Operational excellence for interior design firms

Great design deserves great operations.

Helping design studios run as wonderfully as the spaces they create.

The challenge

Where creativity meets operations

Most design studios win on talent and taste, yet the back office rarely gets the same attention. The work between concept and install is where margin can slip, teams feel stretched, and growth slows.

Evolving scope, unbilled hours

Design revisions and client changes that don't always make it onto an invoice.

Procurement complexity

Coordinating orders, replacements, and delivery windows across dozens of vendors.

Disconnected tools

Design files, spreadsheets, and email threads that each hold part of the picture.

Every decision comes to you

The principal is personally involved in every decision, approval, and detail.

The engagement

Two phases, one lean path

Phase One

Discovery & Diagnostic

Fixed fee · scoped to your firm

A structured look at your studio through six lenses comprising your people, your clients, your numbers, and your ways of working. Ends with a full findings and recommendations presentation, including some quick wins. Priced up front as a fixed fee, with no surprises.

Phase Two · Optional

Implementation

Scoped from the Phase One roadmap

Lean Street delivers the prioritized improvements with you: process redesign, automation and AI deployment, and capability transfer so the gains stick. Priced by the scope you approve, with no obligation to proceed.

Phase One · Discovery & Diagnostic

Your studio through six lenses

Voice of the Employee

Confidential interviews with designers, project managers, and studio staff: the day-to-day experience from the inside.

Voice of the Customer

Client interviews and journey feedback, from first consultation through final installation.

Performance Metrics Review

Utilization, timeline adherence, and project KPIs: what the numbers reveal.

Financial Health Review

Profitability by project type, pricing model, procurement markups, and cost structure. A check for revenue leakage, plus an accounting process deep dive.

Process & Workflow Mapping

Concept-to-install mapping that shows where hand-offs and workflows can run more smoothly. Identify process bottlenecks and low-value tasks.

Technology & Systems Assessment

Design, project, and procurement tools, and where automation and AI will pay back. Hardware, cloud, file storage, Wi-Fi, bandwidth, and cybersecurity constraints that add risk and slow productivity.

Phase One · Process & deliverables

A clear path to a clear plan

1

Listen

Interviews, data & financials

2

Examine

Metrics, finance, process & tech

3

Recommendations & roadmap

4

Present

Full presentation to leadership

Findings & Recommendations

A clear, evidence-based readout of what's working, where margin can improve, and exactly what to change, grounded in all six lenses.

Quick Wins

Improvements you can capture immediately: pricing fixes, process shortcuts, and simple automations, many within days of the presentation.

Prioritized Roadmap

A value-ranked improvement plan that sequences the bigger moves and defines the scope for an optional Phase Two.

Phase Two · Optional

From recommendations
to results

Phase One identifies the priorities and why they matter. In Phase Two, Lean Street works alongside your team to deliver the improvements, so the roadmap becomes lasting results.

Scope, timeline, and investment are defined together at the end of Phase One. You commit only to what the roadmap justifies.

Process redesign

Streamlined concept-to-install workflows with clear ownership and hand-offs.

Automation & AI deployment

Practical tools for proposals, procurement tracking, client updates, and reporting.

Studio scoreboard

A simple set of metrics so you can see margin, utilization, and progress at a glance.

Capability transfer

Your team trained to run, own, and keep improving the new ways of working.

We are pleased to provide this reference for David Clarke and his work with Tomas Pearce.

David was initially engaged as a management consultant to conduct a comprehensive business evaluation of Tomas Pearce and to suggest improvement opportunities. His assessment was thorough and insightful, and we, the principal partners agreed with all of his recommendations. On the strength of that work, we offered David an interim CEO role in order to implement those changes and oversee the resulting transformation period.

In that role, David consistently demonstrated the kind of initiative, technical judgment, and leadership that made a measurable difference to our business, both in the numbers and in the way the organization runs day to day.

A few highlights from David’s time with us:

  • Financial impact: David renegotiated key contracts, adding an estimated $500,000 to our bottom-line profit; a result that reflected both his commercial acumen and his ability to build a strong case for change with stakeholders.
  • Technology infrastructure: He led a complete upgrade of our server and computer hardware, eliminating IT-related productivity bottlenecks that had been holding the team back.
  • Financial operations: David improved our bookkeeping and accounting processes and recruited a new accountant with specialized expertise in interior design, strengthening the financial function to better match the needs of our business.
  • People leadership: He managed a team of 15 direct reports, improving HR processes, driving a genuine culture shift, and automating manual HR workflows that had previously consumed significant staff time.
  • Commercial strategy: David challenged long-standing assumptions about contract scope and what qualified as additional billable work or service requests. This shift in approach and attitude led to a significant increase in associated revenue.
  • IT and cybersecurity: He sourced and onboarded a new IT support provider, materially improving our cybersecurity posture, IT processes, and overall service quality.
  • Systems migration: David oversaw the full migration and associated staff training for our project management and procurement system after the legacy platform was discontinued, ensuring a smooth transition with minimal disruption.

Overall, David provided significant tangible and intangible improvements and solutions to Tomas Pearce. He combines strategic thinking with hands-on execution, and he is equally comfortable managing people, renegotiating commercial terms, or overseeing a technical migration.
