Most ecommerce tech stacks grow organically: a tool added here, a workaround there, an integration built under pressure. The result is a fragile, expensive ecosystem where changing one thing breaks three others. We evaluate your current stack and your future requirements, then design a coherent architecture where every component earns its place and talks cleanly to its neighbors. We’re vendor-agnostic and ruthlessly practical. The goal is a stack that scales with you — not one that holds you back. **This is for you if:** - Your current stack is a patchwork of tools that don’t integrate well and require too much manual intervention. - You’re about to make a significant platform investment and want to make sure the surrounding ecosystem supports it. - Your tech costs are growing faster than your revenue and you suspect there’s redundancy you’re not seeing. **What you’ll get from this:** - A map of your current stack with an honest assessment of what stays, what goes, and what’s missing. - A target architecture designed for your scale, your team’s capabilities, and your integration requirements. - Vendor-agnostic recommendations with clear rationale. - A transition plan that sequences changes to minimize disruption and maximize early wins.

Is that too small an engagement?Not at all: the map of your current stack, with an honest read on what stays, what goes, and what’s missing, stands on its own as a deliverable. You also get vendor-agnostic recommendations with clear rationale, so the opinion is something you can act on rather than a slide. Whether you act on it with us or without us is genuinely your call. Our internal team knows the stack better than anyone external could. Why bring in outside eyes?Your team knows the individual tools better than we ever will; that’s exactly why an outside, vendor-agnostic view helps. Nobody on the inside has to defend a tool they championed two years ago, so the assessment of what stays, what goes, and what’s missing comes out honest. We map the stack with your team, not around them. How do you make sure the recommendations aren't just steering us toward tools you have a relationship with?We’re vendor-agnostic by design: no reseller margins, no preferred partner list, no commissions shaping the shortlist. Every recommendation comes with written rationale tied to your integration requirements, your team’s capabilities, and your scale, so you can audit the reasoning yourself. If a cheaper or simpler tool fits, that’s the one that goes in the document. We're about to make a major platform investment. Should this come before or after that decision?Before, ideally: making sure the surrounding ecosystem supports a major platform investment is one of the exact scenarios this work is built for. The target architecture shows whether the platform you’re considering talks cleanly to the rest of your stack before you commit, and the transition plan sequences the change to minimize disruption. After the decision it still helps, but you’re designing around a fixed constraint. What if the transition plan says we need to change more than we expected?Then you’ll know it with a sequence attached, not as one scary lump of change. The transition plan orders the moves to minimize disruption and front-load early wins, so a bigger transition becomes a series of small, survivable steps rather than everything at once. You also control the pace: the sequence works at your budget’s speed. Do you evaluate the whole stack at once, or focus on the biggest pain points first?It depends on what’s driving the request; if tech costs are growing faster than revenue, we usually start there hunting redundancy. The full evaluation still maps the whole stack, because the expensive problems usually live in the connections between tools, not inside any single one. Starting at the pain point just decides which corner of the map gets drawn first. ## You might also like #### CDP Integration & Data Unification Fragmented data means fragmented decisions.
