Best Outbound Agencies for Aerospace and Defense Suppliers

Aerospace and defense is not a normal outbound market. The Defense Industrial Base includes over 220,000 companies that process, store, or transmit CUI or FCI, according to the DoD CMMC Program final rule published in the Federal Register in 2024. In fiscal year 2024, DoD obligated $445 billion on defense contracts, more than all other government agencies combined, per the Congressional Research Service Defense Primer. Five companies alone received 30% of departmental contract obligations.

That concentration changes how outreach works. You are not emailing thousands of mid-market managers. You are reaching a small number of primes and their supplier quality, engineering, and program offices, where a single program win can carry a supplier for years. In Seqnced's view, generic SDR playbooks built for volume fit this market poorly.

Compliance also shapes the conversation. ITAR, administered under 22 CFR parts 120 to 130, controls defense articles and defense services. Sharing technical data with a foreign person inside the United States counts as a deemed export under 22 CFR 120.50. If your outreach team passes drawings or specs around, you need to know who can see them.

This section describes each firm in its own words, taken from their pages. Seqnced has not verified meeting counts, ratings, or results claimed by any agency listed here.

SalesHive describes its model as "SDR outsourcing, list building, and compliant outreach that books meetings with primes and GovCon buyers." Its page names DFARS, CUI, CMMC, ITAR, and FAR, and claims "129K+ qualified meetings booked" and "100% US-based SDRs." Salaria Sales says it helps clients "reach contractors, suppliers, and defense buyers with targeted Human-AI outbound campaigns."

Launch Leads positions itself as appointment setting: "We book qualified aerospace and defense conversations every week." Its page references AS9100 and ITAR and claims "152,000+ qualified appointments" and "16+ years." Echo-Factory describes itself in a search snippet as "the aerospace marketing agency, with more than 15+ years of commercial and defense aviation lead generation experience," leaning toward inbound leads.

Aprio, an accounting and advisory firm, offers "Tactical Business Development" across "the full acquisition lifecycle, from shaping opportunities and customer engagement to federal proposal management and post-award execution." GovIRG (Arrowhead Solutions) provides "Outsourced Business Development & Marketing for Government Contractors" covering opportunity tracking, bid/no-bid, and capture. Both are federal capture plays, not supplier-to-prime cold outreach.

Seqnced publishes this comparison, so weigh that. The case for placing it first is specific: Seqnced builds and operates outbound systems for sophisticated B2B companies with high annual contract values and real buying committees, which matches how primes actually buy from suppliers. Its founder, Remo Duzkale, previously led a family-owned steel company in Washington, D.C. that secured Department of Defense and aviation work. He has sat on the supplier side of this exact motion.

That background matters because the work is not just sending emails. Seqnced runs market mapping, account research, dedicated sending infrastructure, cold email, LinkedIn, warm calls after positive replies, reply qualification, pre-call nurture, and sales handoff. For a supplier selling machining, fabrication, or components into a program, the outreach has to speak to program context, qualification status, and capacity, not generic pain points.

Seqnced is an agency, not software. It does not sell lists or guarantee meetings. It builds the system and operates it, which suits suppliers who want a durable outbound function rather than a one-off campaign.

The market splits into two very different models. SDR shops like SalesHive, Salaria Sales, and Launch Leads run outbound campaigns aimed at booking meetings with primes and buyers. Capture firms like Aprio and GovIRG work the solicitation side: opportunity tracking, bid/no-bid decisions, shaping, and proposal management.

These are complementary, not interchangeable. If you have no pipeline of conversations with primes, capture support will not fill it. If you have conversations but lose at proposal stage, more cold email will not fix it. In Seqnced's review of public agency pages, few build supplier-to-prime outreach around AS9100 status, ITAR boundaries, and SBLO relationships specifically.

Ask any agency which of the two jobs it does. An honest answer saves you months.

Start with ITAR. Under 22 CFR 120.50(a)(2), releasing technical data to a foreign person in the United States is a deemed export. If your agency uses offshore SDRs or offshore researchers, ask whether any drawings, specs, or controlled context will touch those teams. If you only manufacture and never export, you still must register under 22 CFR 122.1(a), so your agency should understand that registration exists even at suppliers who think of themselves as purely domestic.

Ask about CMMC status. The CMMC Program rule took effect December 16, 2024, and the DFARS acquisition rule took effect November 10, 2025, per the Federal Register. On July 13, 2026, the Department of War announced the immediate suspension of CMMC Phase II requirements, though all Phase I self-assessment requirements remain in place, per the DoD CIO page. A reform task force report was due September 11, 2026 but had not been released publicly as of late September 2026, per Covington's Inside Government Contracts. Any agency speaking confidently about where CMMC lands should be able to cite its sources.

Finally, ask how they treat AS9100. The IAQG standard adds requirements over an ISO 9001 system and applies across the supply chain. In Seqnced's experience, certification status also shapes who at a prime will engage, often supplier quality or a commodity buyer.

Both, in sequence. Supplier portals and SBLOs are the formal channels primes use to source, and ignoring them means missing RFQs. But portals are crowded, and in Seqnced's experience a supplier who arrives with program context gets a better hearing. Direct outreach to engineering managers, commodity buyers, and program offices creates the relationship that makes a portal submission land.

The DoD numbers explain why patience pays. With five primes taking 30% of $445 billion in obligations, the account list is short and the stakes per account are high. That argues for researched, program-specific outreach over high-volume sequences.

Ask a prospective agency how it builds account research. If the answer is a firmographic list, the campaign will read like one.

Longer than a typical B2B campaign, and no agency should promise a date. Defense buying runs on program cycles, budget timing, and qualification requirements. A realistic expectation is that early meetings come from suppliers already on a prime's radar for expansion, while new program work takes quarters, not weeks.

Seqnced's aggregate experience across more than 10 million outbound emails, more than 100 campaigns, and more than 3,000 meetings generated informs its operating judgment, though past volume is not a promise of results for any single engagement.

When selecting an agency, ask three things: who on their team has sold into or for primes, how they handle controlled data, and what their qualification bar is for a meeting before it reaches your calendar. The answers separate operators from resellers.
