When Meridian Growth first started as a B2B lead generation agency in 2023, they were managing LinkedIn outreach for 12 clients using a patchwork of tools, spreadsheets, and manual processes. By mid-2025, they were running campaigns across 200 LinkedIn accounts, generating over 2,000 qualified meetings per month for their clients, with zero account bans in eight consecutive months. This is how they did it.
The Challenge: Growing Pains at Scale
Meridian Growth's founding team -- CEO Rachel Torres and CTO David Kim -- built the agency on a simple premise: B2B companies need meetings with decision-makers, and LinkedIn is the most effective channel to create those meetings at scale. Their early success proved the thesis. But as they grew from 12 to 50 client accounts, the operational complexity became overwhelming.
The Tool Fragmentation Problem
By early 2024, Meridian was using three different LinkedIn automation tools simultaneously. Each tool had different interfaces, different safety settings, different reporting formats, and different pricing structures. Campaign managers spent nearly 40% of their time on administrative overhead rather than strategy and optimization.
"We had a campaign manager who was spending two hours every morning just logging into different platforms, checking for alerts, and compiling reports into a single dashboard," Torres recalled. "That is two hours of a skilled employee's day wasted on busywork."
The Proxy Cost Problem
Running 50 LinkedIn accounts through cloud-based automation required 50 dedicated residential proxies. At an average cost of $15-25 per proxy per month, proxy costs alone were running $750-$1,250 monthly -- a significant line item that ate directly into margins. Worse, the quality of these proxies was inconsistent. Some providers would rotate IPs unexpectedly, triggering LinkedIn warnings. Others would share IPs across too many users, leading to elevated restriction rates.
Kim estimated that proxy-related issues (account warnings, temporary restrictions, proxy provider troubleshooting) consumed 15-20 hours per month of his team's time.
The Account Safety Problem
Between January and June 2024, Meridian experienced 7 client account restrictions -- a 14% restriction rate across their managed accounts. Each restriction meant difficult client conversations, manual account recovery processes (which could take 1-3 weeks), and in two cases, permanent loss of the account.
"When a client's LinkedIn account gets restricted, they don't blame LinkedIn. They blame us. And they should -- we're the ones managing the automation. Every restriction was a trust event that put the client relationship at risk." -- Rachel Torres, CEO
Finding Infonet: The Evaluation Process
In July 2024, Kim began evaluating alternatives. His requirements were specific:
- Single platform: One tool to manage all accounts, not three
- Team management: Role-based access so campaign managers could see only their assigned accounts
- IP solution: Something better than the proxy provider roulette they were playing
- Safety track record: Demonstrably lower restriction rates
- AI personalization: To improve response rates and differentiate from competitors
- API access: For custom reporting and CRM integration
- Cost efficiency: Total cost per account needed to decrease, not increase
After evaluating six platforms, Meridian chose Infonet. The deciding factors were the InfoProxy hardware solution (which addressed the proxy problem at the root level), the team management capabilities, and the AI personalization engine.
The Migration: 50 Accounts in 3 Weeks
Meridian migrated their 50 active accounts to Infonet over three weeks in August 2024. Kim's team developed a systematic migration process:
- Week 1: Migrated 10 accounts as a pilot batch. Tested safety settings, campaign templates, and reporting workflows.
- Week 2: Migrated 20 more accounts. Refined the process based on Week 1 learnings. Began deploying InfoProxy devices to clients.
- Week 3: Migrated the final 20 accounts. All accounts operational on Infonet by month-end.
The InfoProxy deployment was the most logistically complex part. Meridian shipped InfoProxy devices to each client's office with a one-page setup guide. "We were worried about the hardware component," Torres admitted. "But out of 50 clients, only 2 needed a support call during setup. Everyone else had their device connected in under 5 minutes."
Scaling to 200 Accounts
With the infrastructure problems solved, Meridian focused on growth. Between September 2024 and January 2026, they scaled from 50 to 200 managed accounts. Here is how Infonet's platform supported that growth.
Team Structure
Meridian organized their team into pods, each managed through Infonet's team management system:
- 4 Campaign Managers -- each overseeing 50 accounts, responsible for campaign strategy, messaging, and performance
- 2 Data Analysts -- managing prospect lists, enrichment data, and performance analytics across all accounts
- 1 AI Specialist -- optimizing AI personalization settings, refining value propositions, and managing A/B tests
- 1 Account Safety Lead -- monitoring account health, managing InfoProxy devices, and maintaining safety protocols
Each team member had role-based access within Infonet. Campaign managers could only see their assigned accounts. The safety lead had read-only access across all accounts. Analysts had access to reporting data but could not modify campaigns.
