Presto Phoenix raised $10 million from Remus Capital-affiliated and existing investors to scale its enterprise Voice AI drive-thru platform amid expanding QSR deployments and partnerships.
Presto Phoenix, Inc. (Presto), the San Mateo, California-based leader in enterprise grade Voice AI for quick service restaurant (QSR) drive-thrus, raised $10 million from Remus Capital-affiliated investors and other existing investors. This follows an earlier $10 million infusion in January 2026 (led by Metropolitan Partners Group, with Remus Capital, Link Ventures, and strategic angels including ElevenLabs CEO Mati Staniszewski). The September round builds on operational traction rather than introducing new external lead investors.
What is Presto Phoenix?
Presto Phoenix emerged from the January 2025 Article 9 asset sale of the prior public company Presto Automation (Nasdaq: PRST). A consortium led by Remus Capital (with Link Ventures and Metropolitan Partners Group) acquired the Presto Voice platform, technology, and team, injecting $18 million in fresh capital at the time and rebranding the entity as a private company focused exclusively on Voice AI for drive-thrus.
The predecessor had gone public via SPAC in 2022, faced significant challenges (including capital constraints and prior regulatory issues around AI claims), and shifted under new ownership to emphasize production scale reliability over pilots. Co-founder Krishna Gupta (also founder of Remus Capital) serves as CEO. The company positions itself as a Y Combinator alum with deep restaurant industry roots dating to 2008, specializing in handling complex enterprise menus (customizations, modifiers, regional items, promotions).
Presto Voice automates drive-thru ordering to raise order accuracy and throughput, reduce labor dependency, enable consistent upselling, and standardize guest experiences. Reported metrics include high non intervention rates (up to ~95% in some references), strong upsell offer rates, and incremental revenue lifts (e.g., up to 6% monthly in company materials). It has powered millions of real world interactions.
Details of the Latest Funding
- Amount and investors: $10 million from Remus Capital-affiliated investors and other existing backers. No new external lead is highlighted; this is supportive capital from the post acquisition ownership group.
- Use of proceeds: Accelerate Presto’s leadership in drive-thru Voice AI by expanding deployments, advancing technology/product capabilities, and increasing customer impact. Emphasis is on product investment, operations scaling, and helping QSRs digitalize/standardize (especially their highest volume channel).
- Timing and momentum: Announced amid expansion of existing customer deployments, new brand launches, product enhancements, a Toast Partner Ecosystem integration (announced ~1 week earlier on September 21, 2026), and partnerships with AI specialists including ElevenLabs (voice) and Bluejay (part of the proprietary platform).
CEO Krishna Gupta stated: “Over the past several months, we’ve continued to prove that Voice AI can deliver meaningful results at scale across some of the most demanding drive-thru environments and menus. We are investing heavily in product and operations as we help more of the industry adapt to the inevitable agentic future. Every QSR brand is realizing they must increase digitalization and standardization across their business, and Presto is the natural partner to help them do that for their largest channel – it all starts with Voice.”
John Tincoff of Remus Capital noted clear tailwinds from the labor environment, the need to standardize best practices, and the importance of data for competing in an agentic AI landscape.
By early 2026 Presto was already the AI partner to about a dozen enterprise brands, with deployments across hundreds of drive-thrus (more customers and geographies than peers, per company claims) and a goal of reaching thousands of locations. Named or referenced customers/partnerships include Taco John’s, Hardee’s/Carl’s Jr. (CKE), Fazoli’s, Wienerschnitzel (Galardi Group), and Dairy Queen locations. The Toast integration specifically targets mid market and multi location operators modernizing POS systems, broadening reach beyond pure enterprise custom deployments.

Caplight data (as of around the September period) lists an estimated valuation near $595 million and cumulative funding figures in the hundreds of millions (reflecting the prior public company history plus post acquisition capital), with the company ranked in the top 5% for momentum among tracked firms. Exact post September valuation is not publicly detailed.
Drive-thrus often represent 70%+ of QSR revenue. The U.S. market includes roughly 140,000 drive-thru locations and substantial order volume. Labor pressures, consistency demands, and the shift toward agentic/data driven operations are accelerating adoption of Voice AI. Competitors and alternatives include SoundHound AI, Hi Auto, ConverseNow, Valyant AI (acquired), in-house or Big Tech co-developed systems (e.g., Wendy’s with Google, Taco Bell/Yum! deployments), and others. Presto differentiates on enterprise scale complexity handling, production reliability, and vertical focus rather than pure demos.
The QSR AI/ordering automation space is growing rapidly, with projections for broader AI in restaurant markets reaching multi-billion levels over the coming years. Success hinges on real world accuracy in noisy environments, POS/menu integration depth, measurable ROI (accuracy, speed, upsells, labor savings), and the ability to scale beyond pilots.
The September $10M is growth capital that reinforces the post restructuring trajectory: private ownership by AI specialist and prior lender investors, focus on proven deployments, product maturation (voice quality, menu management, data capture), ecosystem partnerships (Toast + AI voice providers), and aggressive expansion. It signals continued investor confidence after the January round and 2025 recapitalization.
Key strengths include operational proof points at scale, alignment with structural QSR pain points, and a platform approach aiming at broader vertical AI/automation. Risks typical to the category remain, accuracy in edge cases, franchisee adoption variability, competition from both specialists and large platforms, and the need to convert deployments into durable, high margin revenue. Presto’s stated ambition is clear market leadership in drive-thru Voice AI as the industry moves from experimentation to standardization.
