Immediate Joiner

We focus on multi-step flows that touch tools like CRM, ERP, ticketing, MES, and Git, and make them work together instead of in silos. We are especially strong in ops-heavy businesses such as pharma, manufacturing, B2B SaaS, and publishing.

We are:

• Part of Nvidia Inception and Google for Startups, with access to credits, tools, and mentors
• Bootstrapped and founder-led, focused on real revenue
• Early-stage, building the AI and growth stack from the ground up

This internship is a front-row seat to building a product and growth motion from zero to one.

About the Role

This is a 6-month, full-time internship with a strong intent to convert into a full-time role.

The role sits at the intersection of three pillars:

1. Performance marketing: Run measurable campaigns that generate qualified founder calls.
2. Growth experiments: Design, ship, and track small GTM experiments, weekly.
3. Storytelling: Turn what we learn from customers into sharp narratives across formats.

Your north star: Help Problock generate consistent, qualified pipeline through repeatable experiments.

What You’ll Work On 

You will own and contribute to:

Performance marketing & funnels

• Set up and run small-budget experiments across LinkedIn, email, and landing pages
• Define basic funnels: visit → lead → meeting booked → opportunity
• Track and improve metrics like CTR, reply rates, CPL, and call bookings
• Collaborate with the founder to refine offers, hooks, and targeting

Growth & revenue experiments

• Design and run 2–3 experiments every month (message tests, sequences, landing-page variants, lead magnets, etc.)
• Maintain a simple growth experiment log: hypothesis - setup - metrics - outcome - decision
• Build and maintain basic ICP and account lists for outreach
• Support structured outbound and follow-ups for founder-led sales
• 
  

Storytelling across formats

• Turn founder conversations, customer calls, and product ideas into:
• LinkedIn posts and threads
• Email sequences and one-pagers
• Short case-style narratives and website copy
• Repurpose one core idea into multiple formats each week
• Keep our story consistent: who we help, what problem we solve, why it matters now
• 
  

You’ll Thrive Here If You

• Have a founder’s mindset: bias for ownership, not instructions
• Are comfortable with uncertainty and incomplete information
• Enjoy switching between research, writing, numbers, and operations
• Are curious about AI, B2B SaaS, and customer experience
• Learn fast and document what you learn so others can use it
• Care more about building something real than about big titles

Basic Expectations

• Recent graduate or final-year student
• Strong written communication
• Comfortable with spreadsheets, Notion/Docs, and basic analytics
• Based in Bangalore

What You’ll Get

• 6-month internship with clear, upfront full-time conversion plan
• Stipend and, on conversion, competitive CTC with meaningful responsibility
• Direct access to the founder’s thinking, decisions, and trade-offs
• Experience building a product and GTM motion from the ground up
• Signal from Nvidia Inception and Google for Startups on your resume

Look further only if you are founder at heart and ready to bet six months on building something that can outlive this role.
