I Cut My LLM API Costs by 60% With One Line of Code

Jenavus — Fri, 27 Mar 2026 11:31:51 +0000

I was spending $1,200/month on AI API calls. When I audited where the money was going, I found that 70% of my requests were going to GPT-4 — for tasks that a much cheaper model could handle just as well.

Email summaries? Doesn't need GPT-4.
Ticket classification? Doesn't need Sonnet.
Extracting a name from text? Definitely doesn't need a $0.03/request model.

The Problem

Most AI apps send every request — even simple ones — to the most expensive model. That's like taking a taxi to your mailbox.

Task	Without TokenRouter	With TokenRouter
"Summarize this email"	GPT-4o ($0.03)	Haiku ($0.001)
"Classify this ticket"	Claude Sonnet ($0.01)	Flash ($0.0005)
"Extract this name"	GPT-4o ($0.02)	Local model ($0.00)
"Analyze this contract"	GPT-4o ($0.08)	Stays on GPT-4o ($0.08)

The Solution

I built TokenRouter — an OpenAI-compatible proxy that sits between your app and your AI provider.

It classifies each request by complexity and routes it to the cheapest model that can do the job:

Simple tasks (extraction, classification) → cheapest available model
Medium tasks (summaries, Q&A) → mid-tier
Complex tasks (legal analysis, coding) → premium model

How It Works

Change one line of code — your base URL:

# Before
client = OpenAI(api_key="sk-...")

# After
client = OpenAI(api_key="sk-...", base_url="https://tokenrouter.jenavus.com/v1")

That's it. Your existing code works unchanged. TokenRouter handles the routing automatically.

Results

60% average cost reduction
Zero quality loss — complex tasks still go to premium models
Automatic fallback — if a model is down, it switches instantly
Real-time cost dashboard — see exactly where every dollar goes

RecoverFlow — Stripe dunning that actually works—for $19/mo.

Jenavus — Tue, 24 Mar 2026 16:27:19 +0000

The Problem

SaaS founders lose ~9% of monthly revenue to failed card payments, but existing recovery tools like Churn Buster cost $249/mo—way too expensive for small teams. You're bleeding hundreds or thousands monthly while overpaying for features you don't need, and you have no visibility into exactly how much money is slipping away.

What We're Building

RecoverFlow automatically detects failed payments on Stripe, sends intelligent retry emails on a smart schedule, and recovers lost revenue with zero setup friction. Connect your Stripe account, see your actual leakage in real-time, and watch recovery rates climb—all for $19/mo at startup scale.

Who It's For

Bootstrapped SaaS founders and indie developers running on Stripe with $10k–$100k MRR losing $500+ monthly to failed payments. Works for: SaaS, subscription software, digital products, coaching platforms.

Key Features (Planned)

Real-time Stripe webhook integration—detects failed payments instantly
Visual leakage dashboard—see exactly how much MRR you're losing
Smart retry scheduler—optimal timing reduces card decline rates by 30–50%
Pre-built email templates—or customize your own recovery messages
Stripe OAuth login—no API keys, no manual setup required
Recovery analytics—track success rates and revenue recovered

We're validating this idea before writing a single line of code. If this resonates with you, we'd love your feedback:

How much revenue do you think you lose monthly to failed card payments? And would you switch dunning tools if it cut your bill by 90%?

CarrierShield — Transparent VoIP compliance. No black boxes. No upsells.

Jenavus — Mon, 23 Mar 2026 15:56:19 +0000

The Problem

VoIP carriers like Flowroute use opaque automated compliance systems that lock accounts without explanation, offer no appeal process, and then aggressively upsell replacement plans. Resellers and infrastructure managers managing customer phone lines are left with zero recourse, no visibility into why they're flagged, and impossible migration paths when accounts are killed.

What We're Building

CarrierShield is a transparent VoIP carrier dashboard for resellers that puts compliance decisions in your control. Every account flag gets a human review with a detailed decision log, a formal appeal process, and an export-and-migrate tool that lets you port your DIDs cleanly. You see exactly why you're flagged, can contest it, and can leave without friction.

Who It's For

VoIP resellers, 3CX integrators, and telecom consultants managing 10+ customer accounts at mid-market carriers. Primarily solo operators and small teams (1–5 people) earning $50k–$500k annually from VoIP infrastructure.

Key Features (Planned)

Human review of every compliance flag with transparent decision logs
Formal appeal process and dispute workflow for wrongful terminations
One-click DID export and port request assistant for clean migration
Simplified account cancellation (no friction, no calendar invites)

We're validating this idea before writing a single line of code. If this resonates with you, we'd love your feedback:

If a VoIP carrier gave you full transparency on why your account was flagged and a real appeal process, would you switch from Flowroute?

PrivApp — Elevate legacy apps, not user permissions.

Jenavus — Mon, 23 Mar 2026 07:25:58 +0000

The Problem

Enterprise IT teams running legacy IE/ActiveX clients face an impossible choice: either grant standard users local admin rights (creating massive security exposure) or deploy expensive enterprise PAM solutions ($100k+/year) that are overkill for per-app elevation. Current workarounds like Task Scheduler tricks are fragile, undocumented, and don't scale across hundreds of users without introducing security blind spots.

What We're Building

PrivApp is a lightweight Windows service that enables granular, auditable privilege elevation for specific applications without granting users admin rights. Administrators define which apps (and which users) can elevate via Group Policy; execution is logged centrally; no password sharing or admin credential exposure. Deploy via MSI + GPO in under 30 minutes.

Who It's For

IT Security & Systems Administrators at mid-market enterprises (1,000–10,000 employees) in regulated industries: financial services, manufacturing, utilities, healthcare. Specifically: teams managing legacy SCADA, IoT controllers, or database clients that require elevated permissions.

Key Features (Planned)

Per-app privilege elevation rules via Group Policy—no user admin rights needed
Centralized audit logging of all elevation events to Event Viewer or syslog
Signed execution wrapper with SDDL-based access control—define exactly which users can elevate which apps
Deploy via MSI + GPO in under 30 minutes; works with Windows 7 SP1 and later

We're validating this idea before writing a single line of code. If this resonates with you, we'd love your feedback:

If you're currently managing legacy apps that demand admin rights, how many users are affected, and what's your current workaround costing you in time/security risk per year?

CostWatch — Real-time API spend alerts before the bill arrives.

Jenavus — Mon, 23 Mar 2026 04:57:01 +0000

The Problem

Startups don't see their API costs breaking down by endpoint, service, or customer until the bill hits—often revealing $20k+ surprises too late. Existing monitoring tools charge per-host and don't isolate API cost attribution. Teams are flying blind.

What We're Building

CostWatch gives you a real-time dashboard showing exactly which endpoints, services, and customers are driving costs. Drop in our lightweight SDK (Python/JS/Go), connect your cloud provider, and get Slack alerts the moment spend spikes 20% above baseline. We do the math so you don't have to.

Who It's For

Founders and engineering leads at seed-to-Series B startups ($1–10M ARR) with $5k–50k/month cloud spend, especially those using AWS, GCP, or multi-vendor stacks.

Key Features (Planned)

Real-time cost breakdown by endpoint, service, and customer
Lightweight SDK (Python, JavaScript, Go) with zero config overhead
Slack alerts when spend spikes 20% above baseline
One-click integration with AWS, GCP, and Stripe
Cost forecasting and anomaly detection (rule-based, no ML overhead)
Historical trends and per-customer profitability dashboards

We're validating this idea before writing a single line of code. If this resonates with you, we'd love your feedback:

How much visibility do you actually have into your API costs today—are you surprised by bills, or do you catch overages before they hit?
