lean founder tool stack: what you need in your first 90 days

Tools are named as well-known public examples only. Startup Roof has no partnership with any of them and receives nothing for mentioning them. Plans and features change; check each provider's own site.

It's easy to spend the first weeks of a startup signing up for software. Every tool promises to save time, and many have free plans, so the stack grows quietly until you're paying for overlapping subscriptions nobody uses.

A lean stack does the opposite: the fewest tools that cover what you actually need now, chosen so they work together and can grow with you. This guide sets out the categories a new UAE startup typically needs in its first 90 days, with well-known examples, and the questions to ask before adding anything.

Principles first

1. Start from the job, not the tool. Write down what you need to do this month (send proposals, track leads, invoice clients), then pick a tool.
2. One tool per job. Two project management tools means neither is up to date.
3. Prefer suites early. An email, calendar and documents suite covers a surprising amount.
4. Use free plans honestly. They're great for testing. Check their limits before your whole team depends on one.
5. Own your data. Make sure you can export everything, and that company accounts are owned by the company, not one founder's personal login.
6. Review every quarter. Cancel what isn't used.

The core categories

1. Domain, email and calendar

A professional email address on your own domain builds trust with customers, banks and authorities. Suites such as Google Workspace and Microsoft 365 bundle email, calendar, video calls, documents and storage. Choose one and use it for everything.

Tip: some programmes require a company email domain that matches your website (Google's startup cloud programme does, for example); see our guide to free cloud credits for startups.

2. Documents, notes and a company wiki

You need one place for plans, meeting notes, processes and decisions. Your suite's documents tool may be enough. Tools such as Notion combine notes, wikis and simple databases. Whichever you choose, create a simple structure on day one: Company, Customers, Product, Finance, Legal.

3. Team communication

For a team of two, a group chat may be enough. As you grow, a dedicated tool such as Slack or Microsoft Teams (part of Microsoft 365) keeps work conversations searchable and separate from personal messages. Agree simple rules: which channel for what, and when to use a call instead.

4. Tasks and projects

A visual board such as Trello, or the task features in your wiki tool, is usually enough early on. What matters is the habit: every task has an owner and a date.

5. Customer conversations and CRM

Your first customers will come from conversations, so track them. A spreadsheet works for the first 20 contacts. After that, a CRM with a free tier, such as HubSpot CRM or Zoho CRM, helps you track every lead, conversation and next step as you grow.

In the UAE, many customers prefer WhatsApp. A WhatsApp Business account separates business from personal chats and lets you set up a business profile and quick replies. Get consent before sending marketing messages.

6. Scheduling

A booking link, from a tool such as Calendly or your suite's built-in booking pages, removes the back-and-forth of arranging calls. Useful for customer interviews and sales calls.

7. Design and brand

Tools such as Canva let non-designers create social posts, decks and simple graphics on brand. Figma is widely used for product and interface design. Set up your logo, colours and fonts once, and reuse them.

8. Website

A simple, fast website with a clear description, contact details and a way to get in touch is enough to start. Many website builders exist. Pick one your team can update without a developer, and connect it to your domain.

9. Finance: invoicing, bookkeeping and payments

This is the category not to improvise:

• Accounting and invoicing. Use accounting software that can produce tax-compliant invoices and reports once you register for VAT. The FTA sets the requirements for tax invoices and record-keeping; see our VAT guide and FTA: VAT.
• Bookkeeping from day one. Corporate tax filing applies even when no tax is due; clean books make it far easier. See our corporate tax guide.
• Payments. If you take card payments online, use a licensed payment provider that supports UAE businesses. They'll ask for your licence and business bank account.

10. Passwords and security

A team password manager, two-factor authentication on every important account, and company ownership of key logins (domain, email, bank, social accounts) prevent the most common early disasters. Keep a simple list of which accounts exist and who has access.

Questions to ask before adding any tool

• What job will it do, and what are we using for that today?
• Who owns it, and who will keep it up to date?
• What happens when we outgrow the free plan?
• Can we export our data?
• Where is data stored, and does that matter for our customers? The UAE has a federal personal data protection law, so treat customer data with care.
• Does it connect to what we already use?

A sample 90-day stack

Need	Simple choice
Email, calendar, docs, storage	One productivity suite
Wiki and notes	Suite docs or a wiki tool
Team chat	Suite chat or a dedicated chat tool
Tasks	One board tool
Customers	Spreadsheet, then a free-tier CRM; WhatsApp Business
Scheduling	A booking-link tool
Design	One design tool with brand kit
Website	A builder your team can update
Finance	Accounting software + licensed payments
Security	Password manager + 2FA everywhere

That's around ten tools, several of which may come in one suite.

Setting up your stack in one afternoon

You don't need weeks to set this up. A practical order:

1. Buy your domain and set up your email suite on it. Create shared addresses such as hello@ or accounts@ that forward to the right people.
2. Create a company password manager and store every new login in it from the start.
3. Set up your wiki with the five top-level sections, and write a one-page "how we work" note: which tool for what.
4. Create your CRM or pipeline sheet with columns for contact, source, last conversation and next step.
5. Connect your accounting software to your business bank account once it's open, and set a monthly reminder to reconcile.
6. Turn on two-factor authentication everywhere, and record who owns each account.

Write the stack down in your wiki, with the owner of each tool, so new team members can get started on day one.

Common mistakes

• Signing up with personal accounts. When a founder leaves, the company loses access. Use company accounts.
• Paying annually too early. Use monthly plans until a tool is clearly essential.
• Tool-hopping. Switching tools every few weeks costs more time than any tool saves.
• Ignoring finance tools until the first VAT return or corporate tax filing.
• No offboarding. When someone leaves, remove their access the same day.
