About

We install the Growth Operating System, so your team can operate independently.

Every engagement is structured around capability transfer. Pricing architecture, sales systems, and commercial infrastructure your team leads independently, with tools, playbooks, and operating cadences in place from day one.

Why We Exist

We've been inside 100+ businesses. The gap is never the strategy.

FintastIQ was founded by operators from McKinsey, BCG, and Bain who'd stayed long enough inside PE portfolio companies, high-growth startups, and enterprise organizations to watch what happened after the deck was presented.

The pattern was consistent: good recommendations, no operational infrastructure to run them. FintastIQ was built to close that gap. Pricing architecture, sales systems, marketing and GTM motions, and product strategy your team owns and runs independently, at the cost and speed a top-tier firm can't match.

How We're Different

Four operating principles. No exceptions.

Informed perspective from day one
A point of view grounded in data and shaped by 100+ engagement patterns. Tested and refined against your specific situation within 48 hours.
Build to Disappear
Every engagement ends with your team owning the commercial infrastructure we built together: tools, playbooks, and operating cadences that give your leadership team independence.
Senior operators on every engagement
Every engagement is led by experienced operators who've built the systems they're now installing. The team that scopes the work is the team that delivers it.
The full commercial system
Pricing, sales, marketing, and product don't operate independently. We work across all four because the highest-impact interventions almost always span multiple functions.

Your Price Reveals Your Conviction

06

Retention

Revenue Without Retention Is a Treadmill

07

Delegation

Set Direction. Scale Execution.

08

Capital Is a Tool. Not a Trophy.

09

Metrics

Stop Tracking. Start Fixing.

Systems

Build Systems Until You Can Disappear

From Build to Disappear by Emily Ellis. Published 2026.

What We Believe

Specific claims. Measurable standards.

Pricing is the highest-leverage P&L lever available to most companies. A 1% price improvement beats a 1% volume increase in EBITDA impact across nearly every business model.

Commercial excellence should outlast the engagement. Every system we build is designed to be sustained and evolved by your team, without ongoing external support.

The highest-impact work happens at the implementation layer. The best diagnostic creates no commercial value if the systems to capture it aren't built.

Specific, measurable claims over vague value propositions. We tell clients what we expect to find before we look, and we measure against it.

Who We Work With

Three client profiles. One operating model.

PE-Backed Companies
In value creation mode post-close. Commercial infrastructure needs to move from acquisition thesis to operational reality in a single quarter.
High-Growth Companies
Scaling commercial infrastructure ahead of the next funding round or preparing for a sale process. Product-market fit is proven. Commercial architecture hasn't kept pace.
Enterprise Organizations
Rebuilding pricing, commercial processes, or GTM after a market shift, acquisition, or leadership change. Large teams, complex systems, clear mandate for change.

Frequently Asked Questions

About FintastIQ.

What does FintastIQ actually build inside a PE portco?
FintastIQ is a commercial strategy firm that builds growth operating systems inside PE-backed, high-growth, and enterprise companies. We work across pricing architecture, sales effectiveness, marketing and GTM, and product strategy. We build systems, not reports, and every engagement is structured so your team owns and runs those systems independently.
How is FintastIQ different from McKinsey, BCG, or Bain on a commercial mandate?
Three things. We bring an informed perspective to every engagement, built from 100+ patterns rather than open-ended discovery. We build operational systems, not slide decks. And every engagement is structured for capability transfer: your team owns and runs the system after we're done.
Which company stage and ARR band does FintastIQ work with?
PE-backed companies in value creation mode, high-growth companies scaling commercial infrastructure, and enterprise organizations rebuilding pricing or commercial processes. We work best with clients whose senior leadership is committed to execution and whose operating team is ready to own the results.
What does Build to Disappear mean in a 90-day engagement?
Build to Disappear means every engagement is designed for your team's independence. We build operational infrastructure: processes, tools, playbooks, and dashboards your team owns and runs. Our measure of success is your team's ability to sustain and evolve the system after we leave.
What EBITDA impact has FintastIQ delivered across 100+ engagements?
Our team has contributed to over $8 billion in EBITDA impact across 100+ engagements. We come from McKinsey, BCG, and Bain backgrounds, and our model is built for operational implementation: building the systems, not writing the recommendations. 100% of our clients would recommend us. Referrals are our primary channel.
