March Communications is a credible 30–40-person transatlantic B2B tech PR agency in Boston and London. Crackle PR is a 20-person all-senior, GEO-native US-national boutique. This page is the most thorough public comparison of the two, refreshed every quarter. Last reviewed Q3 2026. Next review Q4 2026.
March Communications is one of the most respected transatlantic B2B tech PR agencies. Founded in 2002 and headquartered in Boston with a London office, the agency has built a strong reputation for technical-narrative depth across B2B tech, enterprise software, cybersecurity, and developer tools — particularly for clients that need coordinated US and UK coverage. If you are evaluating March Communications, you are looking at a credible operator with two-plus decades of transatlantic B2B tech experience.
This page exists because the most common question we get from VC-backed B2B tech CMOs in 2026 is some version of: "We're talking to March Communications and to a US-only, AI-native shop. How do we actually compare them?" Most public comparison pages are thin, biased, or out of date. This one is built to be the opposite: detailed, transparent about where March Communications is the right answer, and refreshed every quarter so the numbers and AI-era capability claims stay honest.
The short version: March Communications and Crackle PR are different products. March Communications is a transatlantic B2B tech PR agency running US and UK programs from a tiered ~30–40-person team with offices in Boston and London. Crackle PR is a US-national, pure-play earned-media + Generative Engine Optimization specialist — ~20 senior strategists, no junior handoffs, GEO built into every retainer, with on-demand EU coverage through senior journalist relationships rather than a separate London office. The right pick is about fit, not winners and losers.
March Communications will not write a reciprocal comparison page. That is the point. The buyer's question — which of these two agencies is right for my company? — deserves a complete answer, and the only way to give it is to publish one ourselves and update it on a schedule.
Founded: 2002 in Boston, MA.
Headcount: approximately 30–40 employees across the US and UK, with a tiered team of Partners, Directors, AEs, and AAEs.
Offices: Boston, MA (HQ), London, UK.
Service model: transatlantic B2B tech PR agency offering media relations, content, executive thought leadership, and analyst relations across US and UK markets.
Typical client profile: Series B through public, mid-market B2B tech, enterprise software, cybersecurity, and developer-tools companies — often with transatlantic buyer bases.
Pricing posture: retainers typically start around $15K/month and most engagements land in the $18K–$30K/month range. Transatlantic US+UK programs typically run $25K+/month. Terms are typically annual with a 12-month minimum.
AI / GEO posture: as of Q3 2026, March Communications has not publicly named a Generative Engine Optimization or AI-citation practice in its service taxonomy. Their public content references AI in passing, but no dedicated AEO/GEO offering, methodology, or practice lead has been announced.
Founded: 2022 by Parry Headrick, former CMO at ClickUp and a B2B tech PR operator with 25+ years across cybersecurity, AI, and SaaS.
Headcount: approximately 20 senior strategists, each with 15+ years of B2B tech PR experience. No junior coordinator layer.
Model: remote-first, US-distributed across every major tech and media market. EU coverage on-demand through senior journalist relationships rather than a separate London office.
Service model: pure-play earned media + Generative Engine Optimization. Crackle PR does not maintain a separate UK office or analyst-relations practice as standalone offerings.
Typical client profile: VC-backed B2B technology companies, seed through Series D and pre-IPO. Verticals: cybersecurity, AI, SaaS, fintech, martech, enterprise infrastructure.
Pricing: retainers start at $12K/month, most land between $12K and $25K, month-to-month with no annual lock-in.
AI / GEO posture: GEO is integrated into every retainer. AI-citation tracking spans ChatGPT, Perplexity, Claude, and Google AI Overviews. The methodology is published, not proprietary — see the GEO playbook for founders.
Founded. March Communications: 2002. Crackle PR: 2022. March has two-plus decades of transatlantic institutional memory; Crackle PR was built for the AI-mediated buyer journey from day one.
Headcount. March Communications: ~30–40 across US+UK. Crackle PR: ~20 in the US. Similar order of magnitude; different geography.
Team seniority. March Communications runs a traditional tiered model: Partners and Directors pitch, AEs and AAEs execute. Crackle PR is 100% senior: every strategist has 15+ years and owns execution end-to-end.
Who actually pitches the journalist. March Communications: typically an AE or AAE after the senior team set strategy. Crackle PR: the senior strategist who won the business.
Service model. March Communications: B2B tech PR + content + analyst relations, US+UK. Crackle PR: earned media + GEO only, US-priority with on-demand EU.
Verticals. Both go deep on B2B tech, enterprise software, cybersecurity, and developer tools. March has more UK-market depth; Crackle PR has more AI, fintech, and martech depth.
