The complete go-to-market platform for companies
selling into independent & international K-12 schools
Sell to the decision-makers at 45,000+ K-12 schoolsand turn replies into revenue.
A verified, global K-12 database that grows every month, campaigns written in your voice, and a pipeline built to close — one platform for the whole K-12 selling cycle, not a stack of disconnected tools.
Used by teams selling into schools worldwide
The whole system
Everyone else sells you a piece. We built the entire system.
Most teams selling into schools buy a data list that ages the moment it lands, then run it through a generic CRM that has no idea who is worth contacting or what to say. Big School is different: a live, verified schools database with AI that writes every email to the role and triages every reply. You sell faster, target more accurately, and scale outreach without adding headcount.
The usual way
- A bought data list — outdated before you send a single email
- A generic CRM — no idea who to contact or what to say
- Manual copy & chasing — written by hand, replies left unread
A living database, built into the platform
45,000+ schools and 419,000+ contacts, verified in-house and grown every month — wired directly into your sales system, not a static list you license and watch go stale.
Campaigns that write themselves — in your voice
Cortex AI drafts every email and follow-up from your Knowledge Hub — the product detail, messaging, and tone that make you sound like you — and shapes each one to the specific role and school it is going to.
Every reply handled, none missed
Responses are scored by intent and answered with an AI-drafted reply you approve — so a warm lead never goes cold sitting unread in an inbox.
A straight line to revenue
Turn any positive reply into a deal in one click, with the school record and full thread attached. One system carries every conversation from first touch to closed.
By the numbers
The data your competitors are still trying to build — verified, role-mapped, and ready to sell to.
45,000+ schools and 419,000+ contacts across the US, UK, Australia, New Zealand, Canada and international schools — all mapped by role so every campaign lands on the right person with accuracy, plus 3,000+ school groups mapped by hierarchy so you can reach an entire network in one move. It's included in your subscription and growing every month.
A living database, not a data set
Included in your subscription and always current — no annual repurchase, no stale contacts.
Every email verified for deliverability
Each address is checked for validity before it goes live — minimal bounces, less wasted send volume.
Mapped by role, school and group
Contacts are categorised across 23 role types inside the school and a further 16 at group level — so you target the right person, not just the right school.
Verified contacts
Every contact mapped to a specific role inside the school — 23 categories in all — so you reach the person who owns the decision, not a generic info@ inbox. We cover independent and international schools, plus a growing database of government schools across English-speaking countries.

Meridian International Academy
Plus a further 16 categories at group level — see the full data model and coverage map on the database page.
Group and school level
Sell to the group, not just the school.
Most school databases give you a list of schools. Fine if you sell one licence at a time. Useless when the decision is made two levels up.
Big School maps 3,000+ school groups — academy chains, multi-academy trusts, Catholic dioceses, international networks, state departments of education — and sorts their HQ contacts into 16 categories. Curate a campaign straight to that group database, and let Cortex AI personalise it to each function — at both the executives who decide at group HQ and the leaders who implement at every member school.
Dipont Education
Sorted into 16 group-level categories
Group HQ coverage is extensive, and every contact we hold is categorised into one of 16 functions — from Procurement and Group IT to Compliance and Curriculum — so you can target the exact decision-maker, not a generic head-office inbox.
Curate a campaign to the group database
Build a group-level campaign the same way you would at school level — filter by group type, size and category, then target only the HQ functions that buy what you sell.
Personalised by Cortex AI at both levels
Cortex AI writes to the audience you point it at — a Group Finance pitch reads differently from one to a member-school Principal, both drawn from your Knowledge Hub.
See the size of the prize, suppress in one move
A group's school count is on the record, so you know how many schools a network is worth before you write — and you can exclude a whole network in one action so existing clients are never contacted by mistake.
Group-level data on its own is just a spreadsheet. We make it something you can sell into.
Group HQ coverage is extensive, and every contact we hold is verified, categorised into 16 functions and kept current — so you can find the right decision-maker, launch a curated campaign, and let Cortex AI personalise it to hundreds of groups in the time it used to take to research one.
One supplier, every market
Most providers stop at a border.
Sell into the US and you buy one provider. Add the UK, international schools, Australia and Canada and that's four contracts, four data formats, four sets of gaps — and no way to run one campaign across them.
Who covers what
One subscription. One format. One campaign that crosses every border you sell across.

Personalisation
A form letter gets ignored.
A message about their school gets a reply.
