What we build

What can AI agents do in SaaS products?

SaaS agents answer questions and take actions inside your product within the user's permissions, deflect support tickets using your documentation with citations, migrate new customers' data from spreadsheets and competitor exports, and run multi-step workflows with admin-inspectable traces.

  1. 01

    In-product copilot

    Answers and acts inside your product, scoped to the tenant's data and the signed-in user's permissions.

  2. 02

    Support deflection agent

    Answers product questions from your documentation with citations, escalating gaps as content requests.

  3. 03

    Onboarding migration agent

    Maps and imports customer data from spreadsheets and competitor exports, flagging ambiguity for confirmation.

  4. 04

    Workflow agent

    Executes multi-step tasks with approval gates and traces the customer's admin can inspect.

    Admin insight agent

    Answers admin questions about usage and configuration from tenant data, with the query shown.

Requirements

What guardrails do SaaS products agents need?

Agents inside a multi-tenant product inherit every tenancy and permission obligation you already carry, plus new ones: cost scales with usage, customers will ask how their data is handled, and a mistake is visible to a paying account immediately.

SaaS: requirements and how FISTA Solutions builds to them
GuardrailWhy it matters hereHow FISTA implements it
Tenant and permission scopingAn agent must never cross tenant or role boundaries.Scoping enforced in the tool layer against the caller's session, with tenant-scoped tests in CI covering agent paths.
Cost per tenantAI usage scales with adoption, not revenue.Per-tenant cost attribution, model routing by task, caching, context discipline, and budgets with alerts.
Customer transparencyEnterprise buyers ask how AI handles their data.Documented data flows, training disabled on enterprise endpoints, region options, and admin-visible traces.
Quality gatesA regression is visible to every customer at once.Golden test set per feature, evaluation in CI, canary rollout by tenant cohort, and instant feature flag rollback.
Graceful failureModel outages must not break the product.Timeouts, fallbacks to non-AI paths, and clear UI states rather than spinners when the model is unavailable.

Where AI fits

Which SaaS products workflow should you automate first?

Start with support deflection grounded in your documentation. It has a measurable baseline in ticket volume, no write access to customer data, and it surfaces exactly where your documentation is weak — which is valuable on its own.

  1. 01

    1. Deflect support with citations

    Read-only, measurable against ticket volume, and it exposes documentation gaps as a by-product.

  2. 02

    2. Add read-only copilot answers

    Let users ask questions of their own data within their permissions before any write capability.

  3. 03

    3. Automate onboarding imports

    Migration is bounded, high-value, and reviewed by the customer before commit.

  4. 04

    4. Introduce approval-gated actions

    Workflow agents that prepare changes an admin approves, with traces they can inspect.

  5. 05

    5. Price it deliberately

    Decide packaging and limits from measured per-tenant cost, before adoption makes the decision for you.

Cost and timeline

How much does an AI agent for SaaS products cost, and how long does it take?

Cost is driven by product surface area, evaluation depth, and inference volume; timeline by how much of your data model is agent-ready. FISTA does not quote blind: the scoping call returns a feature design, a cost model, and a phased estimate.

Inference cost is a product decision, not an infrastructure detail. FISTA models cost per active tenant during design and builds attribution into the feature, so pricing and limits are set with evidence before launch.

Evaluation is what keeps the feature shippable. A golden set per capability, run in CI, is what allows you to change models or prompts later without guessing whether quality moved.

Send the scope you have, even if it is a paragraph. You get a written brief, an architecture sketch, and a phased estimate before any commitment.

Delivery

How does FISTA deliver an AI agent into production?

FISTA delivers agents in four gated phases: a discovery sprint that picks the workflow and writes the agent specification, a design that names tools, permissions, and approval points, a build with an evaluation harness and shadow runs on real work, and a production release with traces, dashboards, and rollback.

  1. 1

    Select and specify

    Choose the workflow with a measurable outcome, map its systems and edge cases, and write the agent spec with success metrics.

    Output

    Agent specification, golden test set

  2. 2

    Design the guardrails

    Tool inventory with least-privilege scopes, approval gates, escalation paths, data handling, and the evaluation plan.

    Output

    Tool and permission matrix

  3. 3

    Build and shadow-run

    Implement tools as MCP servers or connectors, iterate against the evaluation harness, and run in shadow mode on live inputs.

    Output

    Shadow-mode results, eval scores

  4. 4

    Release and observe

    Graduated rollout, full traces, cost and quality dashboards, on-call runbook, and a change process that re-runs the evals.

    Output

    Production agent with SLOs

Why FISTA

Why choose FISTA Solutions to build your SaaS products agents?

FISTA builds product AI with tenancy enforced in the tool layer, cost attributed per tenant, and evaluation gating every release. Work happens inside your repositories and CI, contracted through a US entity with full IP assignment.

SaaS specifics

  • Tenant and permission scoping is enforced where tools execute, not merely described in a prompt.
  • Per-tenant cost attribution ships with the feature, so gross margin is visible alongside adoption.
  • Golden-set evaluation runs in CI, with canary rollout by cohort and instant rollback behind a flag.
  • Data flows are documented for your customers' security reviews, with training disabled on enterprise endpoints.

How FISTA engineers

  • Spec-Driven Development: every deliverable starts as a written specification with acceptance criteria, so scope is testable before it is built.
  • AI-native delivery: engineers direct coding agents under review gates and evaluation harnesses, compressing build time without loosening verification.
  • Official Anthropic partner, with production experience across Claude, OpenAI, Google, and open-weight models, chosen per workload rather than by default.
  • One accountable delivery lead, weekly demos on your environment, and code in your repositories from week one.

What you get as a client

  • 150+ projects delivered for 50+ companies across 12+ countries since 2017, with 99.9% verified uptime on systems we operate.
  • A US entity (FISTA Solutions Inc., Wilmington, Delaware) for contracting, invoicing, and IP assignment, with an engineering center in Faisalabad, Pakistan for cost-efficient senior capacity.
  • US business-hours overlap for standups and reviews; written decision logs so nothing depends on a meeting you missed.
  • Flexible engagement: fixed-scope build, embedded forward deployed engineers, or a dedicated team that you can scale month to month.

Clear answers

What teams ask before deploying agents.

Straightforward guidance for evaluating scope, fit, and the next step.

01How do you stop an agent from leaking another tenant's data?

Scoping is enforced where the tools execute, using the caller's session rather than model instructions, and tenant-scoped tests in CI cover agent paths specifically. The isolation model is documented for your customers' security reviews.

02How do we keep AI features from eating our margin?

Per-tenant cost attribution is built into the feature, with model routing by task, caching, context discipline, and budget alerts. Pricing and usage limits are then set from measured data rather than guesses.

03What happens when the model provider has an outage?

The feature degrades to a non-AI path with a clear UI state. Timeouts and fallbacks are designed in, because an AI feature that hangs makes the whole product feel broken.

04Can you work inside our existing codebase?

Yes. FISTA works in your repositories, CI, and review process, and starts with an assessment of whether the data model and permission layer are ready for agent access.

05How fast can we ship an AI feature?

A grounded support or copilot feature typically reaches beta within weeks and general availability within a quarter, depending on data readiness and evaluation depth. Discovery scopes both.
