UPSTREAM · B2B SAAS STACK REBUILD
For B2B SaaS · $20M–$500M ARR · 50–500 employees

HubSpot + Intercom + Sentry + Mixpanel.
Four wrappers. One rebuild.

The standard B2B SaaS ops stack typically costs $180K–$400K/yr at mid-stage — and 70–85% of that is wrapper margin over commodity primitives (AWS SES, Anthropic, ClickHouse, Postgres). We rebuild all four on direct billing in one bundled engagement. One project. One contract. One ship date.

What each of the four tools wraps

Four wrappers. Same primitives.

Each tool in the standard B2B SaaS ops stack wraps a commodity primitive. HubSpot on AWS SES + Postgres. Intercom on a chat engine + LLM. Sentry on ClickHouse (Sentry IS open source). Mixpanel on event-storage primitives. We have dedicated rebuild pages for each — the numbers are deeper there.

Bundled engagement amortises rebuild costs across 4 tools — net Y1 reclaim is greater than the sum of separate rebuilds. See the bundle math below.

Bundle vs separate engagements

Why all four at once beats four sequential.

Three reasons the bundle costs ~70% of four separate rebuilds, ships in ~50% of the calendar time, and produces a more cohesive operational result.

Unified data layer — no glue code, no per-event Segment fee

Many teams start with one rebuild (typically Sentry, since the math is sharpest) and add modules later. That works — bundle pricing applies if you commit to the full set within 6 months.

What you end up with

One unified ops stack. Four modules.

Marketing, Support, Observability, Analytics — sharing your AWS account, your Postgres, your auth layer. Cross-module data flows natively, no Segment/Hightouch integration overhead.

Bundle pricing

Fixed price. All four modules.

One contract, one ship date, one team running the engagement. Bundle pricing assumes all four modules ship together; à-la-carte pricing per tool is on each individual rebuild page.

Questions about a bundled B2B SaaS rebuild

"What if…"

Can we sequence the rebuild instead of all at once?
Yes. Many teams start with the sharpest-math line item (often Sentry — open source, fast payback) and add modules within 6 months. Bundle pricing applies if you commit to the full set within 6 months. Outside that window each rebuild is priced individually.
Which order makes the most sense?
Lowest-risk-to-team first. Typical order: (1) Sentry (no user-facing change, fastest payback), (2) Mixpanel (analytics teams adapt fastest), (3) HubSpot (marketing-led migration), (4) Intercom (most user-facing, highest stakes — last). Each cutover gets a 2-week pilot before the next starts.
What if we use Zendesk + Pardot instead of Intercom + HubSpot?
Same bundle price for Zendesk, +$8K for Pardot. We rebuild whichever stack you actually run. Zendesk Pro at 50 agents + Pardot Plus at 25K prospects is the most common alternative configuration; we've done both rebuilds at the same combined price.
What about Datadog / observability beyond Sentry?
Sentry covers errors + performance + replay. If you also pay for Datadog APM / Logs / Infrastructure ($30K+/yr), we add a Grafana + Prometheus + Loki module to replace those. +$14K–$22K to the bundle; pays back inside Y1 at typical Datadog spend.
What about Segment / Rudderstack / customer data platform?
Most teams use Segment to glue HubSpot ↔ Mixpanel ↔ Intercom data together. In our bundled rebuild, that data flow is native — your Postgres is the source of truth, all modules read/write it. Segment becomes optional, often droppable entirely.
What's the team migration burden?
Less than four separate vendor migrations. Reasons: (1) unified UX — one auth, one nav, one data model; (2) we run it as Managed Upstream if you'd prefer not to host (~$12–18K/yr); (3) no surprise renewals, no per-resolution / per-MTU / per-event escalations.
What about SOC 2 / HIPAA / compliance?
Deployed on your AWS account inherits AWS's SOC 2, ISO 27001, HIPAA-eligible posture. We provide control documentation as part of delivery. Stronger posture than running 4 separate SaaS vendors — fewer subprocessors in your data-handling chain.
Who owns the code?
You. Pushed to your GitHub from day one. Allied BizTech retains no rights and no copy. Docker-portable infrastructure runs on AWS, GCP, Azure, or your on-prem.