A Principal can tell in one line whether an email was actually about their school or blasted to a list of ten thousand. Cortex AI writes from your product knowledge and what's known about that school and stakeholder — the role, the region, the group it belongs to — so every email reads like it was written for one recipient, because it was.
The list blast
DeletedSubject: An exciting solution for your school
Dear Sir/Madam,
I wanted to reach out to introduce our award-winning platform, trusted by thousands of organisations worldwide to drive efficiency and unlock value across their operations.
Would you be free for a quick call this week to discuss your needs?
Written by Cortex AI
RepliedSubject: Getting 1,200 devices ready before term at SUIS
Hi Wei,
With a cohort the size of Shanghai United International School, getting every student device imaged, enrolled and locked down before term usually eats most of your IT team's summer.
We helped two other IB World Schools in China do exactly that in under a week last August. Worth a 20-minute call before you start planning the new term rollout?
Written for the role, not just the name
A Business Manager and a Head of IT get pitches built around what each of them actually cares about — not the same email with a different first name swapped in.
Grounded in the school, not guessed
Region, school type, group affiliation and existing relationships all shape the message Cortex AI drafts — so it reads like you did your homework.
Approved in your voice
Every draft reflects your Knowledge Hub — your product, your tone, your positioning — so personalisation never means it stops sounding like you.
Personalised — and built to scale
At scale, not by hand
Cortex AI drafts every message individually, so one rep runs personalised outreach across thousands of schools — not the handful a person could write by hand.
Only to verified contacts
Every recipient is a real, role-mapped decision-maker whose email is checked for validity and deliverability first. No guesses, minimal bounces.
Targeted, never sprayed
Filtered by region, school type, role and group affiliation — so relevance holds even as the volume climbs.
The result: replies, not deletes. That's the difference between a 2% reply rate and one that actually fills a pipeline.
See how Cortex AI writesThe engine behind every message
Meet Cortex AI,
briefed on your business.
Cortex AI is Big School's internal engine. It doesn't improvise — it writes from your Knowledge Hub, a structured store of the facts, voice, and positioning of your business, and only ever inside the guardrails you set. A readiness score shows how complete it is, and you can read the exact grounding behind any reply. You stay in control of every word.
Load your Knowledge Hub, once.
Everything Cortex AI needs to sound like you — added a single time during onboarding, used everywhere after.
You brief Cortex AI. It writes.
Point it at a role segment and tell it what to lead on. Cortex AI is directable — not a black box.
Your brief to Cortex AI
“Write this for Business Managers at independent schools. Lead on budget control, keep it under 120 words, and avoid pricing until they reply.”
Campaign copy, written to a role
Target a role segment, brief Cortex AI on who it is for, and it writes the whole sequence to that audience — a Head of IT reads differently than an Admissions Director.
EDMs and broadcasts on-brand
Every broadcast pulls its facts, tone, and positioning from the Hub — so a newsletter sounds like your company, not a template.
Reply drafts with full context
When a reply lands, Cortex AI classifies the intent and drafts a response from the Hub and the exact message the lead sent. Edit it with Cortex AI or write your own — and set the confidence bar for auto-reply as high or low as you want, so it handles as much as you trust it to.
Subject: A quick thought on next year's software budget
Hi Sarah,
I hope you don't mind me getting in touch. Many business managers I speak with are being asked to plan for next year against a flat budget, and software renewals can be an easy thing to lose track of.
If it's helpful, we work with independent schools like {{school_name}} to bring scattered subscriptions into a single view — making it easier to see what's being spent and plan ahead with a little more clarity.
If you'd ever find it useful, I'd be glad to share what similar schools have found. There's no pressure at all — just let me know what works for you.
Warm regards, Alex
Nothing sends without you. Cortex AI drafts; you approve. Turn on auto-reply only when you trust it — and it still stays inside your Hub's guardrails.
See how Cortex AI worksHow it works
From first email to warm reply — one automated flow.
Not four disconnected tools you stitch together and babysit. One flow that targets, sends, follows up, and drafts every reply — handing your team conversations that are ready to close.
Target
Build your audience in minutes
Stack filters — country, curriculum, role, size — and a live counter shows exactly who you've matched. The database is already built, so there's zero list-building.
Compose
Build a multi-touch sequence
Mix emails and designed EDMs in one cadence. Give Cortex AI your angle and it drafts each touch from your Knowledge Hub — you approve before anything sends.
Automate
Send and manage replies
Sequences send from your own domain and run themselves. Every reply is scored by intent, drafted by Cortex AI, and non-responders roll to the next touch automatically.
