Territories and segments — how the market is carved up

Companies divide the market so reps don't trip over each other and effort matches opportunity.

Segments by customer size (boundaries vary; the logic is universal):

• SMB (small and medium businesses): high volume, small deals, short cycles, often sold remotely (inside sales — by phone/video rather than face to face). In this market: individual GP practices, small clinics, single academic labs.
• Mid-market: larger biotechs, private hospital groups, a university's central facilities. Deals in the tens of thousands to low hundreds of thousands; cycles of a few months.
• Enterprise: the largest organisations — top-20 pharma, NHS trusts and Integrated Care Systems (ICSs, the NHS's regional planning bodies), global CROs. Six-to-seven-figure deals, 6–18-month cycles, many stakeholders, formal procurement, and field sales (travelling to customers — the "~50% territory travel" line you'll meet in enterprise job adverts). Fewer, bigger, harder: an enterprise AE may close only 4–10 deals a year.

Know your numbers. "What deal sizes have you worked?" is a standard screening question — whatever figures your past work carries (project values, contract renewals, grants won), know where they sit on this scale and say so plainly.

Territories — who's allowed to sell to whom:

• Geographic patch: everything inside a boundary. An "Oxford, Wales & South West UK" account-manager patch or a "UK South" enterprise role are geographic territories — and the reason field sales is the one job family where where you live is part of your candidacy.
• Named accounts: instead of a map, a list — "these 30 pharma companies are yours". Standard in enterprise selling; the extreme case is one KAM per giant account.
• Vertical territories: carved by industry — one rep owns pharma, another NHS, another academia — used where the sales motion differs sharply by sector (selling to the NHS genuinely is a different craft from selling to pharma R&D).

Greenfield vs install base:

• A greenfield territory has no existing customers — all hunting, slow to first revenue, full prospecting freedom. A scale-up entering the UK and handing its first rep an empty patch is the classic case: expect a long build, and ask in interviews what pipeline, marketing support and reference customers ("has any UK trust deployed yet?") you'd inherit.
• An install base territory is rich in existing customers, tilting toward renewals and expansion — more farming, faster earnings. Territory quality is a huge, under-discussed determinant of earnings; sophisticated candidates ask "how was this territory constructed, and what did it produce last year?" before joining.

6. Full-cycle vs the pod model — and the vocabulary of survival

The pod model (the "Predictable Revenue" assembly line most scaled SaaS companies run): the funnel is split across specialists — SDRs prospect and qualify, AEs close, CSMs/AMs keep and grow — as in the handoff story in section 2. Strengths: focus, measurability, cheap top-of-funnel labour. Weakness: the handoffs themselves, where context and trust leak.

Voice from the field

"Making the field salespeople do cold calls means having your highest-cost (per hour) sales resource perform the lowest-value (per hour) activity."
— Aaron Ross, Predictable Revenue (2011)

The full-cycle AE does the whole thing personally: finds the prospect, qualifies, demos, closes, and often stays close after signature. Harder, more varied, and standard at startups — whose AE adverts usually say "full-cycle" explicitly. Why do startups run full-cycle?

1. Headcount economics: a pod (SDR + AE + CSM + SE) is four salaries; an early-stage company can afford one or two people who must cover the funnel end to end.
2. Learning speed: before product-market fit (the stage where a defined market reliably buys the product), the company is still discovering its pitch, pricing and ideal customer. An AE who hears the first cold call and the final negotiation feeds back richer signal than a segmented pod.
3. Coherence for the buyer: early customers are betting on a small company; one accountable human from first call to go-live builds more trust than three handoffs.
4. No install base exists — nothing to farm yet, so specialised farmers make no sense.

Field note

"Full-cycle" in a job advert deserves one honest translation check. Sometimes it means the deliberate startup design described above; sometimes it means "we have no SDRs, little marketing and no inbound — you will source everything you close". The difference is discoverable in interview: ask what share of the current pipeline is inbound versus rep-sourced, and what the founders closed themselves before hiring you. Self-sourcing everything is workable, but it should be priced into the quota and the ramp.

A case study in quota mechanics. One YC-backed startup automating NHS GP-practice admin made a gift of a case study: its 2026 AE adverts quoted quota mechanics like 10 practices live per week at a 70% demo-to-sign conversion — an unusually transparent example worth studying of an activity-anchored quota with an explicit win-rate assumption, in a high-velocity SMB motion (thousands of GP practices, short cycles) even though the buyer is the NHS.

Contrast a clinical AI scale-up selling radiology software — a handful of enormous NHS trust/ICS deals a year — and you have the two poles of NHS selling, sometimes advertised in the same week.

Three last pieces of vocabulary, offered honestly:

Ramp

The grace period before a new rep carries full quota — typically 3–6 months, up to 9–12 in enterprise — often with reduced targets and a draw. Sales-cycle length dictates it: you cannot close a 9-month deal in month two. Ramp schedule and draw are negotiable; for anyone entering the sector without a sales track record, a realistic ramp is protection to secure explicitly.

Pipeline reviews and forecast calls

The weekly operating rhythm of sales life — walking through every open deal ("what stage, what's next, when will it close, what could kill it?"). Interviewers sometimes probe your appetite for this cadence ("how do you like to be managed?").

PIP — Performance Improvement Plan

The formal process for underperforming reps — typically 30–90 days of specified targets, with dismissal the usual outcome if unmet. The honest version: in many high-growth sales cultures a PIP functions less as rehabilitation than as the documented exit path. In the UK, employment law makes the fast PIP-and-out harder than the US-flavoured folklore suggests — with qualifying service a PIP sits inside a formal capability procedure — but the cultural signal it sends is the same.

This is the flip side of the earning potential: sales puts your output on a dashboard everyone sees, updated weekly. Knowing this — and being able to say soberly why you still want a quota anyway — reads as maturity, not naivety. The question will come; prepare the answer before the interview does.
