Engineering for B2B SaaS That Scales
Multi-tenant architectures, complex integrations, and workflow automation. We help vertical SaaS companies ship faster without compromising on the depth that makes your product valuable.
B2B SaaS isn't consumer tech with a pricing page. Your customers demand customization, integrations, compliance, and reliability. We build the engineering foundations that let you deliver enterprise-grade software without an enterprise-sized team.
Book a CallThe engineering challenges killing B2B SaaS growth
Every enterprise customer wants something custom
Your biggest customers need custom fields, custom workflows, custom integrations. Your product wasn't designed for this level of configurability, so every customization request becomes a feature branch that never merges. You're building n products instead of one.
Your integration backlog is 6 months long
Salesforce, HubSpot, Slack, custom APIs — every deal requires an integration you don't have. Your competitors win because they connect to the customer's existing stack. You lose because "it's on the roadmap."
Multi-tenancy is an afterthought
You started with single-tenant deploys because it was easier. Now you're managing 50 separate instances, each slightly different. Infrastructure costs are 5x what they should be, and one customer's bug is everyone's emergency.
Your dev team can't keep up with product ambitions
You have 200 features on the roadmap and 5 engineers. Every quarter, you ship 10% of what you promised. Your churn rate reflects it. You need to double your engineering output without doubling your burn rate.
What we build for B2B SaaS companies
Engineering that turns your product into a platform customers build their business on.
Multi-Tenant Architecture
Proper multi-tenancy: data isolation, tenant-specific configurations, feature flags, usage-based billing, and performance isolation. One codebase that serves every customer correctly.
Integration Platform & APIs
RESTful and GraphQL APIs, webhook systems, OAuth integrations, and embedded iPaaS capabilities. Turn your integration backlog into a competitive advantage with a platform approach.
Workflow Automation Engine
Configurable workflow builders, rule engines, and automation systems that let customers customize behavior without engineering effort. The flexibility enterprises demand, built once.
Admin & Analytics Dashboards
Customer-facing analytics, admin panels, usage dashboards, and reporting tools. Self-service capabilities that reduce support tickets and increase product stickiness.
Billing & Subscription Infrastructure
Usage-based billing, tiered pricing, seat management, and enterprise invoicing. Integrated with Stripe, Chargebee, or custom solutions that match your go-to-market.
Security & Compliance
SOC 2 readiness, SSO/SAML integration, role-based access controls, audit logging, and data residency. The table-stakes security that enterprise buyers require before signing.

How we scale B2B SaaS products
Product & Architecture Review
We analyze your current product architecture, technical debt, and growth bottlenecks. We identify what's blocking your next stage of growth and create a prioritized engineering plan.
Foundation Strengthening
We fix the architectural issues that slow everything else down: proper multi-tenancy, API design, testing infrastructure, and deployment automation. This phase unblocks everything after it.
Feature Velocity
With the foundation solid, our embedded engineers join your team to accelerate feature delivery. Sprint-by-sprint, we ship the features your customers and prospects are waiting for.
Platform Maturity
We build the platform capabilities — integrations, automation, extensibility — that turn your product from a tool into the system of record your customers can't live without.
Why Pletava
We've scaled SaaS products before
Our engineers have built multi-tenant platforms serving thousands of companies. We know the architecture patterns that work at 10 customers and still work at 10,000.
Product-minded engineers
We don't just ship features — we understand unit economics, churn drivers, and what makes enterprise buyers sign. Our engineers ask "why" before writing code.
Embedded, not outsourced
Our engineers work in your repos, attend your standups, and debate architecture in your Slack. They're your team — we just handle the hiring, payroll, and retention.
Frequently Asked Questions

Book a CallCan you help us move from single-tenant to multi-tenant?
Yes. We've done this migration multiple times. We use an incremental approach — shared services first, then data isolation, then full multi-tenancy — so you never stop shipping features during the transition.
What stage SaaS companies do you work with?
From seed-stage startups building their MVP to Series B+ companies scaling to enterprise. Our engagement model adapts: embedded engineers for early-stage, larger teams for growth-stage.
How quickly can engineers start contributing?
Most of our engineers ship their first meaningful PR within the first week. By week two, they're fully integrated and contributing at the pace of your best team members.
Do you handle DevOps and infrastructure too?
Yes. Full-stack means full-stack: frontend, backend, infrastructure, CI/CD, monitoring, and security. We don't stop at the application layer.