Close
Hand off warm leads and measure
Turn a positive reply into a deal in one click — school record and full thread attached. Your dashboard ranks every step and flags the winner, so each sequence gets sharper.
It runs so your team doesn't have to
Leads that aren't ready stay in the cadence. The database adds new schools every month, and the reporting flags exactly what to change next — so your team only spends time on the conversations that convert.
Proof, not promises
Do the math on better outreach.
Same team, same hours. Big School changes what each send is worth by fixing the three things that quietly cap outreach into schools — who you reach, whether it lands, and whether it earns a reply.
Per-email personalisation
Personalising the email body lifts reply rates by a third. Cortex AI writes every send to the recipient and their school.
Reaching the whole buying group
Contacting several mapped stakeholders and following up beats a single email to a single contact — and Big School maps 23 roles per school.
List accuracy
Bought B2B lists rot fast; verified, continuously-refreshed data keeps you under the bounce threshold that protects deliverability.
Published benchmarks show personalised outreach converts to meetings at roughly 2–3x the rate of generic bulk sends. Big School gives one rep that personalisation across every school — without adding headcount.
Sources: Backlinko's analysis of 12 million outreach emails (personalised body copy lifts reply rates by 32.7%; reaching multiple contacts with a follow-up raises responses up to 160%); published B2B benchmarks for personalised versus generic outreach (roughly 2–3x meeting conversion) and contact-data decay (~22–25% per year). These are industry benchmarks applied to Big School's verified, role-mapped data — not guaranteed results. Actual performance depends on your offer, your list and your follow-up.
Capacity & cost
Cover more ground with the team you already have.
Opening a new market normally means hiring into it — a quarter of ramp before the first useful conversation. With Big School the data is already there for 181 markets, and the person you already employ runs the campaign this week. Consolidate a stack that typically runs $50,000 to $100,000 a year — or keep what you have and layer Big School on top.
Open a market without hiring into it
No data buy, no local list-builder. Coverage is already there for 181 markets.
One person covers what took a team
Every seat runs concurrent campaigns into different regions, each from its own domain.
New starters productive in week one
They inherit the database, sequences and Knowledge Hub instead of building from nothing.
Nothing walks out the door
When someone leaves, the messaging, sequences and pipeline stay behind.
And three of those are data licences you re-buy every year — yet even together they leave gaps, from group-level buyers to markets like Australia, Canada and New Zealand. Big School closes those gaps in a single subscription. See pricing
Happy with your stack?
You don't have to replace anything.
Keep the CRM your team already lives in. Sales and BD reps use Big School as the data and outreach layer on top — reaching more schools, more contacts and more markets than their current lists allow, then passing qualified, engaged prospects straight into the system they already report on.
More reach per rep
Verified contacts across 181 markets, not just the region your list covers.
No rip-and-replace
Runs alongside your CRM — hand off qualified prospects when they reply.
Faster prospecting
Cortex AI drafts and personalises the outreach so reps spend time on live conversations.
Reach net-new segments
Group-level buyers and markets your existing data simply doesn't reach.
Built to a standard
Compliant, secure, and transparent — by design.
Deliverability and data protection aren't add-ons — they're built into every campaign you send.
Built for compliant outreach
Contact data is handled on a lawful basis for professional B2B outreach, and the platform is built to support compliance with GDPR (EU/UK), CAN-SPAM (US), CASL (Canada), the Spam Act (Australia) and equivalents elsewhere. Unsubscribes are applied globally and immediately.
DKIM, SPF & DMARC validated
DNS health checks and email authentication records are verified at setup and monitored continuously — so your deliverability is protected from day one.
Your outreach, your domain
Every email leaves your own mailbox and domain via Google Workspace or Microsoft 365 OAuth, so your sender reputation is yours to keep. Large broadcasts run on dedicated infrastructure under a subdomain you control — never pooled with other senders.
Suppression list — always enforced
Upload your existing client list once. It is applied automatically across every campaign, forever — no manual filtering, no risk of emailing an existing client.
No setup fees, no lock-in
Minimum 6-month term. No annual contracts forced on you, and no auto-renewal. No setup fee. No module add-ons. Onboarding is included in every subscription.
Built-in warmup, no spam surprises
New mailboxes are warmed up automatically — sending and receiving real mail to earn ISP trust the right way. Sends are paced across the day and scaled to your bounce, spam, and engagement rates, reaching up to 150 a day within a few weeks.
