IT Support for Startups London
IT Support for Startups in London
Flexible IT support, cloud administration, automated device management and robust cyber security built specifically for scaling, funded teams — without the cost or complexity of hiring an internal IT manager.
Engineered for Modern, Cloud-First Teams
We work with operational startups that value security, stability, and speed. We establish solid IT baselines so your team can focus on growth.
Funded Teams
Once you secure your Seed or Series A round, investor due diligence and client contracts require professional IT foundations. We implement controls that satisfy compliance audits immediately.
Fast-Scaling Startups
Adding 5, 10, or 20 people in a quarter? We automate device enrollment and account creation to make onboarding instant, repeatable, and completely secure.
SaaS & Tech Agencies
Startups running on Slack, Notion, GitHub, and Figma need centralized identity management. We integrate your SaaS tools with your main directory for single-sign-on protection.
The Growing Pains We Solve
Stop wasting founder time on IT troubleshooting.
In the early days, setting up laptops or resetting passwords falls on founders or office managers. But as you grow past 5 to 10 people, this ad-hoc approach becomes a major bottleneck. Weekends spent configuring MacBooks or worrying about security gaps are hours stolen from growing the business.
Threewaves establishes mature IT operations. We replace manual configurations with automated enrollment, secure your email domains to prevent spoofing, and structure your cloud storage so company data remains organized and secure.
Typical Startup IT Gaps We Remediate:
- Admin Rights Chaos: Team members running as local administrators on their laptops, bypass security updates, or install unauthorized software.
- Data Sprawl: Sensitive client documents stored in personal Google Drives or shared via public links instead of restricted Shared Drives.
- Offboarding Overlooks: Former staff and freelancers retaining active access to Slack, GitHub, or company files weeks after they leave.
- Weak Authentication: Lack of enforced Multi-Factor Authentication (MFA) and conditional access on critical cloud systems.
- Centralized device management to secure and monitor every endpoint.
- Professional onboarding and offboarding workflows.
- Enterprise-grade email security (SPF, DKIM, DMARC) out of the box.
- Zero vendor lock-in with monthly agreements tailored to startups.
Your Complete Startup IT Layer
A comprehensive set of services designed for cloud-first, hybrid teams.
Google Workspace & Microsoft 365
We manage, secure, and monitor your cloud directories. We restructure chaotic file systems into clean, permissioned Shared Drives or SharePoint libraries. Learn more about our Google Workspace support and Microsoft 365 support.
Mac, Windows & Linux Fleets
We are fluent in mixed operating system environments. We manage MacBooks and Windows PCs remotely using native Mobile Device Management (MDM). Learn more about our specialized Mac IT support in London.
Secure Onboarding & Offboarding
New hires receive a pre-configured device shipped straight to their door, ready to work. When employees leave, we instantly revoke cloud credentials, lock the device, and arrange safe retrieval.
Device Management (MDM)
We remotely deploy security policies, enforce local hard drive encryption (FileVault/BitLocker), and patch software. No manual setups, no configuration drift, and no unmanaged endpoints.
Cyber Security Basics
We implement the essentials: MFA enforcement, Conditional Access, Endpoint Detection & Response (EDR), and security awareness. Read about our cyber security for London businesses.
Cloud Backup & Disaster Recovery
Google and Microsoft do not back up your data against user error or ransomware. We provide independent, automated daily backups for your email and documents. Read about cloud backup and disaster recovery.
Outsourced Startup IT vs. Hiring Internal IT
Many startups wonder when to hire their first full-time IT manager. While a dedicated employee makes sense once you reach 80–100 people, doing so too early is an expensive luxury. A single internal hire introduces a single point of failure (holiday, sick leave, departures) and rarely covers the full spectrum of technical expertise required (helpdesk support, security compliance, vCIO strategy).
Hiring an Internal IT Manager
- Average salary £45k–£60k+ plus overheads.
- Single person — limits helpdesk response speed.
- Gaps in specialist skills (e.g. advanced cyber security).
- No coverage during holidays or sick leave.
Threewaves Managed IT
- Predictable, flat-fee pricing starting at a fraction of the cost.
- A team of engineers answering tickets fast.
- Access to senior consultants, MDM experts, and security analysts.
- Continuous coverage, 52 weeks a year.
Working with Threewaves gives you an outsourced IT department that scales with your growth stages. We handle daily support and security baselines, and we can hand over a perfectly documented, standard IT infrastructure to your first internal IT hire when the time is right.
Simple Setup
How We Set Up Startup IT
We know startups move fast. Our onboarding process is designed to get you secure and supported with minimal noise or administrative friction.
1. Discovery & Review
We start with a brief review of your current setup (devices in use, cloud platforms, SaaS tools). We identify urgent security issues, compliance gaps, and licensing waste without charging you a penny.
2. Deployment & Securing
We connect your existing devices to our MDM platform, enforce MFA and local encryption, configure independent backups, and establish secure shared folders. We complete the setup in the background so your team isn't interrupted.
3. Scaling & Ongoing Support
Your team gets direct access to our fast-response helpdesk. As you grow, we take care of purchasing and provisioning new laptops, creating new user accounts, and offboarding departing freelancers securely.
Frequently Asked Questions
Common questions about IT support for London startups.
When should a startup outsource IT support?
Startups should outsource IT support once they reach roughly 5-10 people, or as soon as they secure funding. At this stage, founders and office managers should no longer spend weekends setting up laptops or troubleshooting email access. Outsourcing establishes secure, professional foundations early, ensuring compliance for client audits and investor due diligence.
Can you support both Google Workspace and Microsoft 365?
Yes, we support both platforms. Whether you are a cloud-first team built entirely on Google Workspace, a traditional Microsoft 365 environment, or run a hybrid setup, we take care of licensing, email routing, Shared Drives/SharePoint structures, and identity protection.
Do you support Mac and Windows teams?
Absolutely. We specialize in cross-platform environments. We use Apple-native Mobile Device Management (MDM) platforms for macOS, and modern cloud management tools for Windows. We also support Linux users, ensuring all devices are secured, updated, and integrated with your company network.
Can you help with onboarding and offboarding staff?
Yes, this is a core part of our service. We configure zero-touch deployment so new hires receive a pre-configured device delivered to their door. On their first day, they just open the lid and log in. For offboarding, we immediately revoke access across Google Workspace, Microsoft 365, and SaaS tools, lock the device remotely, and retrieve it safely.
Can you improve our cyber security before funding, audits or client due diligence?
Yes. We specialize in aligning startups with cyber security frameworks like Cyber Essentials. We implement essential controls like MFA, Endpoint Detection and Response (EDR), local hard drive encryption, and secure password managers. This satisfies security questionnaires from corporate clients, insurers, and venture capital due diligence.
Do startups need separate backup for Google Workspace or Microsoft 365?
Yes. While Google and Microsoft ensure their infrastructure is resilient, their service agreements do not protect against human error, malicious deletion, or third-party app corruption. We provide automated, daily cloud-to-cloud backups stored independently in UK data centers to ensure recovery.
Can you work with our existing tools and SaaS stack?
Yes, we integrate with your existing cloud-first tools and SaaS stack. Rather than forcing you into rigid systems, we manage access, monitor security logs, and ensure tools like Slack, Notion, GitHub, and Figma are integrated securely with your main identity provider.
