The private networking app for professionals who work for themselves — even when they work for someone else.
No business cards. No LinkedIn requests. No begging colleagues for referrals. Just a word.
Choose a secret word — anything you like. This is the key your clients use to find your number. Only you decide who gets it.
When you meet someone you want to stay connected with, simply tell them your secret word. That's the entire introduction.
They open the app, enter your word, and your phone number appears. Instant. Private. Completely on your terms.
You're good at what you do. The last thing you need is your employer finding out you're building a client list on the side. Sidedoor gives you a completely private channel — no social media, no paper trail.
Your hairdresser moved salons. Your personal trainer went independent. Your physio set up their own practice. If they gave you a word, you can find their number — no middlemen, no expired links.
Clients use the app for free — just create an account and look up any professional who shared their secret word. Professionals pay £2/month for the full toolkit.
No data harvesting. No recommending you to strangers. The word stays between you and them.
Hairdressers, trainers, coaches, physios, tutors, decorators — if they use Sidedoor, you can reach them.
Sidedoor doesn't announce itself. It lives quietly on your phone under whatever contact name you choose — and it can disguise its icon as something completely unremarkable.
You choose what name the contact uses — Mum, Dad, a friend's name, anything. If anyone scrolls your phone, they'll see a contact — not a secret networking app. No raised eyebrows. No awkward questions.
Choose your disguise icon
Simple two-tier model. Clients are free. Professionals get the full toolkit for £2/month.
Find any professional who shared their secret word with you. Private, direct, no middleman.
Your private channel, fully protected. Everything a professional needs to stay hidden from their employer.
Yes. Sidedoor doesn't post anything publicly, doesn't connect to LinkedIn, and doesn't appear anywhere that would identify you as running a side business. The app is disguised in your contacts under a name you choose, and can wear a generic icon. There's no social profile, no public listing, and no way for anyone to discover you're using it unless you tell them your word.
Instantly, the old word stops working for everyone. Anyone who tries the previous word will get nothing — your number is completely shielded. You simply tell your current clients your new word when you see them next. This is especially useful if you move to a new employer or want a clean slate.
Technically yes — a word can be passed on. But you're in control: if you find unexpected contacts coming through, you can change your word at any time. Think of it like a password — share it wisely, change it when needed. Most users treat it as an informal referral system.
Yes — clients sign up with a free account (just email and password). There's no subscription or payment required for clients. Your account keeps your lookup history private and lets you message professionals directly in the app.
Anyone who builds personal relationships with clients in their job — and wants to maintain those relationships privately. Hairdressers, personal trainers, physios, massage therapists, tutors, coaches, interior designers, tradespeople, financial advisors, and anyone else who works with people directly. If you'd rather your clients contacted you personally rather than going back through an employer or platform, Sidedoor is for you.
Through the App Store or Google Play, exactly like any other subscription. No hidden retention flows, no "are you sure?" obstacles. Cancel in two taps. If you rejoin later, you'll get a new word and start fresh.
Download free. Be ready the next time you meet someone worth keeping.
Good. Now pick your word, share it with the right people, and stay invisible to everyone else.
