Case Study: How “Rohan” Boosted His Sales Using AI Tools

Background:
Rohan is a 28-year-old sales executive for a mid-size software company in Pune. He handles B2B sales for HR software and was struggling with three problems:

  • Spending hours manually finding prospects
  • Poor cold email response rates
  • Losing track of follow-ups

Step 1: Prospecting with Apollo.io
Rohan started using Apollo.io’s free plan to download 50 verified HR Manager contacts every month. This alone saved him ~10 hours per week compared to LinkedIn scraping.

Step 2: Organising Pipeline in HubSpot CRM
He moved all his leads to HubSpot’s free CRM. Now calls, emails, and meetings log automatically, and HubSpot AI sends him reminders to follow up.

Step 3: Personalising Emails with ChatGPT
Instead of writing each email from scratch, Rohan pasted the prospect’s LinkedIn headline into ChatGPT. It generated a personalised intro and subject line in seconds.

Step 4: Optimising Cold Emails with Lavender.ai
Before sending, Rohan pasted his email into Lavender.ai. The tool told him to shorten paragraphs and add a clearer call-to-action. His open and reply rates doubled from 10% to 22%.

Step 5: Prioritising Hot Leads with Freshsales’ Freddy AI
When his lead list grew large, Freddy AI inside Freshsales highlighted the top 20 hot prospects. Rohan focused only on them, closing 3 deals in one week.

Result:

  • Saved ~15 hours/week in admin work
  • Doubled cold email reply rate
  • Closed 30% more deals in the quarter

Key Lesson: By combining free AI tools, even a solo salesperson can act like a full team.
