01
First Indian SaaS company
Celoxis was shipping subscription software out of India before the category had a name, and before the market it now serves existed.
About Celoxis
Twenty-five years on one problem: making execution visible.
Celoxis was built in 2001 by two engineers who kept watching capable teams lose control of capable projects. The platform has been in continuous development ever since, and the founders still write code.
- Founded 2001
- 500+ active customers
- SaaS or on-premise
Celoxis by the numbers
Our story
Built by the two engineers who needed it
Celoxis exists because its founders could not buy what they needed. Twenty-five years later, they still build it.
- Late 1990sSanta Clara, California
Chapter 01
The problem was on the next desk
Nikhil Daddikar and Ravindra Wankar were engineers at Fortune 500 companies and start-ups in the United States. Everywhere they looked, organizations were funding serious project work and still could not say where it stood - planning lived in one tool, collaboration in another, and the truth in neither. Nothing on the market was flexible or scalable enough to hold both.
- 2001Two years of code
Chapter 02
Celoxis ships
They went back to India to build the tool they wanted to use. Two years and millions of lines of code later Celoxis launched - a fully web-based platform in a market that still assumed project management meant desktop software, and the first Indian SaaS company.
- The decade afterBets that held
Chapter 03
Decisions that are still how it works
SaaS and on-premise from a single product. Free client portals. Configurable business workflows. Each shipped years before the category treated it as standard, and each is still in the platform today rather than deprecated behind a rewrite.
- Today25 years in
Chapter 04
Still built by its founders
500+ organizations across 10+ industries have planned and delivered over a million projects on Celoxis. Nikhil and Ravindra still write code and still read customer requests personally, which is why the roadmap answers to customers rather than to an acquirer.
We have come a long way from humble beginnings. We have weathered tough competition, global economic volatility and evolved with changing project management landscape.
In 2021 the team launched Tuskr, a cloud test management tool - built for the same reason as the first product.
Our mission
Run the work. Trust the numbers.
One system where teams run the work and leaders trust the numbers. Scheduling, people, financials and governance are natively unified, so execution data is accurate by design rather than assembled from spreadsheets after the fact.
Accurate by design
Execution data comes from how work actually runs, not from a report someone compiles later.
Decision-ready numbers
Rollups drill down to the constraint, so the answer arrives without a follow-up request.
Less admin, more execution
Nothing to reconcile. The portfolio view is a by-product of the work, not a second job.
We stay until outcomes are real
A dedicated account manager through rollout and beyond, rather than a ticket queue.
First movers
Four things Celoxis did before the category did
Being early is only worth claiming if the decision held up. These four did - each one is still how the platform works today.
02
SaaS and on-premise, from the start
The first platform in this category to offer both from the same product. Where your project data lives has always been your decision, not ours.
03
Pioneer of free client portals
Clients and external stakeholders got read access without a paid seat, so reporting to the customer stopped being a separate exercise.
04
First tool with business workflows
Intake, change requests and approvals were configurable inside the platform years before workflow became a standard PPM checkbox.
Why organizations choose us
What buyers tell us made the difference
Most accounts arrive after an evaluation against four or five other platforms. These are the reasons that decided it.
A single source of truth
Unlike fragmented project environments, Celoxis natively unifies people, time and financial data into one dependable system - so there is one version of the number, not one per department.
Portfolio-level decision support
Leadership gains operational visibility across the whole portfolio, with rollups that drill down to the constraint. Prioritization and investment calls get made in the meeting, not after it.
Resource and capacity precision
Forecast demand, allocate by skill and see over-allocation before it becomes a delay. Hidden bottlenecks surface while there is still time to move someone.
Financial governance
Real-time insight into budgets, actual costs, forecasts and portfolio ROI - held against the plan rather than reconstructed from invoices at quarter end.
Engineered for enterprise environments
On-premise deployment, configurability and the governance controls large organizations need to adopt a platform across business units rather than pilot it in one.
Infrastructure you can audit
Redundant connections and automated failover, encrypted off-site backups, role-based access and audit logs, aligned to SOC 2, ISO 27001 and GDPR requirements.
Industries
Built for work where delivery precision has a consequence
Celoxis is used by organizations where a slipped milestone shows up in a regulator's file, a client contract or a capital plan - not only in a status report.
Life Sciences & MedTech
Clinical trial portfolios, regulatory compliance tracking and multi-site programme delivery.
Engineering & Manufacturing
Complex project scheduling, capacity planning and cross-functional delivery governance.
Financial Services
Strategic programme oversight, financial governance and portfolio investment tracking.
Technology
Product delivery, resource visibility and PMO standardization across distributed teams.
Energy & Infrastructure
Large capital projects, contractor management and milestone-driven execution control.
Government & Education
Structured intake, governance frameworks and portfolio-level reporting for leadership.

Hover a region to trace it on the map
SaaS customers pick a U.S. or EU data center at sign-up. Organizations with stricter residency or control requirements run the same product on-premise, with the same open API either way.

Still the two people who wrote the first version
They met as engineers in the United States, built Celoxis together, and are still the ones deciding what it does next.
Co-Founder
Nikhil Daddikar
Born and raised in Mumbai. After five years building software for Fortune 500 companies and start-ups in the U.S., he and Ravindra concluded that no good collaborative tool for project management existed - so they returned to India and built one.
A life hacker at heart, with a weakness for poetry, art and anything beautiful that can be served in a dish.
Co-Founder
Ravindra Wankar
He spent his first years on large-scale programmes at corporations in India and the U.S., learning the nuances of project management from the inside, then turned entrepreneur to develop Celoxis with Nikhil.
