The First IT Systems Every Startup Should Build
A hand beneath a collection of connected technology icons, representing the core IT systems and digital infrastructure a growing startup needs to build and manage.
Most Startups Don’t Design Their IT. They Accumulate It.
The founder buys a domain and creates Google Workspace. Slack gets added a few days later. Someone signs up for a password manager. The first employee receives a laptop ordered directly from Apple. Sales adds a CRM. Engineering starts using GitHub. Marketing connects a few applications to Google Drive. Someone tries an AI tool on a personal account and never mentions it.
Individually, every decision is reasonable.
The problem appears later, when those individual decisions have quietly become the company’s IT infrastructure. No one ever decided how the pieces were supposed to work together.
At five people, that barely matters. Everyone knows everyone, employees ask the founder when they need access and there are only a handful of devices and applications in play.
At thirty, informal IT stops holding.
The goal is not to recreate the IT department of a 5,000 person enterprise. A growing software or AI company needs something much simpler: a small number of systems that establish identity, ownership, security, consistency and recoverability before the organization becomes difficult to manage.
Here are the ten I would prioritize, in the order I would build them.
1. Identity and Access Management: Decide How People Prove Who They Are
An identity system is the record of who works at your company and what each person is allowed to reach. It is the first IT system to build because almost every other system depends on it.
For most startups, this begins with Google Workspace. But creating name@company.com accounts is not the same as having an identity system.
Your identity layer should establish who is an active employee or contractor. What role and department they belong to, which groups they belong to, which applications they should access. Who holds administrative privileges, how authentication is protected and what happens to that identity when they leave.
Get identity right and later processes get easier by default. Onboarding becomes assigning someone to the correct groups instead of manually granting twenty permissions. Offboarding becomes removing one controlled identity instead of trying to remember every application that person ever touched.
Google Workspace supports the structures this requires — Google Groups, Organizational Units, delegated admin roles, and enforced 2 Step Verification. Those controls are far more valuable when they are established before an account structure becomes inconsistent.
The question is not “does this person have an account?” It is:
Does this person’s identity automatically give them the right access and only the right access?
2. Authentication: Build Login Security That Doesn’t Depend on Memory
Authentication is how your company verifies that a login attempt is really the employee it claims to be. For a startup, that means a company managed password manager, unique credentials everywhere and MFA enforced on anything that matters.
Verizon’s 2026 Data Breach Investigations Report marked a genuine shift: for the first time in the report’s history, vulnerability exploitation (31% of initial access) overtook stolen credentials. It would be easy to read that as credentials mattering less.
They don’t. Verizon found credentials involved in 39% of all breaches once the full attack chain is considered, and reported infostealer malware present on 54% of devices appearing in initial access broker logs. The marketplaces where stolen corporate logins are packaged and sold. Verizon also found that half of ransomware victims had a credential or infostealer event within 95 days before the attack.
Credentials didn’t stop being the problem. They stopped being the first step.
The practical takeaway for a startup is unchanged: employees should not be expected to remember a different strong password for every application.
A working authentication system includes a company managed password manager, unique passwords for every service, MFA enforced on important accounts, stronger authentication for administrators. As well as documented account recovery and passkeys or hardware security keys where practical.
NIST’s current guidance (SP 800-63B-4, finalized in 2025) reflects the same shift. Rather than complex composition rules and mandatory periodic resets. NIST emphasizes password length, screening candidate passwords against known compromised lists, password manager compatibility and MFA.
The password should become one component of a system, not the system.
3. Employee Lifecycle Management: One Process for Joining, Changing Roles, and Leaving
Employee lifecycle management is a single documented process covering everything IT does when someone joins the company, changes roles or departs.
Most early stage companies treat onboarding and offboarding as separate administrative events. They work far better as one lifecycle.
Before the employee starts: create required accounts, assign hardware, establish role based access and prepare the device.
On day one: enroll MFA, provide application access, confirm password manager setup, verify the employee can actually work.
When responsibilities change: review existing access rather than simply layering on more permissions.
During employment: perform periodic access reviews and verify devices remain compliant.
When the employee leaves: suspend accounts, revoke SaaS access, recover equipment, transfer company data and verify the process was completed.
This is the difference between treating every hire as a unique IT project and building something that supports repeated hiring.
At ten employees, it saves a few hours. At fifty, it determines whether onboarding and offboarding remain manageable at all.
4. Device Management: Know Every Laptop Before the Laptops Multiply
Device management means knowing which employee holds which machine, how it is configured and whether it is secure. Also if it’s enforced centrally rather than requested individually.
The first few startup laptops are easy to track. You know who has each one because you personally ordered them. That stops scaling faster than founders expect.
Eventually you need to know which employee has which device. This includes its serial number and model, purchase date, warranty status, OS version, whether disk encryption is enabled. As well as whether security software is running, updates are current and what happens to the machine when that person leaves.
That inventory is the beginning. The next step is centralized management through an MDM or endpoint management platform, where encryption, screen locks, update policy, and security configuration are enforced rather than requested.
CISA’s small business guidance consistently returns to the same fundamentals: keep software updated, protect accounts with MFA, maintain backups and control administrative access. Verizon’s 2026 findings underline the update half of that. Exploitations of edge devices and VPNs jumped from 3% to 22% of initial access in a single year. The median time organizations took to fully patch a known exploited vulnerability rose to 43 days.
