Bespoke business software · since 2026

Made to measure.

We design and run private software for owners who refuse to bend their business around someone else's tool. The dashboards, the workflows, the AI in the background — all of it shaped to how you actually work, then run by us so you never have to think about the tech.

The promise

Four things we never compromise on.

Most software firms sell you a platform and bill you for the customizations. We sell the customization itself — and the team that runs it. Here's what that means in practice.

On fit

Software shaped to your business — not the other way around.

You shouldn't be the one bending. Off-the-shelf tools force you into someone else's workflow; we map yours and build for it. Your terminology, your steps, your edge cases.

On craft

Built by people who care how it ends, not just how it ships.

Every dashboard, every form, every email template gets the same attention as a private commission should. Slow where it matters. Fast where it doesn't.

On running it

We don't hand you the keys and disappear.

The software is ours to maintain. Bugs, updates, new features, integrations — we run it as your operations team, not as a vendor with an SLA.

On AI

Quietly, where it earns its keep. Never as a gimmick.

AI is woven in where it saves you time — drafting emails in your voice, handling inbound, summarizing meetings, watching for edge cases. You never see a prompt or an API key. We do the technical work.

What we build

Six disciplines we've made our own.

Every project starts with the smallest piece that solves your biggest problem, then expands from there. These are the disciplines we draw on — picked, blended, and tuned for what your business actually needs.

i.

Sales & reporting

Live dashboards tuned to your business — what's selling, what isn't, where margin is leaking. Not Shopify defaults; your slices.

ii.

Customer relationships

A CRM built around how your team actually sells — pipelines that match your cycle, notes where you need them. No Salesforce tax.

iii.

Email & marketing

Newsletters, drip sequences, win-backs, abandoned cart — generated, scheduled, tracked. AI drafts in your voice; you approve and send.

iv.

Inventory & operations

Reorder alerts before stock-outs, run-rate forecasts that account for seasonality, PO workflows that don't need a spreadsheet to keep them honest.

v.

AI, ready to run

An assistant trained on your products, policies, and tone — handling 60–80% of inbound, drafting in your voice. You never see a prompt.

vi.

Integrations & web

Shopify, Square, QuickBooks, Stripe, Klaviyo, your supplier portal, your marketing site — connected so data flows once and shows up everywhere.

… and a hundred smaller things — quote builders, internal tools, dashboards for your accountant. Tell us what you need →

A look at what we ship — dashboards, marketing sites, AI agents — all running for owners who never wanted to become developers.

A working partnership

We don't sell you a platform — we become part of your team.

Most software vendors deliver and disappear. We deliver, stay on, and run the thing — adding features, monitoring AI agents, fixing the unexpected. One team, for the whole stack.

How we work

Four phases. Designed not to waste your time.

No 90-day discovery phase, no bloated SOWs. We start with the smallest thing that solves your biggest problem — and ship fast.

i.

Discover

One sixty-minute call. We map how your business actually runs today — the spreadsheets, the workarounds, the Sunday-night rituals.

~ 1 hour
ii.

Design

Within a week, you get a working clickable prototype. We iterate until it feels right, not until the spec document is finished.

~ 7 days
iii.

Build

Two to four weeks to the first deployed version. Real data, real workflows, a backend you own outright. No platform lock-in.

2–4 weeks
iv.

Run

We stay on as your operations team — adding features, monitoring AI agents, handling integrations as your business grows.

Who's behind this

A studio, not an agency funnel.

Slytherin is run by Ankit Bhasin under his studio, OpenClaw, out of New York. When you write in, you're talking to the person who scopes the work, designs the software, and stays on to run it — not a sales team handing you off to an offshore queue.

That's the whole model: small, accountable, and on the hook for how it ends. You own the code and the data outright — if you ever leave, all of it goes with you. No platform lock-in, no surprise license, no black box.

How we actually work

  • One free 20-minute call first. No deck, no obligation. If we're not the right fit, we'll say so — and point you to who is.
  • A working prototype before a contract. You see something real within seven days, not a 90-day discovery invoice.
  • Quoted up front. Most engagements run roughly $15K–$80K over 4–12 weeks. The exact number is agreed before any work begins.
  • We run it after we build it. Maintenance, new features, and the AI in the background are ours to keep healthy — not a hand-off-and-vanish.

Case in point · B2B supplier

It replaced four tools, two spreadsheets, and a part-time admin — and runs itself.

A family-run packaging supplier. Two state catalogs, ~80 SKUs each, a sales team that opened fourteen tabs every morning. We built one dashboard — sales, CRM, inventory, AI-drafted newsletters, abandoned-cart recovery — and now run it as their operations team.

Questions, answered

The things owners ask before the call.

What does Slytherin build?

Custom business software, built and run for the owner: sales and operations dashboards, CRMs, AI customer-service assistants, email and marketing automation, inventory and reordering tools, and integrations across Shopify, Square, QuickBooks, Stripe, and Klaviyo. Every build is shaped around how your specific business works — not the other way around.

How is bespoke software different from off-the-shelf SaaS?

Off-the-shelf SaaS makes you adapt your workflow to the tool, then bills you for every customization. Slytherin builds the software around your existing process — your terminology, your steps, your edge cases — and then runs it for you. No platform tax, and no becoming a developer to keep it alive.

Do I own the software and data?

Yes. You own the code Slytherin writes for you and all of your data outright. There's no platform lock-in — if you ever leave, the software and data go with you.

How long until I see something working?

A working clickable prototype typically arrives within seven days of the first call, with the first deployed version in roughly two to four weeks. There's no 90-day discovery phase — Slytherin starts with the smallest piece that solves your biggest problem.

What does it cost, and is the consultation really free?

The initial 20-minute consultation is always free — no pitch deck, no obligation. Most engagements run roughly $15K–$80K over 4–12 weeks, depending on scope, with the exact figure quoted up front before any work begins. No sign-up-then-discover-the-price.

Who is behind Slytherin, and who do you work with?

Slytherin is an OpenClaw studio founded by Ankit Bhasin, based in New York, NY. Slytherin works with small and mid-size businesses across the United States — B2B suppliers, e-commerce brands, boutique hotels, service businesses, and restaurants.
