Cybersecurity Consult

Pragmatic security — budget-aware and board-ready.

Threat-modelIAMSASTReview
Timeline
2 – 6 weeks

Security consulting that ignores commercial reality is useless. We threat-model your actual attack surface — not a theoretical enterprise — and we prioritise findings by exploitability, impact, and remediation cost.

We use STRIDE and MITRE ATT&CK as frameworks, not cargo cult. Every recommendation comes with a Jira-ready ticket, a risk rating, and a clear rationale for why it matters now versus later.

We work particularly well with Series A–C companies preparing for SOC 2, ISO 27001, or enterprise sales due diligence. We know what auditors look for and we help you get there without over-engineering the controls.

Penetration Testing

Find the holes before your adversary does.

OWASPReconReportRetest
Timeline
1 – 4 weeks per engagement

We offer black-box, grey-box, and continuous penetration testing engagements. Scope is agreed in advance — web applications, APIs, mobile, cloud infrastructure, or a combination — and every test is conducted with a signed rules of engagement.

Our reports are written for engineers. Every finding includes: the vulnerability class, the reproduction steps, the business impact, a CVSS score, and a concrete remediation recommendation with code snippets where applicable. No 200-page PDFs of NIST references.

We offer a free retest within 60 days of the original engagement. If a finding we flagged hasn't been remediated, you'll know. If it has, you'll have written evidence for your next audit.

Website Security

Always-on protection for production properties.

WAFCSPDDoSHeaders
Timeline
Ongoing — monthly retainer

Retainer-based security hardening for sites and apps that can't afford downtime. We configure, monitor, and continuously harden your production environment — WAF rules, security headers, DDoS mitigation, runtime anomaly detection.

We start with a baseline assessment: headers audit (CSP, HSTS, X-Frame-Options, Permissions-Policy), third-party script inventory, cookie security, CORS configuration, and infrastructure exposure. Then we remediate and set alert thresholds.

Monthly reporting covers: blocked requests by category, new third-party scripts detected, header compliance score, and any triggered anomalies. Quarterly we re-run the baseline and measure drift.

Technical Consulting

A senior technical voice — without the full-time hire.

ArchitectureDDHiringVendor
Timeline
Project or retainer basis

We embed as fractional CTO, technical advisor, or architecture reviewer depending on what you actually need. We've helped founders choose between three database vendors, helped VCs evaluate the technical risk in a target acquisition, and helped Series B companies plan a platform migration without losing the team doing it.

Technical due diligence is a specific specialty. We review codebases, interview engineering leads, assess infrastructure, and produce a structured report that goes beyond 'the code is messy' to quantify the actual remediation cost.

Architecture reviews are structured as half-day workshops with your senior engineers followed by a written decision record. Not a slide deck — a document your team can act on six months from now.

Next.js Development

The framework that ships — and stays fast.

Next 15RSCEdgeVercel
Timeline
4 – 16 weeks

We've shipped over 40 Next.js platforms since App Router hit stable. Every engagement starts with the same foundation: TypeScript strict mode, RSC by default, edge-ready deployment, and a Lighthouse score that holds under real-world load.

We don't bolt performance on at the end. ISR strategies, image pipelines, font subsetting, bundle analysis — these are first-class decisions made at architecture review, not afterthoughts in a post-launch panic.

Every codebase we hand back comes with a runbook, observability hooks, and a CI pipeline your team can actually understand.

Deliverables
App Router architecture
Server & Client component map
ISR / SSG strategy
Edge function config
CI/CD pipeline

MERN Applications

Full-stack, typed end-to-end, production-ready.

NodeReactMongoRealtime
Timeline
6 – 20 weeks

MongoDB, Express, React, Node — the stack that built the modern web. We've rebuilt enough legacy MERN apps to know exactly where they rot, and we build new ones to avoid every one of those failure modes.

We default to TypeScript across the entire stack. Zod for runtime validation at every boundary. Prisma or Mongoose depending on your access patterns. JWT or session auth with refresh-token rotation baked in from day one.

Realtime? WebSocket bridging via Socket.io or Server-Sent Events for streaming. Payments? Stripe with webhook idempotency. Multi-tenant? Row-level security with organization isolation. We've done all of it.

Deliverables
TypeScript monorepo setup
REST or tRPC API layer
Auth with RBAC

SaaS Platforms

From v0 to scale — without the architectural regret.

Multi-tenantStripeRBACAudit
Timeline
8 – 24 weeks

Most SaaS platforms we inherit have the same problems: a single-tenant data model bolted into a multi-tenant product, Stripe billing wired in at the last minute, and an admin panel that crashes if you look at it wrong.

We solve this at the architecture stage. Multi-tenant from row one. Organization isolation enforced at the query layer. Billing modeled properly — plans, seats, usage metering, invoice generation — before a single product screen is built.

Every SaaS we ship includes an admin workspace, audit logging, feature flags, usage dashboards, and the observability hooks to know what's breaking before your first enterprise customer calls.

Stripe billing + metering
Admin workspace

UI / UX Design

Design that converts — measured and proven.

ResearchSystemsFigmaTokens
Timeline
3 – 10 weeks

We don't design in a vacuum. Every engagement starts with a discovery sprint: user interviews, heatmaps, funnel analysis, competitive teardowns. We form a hypothesis before we open Figma.

Lo-fi wireframes get validated fast — with real users if the budget allows, with the founding team if it doesn't. Hi-fi arrives when the structure is locked, not when the clock runs out. Motion is the last 10% that makes the first 90% feel intentional.

We hand off design as tokens, components, and documented interaction patterns. Not a 200-frame Figma file your engineers have to reverse-engineer. Production-ready design for production-ready engineers.

