What a conference dossier is, and how it differs from a lead list

A lead list is a set of names that match a filter. A conference dossier is a set of reasons to walk up to a particular person at a particular meeting. The first is an input to prospecting; the second is the prospecting, already done.

Both come as a file, and both cost money, so they get compared. They are not the same purchase, and buying one when you needed the other is the usual way a conference budget disappears.

What a lead list is

A list is the output of a filter: institution, field, seniority, sometimes a keyword from a publication. It is broad by design, it is the same list for everyone who buys from that vendor, and it is priced per contact. It is useful when your problem is coverage: you know what you want to say, you just need enough people to say it to.

Its limits are also structural. A filter cannot tell you whether a researcher is about to buy anything, or whether they already own your competitor's instrument, or whether the person who signs is the postdoc or the head of the core facility. And every one of your competitors can buy the same list.

What a conference dossier is

A dossier is built for one meeting and one company's product lines. It contains:

• ·The researchers presenting work that your products are built for, not everyone in the field.
• ·What each one has been funded for, what they are working on now, and why that makes them worth your team's time this year.
• ·Where and when they will be: the session, the day, the board.
• ·The labs around them: who they publish with, and who else is worth a visit while you are already there.
• ·A plan for the floor, with the sessions that clash already resolved.

It is finished before the meeting, it is different for every company that orders one, and it is priced per meeting rather than per name, because the work is the judgement rather than the volume.

The practical difference

A team with a list arrives with 2,000 names and no way to rank them, so it ranks them by who is nearest to the stand. A team with a dossier arrives with 200 names in an order, a reason for each one, and a map.

That difference shows up in the follow-up more than in the week itself. A conversation that started with "your grant last year was for exactly the problem our system solves" is a conversation you can continue in October. A badge scan is not.

When a list is the right thing to buy

It genuinely is, sometimes:

• ·You are running a broad campaign rather than attending a meeting.
• ·You need volume for an email sequence and accept the conversion rate that comes with it.
• ·Your product sells to almost every lab in a field, so filtering adds little.

If any of those is true, buy the list. It is cheaper and it will do the job.

When a dossier is

• ·The meeting is the single largest line in your sales budget for the year.
• ·Your instrument is specific enough that only a fraction of the field could ever buy it.
• ·Your team is small enough that the week is decided by who they spend it with.

A booth at a large scientific meeting costs a mid-five-figure sum once travel and stand build are counted. The question is not whether preparation is affordable. It is whether it is affordable to send four people to stand next to a screen for four days and find out afterwards who was there.