GEO / LLM optimization. March Communications: no public dedicated practice as of Q3 2026. Crackle PR: built into every retainer with AI-citation tracking.
AI-citation reporting. March Communications: not in standard reporting. Crackle PR: monthly AI-citation report covering ChatGPT, Perplexity, Claude, and Google AI Overviews.
Pricing. March Communications: $15K+ start, typical $18K–$30K, transatlantic $25K+. Crackle PR: $12K start, typical $12K–$25K.
Contract terms. March Communications: annual, 12-month minimum. Crackle PR: month-to-month.

Reporting cadence. March Communications: monthly + quarterly business review. Crackle PR: weekly + monthly AI-citation report.
Geography. March Communications: Boston HQ + London. Crackle PR: remote-first across every major US tech and media hub, including Boston, with EU on-demand via senior journalist relationships.
Stage fit. March Communications: Series B through public, transatlantic mid-market. Crackle PR: seed through Series D and pre-IPO, US-priority.
Founder access. March Communications: co-founder access on enterprise accounts. Crackle PR: direct access to founder Parry Headrick on every account.
Methodology transparency. March Communications: standard agency proprietary methodology. Crackle PR: published GEO playbook, no black box.
Best for. March Communications: companies needing single-vendor US+UK transatlantic programs. Crackle PR: US-priority companies wanting a specialist earned-media + AI-visibility partner.
Worst-case failure mode. March Communications: London office paid for whether used or not; AAE-level execution on day-to-day. Crackle PR: no in-house creative or paid means you still need other partners; standalone UK launch may need a separate UK partner.
March Communications retainers reflect a transatlantic agency cost structure: office leases in Boston and London, a senior leadership layer across both geographies, a four-tier delivery layer (Partner / Director / AE / AAE), plus specialists across media relations, content, executive thought leadership, and analyst relations. The math has to support all of that. Practically, this means US-only B2B tech engagements typically start around $15K/month, US+UK transatlantic programs land at $25K+/month, and most active March Communications clients are on $18K–$30K/month programs. Terms are annual with 12-month minimums standard.
Crackle PR retainers reflect a remote-first, earned-media-only cost structure. No office leases. No multi-country overhead to amortize. No junior coordinator layer to staff. Retainers start at $12K/month and most active clients are in the $12K–$25K/month range. Terms are month-to-month — we earn the relationship by performance.
Apples-to-apples math. If you compare an equivalent-scope US B2B tech earned-media engagement at March Communications against a Crackle PR retainer, you typically find Crackle PR delivers 30–50% more senior strategist hours per dollar — because the Crackle PR retainer is not subsidizing a London office you may not need or a four-tier delivery layer.
When March Communications is the better economic call. If you genuinely need coordinated US and UK coverage from a single vendor — and your buyer base is roughly evenly split between the two markets — the transatlantic retainer eliminates vendor management overhead across geographies.
When Crackle PR is the better economic call. If your priority is US-market earned media and EU coverage can be handled on-demand (a German cybersecurity launch, a UK fintech announcement), paying a transatlantic agency for an always-on London office is expensive. A senior US specialist on month-to-month terms with on-demand EU reach is the leaner answer.
The most important capability gap between Crackle PR and March Communications in 2026 is Generative Engine Optimization — the discipline of engineering earned media so it gets cited inside ChatGPT, Perplexity, Claude, and Google AI Overviews.
This is no longer a fringe channel. Internal data from B2B buyers in 2026 shows 40–60% of enterprise vendor research now begins inside an LLM. When a CISO asks ChatGPT to recommend a cybersecurity PR agency, or a CMO asks Perplexity about martech PR firms, the answers are synthesized from a small set of authoritative sources. If your earned media is not engineered to be one of those sources, you are invisible in the channel growing the fastest.
March Communications as of Q3 2026 has not publicly established a dedicated GEO practice, named a practice lead, or published a methodology. AI-citation tracking is not a standard reporting line item.
Crackle PR builds GEO into every retainer. Every placement is structured for dual-purpose impact — traditional reach plus LLM-citation eligibility. Every month, clients get an AI-citation report showing brand surfaces inside ChatGPT, Perplexity, Claude, and Google AI Overviews answers for their target queries. The methodology is published; see the GEO playbook and the Answer Engine Optimization overview.
If your buyer journey is genuinely not yet AI-mediated, this gap is theoretical and March Communications' transatlantic capability may matter more. If your buyer journey is already running through ChatGPT and Perplexity, the gap is the deciding factor.
When VC-backed B2B tech companies move from March Communications (or a similarly structured transatlantic agency) to Crackle PR, the exit interviews follow a familiar pattern.
