Website Personalization Software Development

Website personalization software built on the visitor data you already have

Most B2B personalization is IF/THEN segment logic once you have your own visitor and account data flowing in. We build a custom personalization layer directly on your existing analytics and CRM stack, instead of you paying seat licenses for a point tool that duplicates data you already own.

  • Custom segment and rules logic built on your own visitor and account data

  • Direct integration with your existing analytics, CRM, and CDP stack

  • A/B and multivariate testing built into the same layer as personalization

  • Fixed-cost delivery, scoped up front, with source code ownership

The problem

Sound familiar?

  • Paying per-seat for a personalization platform when only one or two people actually configure it?

  • Rebuilding the same account and firmographic data in a point tool that your CRM already has?

Short answer

Website personalization software changes what a visitor sees, headlines, offers, calls to action, based on who they are or how they behave, and it overlaps closely with conversion rate optimization (CRO) tooling used for A/B and multivariate testing. Companies buy it when they want different experiences for different accounts or segments without hand-coding every variant. RaftLabs builds this as a custom layer on top of a company's existing analytics and CRM data instead of a licensed platform: an MVP with segment logic and rules-based personalization runs $20,000-$50,000 over 12-15 weeks, and a full build with deeper A/B testing and account-based logic runs $50,000-$100,000 over 15-18 weeks, at a fixed cost.

Key takeaways

  • Most B2B personalization is IF/THEN segment logic once a company has its own visitor and account data flowing into one place.
  • A custom layer built directly on an existing analytics and CRM stack avoids re-collecting data a licensed point tool would ask you to duplicate.
  • Segment logic, A/B testing, and personalization rules can live in one system instead of three separate subscriptions.
  • A full build with account-based logic and testing infrastructure typically takes 15-18 weeks at a fixed, agreed cost.

Personalization logic isn't the hard part. Owning your own data is

Once visitor and account data lives in one place, most B2B personalization comes down to segment rules: if this account fits this profile, show this variant. Licensed platforms charge per seat to run that logic on top of data your analytics and CRM already hold. We build the logic directly on the stack you already have.

Capabilities

What we build

  • 01
    Segment and rules-based personalization

    IF/THEN logic that changes headlines, offers, and calls to action by account, firmographic profile, or behavior, built on the visitor data your stack already captures.

  • 02
    Direct CRM and analytics integration

    Personalization rules read from your existing CRM, analytics, and CDP instead of asking you to re-import or duplicate account data into a separate tool.

  • 03
    A/B and multivariate testing

    Testing infrastructure built into the same layer as personalization, so a variant can be tested before it's rolled out as a rule.

  • 04
    Account-based visitor identification

    Matching anonymous and known visitors to account records, so personalization can key off company, not just individual, behavior.

  • 05
    Conversion rate reporting and analysis

    Reporting on which segments and variants convert, built on your own data warehouse instead of a vendor's locked-in dashboard.

  • 06
    Rollout and rule management tooling

    An internal interface for marketing to add and edit segment rules without engineering involvement after launch.

How we work

From data audit to live personalization

  1. Weeks 1-3
    01

    Discovery and data audit

    We map what visitor and account data you already have across analytics, CRM, and CDP, and what personalization logic you actually need. You leave with a written scope and a fixed-price quote.

  2. Weeks 3-6
    02

    Segment logic and integration design

    We design the segment rules, the integration points into your existing stack, and the testing framework alongside them.

  3. Weeks 6-14
    03

    Build in two-week sprints

    You review working software at each sprint. Segment logic, integrations, and testing tooling are built and tested incrementally.

  4. Final 2-4 weeks
    04

    Rollout and rule handoff

    The system runs against live traffic so your team can validate variant behavior, then we hand off the rule-management interface so marketing can run it day to day.

Frequently asked questions

Website personalization software changes the content, headlines, offers, or calls to action a visitor sees based on who they are or how they've behaved on the site. It's closely related to conversion rate optimization (CRO) tooling, which runs the A/B and multivariate tests that personalization decisions are often based on.

Yes. Most B2B personalization comes down to segment logic, IF this account or visitor type, THEN show this variant, once your visitor and account data is flowing into one place. We build that logic directly on your existing analytics and CRM stack during discovery.

Yes. Testing infrastructure and personalization rules can live in the same custom layer, so you're not running one subscription for testing and a separate one for personalization.

An MVP with segment logic and rules-based personalization typically runs $20,000-$50,000 and takes 12-15 weeks. A full build with deeper A/B testing and account-based logic runs $50,000-$100,000 over 15-18 weeks. We scope a fixed cost after discovery.

Established platforms like Mutiny, Optimizely, and VWO are strong tools for standard A/B testing and common account-based use cases, and they get you started fast. Custom software makes sense when your personalization logic is tied to proprietary data your CRM or analytics stack already holds, and you'd rather build directly on that data than pay seat licenses to duplicate it in a point tool. We help assess the right fit during discovery.
