Collaborate. Solve Problems. Build Community.
Welcome to Business
Casual
Business Casual is a San Diego-based consulting and advisory practice helping people build better businesses — and better lives — by solving real operational problems with heart, clarity, and creativity.
We work alongside founders, nonprofit leaders, and small business owners to bring order to the chaos, clarity to the strategy, and energy to the next phase of growth. Whether that means mapping a three-year plan, untangling a vendor issue, or just sitting down to ask the right questions — we're in it with you.
Because real change doesn’t always need a full-time hire.
Sometimes it just needs the right person in your corner.
About Business Casual
Who we are. Why we started. What we believe.
Business Casual was founded by Sanjay Sinniah, a former Fortune 500 leader turned fractional operator and strategic partner. With two decades of experience leading teams across continents and industries — and a knack for making complex things make sense — Sanjay started Business Casual to work with people who value collaboration, clarity, and meaningful progress.
We Believe In:
Showing up curious and unafraid to ask hard questions
We don’t arrive with a playbook—we arrive with curiosity. Every organization is different, and surface-level solutions rarely solve the real issues. So we listen carefully, ask questions that might make you pause, and challenge assumptions—not to be difficult, but to get to the truth faster. Growth starts with clarity, and clarity comes from asking better questions.

“Sometimes the real problem isn’t the one you thought you had. We help uncover what’s underneath.”
Solving real problems, not symptoms
We’re not here to slap band-aids on broken processes or duct-tape your to-do list. We help you dig deeper and tackle root issues—whether that’s a lack of alignment, an outdated system, or an unclear strategy. When you solve the right problem, progress gets easier and more sustainable. That’s our sweet spot.

“Quick fixes wear off. We help you solve the right problem, for good.”
Putting people and community at the center of every decision
Businesses don’t grow in isolation. They grow because of people—teams, clients, families, and communities. That’s why we don’t just focus on metrics and milestones. We focus on the humans behind the work. Whether we’re reducing costs, navigating transitions, or scaling strategy, we aim for impact that lifts everyone.

“When you center people, better business naturally follows.”
What We Do
Strategy, structure, and support for people building things that matter.
From day-one startups to 20-year-old nonprofits, we help people navigate change and drive progress.
Our work spans:
Business Diagnostics & Strategic Planning
Fractional COO + Ops Management
Cost Reduction & Vendor Strategy
Implementation & Accountability Support
Advisory for Boards, Founders, and Executive Teams
Clients range from founders figuring it out for the first time to seasoned operators who just need a trusted voice in the room.
Whether you need one strong push or long-term collaboration — we build the support model around you.
Who we work with
Startups. Nonprofits.
Small & Growing Businesses.
Business Casual is built for people in the messy middle — the kind of people who are too big to wing it, too lean to waste time, and too mission-driven to settle for mediocre.
We specialize in helping:
Startups establish operational foundations and scale smart
Nonprofits navigate leadership transitions, funding pressure, and strategic alignment
Small Businesses organize operations, plan for succession, or just get unstuck
We’re not trying to impress the Fortune 100. We’re here for the real ones — the bagel shops, the community health orgs, the founders bootstrapping with purpose.
