Promi

What do they actually do

Promi is a Shopify app that personalizes discounts and prices for online stores. After installation, merchants set guardrails (budget, products, min/max discount), and Promi decides when and how much to discount per visitor in real time on-site or through email/SMS deep links. It renders personalized strikethrough pricing, supports onsite popups, and can trigger checkout-ready offers from campaigns (Shopify app listing; Promi site).

Merchants can run built-in A/B tests with control groups and track revenue/profit impact in dashboards. The app integrates with Klaviyo and works with Shopify Checkout and POS. Pricing includes a 21‑day trial and paid plans starting at $99/month with usage-based billing beyond plan quotas. Promi also markets automation that increases discounts on slow-moving SKUs and reduces discounts on items that sell well. Public reviews and case studies from merchants report improvements in conversion and revenue (Shopify app listing; Promi pricing; LinkedIn update; Shopify reviews; case studies).

Who are their target customer(s)

• Small-to-mid Shopify merchants with many similar SKUs who lean on discounts: Blanket discounts erode margins, while withholding discounts loses sales because they can’t tell who needs a nudge. They lack a way to target offers by visitor likelihood to convert (Promi — how it works; Shopify app listing).
• Merchants with slow-moving or overstocked inventory: Manually curating clearance lists and timing promotions is time-consuming and risks training customers to expect discounts across the catalog. They need automated, SKU-level discounting that doesn’t harm healthy sellers (LinkedIn update; Shopify reviews).
• Email/SMS marketing teams (often using Klaviyo): Campaigns use generic offers or force shoppers to find codes at checkout, hurting conversion. They want personalized, checkout-ready offers tied to each message (Shopify app listing — integrations; Promi — channels/deep links).
• Merchants without data/engineering resources: They struggle to run clean experiments and can’t tell if discounts raise profit or just cost. They need simple A/B tests and clear uplift reporting (Promi — A/B tests & dashboards).
• Growing and larger Shopify stores evaluating enterprise discounting: They need guardrails, budget controls, and support to scale personalized pricing without margin leakage as campaigns and traffic grow (Promi pricing — enterprise options).

How would they acquire their first 10, 50, and 100 customers

• First 10: Run high-touch pilots via YC and founder networks with white‑glove setup and a measured A/B test, then publish case studies and capture 5‑star reviews to build credibility (case studies; reviews; YC page).
• First 50: Optimize the Shopify App Store listing and trial-to-paid flow, and co-market with Klaviyo/Shopify agencies using webinars and how‑to guides that show setup and real uplift (app listing; Promi site).
• First 100: Make onboarding self-serve with templates and experiment presets for the 21‑day trial, add lightweight paid search/social around discount keywords, and layer in a small outbound/BDR motion for larger stores with enterprise onboarding as needed (pricing/trial).

What is the rough total addressable market

Top-down context:

Shopify powers millions of businesses in 175+ countries, providing a large installed base for apps that drive conversion and monetization (Shopify About us). Third‑party tracking estimates roughly 2.8 million live Shopify stores as of early 2026 (Store Leads).

Bottom-up calculation:

Store Leads’ breakdown suggests ~1.05M Shopify stores sell 50+ products (a closer fit for discount-driven catalogs) (Store Leads). If Promi targets 30% of that segment that actively runs discounts (~315k stores) at an average $150/month ($1,800/year), bottom‑up TAM is roughly $567M/year.

Assumptions:

• Focus on Shopify stores with 50+ products as the primary ICP proxy.
• Roughly 30% of those stores actively run discounts and are in-scope for personalized discount optimization.
• Average ACV ≈ $1,800/year ($150/month) given starting price points and usage-based tiers.

Who are some of their notable competitors

• Intelligems: Shopify-focused price and A/B testing platform that optimizes prices, shipping thresholds, and site changes; adjacent to Promi with strong traction among Shopify brands.
• Namogoo (Intent-Based Promotions): Delivers personalized offers and coupons based on buying intent; a direct competitor on individualized promotions and discounting.
• Prisync: Competitor price monitoring and dynamic pricing rules for ecommerce (including a Shopify app); overlaps on automated pricing but focuses on competitor-indexed pricing rather than per-user discounts.
• Talon.One: Enterprise promotion and loyalty engine with granular rules and segmentation; relevant for larger merchants building complex discount logic across channels.
• Voucherify: API-first coupons, referrals, and promotions platform used to orchestrate targeted offers; overlaps on promo personalization and governance for multi-channel campaigns.
