A CDMO selling manufacturing capacity and an instrument company selling to academic labs may both need leads. They probably do not need the same prospect list, buyer titles or opening conversation. Start there before comparing appointment counts.
How we chose the firms
We reviewed public service pages and work examples available on 7 October 2026. Each firm needed an active life science offering that includes prospecting, qualification or outsourced business development. We selected different delivery models a CRO, CDMO, scientific supplier or life science software company might consider. The case data cannot support a performance ranking.
Published campaign results come from the firms' own sites. A booked meeting, a qualified lead, an opportunity and a signed contract describe different stages, so the numbers below should not be compared as if they were the same result.
The six firms at a glance
- Accel Bio: phone-first account research, qualification and meetings for scientific suppliers.
- Succession: email and LinkedIn prospecting, with an emphasis on scientific messaging and deliverability.
- Outbound Pharma: targeted business development for CDMOs, CROs and other pharma-facing suppliers.
- Corstrate: fractional business development that can carry sponsor conversations further into the pipeline.
- EKG Sales Associates: phone-led prospecting to researchers, with webinar and presentation support.
- North Star Scientific: multi-channel outreach, trade-show representation and optional full-cycle sales.
1. Accel Bio: phone-first meetings with scientific buyers
Accel Bio assigns a researcher, sales development representative and campaign manager to identify relevant accounts, call prospects, qualify interest and schedule meetings. The offer is aimed at CDMOs, CROs and other suppliers selling to biotech and pharma teams. It fits a company that knows the type of buyer it wants but needs more live conversations with those accounts.
In its QuanMol case study, Accel Bio reports 19 booked meetings during the first three months. If you evaluate the service, ask how the account list is built for your scientific niche, what qualifies a meeting, and how booked and held meetings are reported. A separate brand or inbound-content partner may still be useful if buyers cannot yet understand the offer from your website and sales materials.
2. Succession: email and LinkedIn outreach for life science companies
Succession manages list building, messaging, email infrastructure and LinkedIn outreach for companies selling into biotech and pharma. Its service page describes a three-week setup, regular message testing and a month-to-month agreement. The wider company offering also includes sales training and AI workflow work.
That model suits a team that wants outsourced prospecting and wants to see the campaign data as it runs. Ask how Succession would build a list for your particular modality or product, which outreach channels would actually be used on your account, and what makes a reply eligible for a sales meeting. Its lead-generation page emphasizes email and LinkedIn, so a buyer who wants substantial calling should clarify the phone component.
3. Outbound Pharma: CDMO and CRO business development
Outbound Pharma works across contract development, manufacturing, research and other life science services. Its case library includes several CDMO and CRO programs. In a 12-week campaign for a Canadian specialty CDMO, the firm reports seven qualified meetings. The target list reflected the client's non-sterile liquid, topical and nasal formulation capabilities; the campaign also used conference audiences.
The case gives a prospective CDMO buyer something specific to examine: the service fit behind the target list, the buyer roles reached and what happened after the meetings. Ask Outbound Pharma to distinguish meetings booked from meetings held and to show how it would qualify a company whose drug program matches your actual capacity.
4. Corstrate: fractional business development for long sales cycles
Corstrate combines account mapping, email, LinkedIn, event follow-up and fractional business development for CROs, CDMOs and other life science providers. Its model can reach beyond first meetings into proposal work. In a multi-year program for a specialist imaging core lab, Corstrate reports 68 qualified opportunities across 50 new accounts and $27.6 million in sourced pipeline value.
Those figures describe a longer engagement and later pipeline stages, so they are a poor shortcut for comparing monthly appointment-setting vendors. Corstrate is worth a closer look if your team needs senior business development support as well as prospecting. Ask which stages the firm owns, who handles sponsor calls and how it defines an opportunity before assigning a value to it.
5. EKG Sales Associates: researcher-focused calling
EKG Sales Associates describes phone contact as a core part of its life science lead-generation service. It also helps arrange webinars, conference calls and on-site scientific presentations, and can follow up leads your team already has. Its site carries named testimonials from companies including Cellecta, Pressure BioSciences and HTG Molecular.
EKG looks especially relevant to suppliers selling research tools or products into laboratories, where reaching a working scientist matters as much as reaching a procurement title. Ask how recently its contacts in your segment were verified, how the team learns a technical product and what it hands over when a researcher expresses interest. The published testimonials give no shared outcome definition or numerical count across clients.
6. North Star Scientific: outreach plus sales coverage
North Star Scientific offers email, LinkedIn, voice notes and phone outreach, with options for trade-show representation, senior sales execution and fractional commercial leadership. That wider scope could appeal to a supplier entering a new market without a full local sales team.
On its results page, the firm reports eight booked meetings in five months for an anonymized supplier of immunoassay kits and bioanalytical services. The page also shows activity volume, which helps frame the meeting count. Ask who would personally run your account, whether the brief covers meetings or later sales work, and how booked, held and qualified meetings appear in reports.
How to compare a lead generation proposal
Give each finalist the same narrow example. For a CDMO, that might be clinical-stage companies working in a modality you can manufacture, in a geography you serve. For a lab supplier, it might be groups using a particular assay technique, with an instrument replacement or procurement cycle ahead. Ask the firm to show the first ten accounts it would pursue and why each one belongs.
Then get five answers in writing:
- Who researches the accounts, who contacts the buyers and who runs the first conversation?
- Which channels will the team use on our campaign, and how much activity happens on each?
- What exactly counts as a qualified lead, a booked meeting, a held meeting and an accepted opportunity?
- Who owns the contact data, message history and follow-up when the engagement ends?
- Which past engagement has a buyer, offer and sales cycle close to ours?
A useful proposal names the people, channels and acceptance rule before promising a number of meetings. Two firms can hit the same meeting target while delivering very different work to your sales team.
Frequently asked questions
Is a lead generation firm the same as a lead database?
No. A database supplies company and contact records. The firms in this list also research fit, run outreach and qualify responses. Check which data sources they use and whether your team can retain the account and contact history.
Should we compare agencies by cost per meeting?
Only after you agree on what a meeting is. A scheduled call with the wrong title, no relevant project or no attendance can be cheap and still waste the sales team's time. Track booked meetings, held meetings, accepted opportunities and later contracts separately.
Which outreach channel works best for life science buyers?
The buyer and offer decide the mix. A scientist in a lab, a VP of CMC and a procurement lead have different schedules and reasons to speak with a supplier. Ask each firm which channels it would use for your named buyer roles and how it will change course when the first conversations show a poor fit.
If your team needs more direct buyer conversations
See Accel Bio's life science lead-generation service if a phone-first campaign fits your offer. Bring the products or capabilities you want to sell, the accounts you would most like to reach and your definition of a qualified meeting. Those details are enough to judge whether an outbound program makes sense.
