Case Study: CodeLab EdTech – B2B Corporate Training via LinkedIn
Client: CodeLab Corporate Training (Bengaluru, India) | Industry: Education & EdTech | Service: LinkedIn Marketing | Duration: 5 Months
1. Executive Summary
Key Wins at a Glance:
- 180 B2B corporate leads generated every month (from zero LinkedIn presence)
- 22 enterprise contracts signed within 5 months
- Rs. 5.4 Crore annual recurring B2B revenue unlocked
- Cost per lead (CPL) reduced by 96% – from Rs. 45,000 (referral cost) to just Rs. 1,800
- Cold outreach response rate jumped from 2% to 38% using LinkedIn Sales Navigator + thought leadership
Within 5 months, we transformed CodeLab from a referral-dependent training provider into a data-driven B2B lead generation machine on LinkedIn.
2. The Challenge
CodeLab Corporate Training, based in Bengaluru, offered high-quality upskilling programs in AI, cloud computing, and full-stack development. However, they faced a critical growth bottleneck:
- Cold email response rate below 2% – L&D decision makers at enterprises ignored generic emails.
- No LinkedIn strategy – Their company page had only 340 followers, and the CEO had never posted thought leadership content.
- High dependence on referrals – 85% of revenue came from word-of-mouth, which was unpredictable and slow.
- Target audience was hard to reach – HR heads, L&D managers, and CTOs at mid-to-large Indian companies were not engaging with traditional outbound.
- Sales cycle was long – Average 90 days from first touch to contract, with no structured follow-up system.
CodeLab needed a scalable, repeatable way to reach decision makers, build trust, and close deals faster. They came to AK Network Solutions for a LinkedIn-first strategy.
3. Our Strategy
We designed a three-pillar LinkedIn marketing strategy tailored for B2B corporate training buyers:
Pillar 1: Precision Targeting with LinkedIn Sales Navigator
- Built 12 high-intent lead lists targeting: HR Heads, L&D Managers, CTOs, and VP Engineering at companies with 500+ employees in Bangalore, Mumbai, Delhi NCR, Pune, and Hyderabad.
- Used advanced filters: job function (L&D, HR, Training), seniority (Manager to C-Level), company size (200-10,000 employees), and industry (IT, BFSI, Manufacturing).
- Excluded competitors and irrelevant profiles to maintain high relevance.
Pillar 2: Thought Leadership Content Engine
- Positioned CodeLab’s CEO as a “Corporate Training Futurist” with weekly LinkedIn posts on: “How AI is Reshaping L&D Budgets”, “Upskilling ROI: Why 83% of Indian Enterprises Are Investing in Micro-Credentials”.
- Created 4 LinkedIn Carousels per month: “5 Signs Your Team Needs a Custom Upskilling Program” and “Cost of Not Training: Rs. 12 Lakh per Developer per Year”.
- Published 2 long-form articles on LinkedIn Pulse targeting L&D trends in Indian enterprises.
Pillar 3: LinkedIn Lead Gen Forms & Paid Campaigns
- Launched 6 LinkedIn Lead Gen Form campaigns offering: “Free L&D Audit Report”, “Corporate Training ROI Calculator”, and “Sample Module Access: AI for Managers”.
- Used matched audiences to retarget website visitors and email lists.
- Set daily budget of Rs. 8,000 with A/B testing on headlines, CTAs, and form fields.
Tools Used: LinkedIn Sales Navigator (Team Plan), LinkedIn Campaign Manager, Canva (for carousels), HubSpot (CRM integration), and Google Analytics for UTM tracking.
4. Implementation (Step-by-Step)
We executed the strategy in 4 phases over 5 months:
Month 1: Foundation & Setup
- Optimized CodeLab’s LinkedIn company page: added keywords, client logos, and a clear “Corporate Training Partner” tagline.
- Set up Sales Navigator: built 12 lead lists with 2,500+ decision makers.
- Crafted 5 personalized outreach templates (connection request + follow-up sequence).
- Launched first 2 Lead Gen Form campaigns with “Free L&D Audit” offer.
Month 2: Content & Engagement
- Posted 3 thought leadership pieces per week from CEO’s personal account.
- Sent 50 personalized connection requests daily (using Sales Navigator’s InMail + custom notes).
- Ran first LinkedIn Carousel ad: “5 Signs Your Team Needs Upskilling” – reached 48,000 impressions.
- Started weekly LinkedIn Live sessions with L&D experts (average 120 attendees per session).
Month 3: Scaling & Optimization
- Scaled outreach to 80 connection requests per day with follow-up InMails.
- Launched 2 more Lead Gen campaigns: “Corporate Training ROI Calculator” and “Sample Module Access”.
- Implemented A/B testing on ad creatives – found that “Case Study” headlines outperformed “Free Offer” by 34%.
- Integrated HubSpot to track lead source and automate follow-up emails.
Month 4-5: Conversion & Contracting
- Focused on high-intent leads: scheduled 45 demo calls with decision makers.
- Used LinkedIn Sales Navigator’s “Spotlight” feature to identify leads who engaged with content.
- Closed 22 enterprise contracts (average deal size: Rs. 24.5 Lakh annually).
- Refined targeting based on data: reduced CPL by 22% from Month 2 to Month 5.

Detailed Performance Data:

- Conversion Rate: 12.2% of leads converted to demo calls (industry average: 3-5%). 22 contracts closed from 180 demos – a 12.2% close rate.
- Revenue Impact: Rs. 5.4 Crore in annual contract value (ACV) from new enterprise clients. Average deal size: Rs. 24.5 Lakh per year.
- Cost Efficiency: CPL of Rs. 1,800 vs. Rs. 45,000 per referral lead – a 96% reduction in customer acquisition cost.
- Engagement Metrics: CEO’s LinkedIn posts averaged 2,500+ impressions and 85+ engagements per post. Company page followers grew from 340 to 4,200.
- Response Rate: Cold outreach response rate improved from 2% (email) to 38% (Sales Navigator + personalized notes).
Context: CodeLab had previously spent Rs. 3.2 Lakh per month on cold email tools and data lists with almost zero ROI. Our LinkedIn strategy delivered a 25:1 ROI within 5 months (Rs. 5.4 Cr revenue vs. Rs. 2.16 Lakh total ad spend).
6. Key Takeaways
What Worked Best:
- CEO-led thought leadership built trust fast. Decision makers responded to authentic, data-rich posts about L&D challenges. The CEO’s personal brand became CodeLab’s biggest asset.
- Sales Navigator + personalized outreach beat email. Custom connection notes referencing specific company challenges (e.g., “I saw your team is hiring for AI roles – here’s how we upskilled 200 engineers at [Company]”) achieved 38% response rate.
- Lead Gen Forms with low-friction offers worked. “Free L&D Audit” and “ROI Calculator” had 14% form completion rates – 3x higher than industry average for B2B.
- Consistency was key. Posting 3x/week and sending 80 connection requests daily created compounding results by Month 3.
- Data-driven targeting eliminated waste. We continuously refined lists based on engagement, dropping low-intent segments (e.g., junior HR roles) and focusing on senior L&D leaders.
Lessons Learned:
- Don’t underestimate the power of LinkedIn Carousels – they generated 40% of all content engagement.
- A/B test ad copy relentlessly. We found that including “Case Study” in headlines increased CTR by 34%.
- Integrate CRM early – HubSpot automation saved 15 hours/week in manual follow-ups.
