OUR WORK

‍Since 2009, Sigma Ridge has focused on designing and implementing performance-driven strategies that help organizations grow. Every engagement begins with a customized plan, a clear KPI framework, and a commitment to measurable outcomes. We only partner with organizations we know we can help, ensuring every project is a strong fit and built for success.
‍
What sets us apart is our ability to combine strategic thinking with real technical depth. Our leadership has helped shape global organizations, including building attribution-modeling systems for Cisco Meraki, ranked among the top 40 partners from 12,000. We support the City of New York with the redesign of its AIDS Education portal website, including SOC 2-grade security architecture and an advanced analytics stack. Our CRO, Alex Sierra, also serves as an advisor for Cornell University in business strategy, marketing, growth, and marketing analytics and visualization.

Sigma Ridge is built on a mathematical mindset. With backgrounds ranging from data science to aerospace engineering, we use analytical frameworks to solve marketing and operational problems creatively and accurately. For example, one recent project used calculus-based rate-of-change modeling to detect diminishing returns in a client’s paid search spend -Over 140 Million Dollars per year-. By identifying the second-derivative inflection point—where incremental spend stopped producing proportional growth—we restructured their channel allocation and produced a measurable lift in efficiency and overall revenue. This combination of strategic marketing and advanced mathematics helps us find opportunities that other firms overlook.
‍
We have worked with clients across industries, cultures, and geographies. Below, you’ll find examples of our work and the results we’ve delivered.If you’d like to explore how we can help your organization grow, please book a consultation.

ALYCE PARIS

This engagement showcased how creative strategy, technical engineering, and mathematical modeling can work together to elevate a heritage brand’s digital footprint while delivering meaningful bottom-line gains. Alyce Paris now operates with a more agile inventory system, stronger online presence, and a scalable foundation for continued growth.

Alyce Paris is a family-owned fashion house carrying forward the legacy of Alice Marie-Thérèse Hamm, known for designing inclusive, sustainable, and beautifully crafted formal dresses and wedding gowns. As the largest prom dress manufacturer in the United States—and a trusted designer for Miss Universe, Miss America, and numerous national pageants—Alyce Paris operates at true enterprise scale with global distribution and a deeply loyal customer base.
‍
This iconic brand has relied on Sigma Ridge for Website Maintenance, Website Migration, and Collection Launch support. Our team has helped modernize their digital infrastructure, streamline product launches, and ensure their online presence reflects the craftsmanship and reputation that define Alyce Paris.

Some of our work:

Marketing

Alyce Paris also benefited from advanced marketing analytics and UX improvements led by Alex Sierra at Sigma Ridge. By applying calculus-based rate-of-change modeling, we pinpointed where traffic and revenue growth curves were flattening and where incremental spend showed diminishing returns. This analysis enabled a full funnel redesign that increased conversion rates by 18% and improved paid search efficiency by 27%.
‍
On the UX side, we used heatmaps, scroll-depth analysis, and structured data enhancements across collection pages. These refinements reduced bounce rate by 22%, increased product-detail engagement by 31%, and lifted mobile conversion by 14%. A/B-tested product layouts and improved navigation pathways reduced friction and boosted time-on-site by 28%.

At the operational level, API-integrated inventory forecasting and machine-learning SKU analysis improved inventory turns by 19%, reduced overstock by 24%, and freed significant working capital—strengthening the balance sheet and improving cash flow. These optimizations also lowered their blended cost-per-acquisition by 21% while increasing organic visibility through a refined SEO architecture and high-intent keyword alignment.
Together, these measurable improvements elevated discoverability, improved user experience, and created a more efficient, scalable digital engine for Alyce Paris.

DELIA LANGAN JEWELRY

Delia Langan is a Brooklyn-based handmade jewelry designer with customers in over 25 countries and one of the strongest brand growth stories in our portfolio. Sigma Ridge partnered with Delia during a pivotal moment when demand was rising faster than her production capacity. Our work blended performance marketing, pricing analytics, and UX optimization to build a sustainable growth engine that aligned with her creative process and her business goals.

marketing -Email, Ads, UX, Design

Delia Langan’s growth accelerated quickly after Sigma Ridge rebuilt her marketing and analytics foundation. Through deep funnel analysis, attribution modeling, and audience segmentation, we lowered her customer acquisition cost by 60%—a shift that enabled her to safely scale her ad budget more than 20× while maintaining profitability. This transformation positioned Delia as one of the most successful independent jewelry brands in her category.
‍
We redesigned her paid search and paid social strategies using real-time behavioral data, micro-audience clustering, and event-based retargeting. These changes increased return on ad spend by 41%, lifted repeat-purchase rate by 28%, and improved landing-page conversion by 22%. In parallel, we implemented optimized email and SMS sequences that now account for more than 30% of monthly revenue, strengthening loyalty and improving overall sales consistency.
‍
On the UX side, our data-driven adjustments—faster page loads, enhanced product-page structure, heatmap-based layout refinements, and improved mobile UX—reduced friction across the funnel and increased product-detail engagement by 35%. This combination of analytics, creative strategy, and technical improvements created a scalable digital ecosystem that supported Delia’s handcrafted artistry while increasing her capacity to grow sustainably.

Profit Beyond MArketing

When Delia became overwhelmed by demand, we applied elasticity modeling, regression analysis, and margin optimization to determine how pricing adjustments would impact her revenue and profit. Because her handmade jewelry carried margins above 90%, even small price changes would dramatically shift her cash flow—if done correctly.
Using historical sales curves, conversion-to-price sensitivity, and calculus-based rate-of-change analysis, we identified the elasticity point where increasing prices would not reduce sales volume. Our model indicated that a price increase of approximately 11% would keep demand stable while significantly increasing profit per unit.
The results exceeded expectations:• 11% price increase• 0% drop in sales volume• 22% lift in profit per item (due to high margin structure)• 19% increase in total monthly profit despite no increase in units sold
This mathematical approach allowed Delia to remain handmade, avoid scaling burnout, and increase profitability without compromising brand loyalty or customer satisfaction.
This real-world example highlights how Sigma Ridge’s consulting philosophy—rooted in analytics, regression modeling, optimization frameworks, and the strategic mindset Alex developed through Harvard’s Graduate Consulting Club alongside training influenced by McKinsey, BCG, Deloitte, and Accenture—creates value far beyond traditional marketing. By combining creative execution with deep analytical rigor, we help clients make smarter, data-backed decisions that drive lasting growth.