The specific tool matters less at first than the principle:
Company devices should have known ownership, known configuration and a defined lifecycle.
5. Company Data Storage: Give Files an Owner That Isn’t a Person
Company data storage means company information lives in company controlled locations, owned by the organization rather than by whichever employee created the file.
When a startup is small, files end up everywhere. A founder’s My Drive. Someone’s Downloads folder. A Slack attachment. A developer’s laptop. An employee created Dropbox account.
That works until the person who owns the file leaves or until nobody can find the current version.
In Google Workspace, Shared Drives make the critical distinction: files belong to the organization, not the individual user. When someone departs, the work stays.
Your data system should answer where company documents should be stored, who owns each Shared Drive, who can share externally, which information should not live on employee laptops. What has to be retained and what happens to company data when someone leaves.
You do not need an enterprise information governance program. You need one clear default:
Company information belongs in company controlled systems.
6. SaaS Inventory: Know What Software You Actually Run
A SaaS inventory is a maintained record of every application the company uses, who owns it, who administers it, what it costs and what data it touches.
Software sprawl never announces itself. An employee buys a design platform. Another team signs up for project management. Someone connects an AI application through Google OAuth. Finance discovers a subscription six months later.
Zylo’s 2026 SaaS Management Index covering more than 40 million licenses and $75 billion in spend found organizations leave an average of 36% of SaaS licenses unused. It also found expense based SaaS spend, meaning software bought on employee cards rather than through procurement, up 267% year over year. 77% of IT leaders reporting they had discovered AI features or applications running without IT’s awareness.
For AI companies specifically, this is not a hypothetical. Verizon’s 2026 DBIR found that among employees who use AI tools regularly, roughly two thirds were doing so through non-corporate accounts. Company data moving through identities the company does not control and cannot revoke.
A basic inventory records the application name, purpose, internal owner, administrator, current users, cost, renewal date, authentication method, the data it can access and what has to happen at offboarding.
That does more than control spend. It gives you an answer when someone asks:
What systems does this company actually depend on?
7. Account Recovery and Emergency Access: Plan for the Day You’re Locked Out
An emergency access plan documents who holds critical administrative accounts, how each one is recovered and what happens if the person holding it is unavailable.
This system is easy to ignore, because you rarely need it. Until you desperately do.
The founder’s phone disappears while traveling. The only Google Workspace Super Admin gets locked out. The person who controls the domain registrar leaves unexpectedly. Nobody can reach the password manager administrator account. An MFA security key is lost.
Those are not password problems. They are business continuity problems.
Every startup should document its primary administrators, backup administrators, recovery methods and the location of emergency recovery codes. This should include domain registrar ownership, password manager recovery, billing ownership, emergency authorization, physical security keys and what happens when a critical administrator leaves.
Then test it before there is an emergency.
A recovery procedure that has never been tested is still partly an assumption.
8. Backup and Restore: Answer “Could We Actually Get It Back?”
Backup for a cloud first startup means knowing, for each business critical system. Knowing what the provider retains, for how long and what additional protection you need to restore from a bad day.
Cloud software creates the impression that backup is someone else’s problem. Sometimes it is. Often it isn’t and the distinction is worth knowing before you need it.
Start by identifying where data loss would materially affect operations: email, shared documents, source code, customer information, finance records, HR records and any critical SaaS platform. Then determine what each provider actually protects, how long it retains it and whether additional backup is required.
CISA recommends maintaining backups of important data and regularly testing recovery as a core resilience practice. The testing half is the part most startups skip.
The useful metric is not “do we have backups?” It is:
Could we restore what we need, in the time we’d need it?
9. IT Documentation: Stop Depending on One Person’s Memory
IT documentation is one controlled location holding the operational knowledge required to run the company’s technology. Think administrators, vendors, processes and recovery steps.
Startups usually have documentation. They just don’t know where it is.
A Wi-Fi password in Slack. Domain registrar details in the founder’s notes. A hardware spreadsheet owned by Operations. Onboarding instructions in Notion. Vendor contacts buried in an inbox.
The purpose is not to document every technical detail imaginable. It is to prevent critical operational knowledge from living in one person’s memory.
At minimum, write down who holds administrative access to each system and who an employee should contact when something breaks. Add the assets: device inventory, key vendors and the internal owner of every SaaS application. Then the repeatable parts such as onboarding, offboarding, emergency recovery, your important security settings and the handful of problems that come up often enough to have a known fix.
This matters most at the exact moment it’s hardest to create: when outside IT support, a first internal IT hire or a new operations leader enters the picture. They should not need an archaeological expedition to understand how the company works.
10. IT Support Channel: Give Employees One Place to Ask for Help
An IT support channel is a single defined route for technology requests, so problems are tracked and resolved rather than absorbed by whoever happens to be free.
Without one, IT requests arrive everywhere. Slack messages. Texts. DMs. Emails. A founder getting tapped on the shoulder mid meeting.
The cost isn’t only interruption. When requests never land in one place, they can’t be counted. So a problem that’s surfaced four times never gets recognized as recurring, nothing gets prioritized against anything else and nobody can say whether IT takes an hour to respond or three days. An outage hitting six people arrives as six unrelated complaints.
A startup does not need a sophisticated enterprise help desk on day one. It needs a clear answer to “where do I go when something isn’t working?” Eventually a ticketing or managed help desk system where requests are tracked, assigned, documented and resolved consistently.
Most importantly, employees stop depending on whichever technical person happens to be available.