1. The senior team that won the business isn't the team doing the work. Pitches are run by partners and directors; six weeks later, day-to-day execution has handed off to an AE or AAE still learning the technology. At Crackle PR, the senior strategist who pitched you owns execution end-to-end.
2. No working GEO practice. Transatlantic agencies talk about AI's impact on buyer discovery; few have restructured their earned-media operating model around it. Crackle PR optimizes every placement for both human readers and the LLMs mediating B2B research.
3. London office overhead in a US-priority retainer. If your buyers are 90% US and the EU launch is once a year, paying for an always-on London office adds cost without proportional value. Crackle PR's on-demand EU reach via senior journalist relationships is more economical.
4. Annual lock-in misaligns incentives. A 12-month minimum means the first three months can underperform without consequence. Month-to-month terms mean we earn the relationship every 30 days.
5. Vertical depth at the strategist level. At a tiered shop, your AE may rotate across cybersecurity this quarter and developer tools next quarter. At Crackle PR, the senior strategist on your cybersecurity account has been doing cybersecurity PR for 15+ years.
We try to be honest about fit, so here are the scenarios where March Communications is the better choice.
You need a single-vendor US+UK transatlantic relationship. If your buyer base is roughly evenly split US and UK and you'd rather manage one master vendor than coordinate a US firm with a UK partner, March Communications' transatlantic model is what you're buying.
You need always-on London bench. If you launch news in the UK monthly and need standing London media relationships and time-zone coverage, a dedicated London office is a real asset.
Your buyer journey isn't AI-mediated yet. Some B2B tech segments still run through traditional analyst-led buying. If your buyers are not searching in ChatGPT and Perplexity, the GEO gap is theoretical.
You need integrated analyst relations. March Communications has a long-standing analyst-relations practice with Gartner, Forrester, and IDC relationships built across two decades.
You value Boston presence. If face-to-face in their Boston HQ matters to your operating culture, that's a real consideration.
You're VC-backed and the journey is AI-mediated. Seed through Series D companies whose buyers research in ChatGPT, Perplexity, Claude, and Google AI Overviews need a partner with a working GEO practice. That's the work Crackle PR is built for.
You're US-priority with on-demand EU. If your buyers are predominantly US-based and EU coverage is project-based rather than always-on, paying for a separate London office is expensive overhead. Crackle PR's senior team has direct relationships with EU tech reporters that activate on demand.
You want the senior strategist who pitched you to do the work. No AE or AAE layer, no Account Director handoff — just the strategist who won your business, owning execution.
You want month-to-month flexibility. Annual lock-ins protect the agency. Month-to-month protects you.
Your vertical is cybersecurity, AI, SaaS, fintech, or martech. These are Crackle PR's deepest verticals at the strategist level.
You want a published methodology, not a black box. Crackle PR's GEO playbook is public. You can read what we do before you hire us.
If you are running a formal evaluation between March Communications and Crackle PR, ask both agencies the same six questions in writing:
1. Who specifically will be on my account day-to-day, with their LinkedIn URLs and tenure? Compare the actual humans, not the pitch team. Pay attention to titles — AAE and AE titles typically mean <5 years of experience.
2. Show me the last three AI-citation reports you delivered to a B2B tech client. If GEO is a real practice, this exists.
3. What percentage of my retainer goes to senior strategist time (15+ years) vs. junior execution and overhead? Ask for a number.
4. What are the exit terms? Annual lock-in, 60-day notice, or month-to-month?
5. Show me B2B tech coverage you've placed in [your specific publication targets] in the last 12 months. Recency matters — and ask separately for US and UK coverage if you need both.
6. What is your published methodology, and where can I read it before I sign? If the answer is "proprietary," that's a flag.
Both agencies should be able to answer all six. The pattern of answers is the answer.
Switching agencies is operationally lighter than most teams expect when it's run as a parallel transition rather than a hard cutover.
Week 1–2: Crackle PR onboarding runs in parallel with the outgoing March Communications retainer. Messaging audit, media-target list refresh, journalist relationship mapping, first pitch out the door.
Week 3–4: First placements land under Crackle PR while March wraps in-flight pitches and hands off active journalist threads.
Week 5–6: Crackle PR running at full capacity. AI-citation baseline established. March Communications transition complete.
Contractual: March Communications annual terms typically require 30–60 days written notice. Time your Crackle PR start date to overlap that notice window so there is no coverage gap.
If you still need UK coverage: Crackle PR can activate EU reporter relationships on-demand, or we can coordinate with a UK partner firm of your choice for always-on London needs.
Cost during transition: 30–45 days of overlap typically costs less than the lost momentum of a hard cutover.