InfoProxy at Scale
Managing 200 InfoProxy devices across 200 client locations sounds like a logistics nightmare. In practice, it was surprisingly manageable. Meridian ordered InfoProxy Pro devices in batches of 25, pre-configured them with pairing codes, and shipped them to clients with a branded quick-start card.
Remote monitoring through Infonet's dashboard gave the safety lead real-time visibility into every device's status. If a device went offline (usually due to a power outage or router reboot), the system automatically paused automation and sent an alert. The safety lead would then contact the client to confirm the device was back online before resuming.
Total monthly proxy cost for 200 accounts: included. The InfoProxy devices were a one-time purchase, and the cloud proxy is bundled with Infonet subscriptions. Compare that to their previous proxy spend of $15-25 per account per month, and the savings alone justified the migration.
AI Personalization as a Competitive Advantage
As a lead generation agency, Meridian competed directly with dozens of other firms offering LinkedIn outreach services. The AI personalization engine became their primary differentiator.
"When we pitch prospective clients, we show them side-by-side examples: a message from a template-based competitor versus an AI-personalized message from our Infonet campaigns," Torres explained. "The difference is obvious and it closes deals for us."
Across their 200 accounts, Meridian's AI-personalized campaigns consistently outperformed industry averages:
- Connection acceptance rate: 48% (vs. 28% industry average)
- Reply rate: 19% (vs. 7% industry average)
- Positive reply rate: 11% (vs. 3% industry average)
- Meetings booked per 1,000 prospects: 42 (vs. 15 industry average)
The Results: 8 Months, Zero Bans
The most significant metric was the one that mattered most: account safety. Between June 2025 and January 2026 -- an 8-month period during which Meridian was operating at full scale with 200 accounts -- they experienced zero account bans and only 3 temporary warnings (all resolved within 24 hours by briefly pausing activity).
Compare that to their pre-Infonet period: 7 restrictions in 6 months across only 50 accounts. The improvement was not incremental. It was transformational.
Financial Impact
The numbers told a compelling story:
- Proxy cost savings: $3,000-$5,000/month eliminated entirely
- Tool consolidation savings: Replacing three platforms with one reduced software costs by $2,800/month
- Operational efficiency: Campaign managers reclaimed 8+ hours per week previously spent on multi-platform administration
- Total cost reduction: 60% decrease in per-account operating costs
- Revenue impact: Higher response rates and zero account losses enabled 3x pipeline growth for clients
Client Retention
Before migrating to Infonet, Meridian's client retention rate was 72% annually -- respectable but not exceptional. In the 12 months after migration, retention improved to 91%. Torres attributed this directly to two factors: better campaign performance (driven by AI personalization) and the elimination of account safety incidents.
"No client has left us because of an account issue since we switched to Infonet," she said. "That was the number one reason clients churned before."
Lessons Learned
Torres and Kim shared several lessons from their scaling journey that apply to any team managing LinkedIn outreach at scale:
1. Infrastructure before volume. "We tried to scale on a shaky foundation and it almost broke us. Fix your tooling, fix your IP security, and fix your team processes before you add more accounts."
2. Hardware proxies pay for themselves. "The ROI calculation on InfoProxy was embarrassingly obvious. We were spending more on proxy providers in 3 months than the devices cost upfront. And the devices work better."
3. AI personalization compounds. "The AI gets better the more data it has. Our campaigns today perform meaningfully better than our campaigns 6 months ago, without us changing our strategy. The engine just learned what works for each client's ICP."
4. Hire a safety specialist early. "Having one person whose entire job is monitoring account health was a game-changer. They caught potential issues before they became problems."
5. Standardize your processes. "Every client gets the same onboarding flow, the same InfoProxy setup, the same campaign template to start. Consistency at scale is what makes this manageable."
What's Next for Meridian Growth
As of early 2026, Meridian is on track to reach 300 managed accounts by year-end. They are exploring Infonet's API to build custom dashboards for their clients and are testing multi-channel sequences that combine LinkedIn with email outreach.
"Two years ago, we were a scrappy agency barely keeping 50 accounts alive," Torres reflected. "Today we are an infrastructure company that happens to do lead generation. The platform made that possible."
