Everstone integrates Wingify, AB Sweet’s $100M+ digital optimization platform

Private equity firm Everstone Capital is bringing together Indians Wingify – a company that helps businesses test different versions of their websites to improve sales and customer engagement – is French AB Sweet building a $100 million technology optimization company with over $100 million annual revenue, just one year after acquisition controlling stake in Winify for $200 million.

The combined business will serve more than 4,000 customers worldwide and generate more than $100 million in annual revenue, with approximately 90% coming from the US and Europe and groups in North America, Latin America, Europe, and Asia-Pacific, the company said Tuesday. Wingify co-founder Sparsh Gupta will lead the combined entity as CEO, while Everstone will remain the majority shareholder.

The partnership comes as digital tools, including A/B testing and customization, are converging, as businesses look to deploy AI across marketing, sales and growth teams without tying together multiple vendors. The combined company will invest more in AI-driven services over time, while maintaining the customer experience in the short term and gradually expanding the depth of its platform, Gupta said in an interview.

Everstone is raising additional capital as part of the deal, Mr. Gupta told TechCrunch, explaining that the goal is to “clean up” AB Tasty’s table and bring the two businesses together under one platform. Financial terms were not disclosed, although the Guptas indicated that the deal included a buyout of existing management, which would allow them to own shares in the new entity.

Gupta pitched the deal as a natural alliance between the longtime rivals. “Both businesses have been operating as friendly competition,” he said, adding that the merger reflects a growing need from businesses to create integrated, digital experience platforms.

The joint team will be led by a core team from both organizations. Along with Gupta as CEO, Wingify co-founder Ankit Jain will become Chief Product and Technology Officer, while AB Tasty’s co-founders will take on key roles: Rémi Aubert will be Chief Customer and Strategy Officer and Alix de Sagazan will be Chief Revenue Officer, the companies said.

Both Wingify and AB Tasty are profitable, Gupta said, and the merger is focused on building an integrated platform rather than cutting costs. “No layoffs are planned as part of this merger,” he added, describing the rationale as “making a profit at this time.”

The combined company will have about 800 employees in 11 offices around the world, with about 350 employees based outside India, Gupta said, adding that the combined organization will be based in New Delhi.

Co-founded in 2010 by Paras Chopra and Gupta, Wingify remained bootstrapped for more than a decadewith VWO being its flagship product, helping businesses increase online conversion rates through A/B testing and customer optimization. Everstone acquired a large stake in the startup in January 2025, which also marked Chopra’s big exit, as TechCrunch previously reported. This partnership set the stage for the Everstone platform that has now led to the integration of AB Tasty.

Wingify counts more than 3,000 brands as clients, including Forbes, Walt Disney, Amway, Hilton Vacations, TAP Portugal, and Cigna, in all sectors such as e-commerce, SaaS, travel and media.

Founded in 2014 and headquartered in Paris, AB Tasty offers a program to test and customize used by more than 1,000 brands, including L’Oréal and Samsonite.

The combined company will compete in the same category as players such as Optimizely and Adobe, giving Singapore-headquartered Everstone and Wingify a bigger foothold in Europe while expanding the platform’s product segment by testing, sending features, and customizations guided by AI, subject to closing conditions and approvals.

The partnership adds to the growing integration in marketing and software products, as business and consumer intelligence companies look to assemble a platform, ready for AI to serve global customers. A recent PitchBook report shows SaaS M&A businesses have taken action 270 deals in Q3 worth $65 billionand revenue of 26.2% quarter over quarter, with private funds accounting for 66.7% of sales. In general, PwC last year known Integration of (PDF) as a key strategy for business development, and EY highlighted. private equity led by tech M&A in 2024 as consumers pursue platform growth and AI capabilities.

Gupta told TechCrunch that Everstone will retain most of the control over the combined business and will have more control over the boards after the transaction. The board will have five to six seats, including representatives from Everstone and Gupta, along with three to four independent directors, he added.

Everstone said it will return the combined company with additional support, including an advisory group of industry experts and employees. “Together, VWO and AB Tasty will have some of the best offerings in the group,” said Sandeep Singh, managing director at Everstone Capital.
