Key Outcomes From This Journey
Where These Systems Were Built
The through-line across every organization below is the same: the outcome came from redesigning how the work happens, not from adding people to the existing design. That is why the operating expenditure reductions and the service improvements happened at the same time rather than trading against each other.
Augnito

- → Reduced operational expenditure by 50% through automation and process redesign.
- → Standardized clinical onboarding and enterprise implementation systems.
- → Introduced CS playbooks, frameworks and SOPs across Support, Customer Success, Implementation and Support.
- → Led implementation of platforms including NiceX, Hubspot, Zoho, Twilio, Freshsuccess and Internal CRM.
- → Built alignment frameworks across Product, CS, and Sales.
Keka HR

T-Hub
India's Largest Startup Incubator- → Operations and customer success work inside India's largest startup incubator.
- → Exposure to early-stage company building and startup operations.
- → Worked across a portfolio of young companies rather than a single product, which surfaces the failures that repeat everywhere.
- → Founders with no playbook, no process and no time is a useful constraint to design against.
Iris Business Solutions

[24]7.ai
Entry into Large-Scale Customer Operations- → Entered a much larger ecosystem of customer operations, scale and technology-driven execution.
- → First exposure to customer operations run as an industrialized system rather than as a team.
- → Learned how volume changes every assumption: staffing, routing, quality and what a process has to survive.
- → The bridge from ground-level retail into enterprise customer execution.
Advisory & Consulting
Retail and HRTech Operators- → Consulted for retail and HRTech companies on customer operations, support structure and onboarding design.
- → Brought operating patterns to teams that needed the system but not the headcount to build it in-house.
- → Worked the same problems from outside the org chart: ownership gaps, undefined escalation, and onboarding that stalls before value.
- → Translated enterprise-scale playbooks into something a small team could actually run.
Early Retail Operations
MedPlus, Religare, Shoppers Stop, Reliance Retail, Lifestyle- → Worked retail floors from a young age across pharmacy, department store and lifestyle retail, at MedPlus, Religare, Shoppers Stop, Reliance Retail and Lifestyle.
- → Served customers face to face, long before any of it was called Customer Experience.
- → Learned how operations actually behave under footfall, stock pressure and a queue that does not care about process.
- → Everything built later, the systems, the playbooks, the escalation paths, is an attempt to scale what a good floor manager does instinctively.
Four Patterns That Held Across Every Engagement
Operating expenditure fell by roughly half at both Augnito and across the Keka build, while response times and onboarding speed improved. That combination is only possible when the underlying process changes. Cutting cost without changing the design degrades service; adding people without changing the design raises cost without fixing consistency.
At Freecharge, automating payment status checks only worked because the knowledge base and 1,000-plus documented payment FAQs came first. Automating an undefined process industrializes the confusion. The sequence is always define, then standardize, then automate.
Across these organizations the recurring diagnosis was not that teams were too small. It was that no single role owned the customer outcome end to end, so work fell between functions. Naming an owner costs nothing and is consistently the fastest visible improvement.
Interviewing over 5,000 candidates at Keka and hiring 300-plus, including 10 leaders, only scaled because enablement and role definition existed first. Hiring into an undefined structure reproduces the inconsistency at greater expense.
Case Studies: Frequently Asked Questions
What companies has Chethan Kumar S built Customer Success systems for? +
Chethan Kumar S has built customer operations at Augnito (Healthcare AI, scaling Customer Success across India, the Middle East, UK, USA, and Australia), Keka HR (HRTech SaaS, 8,000+ clients), Freecharge (Fintech, 100,000+ support tickets per month), T-Hub (India's largest startup incubator), and Iris Business Solutions, which he founded. Earlier operational roles span MedPlus, Reliance Retail, and Shoppers Stop.
How was a 50% OPEX reduction achieved without cutting headcount? +
Through automation and process redesign rather than staff reduction. At Augnito this meant standardizing clinical onboarding and enterprise implementation, introducing playbooks and SOPs across Support, Customer Success, and Implementation, and consolidating the platform stack. Cost fell because the work itself changed, which is also why service levels improved at the same time instead of degrading.
How did first response time drop from 8 hours to under 2 hours? +
At Freecharge, handling over 100,000 tickets monthly, the improvement came from restructuring triage, building knowledge infrastructure including a knowledge base with over 1,000 documented payment FAQs, implementing Freshdesk and Wolken support desks, and automating payment status checks so a large class of tickets resolved without an agent. Capacity was redesigned, not simply expanded.
What does building a Customer Success operating system actually involve? +
It involves defining the lifecycle stages and what happens at each, assigning explicit account ownership, establishing health signals and escalation paths, standardizing onboarding to a defined value milestone, selecting and integrating the tooling that supports those processes, and creating a governance rhythm that reviews the system on a fixed cadence. Without the last part, the rest decays.
Are these case studies applicable outside SaaS? +
The specific tactics vary by industry, but the underlying patterns transfer. The work spans Healthcare AI, HRTech SaaS, Fintech, startup incubation, pharmacy retail, and large-format retail. In every case the recurring constraint was ownership and process design rather than effort or headcount, which is a structural issue common to any customer-facing operation.
Facing a Similar Problem?
If you are scaling customer operations, trying to reduce cost without degrading service, or rebuilding a function that has outgrown its original design, that is the work.