Deliverables
User research synthesis
Information architecture
Lo-fi → hi-fi flows
Design system + tokens
Component library (Figma)
Motion spec + prototype

Brand & Identity

Identity built for the surfaces where it actually lives.

IdentityVoiceMotionGuidelines
Timeline
4 – 12 weeks

A brand that only exists on a brand board is not a brand. We build identity systems that work at 16px in a browser tab, at 320px on a phone, and at 16 feet on a conference banner.

We start with a naming and positioning workshop if the brand is new. For rebrands, we audit what's working and what's become invisible. Then: wordmark, logotype, typographic system, colour palette, illustration style, motion language, and voice guidelines.

We don't stop at the PDF. We implement the identity — component library, Figma library, Webflow or Next.js site, social templates. Brand as a living system, not a document.

SEO Optimization

Technical SEO that engineering teams can actually execute.

TechnicalContentCWVSchema
Timeline
Ongoing — 90-day sprints

Most SEO audits produce a spreadsheet nobody acts on. Ours produce a prioritised engineering backlog mapped to revenue impact, each with a reproducible test so you know when it's done.

Technical first: crawlability, canonical structure, schema markup, sitemaps, hreflang (if international), Core Web Vitals per page. Then content: keyword clustering, internal linking architecture, pillar-and-cluster strategy. Then measurement: custom GA4 / Search Console dashboards that tell you if the work is moving the needle.

We operate on 90-day sprints with monthly reporting. Every sprint has a declared success metric. We kill what doesn't work.

Core Web Vitals remediation

Digital Marketing

Acquisition that scales — not spend that inflates.

PaidLifecycleCROAttribution
Timeline
Ongoing — monthly retainer

We're channel-agnostic because your buyers are. We start by mapping your highest-intent acquisition paths — organic, paid, referral, email — and we measure each against LTV, not just CPA.

Paid: Google, Meta, LinkedIn. We write our own copy, build our own creative briefs, and maintain separate brand and performance campaigns. Attribution is set up properly from day one — first-touch, last-touch, and data-driven where the volume allows.

Lifecycle: welcome sequences, activation nudges, churn-prevention flows. We use Klaviyo, Customer.io, or Postmark depending on your product complexity. Every flow is A/B tested and documented.

Deliverables
Attribution model + tagging
Paid campaign setup + creative
Lifecycle email architecture

Social Growth

Content engines that compound — not posts that disappear.

EditorialCreatorStrategyDistribution
Timeline
Ongoing — monthly retainer

Vanity metrics are easy to inflate and useless to measure. We build editorial systems with a single objective: compounding reach on the platforms your buyers actually use.

That means a documented content strategy — pillars, formats, cadence — tied to your commercial goals. It means a production system your team can operate without agency dependency. And it means distribution: newsletters, repurposing frameworks, creator collaborations that actually convert.

We've built content engines for SaaS, fintech, e-commerce, and professional services. The formats differ. The underlying system — create once, distribute everywhere, measure ruthlessly — never does.

Creator collaboration framework
Newsletter setup + templates

Email Marketing

Lifecycle email that converts — not just hits the inbox.

KlaviyoLifecycleDeliverabilitySegments
Timeline
Ongoing — monthly retainer

We architect lifecycle email from segmentation outward: welcome, onboarding, activation, retention, win-back. Every flow gets a measurable success metric and a documented exit criteria — so we know when a flow is done and when it needs iteration.

Deliverability is the unglamorous half of email. We configure SPF, DKIM, DMARC, BIMI; warm new sending IPs properly; segment by engagement to protect sender reputation; and report inbox placement (not just delivered) every month.

Tooling — Klaviyo, Customer.io, Postmark, Resend — chosen by data volume and product complexity, not vendor relationships. Templates designed in code so engineering can iterate without waiting on a designer.

Content Marketing

Content engineered to rank, convert, and compound.

PillarClusterEditorialTopical
Timeline
Ongoing — quarterly sprints

Content marketing without strategy is just publishing. We start with topical authority mapping — what your buyers search, what your competitors rank for, where the gaps live — and build a pillar-and-cluster architecture that signals topical depth to search engines and humans alike.

Long-form is the centre of gravity: 2,000–4,000-word pieces that answer commercial-intent queries with the depth a 600-word post can't. Each pillar gets supporting cluster posts, internal linking, and schema markup so the topical structure is machine-readable.

We write with subject-matter experts on your team — not in a vacuum. Briefs go through your reviewer, drafts come back with citations, and every piece ships with a 90-day measurement plan tied to organic traffic and demo conversions.

Deliverables
Topical authority audit
Pillar-and-cluster architecture
Editorial calendar + briefs
Long-form writing + editing
Internal linking framework
Quarterly organic performance review

Conversion Optimization

Move the metric that pays the bills.

A/BFunnelsHeatmapsHypothesis
Timeline
Ongoing — monthly retainer

CRO is not about button colours. It's a disciplined hypothesis-led process: identify friction with quantitative analytics and qualitative session replay, write falsifiable hypotheses, run statistically valid tests, ship what wins, document what loses.

We instrument first — GA4, Mixpanel, PostHog, Hotjar — so we can see funnel drop-off, scroll depth, rage clicks, and form abandonment. Then we run a discovery sprint: user interviews if budget allows, founder/CS interviews if it doesn't. Test backlog is prioritised by ICE (Impact, Confidence, Ease).

Every test ships with a pre-registered MDE, success metric, and decision rule. We don't keep tests running until they 'look significant.' We document every losing test alongside the wins — they're more valuable for learning than the wins are.

Deliverables
Funnel diagnostic + heatmaps
Test backlog (ICE-prioritised)
Hypothesis docs + experiment design
Implementation in GTM / A/B platform
Statistical analysis + decision memos
