If you searched for a list of the best Indian startup sectors in 2021, amidst industries like AI, climate tech, D2C, fintech, and gaming, ‘business compliance’ would not have made the cut. Founders avoid it. Investors don’t care about it. Most competent CAs in charge of this prefer to run their own practice quietly.
This is exactly why three Chartered Accountants and college friends decided to build a company around it. Five years later, RegisterKaro is one of India's best-known platforms for company registration, GST, trademarks, and ongoing compliance. The still-new startup surged with 50,000+ clients, 2,500+ new businesses incorporated every month, and 500+ professionals on the team. This month, the company launched its own app, which is a self-service platform giving clients a live dashboard, an encrypted document vault, and direct messaging with their assigned experts.
Here's the inside look at how they got here and four lessons for any founder building businesses in an unfashionable category.
Meet the Masterminds of RegisterKaro
RegisterKaro was started in May 2021 by Joel Lester D'Souza, Srihari R Dhondalay, and Sidharth Ravichandran: three Chartered Accountants who'd been classmates years earlier.
Joel had done time at Grant Thornton and is also a CFA charterholder, managing compliance and tech-led operations. Srihari leads the company's tax and labour-law practice & hosts RegisterKaro's live client-education sessions. Sidharth runs operations and client delivery. Between them, the trio brought finance, audit, tax, and compliance backgrounds.
The 3 young CAs stood out from other first-time entrepreneurs chasing a trend. They expertly identified the core problem that other first-time founders consistently get tripped up on and decided to build a business solving it.
Their business model is devised around helping entrepreneurs avoid making mistakes like choosing the wrong business structure, missing ROC deadlines, paying ₹100 per day in late fees with no upper cap, or not even knowing what GSTR-3B was until a notice arrived.
The Growth Chart: From RegisterKaro Company Registration to 300+ Services in 5 Years
RegisterKaro's first office was a two-bedroom apartment in Koramangala, Bengaluru, in September 2021. In October 2022, they moved to a formal office in Indiranagar. In April 2023, they relocated their headquarters to Gurugram to be closer to the north and west India's MSME clusters. By May 2024, they'd opened in international grounds.
Today, the numbers show their outstanding upscaling:
- 50,000+ clients served across startups, SMEs, and established businesses
- 2,500+ new companies incorporated every month
- 500+ professionals on the team with CAs, CSs, lawyers, and tax practitioners
- 4.7-star Google rating across 8,000+ client reviews
The growth has tracked closely with India's own surge in formal business creation. Each month, over 20,000 companies register with the MCA, and the number of Udyam-registered MSMEs has exceeded 7.8 crore, which is about ten times more since 2021-22.
Revenue Model: Services + Subscriptions, B2C + B2B
RegisterKaro runs a hybrid revenue model:
- One-time services: Company registration, Trademark filing, GST registration, FSSAI, Udyam, IEC, and similar one-time services. This is the entry point for most clients.
- Recurring subscriptions: Annual ROC compliance, Ongoing tax filing, Bookkeeping, Payroll, Virtual Office, and Audit support. This is where the lifetime value sits and why every incorporation client gets into a long-term compliance relationship.
It's the SaaS playbook adapted for legal and accounting:
Low-friction entry product → high-trust subscription → expansion into adjacent services as the client's business grows.
Latest Move: Turning a Services Firm Into a Product Company
The RegisterKaro App, launched in April 2025, is the company's biggest technology investment so far. The founders deem it to be a deliberate attempt to convert a services business into a product-led one. The app rolls up everything into one mobile interface:
- A real-time tracking dashboard showing the status of every active service,
- A secure document vault,
- Direct messaging with assigned professionals, and
- A complete record of invoices and payments.
The new portal cut turnaround times for routine filings in half and significantly reduced the number of status-check requests. This change allowed the team's CAs and CSs to focus more on valuable advisory work.
Beyond paying clients, the app opens up a compliance calendar and library of plain-language guides covering information related to every business structure in India. The same educational instinct that the founders have applied to their content strategy is visible on organic channels.
Looking ahead, the company has said the app will form the base for an AI-assisted compliance dashboard, designed to flag upcoming obligations, recommend filings, and help prepare routine documents automatically.
4 Lessons for Founders Building in an "Overlooked" Category
1. Compliance is unglamorous, recurring, and high-trust, and that is the underrated moat. RegisterKaro didn't try to disrupt a hot category. Instead, they picked a deeply painful one and went deep.
2. All three founders are practicing CAs. They didn't outsource the domain to a hired team. They were the team for the first year. In services businesses, this is the difference between scaling and stalling.
3. Free content is a long-term moat.RegisterKaro's blog publishes detailed explainers on the Companies Act, GST, ROC filings, and more, reviewed by the founders themselves. Years of consistent, useful content built brand recall well before the app launched.
4. Productize the back-office. RegisterKaro could have stayed a pure services firm forever. Instead, they invested in technology that turned status updates, document storage, and deadline alerts into a self-serve product, freeing their human experts for the work that genuinely needs them.
What's Next on the Agenda
The next phase, as per the founders, is about depth more than reach: multi-entity management for clients running multiple businesses, AI-assisted compliance recommendations, a referral programme built into the app, and continued expansion of cross-border services for Indian founders setting up subsidiaries abroad and foreign founders setting up in India.
We are building RegisterKaro for the long term. India incorporates millions of new companies every year, and each one deserves a compliance partner that is transparent, efficient, and digitally equipped. – Joel D’Souza
It's a pragmatic vision, not a flashy one. But then, the whole RegisterKaro story has been a quiet refutation of the idea that you need a sexy category to build a meaningful business. Sometimes, the most boring problems are the ones worth solving.
