Runstack builds AI agent systems that run your repetitive ops — lead scoring, follow-ups, support replies, retention — so your team stops copy-pasting between WhatsApp, your tools, and sheets.
We automate high-volume operations by connecting your front-end channels to your core back-office systems.
Capture inquiries from Instagram, WhatsApp, email, and web forms instantly. Our AI agents parse each incoming query, verify details, score purchase intent, and route hot leads to the right team members immediately.
AI agents listen to inbound channels, instantly consolidating inquiries into a single unified queue.
The system cross-references the sender's metadata against Shopify and CRM records to identify existing customers or repeat inquiries.
An LLM-driven classifier grades lead value and intent confidence, separating high-buying inquiries from spam.
High-value prospects trigger a Slack notification containing customer details and a context-aware drafted reply.
Never let a warm prospect go cold. We build structured WhatsApp and email sequences that re-engage abandoned checkouts, custom invoices, and stalled conversations. The AI agent handles objections, answers common product FAQs, and guides customers to buy.
Shopify indicates an abandoned checkout, or a CRM stage changes to "Follow-up required".
The system triggers a WhatsApp or email referencing the specific items and offering help.
If the user replies, the agent answers questions about shipping times, sizes, or stock availability in real-time.
The agent helps the buyer choose and routes them straight to a pre-filled cart with discount codes applied.
Cut support workloads without sacrificing response speed. AI agents handle order tracking, returns processing, and common brand inquiries automatically. For complex or sensitive issues, the system performs a clean handoff to your team.
Inbound support tickets are parsed to identify order references, customer email, and query type.
The agent queries Shopify and AfterShip to pull tracking numbers, delivery dates, and package locations.
The system sends status updates, triggers shipping delay notifications, or initiates return labels instantly.
If a customer is upset or asks something complex, the ticket escalates to a human with the draft response ready.
Turn one-time buyers into loyal brand advocates. Automatically trigger satisfaction surveys, NPS capture, photo review requests, and personalized re-order offers based on the purchase frequency of your products.
Carrier confirms delivery, triggering a countdown calibrated to the brand's usage cycle.
A friendly chat check-in is sent via WhatsApp to capture feedback before asking for reviews.
Highly satisfied buyers are directed to upload photos/reviews directly to Shopify integrations like Okendo/Loox.
If a product is consumable or seasonal, the agent triggers a replenishment offer at the exact re-order window.
These reflect our current focus and real work in progress — not a list of every industry served.
Order support, retention flows, and lead follow-up automation for online brands. This is our current core focus.
Client intake, document processing, and scheduling automation. Based on a working demo built for a law firm pitch.
Lead scoring and follow-up automation for property inquiries, appointment booking, and post-viewing feedback capture.

You're still checking DMs, replying to order queries, and updating sheets yourself.
2–5 people handling a volume of repeat, low-judgment tasks that don't need a human every time.
Order volume is growing faster than your team can keep up with manually.
I'm Pramit. I started Runstack because I watched too many founders and small ops teams get buried in low-judgment, repetitive tasks. They were spending hours copying data between Shopify and sheets, sending manual WhatsApp follow-ups, or copy-pasting tracking links.
My background is in software systems and API integrations. I believe AI works best when it runs behind the scenes as a quiet operations assistant. It shouldn't just draft marketing copy — it should coordinate your tools and handle your day-to-day operations reliably.
We don't sell generic chatbots or make promises about replacing your entire staff. We sit down, map your specific workflow triggers, write plain code, connect your real-world tools, and deliver a system you own.
If you are still checking Instagram DMs at midnight or updating tracking numbers by hand, we should automate it.
We find the exact trigger, decision points, tools involved, and where a human still needs to approve something.
The agent system is connected to your real tools and tested against your actual past cases before going live.
You get a working system, a run log you can audit, and a clear path for what to automate next.
Fixed packages mapped to the complexity and integration requirements of your operations.
Final pricing depends on tools, complexity, and integrations. Confirmed after a free audit.
Answers to common questions about scoping and delivery of custom AI automation workflows.
We price based on the complexity of the workflow logic, the specific APIs/tools involved, and the volume of trigger events. A simple WhatsApp notification sequence is priced differently than a full system that syncs Shopify data, scores lead intent, and updates CRM status across multiple platforms.
Our Growth and Custom packages include a 14-day support and monitoring period after implementation goes live. During this window, we monitor agent run logs, fix API connection errors, and fine-tune LLM prompts based on real-world usage to ensure the system is stable.
A single Starter workflow is typically developed, tested, and handed over within 7 days. More complex connected systems (Growth package) are delivered and launched in 10 to 14 days. Custom enterprise automation timelines are scoped out individually.
We do not charge recurring monthly subscription fees for our development work. You only pay for your own API usage (e.g., OpenAI or WhatsApp API credits) and standard tool subscriptions. We build on infrastructure that minimizes your operating overhead.
