Learn moreWhy Cornorstone
A different kind of
consulting firm.
Most planning consultancies optimize for headcount. We optimize for outcomes. Cornorstone is small on purpose — built to take on a handful of Anaplan engagements at a time and run them with the same architect from kickoff to go-live.
No bait-and-switch on senior staff. No model handed to a junior after week two. No Slack channels you stop hearing back on. Just a clear scope, a working model, and someone on the other end who actually cares whether it lands.
More about usFounder-Led
Every engagement is run by Atishey directly. No staffing pyramid, no offshore handoff.
Anaplan-Deep
We picked one platform and went deep. FP&A, Supply Chain, Sales Performance, Workforce.
Boutique by Design
Small client list on purpose. You get attention, not a ticket queue.
Straight talk
Cornorstone is a young firm built on a senior practitioner's playbook. If you need a logo wall, we're not the right fit. If you need someone who'll own the model and answer the phone, talk to us.
How We Work
The Cornorstone Way
Five phases. One architect from start to finish. No surprise invoices, no off-shored builds, no junior consultant left holding your model.
Discover
Two weeks with your finance, ops, or sales team. We map the real process — not the deck version.
Design
Module architecture, list strategy, and sizing. Reviewed with you before a single line is built.
Build
Hands on the keyboard. Atishey writes the model. You see progress weekly, not at the end.
Validate
Reconcile against the source of truth. Edge cases first, happy path second.
Hand Over
Train your owners, document the model, and stay on call through the first close cycle.

Use Cases
Proven Solutions
Deep expertise across 6 Anaplan use cases — each delivered at enterprise scale with measurable outcomes.
The Problem
Enterprise finance teams drown in disconnected spreadsheets, manual data consolidation, and month-long budgeting cycles. Forecast accuracy suffers, and leadership lacks real-time visibility into financial performance.
Our Approach
We build connected Anaplan FP&A models that automate data flows, enable rolling forecasts, and provide real-time P&L, balance sheet, and cash flow visibility. Our models integrate with ERP, CRM, and HR systems to create a single financial truth.
The Outcome
Clients achieve 60% faster planning cycles, 30% improvement in forecast accuracy, and real-time executive dashboards that drive better capital allocation decisions.
